Bought two crape mytle trees a month ago and they are tall. We started off putting root stimulator in the hole, then the tree, and then put Miracle Gro ground soil; but one of the tree's leaves are turning yellow and the leaves are wilting. What can I do to save this tree?

They are likely not getting enough water. Water deeply and daily for 2 weeks, then water 1-2 times a week after that for the rest of the summer. Newly planted trees need large amounts of water to establish well. This article will help: https://www.gardeningknowhow.com/ornamental/trees/tgen/watering-newly-planted-tree.htm
