Care Guide

Watering

Keep soil consistently moist but not waterlogged; increase frequency during hot, dry spells

Fertilization

Apply a balanced, acidic fertilizer once monthly. Avoid over-fertilizing, which can burn roots and reduce berry production in subsequent seasons

Eggshell powder topdress:Crush dried eggshells into a fine powder; sprinkle lightly around the base and water in to boost soil calcium and slightly reduce acidity over time
Pruning
  • Thin overcrowded branches in late winter to improve airflow and light penetration
  • Remove dead or diseased wood to maintain plant health and appearance
  • Shape the shrub after fruiting to preserve desired form; avoid heavy pruning that reduces next year's berry crop
