Care Guide

Watering

Water every 7–10 days during prolonged dry spells; allow top 5 cm of soil to dry between waterings

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 fruit production

Eggshell powder topdress:Crush clean, fully dried eggshells to a fine powder; sprinkle 1–2 tbsp around the shrub's base and water lightly to release calcium into the soil
Pruning
  • Remove dead, damaged, or crossing branches in late winter before new growth emerges
  • Thin overcrowded inner branches to improve airflow and light penetration
  • Shape the shrub in early spring to maintain a rounded, compact form; avoid heavy pruning that removes fruiting wood
