House plants – Gardens Illustrated https://www.gardensillustrated.com Fri, 17 Mar 2023 08:16:04 +0000 en-US hourly 1 Do you really need to mist your house plants? https://www.gardensillustrated.com/plants/house-plants/misting-house-plants-necessary/ Wed, 15 Feb 2023 08:45:27 +0000 https://www.gardensillustrated.com/?p=100577

House plant books and websites often advise us to mist our house plants to raise the humidity around them, avoiding the brown leaf tips and crispy leaves associated with dry air. But house plant experts are now saying that this technique has little positive effect on house plants.

Dr Stu Farrimond, author of The Science of Gardening, to be published in March 2023 by Dorling Kindersley, is of the opinion that misting plants is ineffective. In the book, he states: “Misting plants with water spray is a common way to raise humidity, although its effects are very shortlived: droplets settle on leaves and gradually evaporate, briefly increasing the humidity around them, before the moisture dissipates into the room. On dry winter days, water droplets may only linger for 10-15 minutes, meaning that hourly spraying would be needed to have any impact.”

Misting a plant with a spray bottle is pretty pointless if you are doing it to increase humidity.
Sarah Gerrard-Jones

Sarah Gerrard-Jones, author of The Plant Rescuer, published by Bloomsbury in 2022, echoes Dr Stu’s thoughts, and does not recommend misting in her book. She told us: “Misting a plant with a spray bottle is pretty pointless if you are doing it to increase humidity. It isn’t really a beneficial activity for your plants and may increase the risk of bacterial and fungal infection, particularly to hairy-leafed plants such as African violets and begonias, which are susceptible to powdery mildew and fungal bacteria caused by moisture on the leaves.”

We also asked Guy Barter, chief horticulturalist at the RHS, for his opinion. He said: “When you mist a plant, the water vapour produced has a highly transient effect on humidity. Any water applied will swiftly evaporate, disperse as vapour and have limited effect.”

It also appears that we do not need to worry about humidity levels in our homes anyway. Many house plants hail from rainforests, where humidity is very high, but this does not mean that they cannot cope with the lower humidity in our homes.

It appears that the traditional dish of damp pebbles, placed under a house plant to raise humidity around it, is pretty pointless

Guy Barter says: “Most UK homes are apparently at 40 per cent to 50 per cent relative humidity in most parts of the house, which is more or less what houseplants will be happy with. I would be surprised if the humidity in an average dwelling is very low – what with cooking, bathing, breathing and so on, excess condensation might be expected to be more common.” Sarah Gerrard-Jones echoes this: “The level of humidity in my house isn’t something I ever lose sleep over.”

Guy advises: “House plants have been chosen to tolerate dry atmospheres, so it is wise to choose ones with notable tolerance where the air is especially dry, usually in warm rooms, such as Sansevieria. Another remedy is to open the window – not a great idea in winter but on warm days in other seasons, the outdoor air is much more humid than indoors.” And of course, some humidity lovers, such as Adiantum raddianum, are perfect for a closed terrarium.

It appears that the traditional dish of damp pebbles, placed under a house plant to raise humidity around it, is pretty pointless, too. Dr Stu Farrimond says: “Pebble trays are frequently recommended to keep indoor plants happy. The theory goes that evaporation from a shallow tray or dish filled with water and pebbles will increase the humitidy in the air around plants standing on the pebbles. In reality, however, it does nothing to help the plant. The humid air just above the water doesn’t rise straight up, but idffuses in all directions, meaning that the humidity at the height of a plant’s roots and leaves is essentially unchanged. ”

Sarah Gerrard Jones echoes this view, as does Guy Barter, who told us: “Wet surfaces such as pebbles will release water but it will swiftly disperse and have limited effect.”

Guy also says that brown leaf tips or leaves, often thought to be a sign of low humidity, can have several other causes. “Excess temperature or draughts lead to more rapid water loss than can be replenished from the roots. So a cooler, less draughty room might be in order. Underwatering or indeed overwatering may also have occurred, where the airless roots will not efficiently pick up water.”

So before you blame low humidity and reach for the spray bottle, check what else may be ailing your plants.

Pot-et-fleur: a display built around aspidistra https://www.gardensillustrated.com/plants/pot-plants/pot-et-fleur-aspidistra-display/ Sat, 11 Feb 2023 11:32:41 +0000 https://www.gardensillustrated.com/?p=18164

The Victorians loved to show off, and table centrepieces became increasingly extravagant throughout the 19th century, often displaying a cornucopia of newly introduced houseplants teamed with exotic blooms and fruit. I wanted to capture a little of that dark and moody flamboyancy against the rich olive green of this wall. The arrangement was built around an aspidistra, the epitome of Victorian houseplants, combined with a selection of deep-green plants with similar and contrasting leaf textures.

