Protecting Strawberries from Birds

Birds spot ripening strawberries before you do. The fix is simple: cover the plants as the fruit starts to colour up, using netting or a cage that is taut, secured and held clear of the berries. Done well, you keep the whole crop and keep wildlife safe too. Here is how, without the half-eaten berries.

Why birds love strawberries

Blackbirds, thrushes and pigeons are the usual culprits in UK gardens. They go for strawberries for the same reasons we do — sweet, soft, full of moisture — and they are brilliant at timing it. A berry that looks a few days off ripe to you is often pecked the morning it turns red.

The danger window is short but ruthless. Once the first fruit blushes pink, the clock starts. Leave a bed open for a week in June and a hungry blackbird can work through a row faster than you would believe. Container plants and hanging baskets are not immune either — see growing strawberries in pots for protecting those.

Netting done safely

Netting is the cheapest, most reliable answer — but only if you put it up properly. Loose netting draped straight over plants is the worst of both worlds: birds still reach the fruit through it, and they get tangled.

Get it right with three rules:

• Hold it clear of the fruit. Use a frame — bamboo canes with cane-toppers, hoops of alkathene pipe, or a simple timber box — so the net sits well above the berries. Birds can peck anything pressed against the mesh.
• Keep it taut. Slack netting sags onto plants and forms pockets a bird can wriggle into and not out of. Pull it tight over the frame.
• Secure every edge. Peg the net to the ground or weigh it down all the way round so there is no gap. A bird that gets in under a loose edge will panic and may not find its way out.

On mesh size, go small — around 2cm or less. Large-mesh netting (the loose plastic kind) is the worst offender for trapping birds and even hedgehogs by the legs at night. Fine mesh keeps birds out, and once fruit has set you no longer need pollinators reaching the flowers, so a tight weave is fine.

Fruit cages

If you grow a fair amount of soft fruit, a walk-in or low fruit cage is worth the outlay. It is a permanent frame clad in fine netting, with a door or liftable side, so you can get in to pick and weed without wrestling a sheet of mesh every time.

A cage suits a dedicated strawberry bed, or a mixed soft-fruit patch shared with raspberries and currants, which birds raid just as eagerly. Buy a kit or build your own from timber and netting. The key points are the same as for loose netting: taut mesh, no gaps at ground level, and a small enough weave to keep birds out while letting rain through.

The one trade-off is the roof. Snow or a heavy autumn leaf-fall can collapse a netted roof, so slacken or remove the top panel over winter once picking is done.

Other deterrents (and why some do not work)

You will see plenty of low-effort tricks suggested. Be honest about which actually earn their place:

• Shiny scarers — old CDs, foil strips, flash tape strung above the bed. These work for a week or two, then birds learn they are harmless and ignore them. Useful as a short-term stopgap, not a season-long fix.
• Fake hawks and scarecrows — same problem. Birds habituate fast unless you move them every few days, which nobody keeps up.
• Straw mulch — tucking straw under the plants is genuinely worth doing. It keeps berries clean and off the soil, which reduces grey mould, and a tidy straw layer is less of an invitation than mud-spattered fruit. It will not stop a determined blackbird on its own, though.
• Picking promptly — pick every ripe and nearly-ripe berry the moment it is ready, every day or two in the season. The less ripe fruit sitting out, the less reward for a passing bird.

None of these replaces a physical barrier. If you only do one thing, net properly. Everything else is a helpful extra. For a wider look at organic, low-fuss methods, see our guide to natural pest control.

Balancing with welcoming birds elsewhere

It feels contradictory to net birds out of the fruit while we encourage them everywhere else — but it is not. Blackbirds and thrushes earn their keep all year eating slugs, snails and grubs, so you want them in the garden, just not in the strawberries for a few weeks in June.

The trick is to give them their own draw away from the bed. A few bird feeders and a water source elsewhere keep birds busy and well fed, and a wildlife-friendly garden with cover and other food makes your fruit one option among many rather than the only buffet in town. Net for the short ripening window, then take the cover down and let the birds back to work clearing pests.

That is the whole job: cover at the right moment, do it safely, and welcome the birds the rest of the year. For everything else on growing the crop — from feeding to harvesting — head back to the main strawberry guide.
