Composting Squash Plants with Caterpillar Damage: Safe Practices

A gardener using organic spray for caterpillars on squash asks if damaged plant parts can go into the compost bin without causing next year's infestation.

Expert Answer: Yes, composting will kill any organisms on the cut pieces. Ensure the pile heats up by adding nitrogen (grass clippings, fertilizer, or green matter) and turning it weekly. Once fully composted, it poses no risk to next year's garden.
