How To Protect Tomato Plants from Frost

Seasonal gardening requires checking the weather forecast every day if you live in an area where there are four different months.

Temperature fluctuations in late spring and early fall might cause stunted development, deformed blooms or fruit, or the premature loss of your frost-sensitive crops, depending on the severity.

In the same way that peppers and eggplant, two other popular summer vegetables, benefit most from ample light and warmth, tomatoes do, too.

Frozen tomatoes may inflict long-term damage to both young and elderly plants, even if the temperature doesn’t go below freezing.

Protecting Tomato Plants From Frost

Mature tomato plants, like young ones, need certain temperatures for fruit ripening, just as they do for vegetative growth, flowering, and fruit set.

For tomato fruits to turn from green to red, they need to be kept at a temperature of between 20°C and 25°C.

When the temperature drops below 50°F (10°C), part of the fruit’s ripening enzymes may be destroyed. The fewer frequently green tomatoes are exposed to these cold temperatures, the less likely they are to ever mature.

There is less of an influence on the taste, hardness, and storage life of tomatoes that are just beginning to turn red than there is on tomatoes that are still green.

1.Picking Tomatoes That Are Still Immature

If you want the juiciest and most flavorful tomatoes, let your tomatoes mature on the vine.

Protect your crop from frost by harvesting part of the fruit for ripening inside when temperatures begin to fall and intermittent frost warnings are in the forecast.

Reap tomatoes while they are just beginning to ripen. Red, slightly red, and very light green (nearly white) tomatoes may all be harvested, but medium green tomatoes should be left on the vine to ripen.

Cover the unripe tomatoes with newspaper and place them in a cardboard box. Tomatoes that are kept at 70 degrees Fahrenheit (21 degrees Celsius) should mature in approximately two weeks. To keep tabs on their development, a check-up with them every day.

Although your tomatoes may not become red, there are still many delectable dishes you can make with them.

2.To Protect Large Plants, Use Floating Row Covers

Despite their little size when they are first planted, tomato plants, particularly indeterminate varieties, may grow to enormous proportions by the time they are ready to harvest in the fall.

When temperatures fall below 50 degrees Fahrenheit (10 degrees Celsius), you’ll need to cover your tomato plants each night.

Drive pegs into the ground around your tomato plants before putting down a frost cover to form a tent-like structure. Add two feet to the height of your tallest plant to get the appropriate stake length. The stake should be able to be driven into the ground with at least one foot of clearance above the tallest plant.

Use a garden-specific frost cloth or drape blankets, bedsheets, and towels or burlap over the structure after you’ve built a frame. The textiles should be laid out such that they cover the soil line and extend down all sides.

Bricks or huge stones may be used to weigh down the fabric’s edges and corners to keep it in place. You may also use tent pegs or ground staples to keep it in place.

Let your tomato plants get some sunlight by removing their frost covers the following day.

3.Add A Tarp Made Of Plastic

The addition of a plastic sheet on top of the fabric components will help to keep the wearer’s body temperature at a comfortable level.

Make certain that no leaves of the plants are touched by the plastic covering. Duringfreezing conditions, any plastic that touches plant tissue will freeze.

4.Adding A Space Blanket

Using space blankets as frost protection in the garden may increase your protection even more.

90 percent of the heat will be reflected in the plants using these mylar thermal blankets. Using a plastic tarp as a base, place a glossy piece of cloth on top.

5.Use Water Jugs To Provide Heat

Plain old H2O may hold on to heat and release it at night when the plants need the warmth, just as with Wall O Water

One-gallon containers should be filled with water, and the lids should be screwed on. A sunny place adjacent to the tomato plants is ideal for placing these water containers.

Your frost coverings should be used at night to protect your plants from the cold. During the evening, the water jugs will gradually warm up.

Make sure the jugs are covered the following day so they can soak up the sun’s rays for an additional day.

6.Make Your Home Festive By Hanging Lights

Strings of bright Christmas lights may also be used as an additional source of heat. It’s best to stick with incandescent bulbs if you want the maximum heat. With these bulbs, you’ll feel the warmth and see temperatures rise 2 to 10 degrees Fahrenheit (1 to 7 degrees Celsius) beneath the blanket.

Clip the lights to your tomato plant supports or set them on the ground around your plants. Just make sure they don’t come into contact with the plants or the frost covers.

7.Water In The Evening

Water your tomato plants well before the impending frost. Warmth is radiated upwards from surrounding plants when the soil is moist.

To allow the soil to warm up before dusk, water in the late afternoon when temperatures are at their highest.

8.Apply A Thick Coat Of Mulch On The Surface

Adding a thick layer of mulch around plants also serves as an insulator, reducing the risk of disease. Apply 6 inches of mulch to your tomato crop ahead of a cold spell.

Each plant should have about an inch of dirt visible around its center stem. In this way, the plant will be able to take in the heat from the soil as it grows.

When the weather starts to warm up again, you may start to remove some of the mulch.

● Snowstorm preparations

Setting out frost blankets and cloches each evening and dragging them in each morning might be a hassle when you live in a frosty area.

You may alleviate some of the stress of losing your favorite plants by preparing for future frosts.

9.Create A Garden Greenhouse

Protect and extend your warm-season crop growing season with a permanent greenhouse.

Greenhouses may be made in any form or size since they are just a frame encased in glass or plastic.


To protect your tomato plants from frost, you’ll need two things: tomato cages (wood or metal) or robust garden poles, and bubble wrap. Your construction will be made out of tomato cages or garden pegs, which you will cover in bubble wrap to safeguard your plants.
