Care Guide
Water deeply but infrequently, allowing the soil to dry out completely between waterings.
Apply a light, balanced, slow-release fertilizer in early spring if soil is very poor.. Requires very little feeding; over-fertilizing can reduce flowering and cause weak growth.
Coffee Grounds Soil Amendment：Mix a small amount of used, cooled coffee grounds into the topsoil to maintain slight acidity and improve drainage; avoid thick layers to prevent mold.- Lightly shear back immediately after flowering to maintain a compact, bushy shape;
- Avoid cutting hard into old, leafless wood as it may not regenerate;
- Remove any dead or damaged stems in late winter.
