Gasterias are recognisable from their thick, hard, succulent "tongue-shaped" leaves. Gasteria are grown in well-drained, sandy soils in light shade. They can be propagated by off-sets and cuttings. They are also commonly propagated by seed.
Like other succulents, these plants don't need much water. Allow the soil to almost completely dry out between waterings. If the plant gets rainfall outdoors, usually no supplemental watering will be necessary.
As a result, the plant tolerates lower light conditions than many other succulents do, making it a good option for a houseplant.
Fertilize once every spring with a cactus fertilizer. Gasteria plants like a bit more organic matter in their soil than most succulents do, so mixing in a bit of compost at the time of planting can be a good idea.
When taking offsets, use a sharp knife or scissors. Cut as close to the parent plant's stem as you can, including as many roots attached to the offset as possible.
