Should I Water My Cauliflower and Broccoli Plants Tonight Before I Cover Them As We Have Frost For Tonight

Question

I am concerned how to protect vegetables I have planted as we have frost & possible freeze coming tonight. I have head I should water them before I cover them and wondering if that is correct. Thank you for your help

Answer 1

Watering plants before a freeze helps them stay warm. Dry roots are more susceptible to frost. Broccoli can take a light freeze, but below 28 degrees F (-2 C) can cause damage.

Although a cool season vegetable, cauliflower is frost sensitive, too, and should be covered when frost is expected.
