End of Season Tips: Row Covers Protect Vegetable Plants from Light Frosts


Floating row covers, shade cloth, tarps, plastic , sheets and blankets are an easy way to protect crops from chilly nights and light frosts. Anchor  to the ground on each side and the ends; use garden staples, rocks, or boards to hold covers in place. Covering your plants will keep plants 2 to 5°F warmer than the air outside temperature—enough to protect plants from a light overnight frosts.

I am most concerned with keeping my tomatoes from freezing. If  light frost is predicted, I will cover with one of our many blue tarps and drag them off in the daytime so they don’t bake. The whole idea is to protect the tomatoes from frostbite. If that happens, instead of ripening, they will usually rot.

It ain’t pretty but it works!
