Erroll, of WashingtonWineMaker.com stopped by and recommended I put bird netting over the grapes. I had thought about putting up something to keep the deer out, but forgot about the birds.
I attached some boards to the top of the posts, then attached 1 inch deer fencing. The fencing is 7 feet wide and comes on 100 foot rolls. It took two pieces to fully cover the grapes. One on each side.
This reminds me of picking cherries earlier this summer. The Blue Jays were screeching at us and trying to chase us off. Blue Jays are very territorial and apparently have no idea just how small they really are.
Now that the grapes are covered, I can sleep easier. Thanks for the reminder Erroll. Now if I could find netting to keep out Japanese beetles…
