I thought that I would post an update.
Sometime in the spring, I checked and I had one of the two
trees I planted.
Our temps have been in the 110F' though we have had some rain.
I took a gallon of water and walked to where the bush is. It looked piqued so it is good that I watered it.
I also have three blackberry bushes since the Vitex bush was planted where my blackberry had been.
