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.

Although this is one of my favourite roses - beautiful bloom, rich colour and wonderful fragrance - it has rather poor disease resistance - all 5 of mine get quite bad blackspot early in the season, but do seem to recover. It is not a small rose - and needs room or climbing support. Very good as small climber - except for the disease resistance. Not up to modern standards in this respect, but because I am so fond of it, I forgive it its faults.
