Lesson 10 — Seasonal IPM Calendar (PNW)

Goal: anticipate problems rather than react.

Seasonal patterns (general)

• Spring: aphids, soft growth, leaf spots with rain
• Summer: mites, thrips, heat stress, irrigation issues
• Fall: Botrytis risk rises, crowding and wet nights
• Winter: root rot risk if media stays wet and cold

Do this

1. Create a 1-page calendar with your top 5 crops and expected issues by month.
2. Add your “prevention actions” (spacing change, airflow, sanitation push).
