Fertilization

Light low-phosphorus feed once in early spring. Avoid high-nitrogen fertilizers to prevent excessive foliage growth over blooming

Composted eggshell powder:Crush dried eggshells to fine powder; mix 1 part powder into 10 parts topsoil in early spring to improve soil structure and add calcium
Pruning
  • Prune lightly immediately after flowering to maintain compact rounded shape
  • Remove dead, damaged, or crossing branches to improve airflow and reduce disease risk
  • Thin dense inner growth to encourage better light penetration and blooming the following season
