Rootstock. Best for Texas? Fortunia?
I recall talking to a great rose shower around here that said he has much better performance on his HT's with grafts on Fortunia? As opposed to Dr. Huey. (not sure it was Fortunia, but recall it was as opposed to dr. Huey).
How does one know? Even at my local (good) nursery, I wonder if they would know what a rose is grafted on? Sometimes I seem to know more about roses than the sales staff. And it doesn't say on the tags.
Also, what do the different rootstocks have as advantages? I don't need freeze tolerance. What ARE the advantages of each. I do prefer own root, but it is not always available.
Thx in advance if you know this stuff and can explain!
