The best way to ensure garden plants are protected from harsh conditions is invest in a frost blanket. They are lightweight, easy-to-use sheets of plastic material.

There are a few simple ways to protect your plants from frost.

How Does A Frost Blanket Work?

A frost blanket works in a very simple fashion to protect plants from frost. It basically just traps the heat stored in the soil to keep your plants warm. This means the ground and plants will not freeze during a cold spell.

Frost blankets are made from a slightly see-through plastic material. This means that light and moisture can get into your plants. This allows them to be fed properly, even under the blanket, so that they don’t die of dehydration or lack of sunlight.

How To Use A Frost Blanket To Protect Plants From Frost

Now you know what a frost blanket is and how it works, it’s important to use it properly. Otherwise, it will be no good to protect plants from frost in your garden. The type of weather you are expecting will impact how you use this tool. If it gets frosty at night, then this is when it needs to be applied. Nighttime is usually the coldest, so this is likely. However, sometimes it is also very cold during the day, so you can also use a frost blanket then.

Remember to remove the frost blanket in the morning after a spell of cold weather overnight, provided it is warmer in the day. This will allow the plants to air out and get more sunlight and moisture to stop any damage from condensation or lack of nutrients.

When applying the frost blanket, the fabric should not touch the plant. You can get some wire tomato caging or pegs and soil pins to prop up the sheet above the plants, covering but not touching them. Make sure the sheet is tucked in at ground level so there are limited gaps. This will keep the moisture and heat in.


Using a frost blanket to protect plants from frost is very simple. Time and money spent are minimal. This will save your greenery from freezing during a particularly cold spell of weather. Make sure to prepare thoroughly for Winter this year by protecting your plants if you want your garden to stay looking green and beautiful next Spring!
