The typical bird netting is hardly visible. Put it up when the first berries start turning blue. If you get it up before any birds find the fruit they'll be much easier to fend off. Once they find the fruit they'll exploit the smallest hole.

My problem is the right side of my property is about 100' and we have about 15 plants in there.

That's a lot of netting. Obviously if thats the only way to go, I'll have to

Here in Madison, Wisconsin, I have not found it necessary to net blueberries. We have several shrubs, and harvest about 3 gallons of fruit every year. We do have some birds, and they do take some fruit, maybe 5% of the total harvest. We are in the city, and there is a wide variety of food for birds. I have heard comments from people living in rural areas who have to net their shrubs, or their cherry tree, because the critters will take 100% of the crop, if they can.

I have to net or otherwise my blueberry bushes would be bare. I'm located near a large section of woods, so this might contribute to the problem.

I just set up last night as my first real crop is coming in. Not sure how well it will work, but I'm using fish line strung taught randomly over the berries supported on garden posts. A local farmer told me he uses it for grapes and it works because the birds can't see it and their wings will clip it and will stay away.

Birds stayed away from the stuff around our house, I think because of all the traffic and cats.
