I think he's talking about Zoe's store, Tranquility Bonsai. She closed because her parents were sick and she needed to take care of them out of state. She did have a great going out of business sale.
Cabrerra Farms has a nice selection of trees. I try to go there once a month. I don't think they sell tools though. I would definately look them up when you are in Houston. Good luck finding the nursery. It took me almost an hour with a map.
