Thanks Topper for your quick response. I had to gather some of the information you requested, amoungst other pressing activities! First of all I live in the central part of Michigan, north of Saginaw about 20 miles. My tree is actually 10 years old (per my records). I lied about 6 apples as it only has 5 varieties! I planted it facing north and south(grafts going that direction). The south facing varieties are Top - Gravenstein, Middle - Jonagold, Bottom - Yellow Delicious. The north facing varieties are Top - Yellow Transparent, and Bottom - Melrose. There seems to be a branch in the middle, but I have no records of any variety. The tree is about 9 feet tall, and about 14 ft wide. As I traced back the branches, I have apples on the Jonagold (middle south) and the Yellow Transparent (north top). They both have good growth as well as the top south Gravenstein. The tree probably only gets about 3-4 hours of direct sun so I may have the problem you described. The top of the tree is pretty open so the top branches get good sun. I can see what you mean with the bottom branches in shade. I do have tall trees in the south that block from continuous sun. Should I attempt to prune the top branches more, or maybe I should resign myself to growing good apples at the top? The 5 variety tree caught my eye at the time back then, but I have other single variety trees doing much better, so I may need to be satisfied with getting 3 varieties off of that tree. Thanks again for your comments.
