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...

Re: I'm new here, so I'd like to say hi!

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?

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.

Rob and Tom, you guys give me too much credit! I really don't know what I'm talking about. (I've never used any of those species -- it's all purely speculation.) Standard disclaimer on my part there. I am very good about opining about things about which I know very little. ;-) Not that I want to dis...

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...

Re: Rosa kweichowensis

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.

Interesting. Looking at the photo, I might have presumed something in the Rubus genus, without closer inspection or any visible fruit. (Move over, rubifolia!)

Re: Putting honey on stigmas before pollination??

I had wondered about using a sugar water solution on hesitant roses when the stigmas of such don't generally look "sticky" and ready to accept pollen at any stage during normal development. I thought about trying such on speculation that some reluctant mothers might just fail to trigger tube germina...