Pot et fleur with aspidistra How to achieve the look

A glazed Victorian wash bowl, is ideal for this flamboyant display. It has no drainage holes, so won’t leak on to furniture, but will need careful watering. To begin, I lined the bowl with expanded clay pellets to absorb excess water then added a propriety houseplant compost mixed with extra charcoal. I placed the houseplants in the compost but kept the cheese plant (Monstera deliciosa) in its own pot for ease of removal, as it will quickly outgrow the display. Finally, I sank four thin-necked glass vases in the gaps, before top dressing with additional clay pellets.

The aspidistra copes well with shade, as do the other houseplants, inlcuding x Fatshedera lizei ‘Pia’, a cross between Fatsia japonica and Hedera helix. I placed two trailing peperomia at the front of the bowl to cascade over the lip. For foliar contrast I added a maidenhair and an asparagus fern.

The clean lines of the polygonatum’s tall, arching stems embellished with pendent flowers sits perfectly above the fading flowers of Helleborus x sahinii ‘Winterbells’, which take on a greener hue with age. The ridged, clean stems of Equisetum hyemale add a vertical contrast to the composition.

The arrangement needs a spot away from direct sunlight and regular misting. Overwatering is often the cause of a plant’s demise, so always check the compost before watering. If you don’t trust your finger use a water indication stick. Houseplants benefit from a weekly balanced liquid feed in the growing season, but too much nitrogen can lead to weak sappy growth.

Equipment you’ll need

  • Traditionally, ornate punch bowls or soup tureens were used to hold elaborate, pot-et-fleur designs but any container could be adapted for a more contemporary approach including terracotta and ceramic bowls, willow baskets, glass aquariums or metal boxes, but if it’s not water tight, you’ll need to take care to protect the surface it sits on.
  • Within the main container you can use any sealed vessel to hold the cut flowers but if it will be partially visible, opt for more attractive containers, such as old ink pots or vintage glass bottles that have a wide base and thin neck. Glass test tubes are a good option but take care when burying them in case they break, and always secure safely.
  • A pin holder is an excellent way of accurately securing heavy stems. These discs of metal spikes are much relied on in the practice of ikebana, the Japanese art of flower arranging, lending a more naturalistic feel to an arrangement. I also use several heavy, semi-spherical glass frogs to hold flowers and branch stems. Be sure to attach both of these securely to the base of the vase with floral putty or tape before arranging. A length of wide-gauge chicken wire scrunched into a loose ball will do a similar job. Sharp scissors or secateurs are also essential bits of kit; thorn and leaf strippers are useful too.
  • Before you start arranging your cut flowers, snip off the ends of picked stems and remove any foliage that will be below the water level and leave in deep water for up to 24 hours. Regularly topping up water levels or changing the water entirely every couple of days will help the arrangement last longer as air locks and bacteria will quickly cause a stem to wilt.
  • Houseplants are easily killed through overwatering, so using hydroleca clay expanded pellets will not only add an attractive finish to the container, they will also absorb extra water, slowly releasing it as the compost dries out. They help maintain a humid microclimate around the plants when wet and even out fluctuations in the surrounding temperature. Activated charcoal is another useful addition to the growing medium as it reduces the build up of impurities minimising odours.
  • Propriety brands of houseplant potting compost with an open, free-draining mix should be sufficient for most growing needs but you can improve drainage by adding perlite, vermiculite, horticultural sand or grit. A top dressing of decorative gravel, clay pellets or moss will also reduce water loss.
  • A slim watering can with a long narrow spout for small spaces is ideal for these displays, but misting is an excellent way to maintain the humidity around plant leaves.

Large indoor plants: 15 of the best https://www.gardensillustrated.com/plants/house-plants/large-indoor-plants-best/ Tue, 07 Feb 2023 10:16:45 +0000 https://www.gardensillustrated.com/?p=100112

A large indoor plant can instantly transform the look and feel of a room, breathing life into the space and making it feel lush, calm and welcoming.

There are many large house plants to choose from, from palms that give a lush feel to plants with large leaves that make a real statement, such as a Swiss cheese plant, rubber plant or bird of paradise.

Advice on choosing a large indoor plant

Before choosing a large indoor plant, assess your space. Do you need to fill a tall, thin spot, or do you need to fill a larger empty area?

