I have 10 rugosa hybrids, chose them because they are supposedly hardy and all the other good stuff. They have been a major disappointment: few flowers, masses of dieback, balling when it (hardly ever) rains, dead flowers hang on till doomsday. Any suggestions?

Hello Maddy and Welcome to Garden Delights.
Seems you are having a few problems, I don't grow Rugosa Hybrids but I am sure Pamela will be able to help you as she grows just about all varieties of roses.. And also lives closer to you than anyone else on this forum...
Good to see that you seen our link over on GW..

Hello Maddyr
Welcome, particularly a rose grower! I LOVE rugosas and think they are the best plant. Which ones do you have? I have about 60 Scabrosas down my driveway, some planted as baby bare-rooted ones last spring. I also have Belle Poitevine (1), Sarah van Fleet (1), Fimbriata (1), Agnes (1) and Frau Dagmar Hastrap (4). Now they do take a while to get going. Give them 3 years like most roses to strut their "stuff". I am particularly in love with the 5 Scabrosas that are now 5 years old.
The dieback is a worry as I never see dieback on the rugosas or maybe it is just that there is so much green foliage to the ground that I do not have a hope of seeing any stems. I have also never seen a 5 petalled bloom ball??? Are you sure you mean rugosas? I am sure you do as it is the subject of your thread.
I know Canberra is a fierce place for gardening with bitterly cold winters, which roses love, and no rain at all (almost) in summer. I was amazed at the poor state of the Old Parliament House rose gardens recently but their rugosas were fine. Of course they like water like all roses but rugosas are able to cope without water better than most plants - they are planted as freeway plantings in Europe. With the disease you describe, I'd be looking at your soil. I have a new rose (Madame Gregoire Stachelin to join another planted not far away) that was hidden by pots that is planted on my driveway which I just moved the pots (of things I bought a few months ago and have not had time to plant) and discovered this sad little one at the back of the pots but it was planted in the ground in the gravel outside my garage but under the roof so it gets no rain and this poor little one had dieback, powdery mildew and no leaves. The leaves of course are the lungs of the rose so if it cannot breathe, it is going to be poorly. With my sad one I will pile up some manure around it (fresh or old whatever) and I will put some seasol in water onto it and I bet it sprouts some new leaves real soon. I will not worry about the dieback until it is a much stronger plant with a big green lung and then I will snip off the dead branches.

Hi Maddy and welcome.
Knowledge is knowing a tomato is a fruit, wisdom is knowing not to use it in a fruit salad.
A ounce of common sense is worth more than a ton of intelligence.

Thankyou all for your welcome. I should obviously have put my rugosa problem on the Rose forum but got carried away. Pamela, I have 2 each of Vanguard, Pink Grootendorst, Roseraie de L'Hay, Souvenir de Philemon Couchet, Peony Blanc. They were planted in September 2005. I did hear they may take a while to settle down but really!! I put some nepeta plants in as the rugosa bed looked so bare originally. It has spread most energetically to the point where I'm always pulling great swathes of it out so I think the soil should be ok.
Elsewhere in the garden I have recently planted Zepherin Drouhin and her sport Kathleen Harrop and they have done really well.
I now have close to 70 roses and am always looking for spots to stick in some more. The rugosa bed I built especially for them and as it is a circular bed in the middle of the drive, their poor performance shrieks at every visitor. I can't even bear to look at them. And I bought them because I was sick of black spot! |
