I've started my first garden and have decided to do mostly containers -- our soil is very dense. I have 4 miniature roses in pots and they aren't doing very well. One plant had a nasty case of dusty mildew and now 70% of the leaves have yellowed. The others seem to have stopped blooming (blooms have browned and dried). I deadheaded in hopes of encouraging more blooms, but nothing has come up. The foliage on the other 3 plants seems healthy. I readily admit that I'm pretty naÃ¯ve when it comes to mini roses... am I expecting too much from these little plants? Is there such a thing as buying a "bad plant"...?
Would also some advice on how to transition them indoors when the weather cools.
