Minis - disease resistant ?
Hi, I have only 1.5 yrs experience with a few roses, acquired by chance, description below.
In my limited experience with these roses, miniature roses are very prone to powdery mildew and black spot, by comparison to groundcover roses, growing side by side, infecting groundcovers. Some of them were described as disease resistant. I had to remove minis to another side of the house.
Is this common for miniature roses, or it's just my own rotten luck? If there are really disease resistant mini-floras and miniature roses, please advise on what to look for. Any low-growing rose will do, not only minis. Zone 6a, cold wet weather from fall to late spring, Great Lakes, full sun.
I really like HT-shaped large flowers and glossy dark green leaves of Vanilla Cordana and would prefer not to use small- and flat-flowered one, if there will be some choice.
My roses are:
Miniature ones - Vanilla Cordana (robust, big flowers), most common looking such as Sun Blaize (sp?), Parade, and popular "miniature rose", high shrub with bicolor very small flowers (red edges/white centers), miniature only flowers and leaves, not height/width of plant (Magic Carrousel?).
The only other roses I have are Flower Carpet groundcovers, pink, yellow and red (this one is least disease resistant). In comparison to my minis they are care-free.
