How To Cover Plants Frost

How to Cover Plants Frost Frost can be a real problem for gardeners, causing damage to plants and potentially killing them off completely. Luckily, there are ways to protect your plants from frost, and in this article, we’ll go through some of the best methods for doing so.

Why is Frost a Problem for Plants?

Frost can cause damage to plants in a number of ways. Firstly, it can freeze the water inside the plant, causing the cells to burst and leading to irreversible damage. Secondly, frost can damage the outer layer of the plant, causing it to become discoloured and potentially leading to disease. Finally, frost can cause the plant to go into shock, which can stunt its growth and leave it vulnerable to other problems.

How to Cover Plants Frost

There are a number of ways to protect your plants from frost, including:

1. Bring Potted Plants Indoors

If you have potted plants that are susceptible to frost damage, the easiest way to protect them is to bring them indoors. This will keep them warm and dry, and ensure that they don’t freeze.

2. Cover Plants with Blankets or Sheets

Another option is to cover your plants with blankets or sheets. Make sure that the cover reaches all the way to the ground, and secure it with rocks or bricks to prevent it from blowing away.

3. Use Frost Covers

Frost covers are specially designed to protect plants from frost damage. They are made from lightweight, breathable fabric, and can be placed directly over the plant. They allow air and light to pass through, while still providing protection from frost.

4. Mulch Around Plants

Mulching around your plants can help to protect them from frost. The mulch acts as an insulating layer, keeping the soil and roots warm even when the air temperature drops.

5. Water Plants Before a Frost

Watering your plants before a frost can help to protect them. The water will help to insulate the plant, and also release heat as it freezes, helping to keep the plant warm.
