Care Guide

Watering

Water thoroughly when the top two inches of soil feel dry.

Fertilization

Apply a light, low-phosphorus organic top dressing.. Adapted to nutrient-poor soils; avoid heavy chemical fertilizers, especially those high in phosphorus.

Coffee Grounds Tea:Steep used coffee grounds in water overnight, strain, and use the liquid to water the plant. This provides a gentle nitrogen boost and helps maintain the slight soil acidity it prefers without overloading it with phosphorus.
Pruning
  • Prune lightly immediately after flowering to maintain a compact shape;
  • Remove any dead, diseased, or crossing branches to improve air circulation;
  • Avoid heavy pruning, as it may reduce the next season's blooms.