Think carefully about light. Most house plants do best a few feet from a window. Larger leaved plants are adapted to coping with lower light levels, but bear in mind that any plant will struggle in a dark corner. Some plants, such as the fiddle leaf fig, do not like to be moved around, so choose its permanent spot carefully.

Make sure you’ve checked how fast your chosen plant grows, and its ultimate height and spread. For instant impact, buy the biggest plant you can afford.

Once you’ve chosen your plant, you’ll need to find the right pot to complement it. Read our feature on the best ceramic plant pots.

How to water large indoor plants

Check the watering needs of your chosen plant. Most need watering when the top few centimetres of compost is dry, but some, such as Euphorbia trigona, can survive on less.

Repotting large indoor plants

The larger your plant pot and the bigger the plant, the harder it can be to repot a plant. If the whole operation is proving too tricky, there is a simple solution. Simply scrape away as much of the compost as you can with a spoon or fork – at least 5cm, taking care not to damage the roots – and replace it with fresh. You can do this every year, in spring.

Large indoor plants: the best to grow

Swiss cheese plant, Monstera deliciosa

Monstera deliciosa ‘Variegata’
© Jason Ingram

If it’s big leaves you’re after, they don’t come much bigger than those of a Swiss cheese plant (Monstera deliciosa). This Seventies classic is back in fashion again, and has much to offer, with its dramatic and glossy and holey leaves. A variegated variety, Monstera deliciosa ‘Variegata’, is also available. A Swiss cheese plant will sprawl, so is best grown up a mossy pole. After a while, many people find that their plant outgrows their space (in the wild it can reach 25m tall, and will ultimately reach around 8m in a house), and pass it on. But in the meantime it has a lot to offer, and is usually problem free.

Ultimate height and spread: 8m x 2.5m

Best for: big leaves and a large space

Bird of paradise, Strelitzia reginae

The bird of paradise plant (Strelitzia reginae) has striking blue-green, paddle-like leaves that bring an exotic look to any space. If the conditions are right, when it reaches around four years old, it will produce a flower that looks like the plumage on the head of an exotic bird. It enjoys humidity, so is ideal for a bathroom. Alternatively, stand on a tray of pebbles or gravel topped up with water.

Ultimate height and spread: 1m x 60cm

Best for: an exotic look, bathroom

Yucca, Yucca elephantipes

Yuccas have a spiky and architectural look that suits a modern, minimalist room or a small space, as they are usually tall and narrow. They’re tough and tolerant of neglect, so are a good low maintenance option. Water only very sparingly in winter. Avoid placing the sharp leaves at eye level, as the pointed ends of the leaves are sharp.

Ultimate height and spread: 1.5m x 75cm

Best for: low maintenance, minimalist look, tight spot

Sago palm, Cycas revoluta

Actually not a palm but a cycad, the sago palm has an uncluttered, architectural look and graceful arching foliage. It is a good low maintenance option as it can  cope with some neglect and doesn’t need much watering.

Ultimate height and spread: 1.5m x 1.5m

Best for: low maintenance, contemporary look

Fiddle leaf fig, Ficus lyrata

Social media went crazy for the fiddle leaf fig a few years ago, and it remains a popular choice. It’s beautiful leaves are said to be the same shape as that of a fiddle. The fiddle leaf fig hails from western Africa, and can be a little temperamental in its needs – it does not appreciate being moved around and prefers temperatures on the warm side – don’t let them drop below 12°C, try to keep them consistent and keep away from cold draughts. The fiddle leaf fig also appreciates some humidity, so mist the leaves from time to time or stand on moist pebbles. One for a more experienced house plant owner.

Ultimate height and spread: 1.8m x 1.2m

Best for: unusual leaves, experienced house plant owners

Kentia palm, Howea forsteriana

The Kentia palm has fresh green leaves that fan out from tall stems, bringing a lush look to any room. It’s tolerant of lower light levels and is pretty easy to care for, making it a good choice for beginners.

Best for: beginners, an elegant look

Ultimate height and spread: 3m x 2m

African milk tree, Euphorbia trigona

Euphorbia trigona is an unusual succulent that originates from Western Africa. With its upright stems, it makes an architectural statement in a room. It is thorny and has a milky sap, so keep out of the reach of children and pets. It needs a warm, bright spot away from draughts and is drought tolerant for short periods.

