Windbreaks & Shelter

Technique

Wind can shorten the UK growing season as much as cold, stripping warmth from leaves and soil, drying plants and damaging blossom. Creating shelter makes gardens and allotments feel warmer without artificial heat. A well-planned windbreak reduces exposure while still allowing some air to pass through, helping crops establish and crop more reliably.

How it works

A porous barrier slows wind over a broad area rather than forcing it up and over the top, where it can tumble down in damaging gusts. Reduced wind chill helps soil warm, lowers water loss and protects stems, flowers and fruit. Hedges, woven fencing and purpose-made netting can all create useful shelter. Complete solid barriers may cause turbulence, so they need careful siting.

Best for

Shelter is valuable for all exposed sites, especially coastal gardens, hill plots and open allotments. It benefits flowering fruit trees, peas, beans, brassicas, salads and tender vegetables such as courgettes, tomatoes and peppers. Use it where blossom is regularly damaged, seedlings lean or dry out, or a polytunnel and mini-greenhouse face persistent gusts.

How to use it

Observe prevailing winds through the seasons, then place a permeable windbreak across their path without shading key growing areas. Establish a mixed hedge where space permits, or install strong, well-anchored windbreak netting for quicker results. Leave access routes for wheelbarrows and avoid trapping cold air in frost pockets. Protect young plants with temporary fleece or cloches while longer-term shelter establishes. Check posts, ties and netting after storms, and keep surrounding soil watered while new hedging roots in.

Tips

Aim for filtered shelter rather than a completely solid screen. Position tender crops on the leeward side, but not so close that they receive no light or airflow. Combine wind protection with mulch and watering, as sheltered areas can still dry out. Keep hedges trimmed to prevent excessive shade and competition.
