What to Consider When Protecting Plants From Frost

Know Your Area's Frost Dates​: Although Mother Nature can change her mind when cold weather strikes, it's best to know your area's first and last frost date averages so you can be prepared. Although expected temperatures and dates for cold weather give only a general guide to past years, they'll give you a pretty good idea of expected cold snaps and the temperatures involved. If growing plants from seed, the seed packet gives an idea of when it's best to plant to avoid damage from too cold temperatures. For example, the seed packet might suggest planting two weeks after your area's last cold snap.

Pay Attention to Your Weather Forecast​: Pay attention to your local weather forecast predicting a sudden temperature change to colder conditions. Be prepared by having all your frost protection supplies on hand. You'll then be ready to protect your plants before the colder temperatures arrive. Cold temperatures can become more destructive on calm and clear nights with minimum cloud cover. In addition, colder temperatures and frost congregate in low-lying areas of the landscape called frost pockets.

Planting your garden or frost-sensitive plants in higher areas of your landscape will help protect them from sudden cold temperature changes. Even planting in raised beds elevates your plants and helps protect them from frost damage.

Grow Plants Hardy to Your Region​: If planting directly into your landscape and not in pots, only grow plants that are hardy growing in your particular USDA hardiness zones, unless you want to treat them as annuals. Plants hardy in your USDA zones typically withstand your specific region's average high and low temperatures and only require frost protection when temperatures dip below these averages. If you desire to grow plants sensitive to cold temperatures, it's best to grow them in pots so you can bring them indoors to a protected location during a cold snap.

Size of Plants and Garden​: When selecting products to protect your plants from frost or freezing weather, consider the size of your garden and the plants requiring protection. This will give you a good idea of what type of frost protection will work well for your situation and garden. For example, if you're protecting a larger vegetable garden, you'll need something that covers the entire area. However, if you are only protecting several plants, an individual covering will work. Be sure to select a frost protection product that covers the plant fully and is large enough that it doesn't squish the plant or damage it.

Protection Rating​: Frost protection fabrics have different weights and thicknesses that affect the degree of temperatures they offer protection from. Thicker and heavier materials offer protection from colder temperatures than thinner types. The available frost protection fabrics come in weights from 0.05 ounces to 3.5 ounces, with 3-ounce fabrics offering protection for temperature drops into the teens and 0.05-ounce fabrics rated usually to temperatures around 35 degrees Fahrenheit.
