Mary Lee, good luck with your project. It was my success with roses in Austin that sent me happily down the path of rosemania. And it's not such a bad destination. You might find the
Gophinator to be of help.
Nacogdoches died its first winter here in zone 7b. Perhaps if I had heaped six inches of mulch over the crown in fall things would have been different. I'm sure your experience with Nacogdoches will be different from mine because our weather patterns in the spring are very different. We can get many freeze-thaw cycles in the spring. It can be 90F in February. It can be 20F in May. And it can make dozens of round trips between freezing and 70F in between. Tender roses tend to just die here.
