Vegetable Gardening : How to Protect Outdoor Plants From Frost

Basil, peppers, tomatoes, cucumbers, eggplants, and summer squash.

You can use row cover or Reemay, which is a thin sheet that lets light and rain through while keeping the plants warm.

Row cover acts like tucking the plants in for the night, providing about three degrees of frost protection. It can withstand temperatures down to around 29 degrees Fahrenheit.

No, sometimes it is more cost-effective to use a sprinkler to prevent damage from light frost.

The moving water from the sprinkler has a hard time freezing, which prevents the leaves of the plants from freezing.

Besides row cover and sprinklers, there may be other methods such as using frost blankets, creating a makeshift greenhouse, or bringing potted plants indoors.
