Crows have been constantly digging up my onions in a no dig bed. we have dozen of crows nearby. We have a 5 acre orchard in kent and are experimenting into no dig on our land.
Any advice?
It’s the same here, there’s a rookery next door. I’ve found that netting, supported by sticks/posts around the bed, stops them. Once the onions & garlic have been grown on for a while & have a good root system the birds no longer uproot them. Make sure they can’t get under the netting.
