Care Guide

Watering

Maintain even soil moisture; water when the top 1cm of soil feels dry

Fertilization

Diluted organic liquid feed every 2 weeks. Use balanced organic feed to support root and foliage development; avoid high-nitrogen fertilizers that may weaken root growth

Banana peel compost tea:Compost banana peels for 2–3 weeks to break down completely; dilute the tea 1:20 with water before applying as a root drench; discard solid debris to prevent pest infestations and odor
Pruning
