Re: Rose replant disease?

Dr. Zlesak's article (cited in Henry's post) might be the same one that was reprinted in an RHA newsletter a couple years back. But I had not recalled David's observation (which probably initially planted the seed in my mind): "Hearing Winkelmann’s presentation and observing how rose growers handled...

Rose replant disease?

When evaluating your seedlings, do you more experienced hybridizers sometimes plant them out in the ground? And if your realty is limited, requiring you to replant where rejected seedlings were previously grown, do you worry about the risks of Rose Replant Disease and the difficulties it might prese...

Re: Show and Tell?

I've been somewhat AWOL for a bit, and have missed a few neat posts. Jonathan, those are some pretty cool seedlings from Palustris. I particularly like the R. fedt. foliage, as well as that of the first R. rox. cross, and will be curious as to what those will offer moving forward. Is the last one al...

Re: inside-the-north-texas-fight-to-stop-rose-rosette/

Is there any indication that pruning equipment can spread RRD? I've reported a grouping of KO roses about 1 1/2 mi. from my house recently. (Panicking) The shrubs are semi-annually sheered by the landscape company that services the commercial property. Half the plants are dead/dying already, and the...

Re: Something interesting...

Kinda making me want to acquire Roger Lambelin. I wonder what percentage of seedling (if the pedigree of Bonkers is correct) can yield such results. (And how hard it is to get strong health into a seedling of RL!) Cool seedlings, Kim.

An interesting grafting tool...(?)

Dunno if appropriate to share marketing stuff, particularly as I cannot vouch for this product, but saw an ad and thought this looked intriguing. https://www.renicart.com/products/grafting-tool-kit I wonder how well it might work for roses. (I realize *most* grafts provide a branching base, and not ...

Re: Odd little seedling

Cool, Joe. Never had one do anything but the very opposite!

Dumb question, but as I don't dabble in such... Would grafting that to an appropriate root stock change its demeanor?

Re: Can any give suggestions on these roses for breeding?

"The majority of roses I chose either based on suggestions to use as parents, because I like the color/traits, or because they seemed to be used successfully for crosses in Help Me Find" That was once my thinking as well, but I would suggest that what that means is you are ultimately selecting for r...

Hi, Josh. Welcome! I don't know that you should worry about not being "ready" to be involved in "serious conversation". I consider myself exceptionally green at this, and that never hindered my chiming in. ;-) Having said that, DO take comments from me with a grain of salt! From my limited experienc...

Re: Why some crosses fail

Thanks Karl! I think that when I find time to peruse all the articles, this will address a number of questions I was trying to ask (but probably did poorly) in a prior thread.

Re: Show and Tell?

Thanks for the response. I personally have had nothing worth photographing this year, IMO, though I have had a couple seemingly exhibiting admirable health, and giving me the impression that *were* I to relocate to a better site, they might be rather floriferous. It's just that the blooms thus far l...

Show and Tell?

I don't have anything of much interest to show for this season, and so I'd like to revert to vicarious enjoyment of other's successes in one thread. I'm assuming it's late enough in the season that folks have had opportunity to enjoy the fruits of previous year's hybridizing labors. Caveats as to no...

Re: Grid for pollen measurement

Cool! Slightly OT, but I'm curious as to what kind of magnification would be required to view root-squashes to determine ploidy? I'm assuming that's requires a heckuva lot more magnification?

Re: in the rose family

Those are impressive, Stephen. Have you thought about how many acres worth, and how many bushels ultimately, those are good for? That should make you feel better about your pace, I would imagine.

Re: Variegated roses?

Dumb question, but if it's a seedling from parents that don't present similar signs of "virus" and if the seedling has never been grafted, isn't the probability of such ridiculously slim? *If* it were a virus, is it conceivable that the carrier for the virus would *not* have exhibited such extreme v...

Re: Helpful tip plant markers

"the old string and paper rolled wax pencil" sounds like what I call a china marker. I thought it would be a great solution too, but found that the pigment in the ones I bought faded pretty quickly in the sunlight at our latitude, much to my surprise. Perhaps you have found a better brand? *When* an...

Yes. I couldn't really tell, but the carpels on that first photo also looked to be the type to form drupelets, hence my comment on fruit. Presumably, however, there *is* such a rose, erroneous photo notwithstanding, no?

Re: rugosa x glauca seedling

I wonder if R. fedtshenkoana derivatives could reinforce the foliar color, or if R. foliolosa derivatives might serve to reinforce flower color? Dunno if R. f. could, in and of itself, bring back some rebloom. I have not worked with any of those species yet, though they have long been on my wish-list.
