30gsm Non-Woven Frost Protection Fleece 1.1m x 5m | Winter Garden Cover & Plant Protection Fabric

Frost protection fleece is one of those things you reach for more often than you expect; a roll kept in the shed will earn its place from the first cold snap of autumn through to the last frost of spring. This listing is for our 30gsm non-woven fleece, cut to 1.1 metres x 5 metres, a weight suited to late autumn and winter use as well as the shoulder months of early spring.

The fleece works by trapping warmth and humidity close to the plant without sealing it in entirely. Light, rainwater and air pass through the fabric, so covered plants continue to photosynthesise and take up water without the risk of the airless, damp conditions that encourage mould. That balance is what separates a proper horticultural fleece from a makeshift covering; the plants beneath it are sheltered, not smothered.

At 30gsm, this is a mid-weight fleece, heavier than the 17gsm grade used for light spring protection and better suited to harder frosts, hail and persistent cold winds. It will also bring germination on a little earlier in the season, as the raised temperature beneath the fabric gives seeds and young plants a more settled start than open ground can offer in February or March.

Lay it loosely over plants or beds and anchor the edges with soil, stones or pegs; the fabric needs to sit without pulling tight, so that plants have room to push upward as they grow. Stored dry and folded at the end of the season, a sheet of this weight will last several years.

Put it down before the first forecast frost rather than after; recovery takes longer than prevention. Used from October through to March, a single sheet will cover a raised bed of brassicas, protect a row of overwintering broad beans, or keep a tender shrub through a cold spell without any further intervention.
