Roses & black spot

Good link. But they neglect to mention that many antique roses are black spot resistant as well. I’ve never sprayed a rose for black spot, and my family has always grown roses. I’m under the impression that the tendency to black spot susceptiblity came into rose breeding with Chinas & thence into teas and then modern hybrids. I could be wrong. But I don’t grow any teas (too dicey in a climate with -20F temps in the winter) and the only rose I have which gets it is a David Austin I bought in a fit of greed in seeing its flowers. The rugosas, bless ’em, are nearly immune. My antiques are too. And the lovely books on roses by Martyn & Rix, and Peter Beales, give lists of immune/ resistant/ tolerant/ weeny varieties. Those books will however make you less resistant to buying more roses.

Now, the digging and dividing of perennials, the general autumn cleanup and the planting of spring bulbs are all an act of faith. One carries on before the altar of delayed gratification, until the ground freezes and you can’t do any more other than refill the bird feeder and gaze through the window, waiting for the snow. . . . Meanwhile, it helps to think of yourself as a pear tree or a tulip. You will blossom spectacularly in the spring, but only after the required period of chilling.
