Question 1: Now that I have my first plan done, I'm looking to plant some more. Here is the thing though. The land is far from my residence. I am planting the trees not necessarily for human consumption (if I can eat a few while in the woods, great) but more for wildlife and the enjoyment it brings me. I will be able to take care of the trees to a degree, but spraying and such may not be a possibility. I'm looking for the hardiest types of apples, crabapples, or pears (perhaps) that will grow in my area and will be appealing to wildlife (and humans secondly). My soil has some clay in it, and I do have some areas that drain pretty well. PH is just over 5. Liming can be done if necessary. I'm in zone 5 in South Central NY.
Question 2: I also have a great site for some apples (gets over six hours of sun). Problem is that the land is also being overtaken by Autumn Olive which was planted in the early 70's. Any ideas on how to remove them without contanination problems? I can cut them down, but I think they will just come right back up again. Heavy machinery is not an option (the site is also near a pond).
