Many problems with mildew
Reply #1 of 3 posted 20 AUG 20 by Kim Rupert
Try increasing the water the plant receives. Yes, Mutabilis can be prone to mildew, but very often the mildew is a result of water stress. If possible, adding more water to help alleviate that water stress may well improve or even "cure" the mildew and is far less damaging than trying to spray with something to correct the issue. I had read in both E. B. LeGrice's and Jack Harkness' books that mildew can be forced by water stress, even on resistant types and in conditions which usually don't favor the fungal issue. I didn't believe it until I did it. Rust can also be forced by too severely water stressing many types.

Thank you for this information, Kim. I had always suspected that this was so, but it is great to have this confirmed. Best,

You're welcome, Brian. I hope that alleviates the issue for you.

According to H. Correvon, in 1894, Rosa Mutabilis could be R. chinenis x R.x odorata.

In zone 7b (and I imagine any zones warmer) Mutabilis tends to the larger size if not pruned, 5-6 feet wide and closer to 8-10 feet tall.
