I have no idea why I never thought of this, or not ever heard of this, but somehow I learned about it the other day.
They are fruit bags you put over your tree fruit, to keep birds and bugs off of them. I just covered a lot of apples, but may get the ladder out there and get more covered up. I am also hanging garlic around the bottom of the branches to keep deer and raccoons out of trees.
I'll be sure to let you know if they work. They even have bags for your grapes. I may have to put our grapes in next year. The last ones were ruined, and I can't remember why. Maybe a drought and we just couldn't keep up? Anyway, I learned something new.
