Care Guide

Watering

Deep watering every 7–10 days during dry spells; reduce if natural rainfall is sufficient

Fertilization

Apply slow-release granular fertilizer once at bud break. Use balanced 10-10-10 fertilizer to support new growth; avoid high-nitrogen feeds in late summer

Banana peel compost tea:Compost banana peels for 2–3 weeks, steep in water, dilute 1:20 for root drench; avoid applying to dry soil
Pruning
  • Remove dead, diseased, or broken branches in late winter to improve airflow
  • Thin lower branches to form a clear trunk for landscape use
  • Avoid heavy pruning, as conifers do not regrow foliage from bare wood
