I've been trying to grow Roses in Miami for the longest time. I just don't do well with Roses. I've tried it all, not watering late, not watering from the top to avoid water on the foliage. I've given them a good soil mix, with plenty of room for growth and I prune often, but stilllllll. I have tried everything in order to prevent the dreaded black spots. I've come to the conclusion that I can't grow Roses.
To my surprise these miniatures are doing very well and I'm so HAPPY. I'm not touching them, they're in containers and so far so good. I cut them when I find new full blooms and I bring them in the house to enjoy. I think I'm sticking to miniatures.
