How to Grow and Care
These plants are often grouped with Haworthias because the plants have similar cultural requirements. Both are attractive, small succulents that can tolerate more shade than many succulents, making them more suitable as houseplants.
Gasterias are susceptible to fungal infections, which usually appear as black spots on the leaves. These result from too much humidity or water on the leaves, but they should not spread too quickly. They have a natural defense mechanism against such fungal attacks, attack the invading organism, and seal off the wounded spot. In general, any place where Haworthia and Aloe thrive will be hospitable to a Gasteria.
These succulents are small, shallow-rooted, and relatively slow-growing. Therefore, they are often grown in small clusters in wide, shallow dishes. Over time, clusters will naturally enlarge as the mother plant sends off small plantlets.
