Where to grow desert rose

Desert roses thrive in bright locations with high temperatures during spring and summer. In the UK they're usually grown indoors – ideal for a glasshouse, bright room or conservatory. However, they can be grown outdoors in a sheltered spot if the night-time temperature remains above 10℃.

Desert rose is more likely to flower when it gets several hours of sunlight a day. Avoid midday sun, especially if you have left your plant outdoors, as it can scorch the leaves. Placing your plant in a sunny spot will also reduce the risk of over-watering and root rot. Don't place desert roses in low-light areas as they won't thrive.

How to plant desert rose

Choose a pot that is slightly larger than the plant's rootball and has drainage holes at the bottom. Use a free-draining compost mix, with added sharp sand or pumice, to fill the pot, leaving enough room for the plant's roots. Place the plant in the centre of the pot and cover the roots with compost, firming it gently. Water the plant thoroughly and place it in a sunny location.

If you want your desert rose to produce a vibrant display of blooms, keep the plant slightly pot-bound. Then repot it every three to four years in spring, using a peat-free cactus and succulent potting mix.

How to care for desert rose

Watering Water consistently during spring or summer. Let the soil fully dry out before watering your plant, and reduce the frequency of watering in autumn and winter.

Feeding Use a cactus fertiliser every two months when the plant is growing and every three months when it is dormant through winter. This will give it the essential nutrients it needs to thrive.

Encourage flowering Provide a cool and dry dormant period from autumn to early spring with infrequent watering and a few hours of direct sunlight daily. Maintain an ideal temperature fluctuating between 12-15℃. From mid-spring, increase watering and use a potassium-based fertiliser. Deadhead regularly.

Protect Desert rose is not hardy, so protect it from frost and cold temperatures by bringing it indoors.

How to prune desert rose

Prune desert rose in early spring before new growth appears. Remove any dead, damaged or crossing branches, and shape the plant as desired. It can also be pruned to control its size. However, do not remove more than a third of the plant's foliage at once. Remove any yellow or wilted leaves, as well as plant debris. Use clean scissors or shears to minimise the risk of bacterial or fungal infections. Avoid cutting through yellowed tissue as this can lead to infections or disease.

How to propagate desert rose

Desert rose can be propagated from stem cuttings or seeds:

From a cutting Cut a stem that is at least 8cm long in spring or summer. Wet the cut end and dip it in rooting hormone. Place in a small pot of compost – use a cactus and succulent potting mix, and a pot with good drainage to prevent rotting. Keep the cutting in a bright, warm place, at a temperature of about 20℃. Water it enough to keep the soil slightly moist, but let the top half dry out between waterings. It can take two to eight weeks for the roots to form. You will know if the cutting has rooted if the leaves are green and firm, and you see small roots coming out of the dried cut end. After about 12 weeks, you should see new leaves growing. When the new growth is strong, move the cutting to a bigger pot and care for it like an adult plant with the tips above.

From seed Sow seeds about 1cm deep in cactus and succulent potting mix. Keep the soil moist but not wet and let the extra water drain out of the pot. Put the pot in a clear bag to keep the soil moist for longer and place it somewhere bright but not sunny, with a temperature around 25℃ and some heat from below. It might take two to eight weeks for the seeds to germinate. Take off the bag when the seedlings have their third leaf and move them to their own 5cm pots after another month.

Growing desert rose: problem solving

Red spider mites Spinning tiny webs near bleached leaves – these are red spider mites. Mist the plant to raise humidity, as red spider mites thrive in dry conditions, and try a biological control if it's a large infestation
Mealybugs These woolly, white insects can be found clinging to stems damaging your plants. Remove with tweezers if there aren't too many, try a biological control or use a soapy spray.
Scale insects These appear as tiny brown barnacle-like dots on plants, sucking sap and weakening plants. Treat as for mealybugs.
Withered stem, yellow leaves, stunted growth and dry, brittle patches on leaf edges These are signs of sun-scorch, overheating or under-watering. Move the plant to a shadier spot and water it more often. You can also repot it into a larger pot with moist compost to help the roots stay hydrated. Keep in mind that the brighter the location, the more frequently you'll need to water.
Stunted growth, yellowing leaves, lack of new growth, caudex (thick stem) is brown and soft Signs of root rot, due to the soil being too wet or waterlogged for a long time. Remove the plant from the pot and check the roots. If they are brown and mushy, cut them off and replant the plant in fresh, dry compost; if they are yellow, then they are healthy and can be repotted as normal.
Yellowing leaves that then fall off This is a sign of watering, light or fertilisation problems. Adjust the watering schedule according to the season and the soil moisture. Provide bright but indirect light for the plant. Feed once a month during the growing season with a balanced fertiliser.
No flower buds or flowers on the plant A sign of an insufficient dormant period, where the temperature is too constant throughout the year. Lower the temperature by a few degrees during the dormancy period and reduce the watering frequency. As spring arrives, increase the temperature, water and fertiliser to encourage flowering.

Advice on buying desert rose

When buying desert rose, choose a plant with healthy leaves and a well-developed root system. Avoid plants with yellowing or wilting leaves, as they may be stressed or diseased
Check the plant for pests or signs of damage, such as spots or holes in the leaves
