I didn’t bag last year, not ambitious enough. This year I’m trying the nylon footies from Home Orchard Society. It takes some practice to tie them on. For me, the sandwich bags didn’t work well, seemed to cause more damage than they prevented. Others on this thread have better ideas, but I think it depends on each of our climates. I tied footies on about 3 dozen apples, and have about double that number now without any.
I don’t know if they will be needed this year. I have ducks penned under most of my apple trees. They have been busy sticking their bills into the ground for mugs, larvae, worms, and other cool stuff, which I eat second had via duck eggs. Maybe the ducks will do better than the bags.
