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.
Uses
Used as a ground cover in gardens, in rockeries, or as a decorative plant in containers. Its spreading habit helps prevent soil erosion.
Notes
Prune back in early spring to control spread and encourage fresh growth. Repot if grown in containers every 2-3 years. Avoid waterlogging to prevent root rot.
