Allow the soil to dry out completely between waterings. Overwatering is the most common cause of problems. Water thoroughly when the soil is dry, and ensure good drainage to prevent root rot.

Reduce watering significantly during winter dormancy.

Pruning is generally not required for Haworthiopsis viscosa. Remove any dead or damaged leaves as needed to maintain the plant's appearance and health.

If the plant becomes too large, propagation is a better option than pruning.

Propagate Haworthiopsis viscosa through offsets (pups) that grow from the base of the mother plant. Carefully remove offsets with a clean knife when they are a few centimeters tall, allow the cut end to callus for a few days, and then plant in well-draining soil.

Repot every 2-3 years or when the plant outgrows its container. Use a well-draining succulent or cactus potting mix. Choose a pot that is only slightly larger than the current root ball.

Repot in spring when active growth begins.
