Care Guide

Watering

Water deeply when the top 2 inches of soil become dry.

Fertilization

Apply a light layer of compost or balanced organic matter.. Requires minimal feeding; over-fertilizing reduces fruit yield.

Banana Peel Tea:Steep chopped banana peels in water for 24-48 hours. Dilute 1:1 with water and apply to the base to support root health and vibrant berry development. Discard peels in compost to avoid attracting pests.
Pruning
  • Aggressive Control: Prune heavily in late winter or early spring to control its size and invasive spread;
  • Runner Removal: Continuously remove unwanted runners and ground shoots during the growing season;
  • Deadheading: Remove berry clusters before they are eaten by birds if you wish to prevent seed dispersal in non-native regions.
