There are two spray schedules on the site- Alan’s synthetic schedule and Scott’s low impact semi-organic schedule. I have attached links to both. I think both are worth reading through.
Myself I spray a synthetic insecticide once or twice and then bag. Bagging is easier than you think especially when comparing to spraying. With bagging you bag once and you’re done. With spraying the process has to be repeated multiple times. When I bag I wear a t-shirt and shorts. When spraying I wear long pants, long-sleeved shirt, a hat, rubber gloves and eye protection. It can get uncomfortably hot when spraying in hot humid weather. I can also bag when it’s windy and I can’t spray.
So bagging has it’s advantages. It works best on small trees or at least short ones since ladder work is minimized. I bag about a 100 a year right now. I think some people on the site bag in the 400-500 range but numbers above this are probably not practical for most people. Apples are bagged when dime size or bigger but insects sometimes attack the fruit before it reaches this size which is why I spray before bagging. So you might give bagging a try.
