Shield small plants
If you know bad weather is around the corner and want to protect your small plants, cover them with a plastic bag, cardboard box, upside-down flowerpot, or even a plastic laundry basket to protect them.

Or, drape a thick blanket or quilt over plants before nightfall to trap soil heat and protect plants from light frost.