Ultimate height and spread: 1.8m x 50cm

Best for: a bright spot, low maintenance

Rubber plant, Ficus elastica

Rubber plants have been popular house plants for decades and new varieties, such as Ficus elastica ‘Robusta’ have bigger, more dramatic leaves. They are easy to care for – just give them a bright spot out of direct sunlight and water when the top few centimetres of compost are dry. Wipe the leaves from time to time to keep them dust-free and glossy.

Ultimate height and spread: 3m x 75cm

Best for: large leaves, beginners

Sansieveria cylindrica

We’re all familiar with the mother-in-law’s tongue, Sansevieria trifasciata, but its cousin Sansevieria cylindrica is an interesting choice. It has tall, upright, cylindrical and striped stems that look great in a modern home. It is incredibly low maintenance and tolerant of neglect – sansevierias are hard to kill.

Best for: a tight spot, low maintenance

Ultimate height and spread: 1.2m x 50cm

Devil’s ivy, Epipremnum aureum

This climbing (or trailing) house plant has many different names – Scindapsus, pothos or Devil’s ivy. It is one of the easiest house plants to grow. It has attractive, heart-shaped leaves and will climb upwards if you provide it with a support such as a mossy pole. Some have variegated or splotched leaves, or golden yellow foliage.

Best for: a tight spot, low maintenance

Ultimate height and spread: 2m x 30cm

Areca palm

The Areca Palm also goes by the name of golden cane palm and yellow palm, thanks to its yellow stems. It is also know as the bamboo palm or butterfly palm. It forms a fountain of delicately arched fronds. Areca palms like humidity, so a bathroom is the perfect spot for them. Alternatively, mist the leaves regularly.

Best for: a lush feel, bathroom

Ultimate height and spread: 1.8m x 75cm

Parlour palm, Chamaedorea elegans

The parlour palm was a familiar sight in Victorian drawing rooms, and it’s still popular house plant today thanks to its graceful, arching fronds and elegant look. It likes a bright spot and appreciates some humidity, so mist the leaves regularly.

Ultimate height and spread: 2.5m x 1.5m

Best for: a lush feel, bathroom

Philodendron xanadu

If you want a wide house plant with bold leaves that doesn’t get too tall, Philodendron xanadu is the choice for you. It has attractively lobed leaves and red stems, and brings a jungly look to a space. It’s pretty low maintenance, too.

Best for: a wide area

Ultimate height and spread: 1m x 1m

Dragon plant, Dracaena marginata

The dragon plant, Dracaena marginata, has strappy foliage that is attractively edged with red and sits on top of tall, thin woody stems. It is a slender plant, so is the perfect choice for a tight spot. A dragon plant can last for years but grows slowly, so if you want instant impact, treat yourself to a larger, established plant. Dragon plants are undemanding and prefer to be underwatered rather than overwatered, so let the top few centimetres of soil dry out before watering again. They are ideal for beginners or house plant owners with little time.

Read our expert guide to growing a dragon plant.

Ultimate height and spread: 2m x 30cm

Best for: a tight spot, beginners

 

Weeping fig, Ficus benjamina

A weeping fig is a light and airy addition to a room, with gently arching stems of dark green or variegated leaves. It needs the right conditions, otherwise it may drop its leaves – avoid under or overwatering, moving it around or repotting it too often.

Ultimate height and spread: 3.5m x 1.2m

Best for: light and airy look, experienced house plant owners

The art of pot-et-fleur: combining houseplants with cut flowers https://www.gardensillustrated.com/plants/pot-plants/pot-et-fleur-flower-arranging-display/ Mon, 06 Feb 2023 12:58:21 +0000 https://www.gardensillustrated.com/?p=18123

I love using wildflowers in naturalistic floral arrangements and grow as many as possible in my own garden so that I am free to pick as desired. This arrangement was inspired by a walk down my local country lanes in May where the hedgerows are lined with billowing clouds of cow parsley, Anthriscus sylvestris, exuding a light and airy feel. I’ve combined this iconic umbellifer with several Adiantum ferns and a trio of blues from the borage family to add some sparkle to the mix.

Pot et fleur how to achieve the look

This handsome wooden crate houses ten chunky soda bottles, but for this display I replaced seven of them with maidenhair ferns in 1L pots and three with cut flowers in glass vases, anchoring the arrangement with a row of Victorian clay ink pots.

A selection of tall, cow parsley stems adds height, and I picked those with the darkest purple stems to match the rose-flushed buds of the Clematis montana. These provide a link to the almost-black stems of the maidenhair fern, whose fresh virescent tones add a sense of depth to the display.

