You are lucky you can grow roses on the north side of your house! It'd be impossible for me here. Lucky CA rose growers! :)

I've been reading a lot on fertilizer recently just because I've been in the rose growing game for a year and a half so I'm a noob (lol), and Epsom salt or potassium would help. Maybe even some bone meal too for blooms? Is your soil at that place different from the rest you have, I noticed my heritage rose is a heavier feeder than my other Austins but I remembered the soil where heritage is, happens to be more sandy than the other places. I'm going to try to fertilize more bloom boosting vitamins so to speak next month on the heritage and see if that helps. Also I am really tempted to buy some rabbit manure from Craig'slist or something to top dress the soil with. I like that I won't have to wait to use it while it ages in my compost pile. Just trying to throw some ideas your way! If you already SPed it then take it for what it's worth and I hope you get something you like for that spot!

Sorry that Constance didn't put on any show after you committed all that space! She remains the most memorable rose I've ever grown. I bought four regular trellises and mounted them on a trio of 12 foot poles, and she covered the east end of the house and then scrambled along the top of the dog run!

She was completely cane-hardy in z6 central Ohio and what a show!

Mine was a grafted plant but it just may be that with all the old rose in her genes she wants a winter chill. Sorry she just didn't do her thing for you!

CS did well at Pixar and I don't imagine they had much more winter chill than I do. I suspect the warm days made the roses go fast. But they have done this three years in a row, and I have a better candidate for that spot waiting in the wings.

I actually don't mind once bloomers if they put on a decent display. Rambling Rector (blooming right now) is one of my favorite roses.

I agree that CS is one of the most beautiful roses ever, but in my garden the bloom is so fleeting that some years I don't see it at all. Well worth growing in the right zone, though I think I'd still prefer it grafted because of the gallica-like suckering.

I always had very few Austins and now I have even fewer. Munstead Wood and Lady of Shalott died this winter, an unusually mild winter but snowless and a couple of cold nights took its toll. I suppose I should have covered them but I don't winter cover any longer. Constance Spry was a dream for 15 years until it got severe stem canker. Graham Thomas and Abraham Darby are long gone. Three Austins now left are Summer Song, Lady Emma Hamilton and Crown Princess Margareta, unless one of the mislabeled roses from RVR is Mary Rose as suggested. I will not try more Austins.

I've started a new post-Austin bed with bushes with fall color in place of the apricot Austins and moved those who still live.
