Q.I am growing 3 apple trees in my backyard. The leaves are starting to brown and some have holes in them. I am wondering what to
do? Are the trees in danger? The leaves are starting to brown on one of the trees, this tree was recently transplanted. The other two seem pretty happy other than strange brown spots that look like burn spots. There are also holes in the leaves and I was wondering if there was some sort of fungus or bug eating the trees.
A consistent watering regimen is needed immediately following planting to ensure that your new planting remains healthy and adapts to the new location.
