Rose Hybridizers Association Forum

Is it just me? Or have others noticed a marked decrease in offspring of roses yellow roses marketed by Kordes? A cursory search of HMF. Starting around 1995 with the release of Golden Gate. After quite sometime on the market. They are fewer roses released with these roses registered as their parents...

I have a 1200 gallon tank I want to use but it is clear plastic. I'm going to paint it and build a shed around it to keep out light. Donald, what ratio of chlorine bleach can you safely put in the holding tank? I need this system to manage itself. My fear is that the drip lines would become plugged ...

I've noticed a change in the weather there on the prairies. The winters are milder and less snow. The summers are dryer, with less predictable longer dry periods and huge down pours of rain over short periods. Last summer it became a question as to water the baby roses, or the vegetables. I'm lookin...

Warren, Those are some very healthy looking seedlings. My Therese Bugnet sets seeds very inconsistently from year to year.
I like your idea of bringing expand the range of Tea roses.

Hi warren, Austrailians lead the world in rainwater Harvesting and storage. They is a lot on the Internet on the subject. Can you please give us some pointers from your perspective as to what works, and what doesn't?
Thank you.

This is so cool to have so many input on this issue. As you can see from my Martin Frobisher seedling how chlorotic looks. I suspect that a disease like chlorosis can inhibit seed set and make the plant more susceptible to winter kill. Warren, I took your advice and secured some some large wheat str...

Does anyone have experience using Muriatic acid as an agent to lower the pH of irrigation water
for watering roses? Especially Rugosa roses? What could be the benefits and pitfalls?

Hi Warren,
Those are some very healthy Rugosa seedlings. Do you keep them in pots? Doesn't this retard the maturity?
What is the pH of your soil?

Watching lots of videos and reading articles on the art of embryo extraction. I've been successful in removing embryos
from large seeds like "Olympiad". But having difficulty working with small seeds like R. Arkansana.
Any suggestions?

Hi Paul, I love Rugosas too, but working with then here on the Eastern Prairies is not that easy or successful. Most Rugosas, if they survive, do not thrive. I think because of the high pH on our soils. Rugosas become chlorotic, which effect their ability to make through our winters. A few years ago...

Thanks to everyone for your insightful comments. Please keep them coming. I'll be coming back to this subject from time to time. One of the things I'm observing as I process these F1 hybrid seeds is the low seed set. Paul, in a recent thread, you wondered why Henry Marshall didn't use yellow Floribu...

More pictures.

Bringing the species into winter hardy yellows.

More species crosses.

Much have been written about breeding species roses into garden roses. The objectives of course is to eliminate the diseases garden roses and thus curtail the need for remedial spraying of harmful chemicals. Let me first say, I'm not a trained scientist. I'm hoping those who are trained in the scien...

Hi Jonathan,
A seed exchange is an excellent idea. But why USA only? I've received and sent seeds over the Canadian/USA border
with no problems.

Hi Tony, harvest the hips as you would cut flowers, and stick the stems in the damp sand. As you can see in my picture, I used one gallon pots with a trays under the pots. This way I can add a little water without disturbing the stems. The leaves may go mouldy, but keep an eye on the hips. This seem...

Hi Tony, I'm not sure what latitude you are and how much more "summery" weather you can expect. Here on the Canadian Prairies. The day time temperatures have dropped to plus 3 deg. Celsius. I was facing the same problems you have. Fellow RHA member Doug Wild of Alberta suggested using containers wit...

I'm trying this next year.

Stephen, just collected my first Dr. Eckener hips.

Thanks sharlene, my mis-labelled "westerland" does look like folklore. I'm delighted to see it was bred by Kordes. But my Google search pull up some dubious information:- http://www.google.ca/search?q=HMF+folklore+rose&ie=UTF-8&oe=UTF-8&hl=en&client=safari If anyone is famillar with Folklore, please...
