The only good thing I can say is that he has a good selection.
You can't just show up, you have to call ahead so he can approve of you coming by to look at his trees. If you don't know much about the plant you're looking at, don't expect to get much info from him. His answers are always short and it feels like he just wants you to hurry and buy something and leave.
Bad experience overall. The only reason I'd go back there is if I absolutely cannot find the tree I'm looking for elsewhere.
