Common problems
Overwatering can lead to root rot and leaf mushiness. Too little light may cause the plant to stretch and lose its compact shape. Pests are uncommon but watch for mealybugs.
Uses
Primarily grown as an ornamental plant for indoor decoration and succulent collections. Its unique leaf texture and form make it a popular choice for rock gardens and container displays.
Notes
Repot every 2-3 years in spring using a well-draining succulent mix. Avoid pruning except to remove dead leaves. Protect from frost as it is not cold-hardy.
