In May we planted a pink dogwood on the east side of the house in a fairly sheltered area. It looked very healthy except for a few higher leaves that had turned a bit reddish brown. We thought it could be a bit sun-burned. We followed reliable planting instructions and added bonemeal and if I remember correctly, some compost. NOW, all of the leaves are reddish brown,drooping and some are dry to the point of crispness! At first we decided to water more frequently but the highest leaves are still getting worse. Did we use too much bonemeal? Was the compost a bad idea? Can this tree be saved? HOW.
