How to Protect Your Plants with Fleece in Winter (Complete Guide for Gardeners)

Winter can be tough on your garden, especially if you grow tender perennials, young plants, or winter vegetables. One of the easiest and most effective ways to guard your plants against frost and cold winds is by using horticultural fleece. Lightweight, breathable, and budget-friendly, fleece can make the difference between plants that struggle and plants that burst back into life in spring.

In this guide, you’ll learn why plant fleece works, which plants need protection, and how to use fleece properlyduring the winter months.

What Is Horticultural Fleece?

Horticultural fleece is a soft, non-woven, breathable material used to shield plants from frost, cold winds, heavy rain, and even pests. It acts as a protective blanket, creating a stable microclimate around your plants without blocking essential light or moisture.

Key benefits of plant fleece:

  • Provides frost protection down to several degrees below zero

  • Lightweight and easy to position

  • Reusable with proper care

  • Safer for plants than plastic covers because it allows airflow

Why Plants Need Protection in Winter

Cold weather can freeze the water inside plant tissues, damaging leaves, stems, and sometimes entire plants. Frost-sensitive plants and young specimens are particularly at risk. Even hardy evergreens can be affected by harsh winter winds that strip moisture from their foliage.

By draping fleece over your plants, you help:

  • Reduce frost damage

  • Prevent windburn

  • Protect young roots from rapid freeze–thaw cycles

  • Maintain more stable temperatures around delicate plants

When Should You Use Fleece?

Fleece is especially useful during:

  • Frost warnings or unexpected cold snaps

  • Late autumn and early spring, when temperatures fluctuate

  • On tender plants such as dahlias, herbs, citrus, and young shrubs

  • Open or windy gardens where cold air exposure is higher

Top tip: Keep a roll of fleece handy—winter weather often changes fast!

How to Use Plant Fleece (Step-by-Step)

1. Pick the Right Weight

Fleece comes in different GSM (grams per square metre):

  • 17gsm – Light protection for mild frosts

  • 23–30gsm – Best for prolonged cold spells and wind protection

2. Wrap or Drape Gently

  • For individual plants, wrap the fleece loosely around the canopy and secure it near the base.

  • For vegetable beds, use hoops or stakes to create a small tunnel so the fleece doesn’t rest directly on delicate leaves.

3. Secure It Against Wind

Use pegs, garden clips, stones, or soil to hold the fleece in place. Winter winds can lift unsecured sheets easily.

4. Ventilate and Remove When Needed

On mild, sunny days, open or remove the fleece to prevent overheating or moisture buildup. Plants still need airflow, even in winter.

Which Plants Benefit Most from Fleece?

Here are some plants that thrive when given winter fleece protection:

  • Dahlias (especially crown protection)

  • Young citrus or fig trees

  • Herbs like rosemary and bay

  • Hydrangeas and other tender shrubs

  • Strawberries, lettuces, winter vegetables

  • Young fruit bushes and seedlings

Common Mistakes to Avoid

Avoid these pitfalls to get the best results:

✖ Wrapping too tightly – Can trap moisture and encourage mould.
✖ Using plastic sheeting – Lacks breathability and can scorch plants.
✖ Forgetting to secure the fleece – A single gust can undo your work.
✖ Keeping fleece on during warm spells – Plants can overheat quickly.

Final Thoughts

Plant fleece is an essential winter gardening tool—easy to use, inexpensive, and incredibly effective. By adding this simple layer of protection, you can safeguard your garden from frost, wind, and temperature swings, ensuring everything returns vibrant and healthy in spring.
