We recently purchased and planted six small Crepe Myrtles, three in one location and three in another. One location has taken off nicely with many leaves and new growth. The other has nothing!! Any suggestions? When our order was shipped, all the trees looked rather like sticks with a very small root bulb. We followed all the online directions for planting. All the other trees are doing well.
If all three in one location are doing well and all three in a different location are not, through the process of elimination you might find that it's due to the difference in sunlight and/or soil between the two locations. I would start there, and this article may help you: https://www.gardeningknowhow.com/ornamental/trees/crepe-myrtle/crepe-myrtle-care.htm
