I'm not sure what the problem is but I am sure that watering, even a new one, every day until the ground is waterlogged is not a good idea. In warm and dry weather I would water the tree only every couple of weeks. If there has been rain, no watering at all.
Hello Gay, the fact that the tree is open to the east already means that it won't be consuming very much water and it will be exposed to cold winds. Waterlogging is not good for any fruit tree, unless it is growing very vigorously or has a large canopy- in a south facing position.
Try mulching intead of over watering and prune it while it's growing well (in June) to stimulate growth and ensure that it doesn't catch silver-leaf fungus.
