Common problems
Overwatering can lead to root rot and yellowing leaves. Poor drainage or too much shade may cause the plant to become leggy or weak. Occasionally, pests like aphids or mealybugs may appear but are usually easy to control.

Notes
Prune back any leggy growth in spring to maintain a compact shape. Repot every 2-3 years if grown in containers. Avoid letting water sit on leaves to prevent rot.
