Garden netting is one of the most underrated tools in the British vegetable grower's arsenal. The UK has a specific and persistent set of garden pests that netting addresses directly: the cabbage white butterfly (Pieris brassicae) strips British brassicas from midsummer onwards, the wood pigeon causes widespread destruction to brassica crops in rural and suburban gardens alike, and slugs — thriving in our damp climate — devastate unprotected seedlings overnight. For each of these threats, the right type of netting or fleece provides a simple, chemical-free solution that works with the weather rather than against it.
Bird netting requires particular care in the UK. Wide-mesh netting left to sag is the type most likely to trap and injure garden birds such as blackbirds, robins, and sparrows. A smaller aperture, netting pulled taut over hoops or a frame rather than draped loosely, and edges pegged into the soil all reduce that risk. If you use bird netting over fruit bushes, soft fruit, or vegetable beds, check the mesh size before buying and inspect the netting regularly for birds that may have become trapped.
For brassica protection against cabbage white butterflies, fine insect mesh (0.8mm or finer) is the gold standard. It completely excludes the butterfly from laying eggs on cabbage, kale, broccoli, and Brussels sprouts — the main UK brassica crops — without blocking light or rain. Frost fleece performs a different but equally important role in the British growing year: protecting seedlings from late frosts in April and May, and extending growing into October. Choosing between these product types depends on your specific UK growing challenges rather than a single catch-all product.
Buying guide
What to look for in Garden Netting
1Use fine insect mesh (0.8mm or finer) for brassica crops — it completely excludes cabbage white butterflies without blocking rain or significant light, and is far more effective than netting with larger apertures.
2For bird netting, choose the smallest mesh that still does the job and fit it taut over a frame — loose, wide-mesh netting is what traps and injures garden birds, and wild birds are protected under the Wildlife and Countryside Act 1981.
3Choose UV-stabilised netting for UK outdoor use — non-UV-stabilised products degrade rapidly in British summer sunlight and become brittle within a single season.
4Use frost fleece (not netting) for late UK spring frost protection — a 17g/m² or 30g/m² fleece provides meaningful frost protection while allowing some light and air exchange.
5Slug netting or copper tape around raised beds is worth adding alongside overhead bird and insect netting — slugs are among the most damaging UK garden pests and are not addressed by overhead protection alone.
Our process
How we choose our picks
We don’t lab-test products ourselves. Instead we synthesise the strongest independent evidence — current Amazon UK listings, verified-buyer feedback, published specs and UK pricing — into clear, honest recommendations. We earn a commission if you buy through our links, but that never changes which products we rank.
Current UK availability
We only shortlist products actively listed and in stock on Amazon UK, checked against live catalogue data — not last year’s models.
Publicly visible buyer feedback
We look at how each product is received by UK shoppers — its overall rating standing and the praise or complaints that recur in public reviews — rather than relying on a single reviewer’s opinion.
Published specs & value
We compare manufacturer specifications, typical UK price bands, warranty and running costs so each pick is right for a real budget and use-case.
UK-specific fit
We factor in UK voltage, plug/fitting standards, CE/UKCA marking and Consumer Rights Act cover — details that generic global lists miss.

Where the Bosmere fleece protects growing seedlings, the Hozelock Ultrafleece is designed for protecting established tender plants — tree ferns, agapanthus, bananas, and tender shrubs that need wrapping to get through a UK winter.
Type
Heavy horticultural fleece
Weight
30g/m²
Dimensions
Various (5m roll)
Material
Heavy-duty spunbonded polypropylene
Use
Frost protection, overwintering tender plants
What we like
+30g/m² heavy fleece provides up to 4°C frost protection — suits harsh UK winters
+Thick enough to protect tender perennials and tree ferns from UK ground frost
+More durable than the standard 17g fleece above — reusable for multiple seasons
Worth noting
–Too heavy and light-blocking for use over actively growing seedlings
–Heavier grade than you need if you are only covering seedlings through a typical -1°C to -3°C UK spring frost
Tierra Garden's 20mm netting is the sensible choice for UK fruit growers who want bird protection without the wide, sagging mesh that causes entanglement. One sheet covers a full fruit cage, and the UV-stabilised polypropylene should hold up across several British growing seasons.
Type
Bird exclusion netting
Aperture
20mm
Dimensions
4m x 10m
Material
UV-stabilised polypropylene
Use
Fruit cage and soft fruit protection from birds
What we like
+20mm aperture is small enough to keep fruit-raiding birds off the crop without the wide gaps that cause entanglement
+Large 4m x 10m sheet covers full fruit cage or soft fruit row
+UV-stabilised to resist degradation through British summer sunlight
+Neutral colour is less visually intrusive in the UK garden
Worth noting
–Must still be checked regularly — 20mm mesh can occasionally trap small birds
–Requires cane or frame support to avoid sagging onto fruit

Editor's Note
UK brassica growers should install insect mesh over crops from planting out in May — do not wait until you see cabbage white eggs or caterpillars, as a single unnoticed batch of eggs can devastate a kale or broccoli plant within a week. The most practical approach is to build a simple hoop tunnel using flexible conduit or proprietary hoop kits (widely available from Harrod Horticultural and similar UK suppliers), then drape mesh over the top and peg the edges into the soil to exclude both butterflies and wood pigeons simultaneously. Replace bird netting every two to three seasons — UV degradation makes it brittle and increases the risk of birds becoming entangled as the mesh loses its original tension.
Our Take
Fine insect mesh is the most effective chemical-free intervention for UK brassica growing: once it is over the crop it blocks cabbage white butterflies with no ongoing effort. Buy more than you think you need — a 50m roll covers multiple beds and, if it is UV-stabilised and stored dry, lasts several seasons.
Questions & answers
Frequently asked questions
What mesh size is safe for bird netting in the UK?
There is no single legal figure, but the safest garden bird netting has a small aperture, is pulled taut over a frame, and is pegged down at the edges. Wide-mesh netting left to sag is the type that traps blackbirds, sparrows, and robins. Wild birds are protected under the Wildlife and Countryside Act 1981, so inspect netting after fitting and regularly afterwards for trapped birds, and take it down once the crop no longer needs it.
What is the best way to protect brassicas from cabbage white butterflies in the UK?
Fine insect mesh with an aperture of 0.8mm or smaller is the most effective method. It physically excludes the cabbage white butterfly from laying eggs on cabbage, kale, broccoli, cauliflower, and Brussels sprouts. Drape it over hoops above the crop and secure the edges with pegs or soil to prevent butterflies from finding gaps underneath.
How much frost protection does horticultural fleece provide?
A standard 17g/m² frost fleece provides approximately 1–2°C of frost protection. A heavier 30g/m² fleece provides up to 4°C of protection. For most UK spring frosts (typically -1°C to -3°C), a 17g fleece is sufficient for seedling protection. For protecting tender established plants through a UK winter, the heavier 30g grade is recommended.
Do slugs get under garden netting in the UK?
Yes. Overhead insect or bird netting does not protect against slugs, which travel along the ground. To protect seedlings from slugs — one of the most damaging UK garden pests — use copper tape around raised bed edges, beer traps set at ground level, or wildlife-friendly slug pellets (ferric phosphate-based) in addition to overhead netting.
Is garden netting reusable in the UK?
UV-stabilised netting and fleece can be reused for multiple seasons if stored dry and out of direct light during winter. Non-UV-stabilised products (often sold unbranded) typically degrade after one UK summer season and become brittle. Buy UV-stabilised products and store them folded in a shed or garage between uses.
