Follow some basic tips for growing adenium desert roses for a healthy plant that won’t disappoint with a crown full of colorful tubular flowers.
Adenium is a fragrant tropical plant. They differ between classes in that they develop a caduceus, or swollen trunk. All aromatic plants have some form of water storage system, be it leaves, stems, or roots. In desert roses, the stems swell to conserve moisture during drought. A well-fatted stem is an indicator of plant health. Weak stems may indicate that the plant needs more moisture.
An interesting part of desert rose plant information is the natural resemblance to a bonsai plant, with a shorter stature, and a beautiful floor on a terraced stem. Many gardeners seem to find desert rose plants difficult to care for, but care is easy if you keep in mind the water, temperature and light needs of adeniums.
First, remember that adenium plants come from areas with poor, sandy soil and warm, sunny climates. You can’t expect plants to grow in very wet soil in places with limited light. They are also not frost resistant and will freeze if exposed. Plants will not survive as long when exposed to temperatures below 40 degrees F (4 C) but will thrive up to 90 degrees F (32 C).
Desert Rose: Plant Care & Growing Guide
Desert rose succulents love bright light, so a southern window exposure provides the plant with enough sunlight to grow and bloom. In the garden, choose a sunny spot protected from afternoon sun, as this can burn the leaves.
Land is very important. Adenium plants should have cactus soil mixed with sandy loam or lava rock for good drainage.
One thing that will kill this plant quickly is inadequate watering. They are fragrant but accustomed to rainy conditions, in which they grow, followed by periods of drought. Tailor your watering practices to these needs for best success. Keep the soil moderately moist in the spring and summer, but reduce watering in the fall and especially in the winter when plants are dry.
Fertilize with half a mixture of 20-20-20 liquid plant food once a month when the plant is actively growing. Do not feed desert roses in winter.

Desert Rose Bonsai Growing And Care Information
How you prune desert roses is up to you. It depends on how it looks and what size it wants to grow. I’ve seen some great ones with tall stems and branches that have become so short that the flowers are a tight bunch on the stem. In others many long thin stems can be wrapped around each other. You get the idea – it’s a matter of taste.
Good to know: Pruning adenium flowers on new growth will encourage that growth and produce more flowers.
