Watering, pruning, propagation, and repotting details from plant data
Water thoroughly when the soil is completely dry. Avoid overwatering, which can lead to root rot. Reduce watering in winter.
Pruning is generally not required. Remove any dead or damaged parts to maintain health and appearance. Propagate by offsets or seeds.
Easily propagated from offsets (pups) that grow at the base of the plant. Seeds can also be sown in well-draining soil mix.
Repot every 2-3 years or when the plant outgrows its container, preferably in spring. Use a slightly larger pot with fresh, well-draining soil.
