Some varieties of apple show more leaf curl than others, and it is not
necessarily harmful to the trees. If you see other signs like early leaf
dropping, or it is affecting
the fruit production (too soon in your case), then I would begin to get
concerned. I
am in zone 5, but I think my remarks would hold for you. Not sure if you are
trying
to attract or deter these critters? Almost anything that can climb a tree would
be a
potential problem. Sounds like you are taking the proper measures to protect
the
trees. By the way, try and use a spell checker on your postings, it will avoid
any
misunderstandings in what you are trying to convey.

Hi all...just planted up 50 4 year old grafteds in what i hope to
become an orchard. Stock was sposed to be disease and insect free on
arival from Alberta grower (cold zone, need standard stock trees, not
dwarf or semi-dwarf).
Noted leaf curl on "red baron" variety of apple (no, not the crab apple
red baron, but a hybrid they came out with out west) but not on the
other varieties. soils are heavily conditioned here with peat moss and
horse manure as topsoils is sandy, acidic and sparse.
Are some plants more sus to diseases?
Am also collected wild apple seeds for some grafting experimnets i plan
on doing next spring.

Yes, i faithfully sprayed for bugs and disease every two weeks and even
went so far as to spray the surrounding bush crabapples and hawthorns.
No maggots, but obvious other signs of distress.
Anyone else growing apples in hostile 3A/B zones? Besides deer rabbits
and mice, what other winter killlers do i have to look forward to?
Cheers, had to do the apple thing to attract deer and wild turkeys to
the property. Yes, the trees are fenced high and tight.