Green alkanet, Pentaglottis sempervirens, and Siberian bugloss, Brunnera macrophylla, provide a drift of bright blue that is subtly enhanced by the chalkier blue of forget-me-not, Myosotis sylvatica. This arrangement will last nearly two weeks in a cool conservatory out of direct sunlight with regular misting and changes of water in the vases. The ferns appreciate high humidity and should be kept well watered during the growing season.

All the flowers used in this display are prolific self-seeders so need careful management to stop them taking over your garden. The hairy leaved alkanet can be found flowering along woodland edges so is happy in part shade while the bugloss makes a great groundcover plant. I cut both hard back in June and July, after their initial flowering to refresh and keep them in check. Myosotis sylvatica also copes well with shade, readily seeding about but is easy to pull out where not required.

 

Plants in the display

1 Pentaglottis sempervirens A perennial herb. Flowers April to July. 70cm. RHS H6.

2 Anthriscus sylvestris Cow parsley.Flowers April to May. 1.7m. RHS H6.

3 Myosotis sylvatica A short-lived perennial or biennial. April to June. 3cm. RHS H6, USDA 3a-8b.

4 Clematis montana A vigorous deciduous climber. March to June. 12m. RHS H5, USDA 4a-9b.

5 Brunnera macrophylla Siberian bugloss, a hardy perennial. April to July. 40cm. RHS H6, USDA 3a-7b.

6 Adiantum raddianum ‘Fragrantissimum’ Tender evergreen fern with black stems and lime-green leaves. 50cm. USDA 8a-11.

House plant display: creating the perfect stylish display https://www.gardensillustrated.com/plants/planting-ideas/perfect-houseplant-display/ Wed, 11 Jan 2023 09:00:53 +0000 https://www.gardensillustrated.com/?p=24230

When planning house plant arrangements, keep plants with similar light requirements together. These exotics, which we cultivate in the conservatory and bring into the house when they reach their prime, have been positioned to take advantage of the intermediate morning light next to a sitting room window.

How to arrange this house plant display

This position avoids the intense midday sunshine that may scorch the foliage. It’s a temporary display, and when the plants begin to look jaded they are returned to the conservatory and replacements found. The orchids take this upheaval in their stride, as do the ferns, and require little more than a light daily misting.

It is vital to avoid crowding them too closely together, otherwise, the display can look congested. Position the larger plants first, work from the back to the front, and try to consider the appearance of both flowers and foliage.

Suitable for use both indoors and outdoors, this large plant pot is a versatile planter to keep at home. It’s made in Portugal entirely from terracotta, and it’s finished with neutral colouring, so it should fit nicely into most décor schemes.

This pot is 21.8cm tall, but there’s also a smaller option, which has a height of just 16cm.

Layered Cement Planter

Characterised by its neutral colour tone and intricately layered cement finish, this pot will add subtle texture to a room. It has a height of 12cm and a diameter of 16cm, so it’s a good size for most house plants, but its bowl-like shape should look particularly good with leafy and trailing varieties.

Set of Three Terracotta Pots in Basket

Another great option for homes with a vintage aesthetic is this set of three rustic terracotta pots. They’re held together neatly with an attractive wire structure, reaching a total length of 37cm. Meanwhile, each individual pot can hold up to 0.3L of soil.

Woven Hanging Plant Pot

You can draw the eye up in any room with beautiful hanging planters like this one from Garden Trading. It’s constructed with seagrass, but there are two other similar styles made from jute available – and all have an internal PVC lining to contain any water drips.

Ferns and trailing plants look especially great in hanging pots, creating a rural, breezy look in your home.

 

Two Textured Standing Planters

If you’re after something special, this pair of burnished gold planters might be the ideal choice. They’re constructed from aluminium and have little tripod legs underneath to keep them off the ground.

The set comes with a small pot, reaching 25cm in height, and a larger planter, which is 29.5cm tall.

H&M Large Mango Wood Plant Pot

H&M’s 100% wood plant pot brings warm tones, and it would look just as good in modern, minimalistic décor schemes as it would with traditional and neutral styles. It reaches 18cm in height, so it’s a good size to add to most table tops and furniture items.

Peperomia: How to grow and care for the house plant https://www.gardensillustrated.com/plants/pot-plants/house-plant-peperomia/ Tue, 10 Jan 2023 10:50:43 +0000 https://www.gardensillustrated.com/?p=14727

Peperomias are not wildly thrilling, but they do have a certain flair,’ writes Tovah Martin in her book The Unexpected Houseplant. Talk about damning with faint praise. She does have a point. Peperomias lack the imposing physicality of a 3m Monstera deliciosa embracing a moss pole, or the peacock patterning of a colourful Calathea, but I adore them for the sheer variety of leaf textures and for their diminutive size. For those without floor space for expansive specimens, peperomias are compact enough to house a sizeable collection on a modest shelving unit or windowsill.

