Best Frost Protection Fleece Jackets and Plant Covers UK

Why Frost Protection Matters Before the First Cold Snap

Most gardeners are caught out at least once by an early frost that blackens dahlia foliage or turns a prized tender plant to mush. In many parts of the UK the first frosts arrive in October or November, and even in mild areas a clear, still night can drop below freezing quickly. Frost damage happens when ice crystals form inside plant cells, and tender and evergreen plants, new growth and plants in pots are the most vulnerable.

Horticultural fleece is the simplest, cheapest way to buy plants a few degrees of protection. This guide looks at six options, from ready-made drawstring jackets for individual plants to rolls of fleece for covering beds. Fleece is not a miracle cure, and it will not save a plant from a prolonged hard freeze, but it will buy many plants enough warmth to get through a typical British frost.

The Products, One by One

1. Haxnicks Easy Fleece Jacket

Haxnicks is a well-known UK garden brand, and its Easy Fleece Jacket is built to slip over a plant and close with a drawstring so it stays put in wind. It is a reusable cover rather than a throwaway sheet, and the shaped design is much quicker to fit than draping loose fleece over each plant.

Pros: Shaped jacket with drawstring closure, reusable, trusted UK garden brand.

Cons: Single jackets cost more per plant than a roll of fleece, and one size will not suit every plant.

Who it suits: anyone protecting a few valued tender plants, shrubs or patio pots.

2. Green Thumbz Plant Fleece Frost Protection Jackets, 80cm x 100cm (2 Pack)

A two-pack of ready-made fleece jackets in an 80cm by 100cm size, which suits small shrubs, tender perennials and larger patio pots. It is among the cheapest ready-made options here, making it a sensible starting point if you only have a handful of plants to cover.

Pros: Low price for ready-made jackets, a useful mid-size for pots and small shrubs, quick to fit.

Cons: Only two jackets per pack, and the size is too small for large shrubs or tree ferns.

Who it suits: gardeners on a budget with a few medium-sized container plants.

3. Selections Fleece Plant Frost Protection Covers, 110cm x 90cm (Pack of 6)

Six jackets in one pack makes this the best-value option for people with lots of pots, such as a patio full of tender plants. The 110cm by 90cm size sits between the small and large options and works for most patio container plants.

Pros: Six covers per pack lowers the cost per plant, a practical mid-size, reusable if stored dry.

Cons: Thin fleece offers light protection, so for a hard freeze you may need to double up or move plants indoors.

Who it suits: anyone with a large collection of pots to protect.

4. DazSpirit Plant Fleece Frost Protection Covers, 120x180cm (2 Pack)

A larger pair of covers that suits taller shrubs, small trees and large pots. Larger sizes are useful because plants need to be fully covered right down to the base, with the cover tied or weighted so it does not blow away.

Pros: Large size covers taller plants, drawstring-style bags are straightforward to fit, sold as a pair.

Cons: Big covers can act like a sail in strong winds if not secured well, and sizing may be too big for small pots.

Who it suits: gardeners protecting larger shrubs, small ornamental trees and big containers.

5. DazSpirit Plant Fleece Frost Protection Covers, 200x240cm

The 200x240cm size is the largest in this list and is aimed at big shrubs, tree ferns, banana plants and other tall tender specimens. Large specimen plants are expensive to replace, so a big cover is a sensible insurance policy before the first hard frost.

Pros: Big enough for large tender plants, drawstring closure helps keep it in place, one cover protects a single large specimen.

Cons: Takes up more storage space and is overkill for small pots.

Who it suits: owners of tree ferns, large agapanthus or other big tender plants.

6. Green Thumbz Garden Fleece Frost Protection, 2m x 10m

A roll of horticultural fleece is the most flexible option because you can cut it to size and drape it over beds, rows of vegetables, young crops or irregularly shaped plants. Used with pegs or stones around the edges, it can protect a whole bed at a fraction of the price of individual jackets.

Pros: Cut to size for any shape of plant or bed, the cheapest per square metre, also useful for protecting winter veg and seedlings.

Cons: Needs pegging or weighting down, and it is less neat than a fitted jacket.

Who it suits: growers with raised beds, winter veg or a mix of plant shapes.

Buying Guide: How to Protect Plants from Frost

Jackets versus rolls

Jackets are quick, neat and reusable, and are ideal for individual plants and pots. A roll of fleece is cheaper and more flexible, and is the better choice for beds, rows of crops and awkward shapes.

Fleece thickness

Fleece is sold in different weights, usually measured in grams per square metre. Light fleece gives a few degrees of protection and is fine for early autumn, while heavier weights offer more but let in less light. Double layers can help on the coldest nights.

Cover plants properly

Fleece only works if it covers the whole plant and is secured at the base so warm air from the soil stays trapped. Cover plants in the late afternoon, before the temperature drops, and remove the covers on mild days so plants can breathe and get light.

Water, mulch and move pots

Moist soil holds heat better than dry soil, so water plants before a frost (but avoid waterlogging). A thick mulch of bark or compost insulates roots, and pots can be moved against a house wall, grouped together, or raised on pot feet to keep them off cold ground.

Know which plants need it

Tender perennials such as dahlias, cannas and salvias, citrus trees, tree ferns, young evergreens and anything recently planted are the usual candidates. Hardy native plants rarely need protection, so there is no need to wrap the entire garden.

Store covers dry

At the end of winter, shake covers out, let them dry fully, and store them somewhere clean and dry. Reusable fleece can last several seasons if it is looked after, which keeps the cost per year very low.

What to do if frost gets through

If a plant is blackened or limp after a frost, resist the urge to cut it back straight away. Damaged growth often protects the lower parts of the plant from further cold, and many perennials will shoot again from the base in spring. Wait until the weather warms up, then prune back to healthy green growth.

Using what you already have

Old bedsheets, hessian sacking and even bubble wrap (around pots rather than foliage) can help in an emergency, but they are bulkier, absorb water and are harder to fit than purpose-made fleece. A few pounds spent on proper covers will save you more in replacement plants than you might expect, and the fleece can be reused for several winters.

Our Recommendation

If you have a patio full of pots, the Selections six-pack is the best value, while the Haxnicks Easy Fleece Jacket is a good pick for a couple of prized specimens. For vegetable beds and borders, a roll of Green Thumbz fleece is the most economical way to cover a lot of ground, and the larger DazSpirit covers are the ones to buy for tall, tender plants.
