Care Guide

Watering

Water deeply once a week, increasing frequency during extreme heat or fruit swell.

Fertilization

Apply a balanced fertilizer just as buds begin to swell.. Avoid heavy nitrogen applications late in the season, as this promotes vulnerable new growth before frost.

Banana Peel Tea:Steep chopped banana peels in water for 24-48 hours. Dilute the liquid 1:1 with water and pour around the drip line of the tree to support blooming and fruit development. Discard the solid peels in a compost bin to avoid attracting pests.
Pruning
  • Timing: Prune in late winter or early spring while the tree is still dormant;
  • Structure: Train to an open-center (vase) shape to allow sunlight and air circulation into the canopy;
  • Maintenance: Remove dead, diseased, or crossing branches;
  • Thinning: Thin out young fruit in early summer to prevent branch breakage and encourage larger, sweeter individual fruits.
⚠️

Toxicity

Warning: this plant may be toxic.

Pets & Humans

Pets: Toxic per ASPCA. Stems, leaves, and seeds contain cyanide, which is highly toxic to cats. The fleshy fruit itself is not the primary concern, but the pit is dangerous.

Humans: The fleshy fruit is completely safe and edible. However, the seeds (pits), leaves, and stems contain cyanogenic glycosides which can be toxic if chewed and ingested in large quantities.
