I went organic some 2 years ago and the best I've found is Compost tea. It seems to cure all of the problems I've seen in my area.
Seems simple enough. Do a Google search, have a good read, then give it a try.

my trees did poorly the 1st 2 years. based on advice I got here I fertilized with urea (a high nitrogen fertlizer). if your soil is sandy and well drained theres a definite chance your soil is nitrogen deficient. It made a huge difference for my trees.

do a soil test. Note you can't fertilize too late in the summer or the trees are at risk for winter kill as they don't harden off properly for winter.

Thanks for the replies. I've read in lots of places not to fertilize in the first year, but I think it's worth doing a soil test. The county extension is big on that and practically does it for free. It's not sandy soil, though.

As for compost tea, I'm willing to give it a shot. I've heard raves as well as some criticism of it (mainly just skepticism that it works). Beeman, may I ask whether you follow some kind of schedule?

Thanks again!

The must-do is give them deer and rabbit protection. Otherwise you may not have any trees to worry about come spring. Northwoodswis4

Hi I planted three different (for pollination) semi-dwarf apples five years ago; they arrived as three year old trees from Raintree Nursery. They take a while; about three years to really start taking, but after the second year I had a tiny crop of two apples. It only goes up from there! Hang in and make sure you water them often. They will be fine. Good Luck!