How to care for peperomia

The different types of peperomia

Sally Williams, who holds the National Collection of Peperomia, has a plant room packed with 500 peperomias to tend while her Peak District garden is hidden under a freezing, white blanket of snow. There are familiars, such as the radiator plant (Peperomia caperata), which has crinkled leaves like toes after a long bath, and the watermelon peperomia (Peperomia argyreia) with heart-shaped glossy leaves draped in silver stripes, but I’m drawn to some rarities, too. One with foliage the colour and texture of toad skin is labelled Peperomia hutchisonii, while lifting a misty bell jar reveals a mass of minute leaves strung on the thread-like stems of Peperomia bangroana.

Where are peperomia from?

Sally’s collection demonstrates the diversity and scale of the Peperomia clan. Attempt to discover something seemingly simple, such as how many species are in the genus, and the answer varies from 1,300 to 1,600. Matt Candeias, a botanist and fellow Peperomia lover, tells me that Peperomia is an ancient group of plants that has evolved to thrive in a wide range of environments around the world, with concentrations in Central and South America and in Africa. Why does all this matter to you and me, tending a cluster of watermelon leaves or untangling the stems of a string of turtles (Peperomia prostrata)? Finding out about where your Peperomia hails from helps inform how you care for it.

Best conditions for Peperomia

The vast majority of peperomias you’ll find unhelpfully labelled merely as ‘foliage plant’ in your local supermarket or DIY store grow as epiphytes in rainforests, clinging to clefts in a tree where they enjoy humid air and dappled light. These – including rosette types, such as the watermelon peperomia, and trailers, such as the cupid peperomia (Peperomia nitida) – have modest rootballs and store water in their fleshy stems and leaves. Root rot is the peperomia’s number one enemy: know this, and you’ll find them among the most easy-going and undemanding houseplants you can grow.

How to care for Peperomia

Best soil for Peperomia

Sally raises her plants in terracotta pots, planted in an airy mix of two parts peat-free, general-purpose potting mix, one part orchid bark and one part perlite.

How often to water Peperomia

Sally also keeps the air moist by misting – watering just once a month. Succulent species, such as Peperomia columella, Peperomia ferreyrae and the toadlike Peperomia hutchisonii, generally hail from high altitudes in South America, particularly Peru, adapting to arid conditions and dry air by folding their leaves in half like a taco when water is in short supply: these prefer an even more free-draining, gritty mix and will thrive in a sunny, south-facing window. Rare trailing species, such as Peperomia bangroana, require really high humidity and do best creeping around in a shady, sealed terrarium.

How to propagate Peperomia

The key to successful Peperomia propagation is to know whether your specimen will root from a section of stem, a leaf petiole cutting or even, miraculously – from a section of leaf. The general rule is that rosette-forming types will propagate from a leaf petiole cutting, while trailing peperomias will grow roots from a length of stem.

  1. Take a clear plastic pot with a tight fitting lid – a recycled hummus pot is ideal.
  2. Place a trickle of water so the bottom is just covered and then add the leaf or section of stem, curling it around the edges of the pot if necessary.
  3. Place the lid on and leave on a bright windowsill out of direct sun.
  4. Check every week until roots and shoots have appeared, then pot up into gritty compost.

This method works for most peperomias except succulent types such as Peperomia columella, which can be rooted straight into gritty compost instead.

String of pearls plant: how to care for your Curio rowleyanus https://www.gardensillustrated.com/plants/pot-plants/string-of-pearls-houseplant/ Tue, 10 Jan 2023 08:50:37 +0000 https://www.gardensillustrated.com/?p=23976

Of all the succulents, the string of pearls plant (Curio rowleyanus) is one of the most distinctive and most sought after, adored for its cascade of wiry stems festooned with tiny spherical leaves that look like peas (or beads or pearls, if you are feeling poetic). But if I could do one thing in the service of horticulture, it would be to end the tragic deaths of string of pearls plants at the hands of their owners.

Within weeks, the pearls are shrivelled or turned to mush, and the befuddled owner just can’t fathom why – they watered their plant at the same frequency as their other succulents, placed it in the same sunny windowsill, and yet it will not thrive.

