Care Guide

Watering

Water every 7–10 days during active growth; increase frequency during prolonged heatwaves

Fertilization

Apply balanced slow-release fertilizer once at the start of growing season. Avoid high-nitrogen fertilizers to prevent excessive foliage growth at the expense of flowering

Eggshell powder top-dressing:Crush fully dried eggshells into fine powder; sprinkle 1–2 tbsp around the plant base and work lightly into topsoil to avoid pest attraction
Pruning
  • Thin overcrowded branches in late winter to improve airflow and light penetration
  • Trim to maintain desired rounded or hedged shape immediately after flowering
  • Remove dead, damaged, or diseased stems as needed throughout the year
  • Avoid heavy pruning, as it may reduce flowering in the following growing season
