Seasonal Care Guide

Early Summer (Jun 1 – Jun 30)

Watering: Water deeply and regularly; watch under hot sun.
Fertilization: Broad-spectrum feeding every 2–3 weeks.
Pruning: Consider partial defoliation if leaves are too large; only if tree is healthy.
Wiring: Minor wiring adjustments before cambium hardens.
Defoliation: Partial defoliation (2nd leafing) can refine foliage scale.
Pests Disease: Monitor aphids and scale; treat as needed.
Summer Protection: Provide light afternoon shade during heat waves.

Mid Summer (Jul 1 – Aug 10)

Watering: High-frequency watering; ensure no stress during heat.
Fertilization: Reduce nitrogen, focus on potassium if flower/fruit desired.
Pruning: Pinch new growth; wait until fall for structural changes.
Pests Disease: Spider mites can appear—use horticultural oil or insecticidal soap.
Summer Protection: Shield roots from extreme heat if uninsulated pot.

Late Summer (Aug 11 – Aug 31)

Watering: Maintain consistent moisture as growth begins to slow.
Fertilization: Back off nitrogen; apply phosphorus-rich formula.