Where the string of pearls plant originated

The string of pearls plant, or Curio rowleyanus (you may recognise it under its previous name of Senecio rowleyanus) is found only in the Karoo shrubland of South Africa’s southern cape although other species are found as far north as Namibia. Despite its characterisation as a trailing plant in cultivation, in the wild string of pearls forms a mat on the ground, often growing beneath and over shrubs and other plants or lodging in cracks in rocks, rooting along its stems where it can find a suitable spot.That provides an important clue as to where things go wrong with this plant in the home: it is adapted to grow in sharply drained soil that is low in humus.

How to care for string of pearl plants

 

When bought from a garden centre or online shop rather than a specialist grower, string of pearls usually arrives in a plastic hanging pot with a built-in saucer, planted into regular house plant compost (if you are particularly unlucky, this will already be sopping wet). It’s not long before poor drainage and spongy soil allows water to build up around the roots, and the plant will start to protest.

Make sure the string of pearl plants are in gritty, well-drained compost

It’s wise to repot plants as soon as possible into a gritty mix of a third to a half grit or perlite and a similar quantity of John Innes No.2. I find a terracotta pot rather than a plastic one helps to keep the roots happy.

When to water string of pearl plants

With these measures in place, plants can be generously watered once a week in summer without risk of damage. From November onwards, cooler temperatures combined with minimal watering keep string of pearls ticking over until spring.

Give your string of pearl plant lots of light

What about light? In the wild this plant doesn’t usually grow completely exposed to the sun, but of course the intensity of the light is hugely greater there than the average sunny windowsill in a British home. My string of pearls plant grows contentedly on a high shelf in my glass-roofed, north-facing sunroom, where it gets lots of bright light: plants may need some shading if they are grown in a greenhouse or outside during the hottest months. The cream-striped variegated form seems more susceptible to sun exposure, so take extra care if you are lucky enough to own one of these.

It seems churlish not to mention the flowers. Small, white inflorescences appear along the stem in summer, making their presence known via a cinnamon scent rather than dramatic looks. They are, however, most likely the only way you’ll ever know that string of pearls is a member of the daisy family (Asteraceae).

How to propagate string of pearls

Once you’ve cracked caring for Curio rowleyanus, you can play Lady Bountiful and root some cuttings for admiring friends. The simplest way to do this is simply loop the stems back on to the surface of the compost until they root and can be snipped away.

Once your plant is happy, and you are no longer afraid to look at it sideways in case it keels over, it is worth examining it more closely. Like many succulents, the string of pearls plant has found a way of adapting to its arid environment through its leaves. Reach back to maths class at school and you may recall that a sphere has the lowest surface area to volume ratio of any shape. By having spherical leaves, string of pearls can store the maximum amount of water possible. At the same time, there’s less surface area through which water loss (transpiration) can occur, and less leaf exposure to the midday sun, reducing the prospect of the leaf getting frazzled by the heat.

But what about photosynthesis, you may wonder – surely reducing the surface area of the leaf means string of pearls won’t receive enough light? The plant has another clever trick for that. Each leaf contains a darker strip that’s visible when held up to the light. This is an epidermal window, which seems to work by allowing light to pass into the inner tissues of the leaf where photosynthesis can occur. I write ‘seems’ as botanists are still investigating exactly how these windows function. These fascinating plants may yet have more secrets to reveal

Asparagus fern: Everything you need to know https://www.gardensillustrated.com/plants/pot-plants/asparagus-fern-indoor-plant-propagate/ Mon, 09 Jan 2023 15:07:32 +0000 https://www.gardensillustrated.com/?p=15733

Pothos pushing under net curtains; red pelargoniums blazing from behind a misted window; palm fronds tapping against glass – I love spotting houseplants. Hairdressers’ windows are a good place to find them. Perhaps it’s the warm fug fostered by hair dryers, but plants seem to thrive in salons. My own hairdresser has just one plant, but it’s a beauty – an asparagus fern that trails from the top of a cupboard near an east-facing window.

How to care for asparagus fern

Is asparagus fern a real fern?

Despite fern-like, frothy foliage, an asparagus fern is not a bona fide fern: asparagus ferns are part of the genus asparagus and cousin of the much-prized vegetable (Asparagus officinalis). If you struggle to grow true ferns, try an asparagus fern. These ferns are invaluable if you find yourself unable to meet the care requirements of, say, a maidenhair fern, whose precise approach to soil moisture (not too wet, not too dry) can test the most attentive grower.

Asparagus ferns’ refusal to wilt, along with their wiry tenacity, has long made them a hit with florists. Celebrity florist Simon Lycett has an office full of photographs of brides past and present holding bouquets with clouds of asparagus ferns. “It’s been a real stalwart of florists ever since we started arranging, certainly from Victorian times,” he says.

