Re: I think I'm killing my seeds

Thank you, Henry!
(Did I get Kuska and Karl mixed up in my mind? My apologies to both of you if so.)
Is there a lot of info on there on beneficial microbes and seed germinations as well?

Re: Help.. my babies are turning yellow!!!

Assuming you have ruled out pest damage, such as whitefly larvae (they can create yellow spots *similar* to what is in photos) the advice on fertilizers is same as I would have suggested. Yours looks more nutrient-related to my comparably inexperienced eye. If you go dilute enough, I see no harm in ...

Re: I think I'm killing my seeds

I wish I had the resources and self-discipline to do some experimenting. I fear I'm the one who planted the seed, so to speak, on charcoal. I mentioned that, many years ago, I had received seed from Joan Monteith in media in which she had added charcoal as an experiment. She was quite surprised when...

Re: experience with any of these in breeding (cold hardy reds & yellows)???

It's interesting to me to note that Étoile de Hollande, a parent of Red Dawn and a relatively tender HT, factors into this line of hardy roses. Is this a case of "pot stirring" in which the tenderness of EdH fell by the wayside while maintaining other aspects of hybrid tea-ness? Red Dawn is, in fact...

Re: Variegated roses?

I'll just follow up with the question: Do folks know if any of the known variegated foliage plants pass on genes for such, or are most such chimeras caused by something other than inherent genetics?

Re: Culling

"It is this process of selection that, generation after generation, shapes your roses into something that mirrors your personality."

A rose in declining health with a higher sense of self-worth than it merits, which deals with life by having a sense of humor about it.

That sounds pretty accurate.

Re: First germination of the winter

Good luck with those, Rob! I think Joe had gotten some nice results from LF if I recall correctly from a video he shot some time back. I don't recall if everything was single or if anything more full came from it, but I seem to remember some good yellows coming through even with near-species crosses...

Anybody using any of the old HT fav's of the 20th c.?

So... bagged bare roots are out at all the big box stores, and I concede that I was rather impressed with the selection at my local WalMart --large good-looking bagged plants from Certified on sale for under $7. They had over 40 varieties of the old standards, as well as a couple newer ones (e.g. La...

Re: stratifying in the south...

Joan, I think your space allotment/prioritizing seems about right for me. ;-) (2 bottles worth should hold an awful lot of seeds, and you *need* the space for other purposes!) But you confirm what I have suspected about temperature. We keep our fridge barely above freezing -- just enough to hopefull...

Re: First germination of the winter

I don't have much going on yet, but this seems as good a time as any to put in a plug for Lemon Fizz. I'm finding a good number of strong early germinations coming off her seeds -- much better than e.g. Carefree Beauty (no slacker herself) at this juncture. The one and only cross with Kordes' Soul S...

Re: Do more richly colored seedlings have more richly colored blooms?

I'm precociously senile, and apparently didn't archive some of the better links to color genetics in flowers written for the layman. Can anyone redirect me to such? And as an aside, would there be merit in creating a searchable rose-breeders wiki linked to this site where info such as this could be ...

Re: Is it just me? (On rose rustling...)

Well, to be clear, I'm not really concerned about knowledgeable folks taking cuttings off ancient plants. Honestly, provided it's not being done for profit, I can look the other way when someone propagates a patented rose, particularly if it is one that is very hard to obtain. My reaction is probabl...

Re: Is it just me? (On rose rustling...)

The ones you've read about would, I would expect, be the ones who as experienced rosarians did indeed find cultivars at the risk of extinction, and who are thus celebrated in writing for such. I doubt those that just pirate or obtain for free, patented plants, or who might end up ruining a hybridize...

Re: Is it just me? (On rose rustling...)

"Proper" rose rustlers, I am told, do not dig up plants, per the folks with whom I had the exchange, but rather propagate from cuttings for study and preservation. (In other words, they aren't really stealing the CD, just pirating it. ;-) ) I certainly understand the temptation, and perhaps I'm bein...

Is it just me? (On rose rustling...)

Do others view "rose rustling" with a skeptical eye? As an aspiring amateur hybridizer, I take a somewhat dim view of that which at times smacks of glorified piracy. (The "hobby" seems to be pretty highly romanticized and promoted in this part of the country.) The purported intent is to preserve his...

Re: Do more richly colored seedlings have more richly colored blooms?

In some cases, I think, yes. But I suspect it's a bit more complicated, although I should let someone with more knowledge answer that... My "favorite *yellow* flowers" for instance, are largely so *only* because they are held above dark, bronzed, young foliage. (I don't know that a "white gene" knoc...

Re: Do more richly colored seedlings have more richly colored blooms?

I have tended to assume the same likelihood, David, particularly when culling through species seedlings, though I don't have evidence to back that assumption up. Now that you have me thinking about it, with more complex hybrids, my inclination would be to be much less presumptuous. I do tend to thin...

Re: First germination of the winter

Congratulations, Rob. Fun times. This was a year of many aborted hips for me. (What have the bees got that I ain't got?) I nonetheless have a few crosses I'm looking forward to germinating in the fridge, and more than a few O.P.'s to help me familiarize myself with a new crop of prospective parents....
