Master Gardener Field Guides

Practical guides built from WSU Extension's Pacific Northwest Gardener's Handbook. Each one starts from what you're seeing in the garden and ends with what to do, how much, when, and why. They're listed in handbook chapter order.

1. Ch. 3–5
   Soil amendments

   Fixing pH, organic matter, drainage, compaction, nutrients, salt, and contamination, with rates and a seasonal calendar.

2. Ch. 6
   Composting

   Choosing a method, troubleshooting piles, what's safe to add, worm bins, and using finished compost.

Guidance is for west of the Cascades unless noted. Purple-shaded entries are inferred from the handbook's rules rather than stated in it.
