Common problems
Overwatering leading to root rot is the most common problem. Insufficient light can cause leggy growth. Pests are rare but watch for mealybugs.
Uses
Primarily grown as an ornamental succulent for indoor decoration and outdoor rock gardens due to its unique leaf shape and drought tolerance.
Notes
Prune any leggy or damaged stems to encourage bushier growth. Repot every 2-3 years to refresh soil and provide space for roots. Protect from frost and temperatures below 5°C (41°F).
