Watering

Keep soil consistently moist during active growth; avoid drought stress

Fertilization

Apply balanced slow-release fertilizer once at the start of growing season. Avoid over-fertilization to prevent excessive foliage growth at the expense of blooms

Eggshell powder + banana peel tea:Crush eggshells into fine powder and mix into topsoil; steep banana peels in water for 3 days, dilute 1:20 for root drench to boost flowering and fruit development
Pruning
  • Prune faded blooms promptly to encourage new flower growth and extend blooming period
  • Thin overcrowded branches in late winter to improve airflow and reduce disease risk
  • Trim unruly stems to maintain a compact, rounded shape; avoid heavy pruning during active growing season
