Care Guide

Watering

Keep soil consistently moist during fruiting season to support berry development

Fertilization

Apply a balanced organic feed once at bud break. Avoid high-nitrogen fertilizers, which can reduce berry production and promote excessive leaf growth

Banana peel compost tea:Use fully composted banana peels, dilute 1:20 with water for root drenching; avoid raw peels to prevent pest infestations and odor
Pruning
  • Prune old, non-fruiting wood in late winter to encourage new fruiting growth
  • Thin overcrowded branches to improve airflow and light penetration for better berry development
  • Remove suckers at the base to maintain plant shape and focus energy on productive stems
