Can Blackberry Plants Survive Frost?

Blackberry plants are a popular fruit-bearing plant that is grown in many parts of the world. These plants can be grown in a variety of climates and soil conditions, making them a versatile crop.

However, frost can be a significant challenge for blackberry growers, especially in areas where temperatures drop significantly during the winter months. In this article, we will discuss how blackberry plants are affected by frost, and what growers can do to protect them.

What is Frost?

Before discussing the effects of frost on blackberry plants, it is essential to understand what frost is. Frost occurs when the temperature drops below freezing, causing the moisture in the air to freeze and form ice crystals. These ice crystals can form on plants and other surfaces, causing damage or death to the affected area.

How Does Frost Affect Blackberry Plants?

Blackberry plants can be damaged by frost, affecting the fruit, new growth, and roots. Growers can protect their plants by covering them, watering them before a frost, and pruning them. Blackberry plants can survive freezing temperatures, but prolonged exposure can damage or kill the plant.

Frost can affect blackberry plants in several ways, including:

1. Damage to Fruit

If blackberry plants are exposed to frost during the flowering or fruiting stage, it can damage the fruit. Frost can cause the fruit to become discolored, shriveled, and inedible, reducing the overall yield.

2. Damage to New Growth

Frost can also damage the new growth of blackberry plants, affecting the plant’s overall health and vigor. If the frost is severe, it can cause the new growth to die back, reducing the plant’s productivity.

3. Damage to the Roots

Frost can also damage the roots of blackberry plants, affecting the plant’s ability to take up water and nutrients from the soil. If the roots are damaged, the plant may become stressed, reducing its overall yield and vigor.

How to Protect Blackberry Plants from Frost

Protecting blackberry plants from frost is essential for ensuring a healthy crop. Here are some steps that growers can take to protect their plants:

1. Cover Plants

One of the most effective ways to protect blackberry plants from frost is to cover them. Growers can use blankets, tarps, or other materials to cover the plants when frost is predicted. The cover should be removed during the day to allow the plant to receive sunlight and warmth.

2. Water Plants

Watering blackberry plants before a frost can also help protect them. Watering the plants will help insulate them and prevent the frost from damaging the roots and new growth.

3. Prune Plants

Pruning blackberry plants can also help protect them from frost. By removing any damaged or dead wood, growers can reduce the risk of frost damage and improve the overall health of the plant.


Frost can be a significant challenge for blackberry growers, but with the right precautions, it is possible to protect the plants and ensure a healthy crop.

Covering the plants, watering them before a frost, and pruning them are all effective ways to protect blackberry plants from this potentially harmful weather condition. By following these steps, growers can enjoy a healthy and productive crop of delicious blackberries.
