Care Guide

Watering

Water deeply once a week or when the top 2-3 inches of soil are completely dry.

Fertilization

Apply a balanced, slow-release fertilizer just before new growth begins.. Avoid over-fertilizing, especially with nitrogen, as it can promote excessive foliage at the expense of fruit.

Banana Peel and Eggshell Powder:Bake and crush eggshells into a fine powder, mix with chopped, dried banana peels. Scratch lightly into the topsoil around the drip line to support root health and fruiting. Avoid using wet peels to prevent mold and pests.
Pruning
  • Prune in late winter or early spring before new growth begins;
  • Remove dead, diseased, or crossing branches to improve air circulation;
  • Thin out the center of the canopy to allow sunlight to penetrate, which encourages fruiting;
  • Keep the tree at a manageable height for easier harvesting and structural integrity.
