Garden netting is built by making a simple frame, stretching wildlife-safe mesh over it, and anchoring every edge tight to block pests.
Looking to keep birds off berries, stop caterpillars on brassicas, or give seedlings a calm microclimate? A well-built net keeps pests out while letting sun, air, and rain in. This guide shows you how to plan, size, and build a sturdy cover that works through the season and stores flat in the shed.
Netting Types And Best Uses
The right mesh depends on what you’re keeping out and how you’ll mount it. Use this quick reference to match net type to the job.
| Netting Type | Blocks | Typical Aperture / Notes |
|---|---|---|
| Insect-Proof Mesh | Butterflies, flea beetles, onion fly, aphids (many species) | Fine mesh that still passes rain and light; edges must be buried or clamped to stop gaps. See RHS insect-proof mesh guidance. |
| Floating Row Cover (Spun-bond) | Insects, wind scuffing, light frosts | Fabric rather than mesh; great early in the season on hoops; may hold extra warmth; lift for pollination. |
| Bird Netting (Framed) | Thrushes, pigeons, blackbirds | Use taut, wildlife-safe mesh on a frame; avoid loose drapes that can tangle birds; secure to the ground. |
| Wildlife-Safe Fruit-Tree Netting | Birds on fruit trees | In some regions, backyard fruit nets must be ≤5 mm mesh to prevent entanglement; see Victoria’s household netting rule. |
| Hardware Cloth / Rigid Mesh | Rodents, rabbits | Metal mesh on the lower skirt and raised beds; pair with finer top cover for insects. |
| Pond / Debris Netting | Leaves, large birds | Larger holes; not a pest mesh; use only where wildlife-safe and firmly tensioned. |
| Individual Mesh Bags | Birds and wasps on clusters or fruit | Slip over grape clusters or peaches; quick to fit; remove for harvest. |
How To Build Garden Netting Step-By-Step
This method gives you a tidy, strong cover you can scale from a single bed to a full fruit cage. Adjust dimensions to fit your plot.
Plan The Size And Height
Measure the bed and add clearance: at least 30 cm above the tallest crop so the mesh doesn’t rub leaves. Note access points for weeding and harvest. For rows, plan modular hoops; for blocks or berries, plan a cubic frame you can walk into.
Choose A Mesh That Fits The Pest
Match aperture to the target. Fine insect mesh keeps cabbage whites and many small flies out when fitted tight to the ground. Bird covers can use a slightly wider mesh on a rigid frame, but keep it taut to avoid snagging. Where rules apply on backyard fruit nets, pick wildlife-safe sizes that pass the finger test and meet local law.
For lab-tested insect exclusion figures, researchers found apple maggot stopped by ~2.3×2.3 mm squares and spotted wing drosophila by ~1.3×1.3 mm squares under trial conditions (mesh aperture experiments in the Journal of Pest Science). Fine mesh reduces entry, but you still need good sealing around edges.
Gather Materials
- Mesh or row cover (cut to bed size plus 30–40 cm margin all round)
- Frame parts: PVC or aluminum hoops; or timber uprights and rails; or metal conduit
- Ground pegs or staples; sandbags or timber battens for edges
- Clips or zip ties; screw-in eyelets; bungee loops for doors
- Optional: weed-suppressing edge boards, door kit, hinge and latch
Build A Low Hoop Tunnel (Veg Beds)
- Set hoops. Push 20 mm PVC or 10–12 mm metal conduit every 1–1.2 m along the bed. Aim for equal spacing and matching height.
- Brace. Run a ridge pole along the hoop tops with short screws or clips to stop wobble in wind.
- Drape mesh. Lay the mesh so it reaches the soil on both sides with spare to bury or batten.
- Seal edges. Bury the long sides 5–8 cm, or clamp to half-sunk boards as the RHS safety note recommends for neat, wildlife-safe edges.
- Close ends. Fold like gift-wrap at the hoops, then peg or batten tight. No gaps at corners.
- Access. Clip one long side instead of burying it so you can lift for weeding, then re-clip.
