Both are mid season bloomers, so I'd guess they'd do well. Here is a link that might be useful: Good Explaination of Apple Pollination

I knew what it was, but not having had to deal with them didn't know much about it. I read a bit online and as fruitnut said, they are indeed difficult to control. There is one insecticide acephate (Orthene), that kills them. I understand what fruitnut is saying about not doing anything, but if it were me...I'd do something. I couldn't leave that alone. I did read that insecticidal soap or dormant oil spray may do the job. Normally, I'm not much for soaps and the like, but in this case I can see where that might just be the ticket. Apparently their waxy bodies protects them quite well. This may sound silly, but I wonder if you mixed one two of those small 50 cent bottles of Elmer's glue into a quart or so of warm water then added a tablespoon of sulfur if that might do the trick. Maybe forget the sulfur, I just kinda view it as a cure-all and I know it's deadly to aphids. I think the glue would bind them because of their feathery bodies. The glue should be harmless, if not beneficial to the tree. Anyway, if it sounds goofy forget it...just me sittin' here thinkin'.

Drip systems are not designed for tree watering. If the root area is dry, then it's simply not getting enough water would be my guess. One does not water every "X" days.....one waters when water is needed and then deeply. That's the key word.

Is it in a pot? If so, leave it for now. Let it get over any transport shock. transplant at end of growing season. I would pick off any fruit. The first year after I transplant too. Loosen the shipping ties on the stake.
