Episode 7: Pests, disease & plant health
“Why is that pest there?”
Immunity as an outcome of plant health, and what the pest is trying to tell you before you reach for the spray.

The big idea
Ask why first.
The usual answer is what to spray and when. Steve’s first question is why the pest turned up at all.

A pest is a message
Pests and disease aren’t just bad luck. They turn up most on plants that are out of balance, so a pest is often telling you something about the plant’s health before it tells you what to spray.
This episode treats immunity as an outcome of plant health: health first, and protection follows.
