We are interested in planting a Japanese Maple but we are uncertain if it will thrive in the spot we have picked for it. For over 30 years the location contained a beautiful bluish type spruce tree. It contracted a mite that destroyed one side of it and we had it taken down. The spruce stump was ground to a depth of 18-20 inches. In a 10 x 10 area I tilled in 40 lbs of granulated lime to sweeten the soil from the spruce needle residue. That has set fallow for approximately 8 months. The question is will this soil condition work for a Japanese Maple? We are located in northern Illinois, the soil is considered to be "heavy" with a clay layer down about 1 to 2 feet. The site in at the top of an east facing hill with partial shade from a large tulip tree. It would be partially shielded from the west by the house. It is near the driveway so we are interested in a tree that will remain on the small side. Our daughter in Columbus, OH has a beautiful Japanese Maple. It is about 30 years old and doing great. There is also a tree down the block from us that is about 20 years old and doing fine. I am not sure of the variety of either of these trees. My daughter's tree has bright red leaves in the spring. The neighborhood tree has redish orange leaves. Both are beautiful. We are mainly concerned about the likely acid condition of the rather heavy soil and how it would affect a Japanese Maple. Is there anything more I could do to prepare the soil for a Japanese Maple? Or should I give up and pick another type tree?
