To protect your plants that are susceptible to frost (less hardy), we recommend you cover your plants using a ‘garden fleece’.
Using a garden fleece can help provide protection in a number of ways: Frost and winter protection, wind resistant and adverse weather conditions such as hail, rain, heavy winds etc, raises temperatures and humidity under the cover, and protection from birds and insects.
To purchase a garden fleece, you could either search online or visit your local garden centre.
