I'm justgetting ready to order my first Mini's but have been growing large roses for a couple of years. I was told to treat them the same. I use 'Bayer ALL IN ONE' every 5-6 weeks because I don't like to spray. I add to water & water around the base of the plant. Its a fertilizer, insect & disease control all in one. So far it seems to do the trick. Maybe not 100%, but pretty good. I do supplement feedings though. Good luck.

I will try it! Thank you very much. I like Bayer's products.. they make a wonderfull Red Ant killer. Sounds to reason that the Bayer ALL IN ONE will work wonderful as well.

For someone just getting started and with just a few roses the Bayer product is the perfect solution.

Try putting corn meal around the base of your roses that have black spot. Works great.