Build A Walk-In Fruit Cage (Beds Or Bushes)
- Mark posts. Set corners and intervals every 1.5–2 m. Drive posts 40–60 cm deep.
- Add rails. Screw top rails around the perimeter. Add mid-rails if your mesh is soft.
- Make a door. Frame a simple hinged panel. Fit a latch and a bungee loop to keep it closed.
- Stretch mesh. Start on the roof, then the sides. Pull tight in all directions; fix with staples and washers, or mesh clips on metal rails. Keep seams overlapped by 10–15 cm.
- Finish the skirt. Pin the bottom edge to the soil with ground staples every 30–50 cm, or screw to a timber kicker board. Add a rodent-proof metal skirt if needed.
Seal The Edges Right
Edge sealing makes or breaks the build. For insects, bury or clamp the full perimeter. For birds, a tight frame with a pinned skirt stops beaks probing under. Keep the mesh off leaves; contact points can rub and create entry holes.
Ventilation, Water, And Pollination
Fine mesh traps fewer pests, and it can also slow airflow a bit. Lift the cover during wet spells on soft fruit to reduce mold pressure. On pollinated crops, remove or roll back covers during flowering, or hand-pollinate under the net. Row covers that add warmth are best earlier or later in the season; switch to a true insect mesh once heat builds.
Choosing Mesh Sizes That Work
Mesh size is the balance between exclusion and plant comfort. Research trials point to sub-2.5 mm squares for many fruit pests, with smaller apertures needed for tiny flies. In practice, most veg plots do well with dedicated insect mesh for brassicas and alliums, and taut bird-safe covers for berries.
Wildlife-Safe Choices
Loose or snaggy nets can catch birds and small mammals. Keep mesh taut, off the foliage, and sealed. In some places, backyard fruit nets must have holes 5 mm or smaller; that rule exists to stop entanglement and is enforced with fines in some jurisdictions. If you can poke a finger through, it’s too open for those regions.
Frame Options
- PVC hoops: Fast, light, easy to cut; add a ridge pole for strength.
- Metal conduit: Strong and slim; bend with a hoop tool for perfect arcs.
- Timber: Classic look, easy to fix clips and doors; treat contact points.
- Aluminum kits: Bolts together; great for neat fruit cages and repeat moves.
Fasteners And Closures
- Spring clips or snap clamps on hoops
- Staples with penny washers on timber
- UV-stable zip ties on metal rails
- Bungee cord loops for doors and roll-ups
- Ground staples, timber battens, or sandbags for the skirt
How To Build Garden Netting For Different Beds
Brassicas (Cabbage, Kale, Broccoli)
Use fine insect mesh on hoops from transplant day. Bury the edges. Keep the net raised so leaves don’t touch it. Lift only to weed and water. This setup stops cabbage whites laying eggs and blocks many small pests near the soil line.
Alliums (Onions, Leeks)
Fine mesh or row cover on hoops right after planting. Seal edges to deter onion fly. Swap to a lighter mesh during dry spells for extra airflow.
Soft Fruit (Strawberries, Raspberries, Currants)
Build a low cage over beds or a walk-in cage for bushes. Use taut wildlife-safe net on a frame, with a pinned skirt and a simple door for picking. Remove or roll back covers during bloom if bees need access.
Fruit Trees
Wrap individual trees with wildlife-safe net or use mesh bags on clusters. Keep nets tight around a simple stake frame, not draped directly on branches. Where rules set maximum hole size for backyard nets, pick compliant mesh and fit it neatly.
Raised Beds Near Rodents
Line the base with hardware cloth before filling. Add an insect mesh lid on a light timber frame. This two-layer approach stops chewing from below and keeps flying pests above the canopy.
