Japanese Black Pine Near Ocean: Fertilize, Stop Annual Injections

Thinning Crown = Stress, Not Necessarily Death

Ocean‑side pine sparser on windward side. Annual bark‑beetle injections (if trunk‑injected) cause more harm than good.

Plan

1. Stop preventive injections; treat only if beetles detected nearby.
2. Fertilize now & spring: 1 lb 10‑10‑10 per inch DBH, watered in.
3. Monitor; increased root mass → denser foliage.
