You've got a ring of mulch around the base of the tree, which is great. But it needs to be much bigger. Put some wet cardboard down on top of the grass in a ring 6-8' in diameter, then pile wood chips atop the cardboard. Keep that mulch at least 6" deep and the tree should do well. The mulch and decomposing sod will provide nutrients and dampen the moisture fluctuations in the soil around the tree. After a few months, add mulch to maintain the depth. Wood chips are good, but any other organic matter (lawn clippings, fall leaves, etc.) will also do the job. If you don't kill the sod immediately around the tree, it will have a hard time competing with the grass for nutrients. Happy orcharding!