Mesh Size Picks For Common Problems
Use this field-ready cheat sheet to match pests to mesh. Sizes reflect trial data and horticulture practice; seal edges well for best results.
| Pest / Pressure | Recommended Aperture | Notes |
|---|---|---|
| White Butterfly On Brassicas | Fine insect mesh (sub-2 mm) | Use hoops; bury edges as advised by the RHS. |
| Spotted Wing Drosophila (Soft Fruit) | ~1.3×1.3 mm squares | Mesh aperture shown effective in research trials; keep covers on before ripening. |
| Apple Maggot | ~2.3×2.3 mm squares | Trialled apertures show strong exclusion; pair with tight edge sealing. |
| Birds On Berries | Taut, wildlife-safe frame cover | Stretched tight on a cage; pin the skirt; add a latched door for fast picking. |
| Rabbits / Rodents (Bed Base) | Hardware cloth ~6–12 mm | Under-bed layer; top cover can be a finer mesh for insects. |
| Backyard Fruit Trees | ≤5 mm mesh (where required) | Meets wildlife-safe rules in some regions; see the Vic guideline. |
| Wind Scuffing On Seedlings | Floating row cover | Light fabric; swap to insect mesh once heat arrives. |
Care, Use, And Storage
Daily Use
- Check tension after wind and rain. Re-clip sagging sections.
- Keep the skirt pinned or buried. Gaps invite pests.
- Open covers during bloom where pollination is needed.
Cleaning
Brush off leaves and seed fluff. Hose mud off the mesh. Dry before folding. Store flat or rolled, away from sharp tools and direct sun when not in use to keep the material in good shape.
Season Swaps
Start cool seasons with row cover on hoops to add warmth. Swap to insect mesh once daytime heat rises. On soft fruit, fit bird covers before color sets in, then remove right after harvest to give the plot more light.
Troubleshooting And Pro Tips
- Mesh rubs on leaves: Raise hoop height or add a centre ridge. Plants shouldn’t touch the net.
- Gaps at ends: Fold corners like wrapping paper, then pin. Add a short cross-batten if needed.
- Wind-lift: Use more staples or a heavier batten on the windward side. Sandbags also help.
- Condensation build-up: Roll a side up mid-morning, drop it again in the evening.
- Door flaps in gusts: Add a second latch point and a short bungee loop.
- Rodent nibble at the base: Add a 15–20 cm metal skirt buried at the edge.
Why This Build Works
A physical barrier stops damage without sprays, keeps foliage drier in heavy rains, and cuts wind stress on tender growth. The frame method also keeps mesh off flowers and fruit, so you get clean, quick harvests. Edge sealing is the small step that delivers the big win.
Quick Templates You Can Copy
1. 2×1 m Hoop Tunnel (Leafy Greens)
Four hoops at 1 m spacing, one ridge pole, 3×2.5 m insect mesh, 20 ground staples, 8 snap clamps. Bury both sides, clip one long edge for access.
2. 3×3 m Berry Cage
Posts at each corner plus mid-sides, top rails, one 70 cm door. One roof panel, four side panels of wildlife-safe net. Overlap seams and staple to rails with washers. Peg the skirt every 40 cm.
3. Single Apple Tree Wrap
Four stakes to make a square around the canopy dripline. Drape wildlife-safe net over; clip to a light timber ring near the base. Tie corners to stakes. Keep the mesh clear of branches and fruit.
Safety And Good Practice
Keep nets tight, neat, and checked. Loose nets can snag birds and small mammals. Many wildlife groups advise the “finger test” on backyard fruit nets: if a finger fits through, animals can get caught. A framed, taut cover avoids that risk and makes daily use easier.
Two reliable reference points: the RHS page on insect-proof mesh for setup tips and edge sealing, and the Agriculture Victoria rule on backyard fruit netting for wildlife-safe mesh sizes where such rules apply.
Costing And Cut List (Example Bed)
For a 2×4 m brassica bed with hoops:
- Mesh 3×5 m: one piece
- Hoops: five pieces
- Ridge pole: one piece, 4 m
- Clips: 12–16
- Ground staples: 30–40
- Timber battens (optional): two at 2 m
Shop once, then reuse. A quality mesh and solid clips last several seasons if stored dry and out of direct sun when not in use.
Wrap-Up: Build Once, Reuse Often
How to build garden netting comes down to a simple formula: a square frame or steady hoops, the right mesh for the pest, and no gaps. Fit it tight, keep it off leaves, and pin the skirt. With that, your plot stays productive and picking stays easy all season.
