Is Graham Thomas resistant to leaf scorch/cane scald in hot, dry areas?

Thanks, Nate

If it gets enough water. To grow GT, I found that winter irrigation was needed. GT is not drought resistant.

Thanks Nastarana. Yes, heat scorch is affected by watering, but even WITH watering, many modern roses show scorch after the first 100 F+ heat wave.

So it sounds like GT was a winter grower for you, like one of the old Teas? Interesting. I had seen you mention GT's need for winter watering on gardenweb.

I noticed that GT bloomed best when there had been a rainy winter. One winter when there had been almost no rain, GT did not bloom at all. From that I concluded that winter irrigation was necessary for that rose.

After four years of fighting mildew--in dry southern California--- I am ready to shovel prune this giant. Nothing I have tried gets rid of the mildew. It's in full sun, is huge (six feet by six feet) and blooms constantly. Due to the mildew, leaves and blooms are stunted and unattractive. Suggestions please.

Powdery mildew may be exacerbated by dry soil (too far from spray heads, next to tree roots, etc), but I'm not positive on this (sorry). Heavy feeding with nitrogen may also exacerbate mildew, altho I'm not certain. Based on the 2 plants I've seen in southern California, Graham Thomas is moderately/slightly susceptible to mildew.

In my response you would think I'm a lawyer, but it's just hard to pinpoint causes/solutions to PM.

This rose thrives and gets bigger intenser colored flowers with a little bit of extra nitrogen.