Where do asparagus ferns originally come from?

The half-dozen or so species that make up the asparagus ferns commonly raised as houseplants hail from southern Africa, where they grow as understorey plants in dappled light. The tuberous roots that store energy and water to carry the asparagus fern through lean times in the wild make these ferns tolerant of the occasionally aberrant watering regime of the average indoor gardener. Another curious feature is the tiny, scale-like structures on the stems of an asparagus fern: what we assume to be leaves are in fact cladodes, which are flattened stems that can photosynthesise.

Asparagus fern care

Where to put your asparagus fern

When choosing an asparagus fern, it’s important to consider how these plants like to grow. Some species are born to climb. In a garden centre recently, I spotted a lovely specimen of the ubiquitous Asparagus setaceus, the common asparagus fern. At 1m tall it was living its best life, sending out bare, wiry stems to wrap around its pole, before clothing those stems in feathery foliage. Nearby, pots of asparagus smilax  (Asparagus asparagoides) look set to burst the bounds of their tiny trellises and colonise the whole shop. Other asparagus fern forms suit hanging or trailing. My hairdresser’s plant, Sprenger’s asparagus (Asparagus aethiopicus), looks best as a waterfall of wiry stems cascading from a hanging basket, while the foxtail fern (Asparagus densiflorus ‘Myersii’), has plume-like stems and a bushy habit that looks stunning on a plant stand.

One downside is that asparagus ferns have thorns that can scratch mercilessly when repotting, and the thorniest of all asparagus ferns is the sicklethorn (Asparagus falcatus).

Not too dry or hot

Although asparagus ferns may shed their needle-like foliage with abandon if the compost is allowed to dry out too much, or when they are situated somewhere too dry and hot.

The asparagus fern likes a snip

And just follow my hairdresser’s lead and give your asparagus fern a quick trim with a pair of scissors if it starts to get out of bounds.

The best pot for an asparagus fern

A heavy, terracotta pot has two advantages when it comes to an asparagus fern: those ferns with a trailing habit are less likely to topple, and plants are not prone to succumb to yellowing fronds owing to overwatering, as excess water can evaporate away through the porous pot. When it comes to dividing, however, plants in clay pots can prove a challenge.

How to propagate asparagus fern

Late winter or early spring is a good time to tackle this task. First, give the plant a good soak in water for an hour. Then, wearing thick gloves to protect from thorns, work an old palette knife around the edge of the pot to loosen the rootball (many a terracotta pot has been smashed as a result of an asparagus fern set like concrete into it). Once the rootball is dislodged, start teasing away at the chunky, white root tubers, separating the plant into equal portions, each with a decent set of roots and foliage. Pot up the asparagus fern individually into houseplant compost with a handful of grit or perlite for added drainage.

As the winter nights grow longer and temperatures drop, I like to remind myself of the hot summer days spent in the garden or travelling abroad. In this pot display the terracotta holds a rustic warmth that is complemented by the cool, monochromatic planting. Succulents are used throughout the entire display and reference their arid growing conditions, hopefully providing an uplifting contrast to the dark days of winter.

How to achieve the look

Container and composition

The container is a classic, simple shape. Most importantly, it has a wide top that allows for a generous arrangement. Warmth comes from the weathered terracotta, its subtle markings echoed in the mottled foliage of the sansevieria. Its glaucous tones are repeated throughout the planting, emphasising the texture and form of the plants while perfectly complementing the soft terracotta. Tinges of dark-red detail on some of the foliage highlight the various leaf shapes and bring a warmth to the planting. Mixing bold plants, such as the kalanchoe and sansevieria, with those of a softer texture, such as the sedum and crassula, provides interesting contrast.

Planting and care

Succulents are relatively slow growing, so be generous when planting and select a suitably sized pot that will look full when planted.

  • Fill the pot with a soil-based compost and added grit.
  • Begin to add plants by positioning the largest specimens first, before gently filling in gaps with smaller plants. Add additional potting mix as you go to ensure plants are held firm and secure.
  • Once complete top dress with horticultural grit to prevent soil from splashing on the plants when watering. Use a narrow trowel, or a hori hori, to help ensure you get the potting mix and grit into difficult, hard-to-reach gaps. Water in well.

These are all tender plants that need a frost-free site, so in winter keep inside in a warm, sunny spot, and water sparingly. The pot could be put outside in late spring, when all risk of frost has passed.
