I have a question about spraying the apples.

What do you do when the trees bloom at different times? Some of my trees are finished and have fruit set. Some of the trees are in full bloom.

Do I spray the trees now that are finished blooming? Thus having different trees on a different time schedule and perhaps endangering the bees? Do I wait until everyone is finished blooming?

I've only had worms in the apples, but just heard that coddling moth will strike Asian pears. I haven't had any problems with the Asian pears, but will the CM move over to those trees if they find that the apples have been sprayed?

I don't like to spray just to be spraying, so I plan to only spray the apples, since none of the other fruit has ever had bugs.
