Care and how to grow
There are five varieties of true Desert Rose, and all are native to arid or semi-arid climates, yet they can all adapt well to tropical and semi-tropical settings.
Indeed, these rugged desert dwellers adapt to almost any situation as long as they have plenty of sun and warmth and well-draining soil.
In very hot climates, Desert Rose is happy and prolific outdoors all year round. These plants love to be in the direct sun with temperatures of at least 70°F, but they can do very well in temperatures of up to 100° Fahrenheit.
In North America and other settings where the temperature drops below 40 degrees Fahrenheit for extended periods of time, the plant is abundantly floriferous throughout the warmer months.
The blooms are long-lasting and are attractive to hummingbirds and pollinators such as bees and butterflies. When the weather begins to cool, you must bring your Adenium indoors to enjoy during the winter.
Desert Rose fertilizer
During the growing season, it is a good idea to provide a light feeding of a slow-release fertilizer, or a water-soluble liquid fertilizer from time-to-time. In the springtime when the plant is rousing from its winter rest, you can give a diluted feeding once every couple of weeks. During summer, reduce this to once a month. As the weather cools, stop feeding so that the plant can wind down for the winter.
If you bring your Adenium plant indoors for the winter, you may want to give it one weak feeding in mid-winter; however, this is not necessary as the plant is likely in a state of semi-dormancy.
Is regular pruning necessary?
Because these plants can grow quite large, a combination of pruning and under-potting is essential to keep them at a manageable size. A regular pruning schedule will help keep your plant fresh, vigorous and well-groomed.
During the growing season, pinch back or prune unruly growth. Before bringing the plant indoors for winter, prune back excessive growth as this will make the rest period more effective for the plant. Additionally, it will be easier to keep a smaller, more compact plant indoors during the winter months.
Before putting the plant back outdoors for the growing season, a good trimming is a smart idea. Trim off any dead or damaged vegetation. Cut back straggly branches to improve the plant’s shape. You can use these branches as cuttings to create new plants.
