How to Grow and Care

Alluaudias are succulent plants and need full sun or high interior lighting with a very well drained soil mix and freely circulating air. Plants are watered and allowed to dry thoroughly before watering again. If fertilizer is used, it should be diluted to ¼ the recommended rate on the label. Alluaudias must be protected in the greenhouse over the winter but established plants should tolerate temperatures as low as 32° F (0° C). During the winter months, the plants will drop all of its leaves and no water should be given during this period. If planted in the landscape however, it will often drop all its leaves when it decides to take a rest. When this happens, cut down on the watering until the leaves start to appear again… – See more at: How to Grow and Care for Alluaudia
