During the growing season, adeniums can be watered as often as several times a week or even daily, depending on the soil mix that is used, lighting and the outside temperature. Larger pots can be watered less frequently, such as every two weeks or so during the peak growing season.
Bone meal fertilizer is rich in phosphorus and a good choice for feeding desert rose Adeniums.
Adenium plants appreciate bright light, but they cannot tolerate direct, scorching sunlight.
Temperature preference: Hot, tropical 75°F–95°F. Chill tolerant (55°F–35°F): Yes, but leaf yellowing and leaf drop may occur. Freeze tolerant (below 32°F): No. During cold winter months, withhold water from Adenium and let the plant rest for 3–4 months.
Put simply, remove the plant carefully from its container. You may need to cut or break it away from its root mass. Once you have the root ball free, simply set it into a new container, the next size up and fill around it with a good quality cactus mix or other sharply draining soil mixture.
