I've had a few roses that have bloomed good all season, and for most of my repeat roses there were three distinct flushes, a few have had four and are working on the fifth. But then, my roses in front, with the exception of a few pretty much shut down. My big bed has been flowerless since the third flush. And I had even prepared for a nice fourth flush, especially since the temps had moderated somewhat and we've had plenty of rain. Every time I've checked, there's been no indication that there would be a single bloom in that bed, so I resigned myself to the fact that it wouldn't bloom again this season. Then, I just happened to check yesterday, and there are several that are setting on buds! Tiffany, Perfume Delight, Tropicana, Midas Touch and Poseidon for sure. I have several in that bed that aren't thriving, and I am planning to replace them, but I'm pleased that some of the more vigorous ones at least are going to bloom again. Seems like the past couple of seasons this has happened to some degree. I guess repeat roses take a long break some times, maybe after all the heat they need a long rest? I admit I don't really know the answer.
