Gardeners are being urged to take immediate action to protect their plants from winter frost, which can cause leaf scorch and browning, weakening plants and reducing growth and blooms in the following year.
Hannah Rowson, assistant garden centre manager at bulb specialists J.Parker's, advises using protective coverings such as horticultural fleece, hessian, or polystyrene sheets. These breathable, insulating materials help plants retain moisture without becoming waterlogged, and wrapping stems and branches securely can prevent frost cracking, especially for sensitive shrubs or young trees.
To keep soil warm and protect roots, Rowson recommends a double mulching technique: start with a base layer of straw or shredded bark, then add a loose compost or leaf mould layer on top. This insulates roots and stabilises soil temperature through winter.
For tender perennials or winter vegetables, cloches or cold frames are suggested. These mini greenhouses trap warmth, prevent excessive moisture, and shield plants from cold winds. Rowson warns that covers should be removed during milder winter days to prevent rot, then replaced when temperatures drop again.
As the weather warms, gradually remove coverings to help plants adapt. Starting with a few hours each day allows plants to get used to sunlight and warmth, reducing shock and promoting healthy growth.
