COLUMBIA, S.C. — Frost can be both a blessing and a curse for gardeners. While it can cause trouble for many vegetables, some crops will thrive and even taste better.
Root crops, like beets and turnips, produce more sugar when the soil temperature dips below 40 degrees. As a natural process, frost helps convert starches into sugars, providing extra sweetness.
Ice formation within plants, however, can result in dehydration and other risks.
Tomatoes and peppers will likely die from a light frost of 32 degrees or colder because tender plants are not well adapted.
An easy way to protect your garden is to purchase row covers or even bed sheets for protection. Be sure not to use plastic and loosely drape over your plants. Check that your cover is secured to the ground.
