Gardening Question of the Week:
Do Row Covers Protect Plants from Frost Damage?

By , About.com Guide   September 1, 2010

Follow me on:

Frost happens, even when you least expect it. Sometimes it's a relief, to finally be able to put your garden to bed. Sometimes it's a freak occurrence and you'd like to keep your plants going a little longer, or you're panicking because you just put them out and wish you hadn't.

Row covers are a quick and easy way to extend your growing season by a couple of weeks. Row Covers, sometimes referred to as Floating Row Covers, are lightweight spun bonded synthetic fabrics that are laid over plants for protection against pests and temperatures. They are light enough to rest on the plants and allow light, water and even fertilizer to get through. In general, they add about 2-4 degrees F. protection. Depending of the weight of the fabric, you could keep your plants growing even when nighttime temps dip down into the mid-20s.
