Watering

Eggshell powder topdressing:Crush dried eggshells into fine powder; sprinkle 1–2 tbsp around the tree base and water in lightly to prevent nutrient runoff
Pruning
  • Prune in late winter to remove dead, damaged, or crossing branches and maintain desired shape
  • Trim hedge plants after flowering to avoid removing developing fruit clusters
  • Wear thick protective gloves to avoid injury from sharp thorns
