Frequently Asked Questions

How do I protect Broccoli from cabbage white caterpillars?

Broccoli needs protection from cabbage white caterpillars, a common pest — floating row covers over young plants and regular inspection for eggs on leaf undersides are the most effective preventive steps.

What temperature does Broccoli need to head up properly?

It tolerates light frost and does best in cooler conditions around 45–65°F — heat stress can cause the heads to bolt or turn loose and bitter before harvest.
