Care Guide

Watering

Maintain even soil moisture; increase frequency during berry ripening to prevent fruit split

Fertilization

Apply acidic, slow-release fertilizer when new growth emerges. Avoid high-nitrogen fertilizers that promote leaf growth over fruiting

Composted pine needle + coffee grounds mix:Mix fully composted pine needles and coffee grounds; work into topsoil to maintain acidic pH; avoid raw materials to prevent mold or pest issues
Pruning
  • Prune dead, diseased, or crossing branches in late winter before new growth begins
  • Thin overcrowded interior branches to improve air circulation and sunlight penetration
  • Remove low-growing suckers to maintain an upright, manageable shrub form
  • Trim back old, non-fruiting wood to encourage new fruiting branches
