Last month I planted two roses I bought at the local greenhouse in my bed which has adequate sunlight, good drainage, and is mulched with pine nuggets. My other roses are doing well, albeit they are minis that are well established. These new roses were rather root bound, I used a slow release fertiliser (Miracle Grow) which I've always used when I've planted. The last few days we've ended up with alot of rain. The leaves of both bushes are starting to yellow, no black spots, but they have brown spots, no mildew and no bugs that I can see although some of the leaves look like they've been eaten. Did I do something wrong, are my poor roses destined for the burn pile? Please give me some idea. I'm attaching photos so you can see what I'm speaking of.
