Q.Crepe Myrtle Root Has Been Gnawed
After the recent big wind here in eastern Virginia, I noticed a small crepe myrtle has blown over. When I picked it up, I noticed that the root had been completely gnawed away (and I found a burrow where the root used to be!). The nub of the root is covered with tooth marks. Could this have been a vole? We have lots of moles here and I’ve read that voles use the mole tunnels. I have lost vegetables to voles, but this is new. Everyone here has crepe myrtle. How did they all survive?

It very well could have been voles. This article will help you: https://www.gardeningknowhow.com/plant-problems/pests/animals/vole-control.htm
