Re: Germination Issues or Impatience

Personal opinion based on N=1 experiments. Freezing rose seeds directly and suddenly may be fatal to them. I got zero germination from Pink Meidiland that had been deliberately frozen in hips to 0 F, for a couple months, after some weeks in fridge. A couple possibilities. Maybe very slow freezing is...

Re: Germination Issues or Impatience

This year I had sufficient of some kinds that I did a couple tests. I put some Carefree Sunshine and Rainbow KO at room temp, and also an unknown very good yellow shrub that I call TCY. Then at intervals of a month I've put them into the cold. Of the CS at R.T. I've had about 1 seed in each bag of 1...

Re: system for producing smoke solutions

Thank you Henry. Unfortunately the Bioone website is under maintenance for 16 hr right now. So I'll wait to see what they rigged up. One complication of working with smoke water is that its really hard to know the concentration of the active constituents. I contacted Gavin Flematti at Univ W. Austra...

Re: How Do You Take Care of Newly Germinated Seeds

I've been following pretty much the same routine for a long time. I use 6-paks (12/tray) with 2 seed/place, so total 144/tray. 2trays/4 ft shoplight. As Paul notes, some seeds open but don't grow. My impression, it is about the seedling, not the planting. I check once a month in a fridge (or sometim...

Re: Tahitian Treasure Grandiflora Rose

I had Brite Eyes last year and it was quite good here- disease-wise. But not the bloomer for me in a pot that White Out was on campus in the ground. I realize that's not a completely fair comparison of floriferousness. But BE grows rather tall while WO is quite compact like Rainbow KO, much shorter ...

Re: Tahitian Treasure Grandiflora Rose

I have been silent for a while due to insufficient gravity. Maybe you know of the "Princess who lost her gravity". If not, definitely worth finding and reading. I would recommend giving a try to White Out. Can't say what color offspring it might yield but it produces a fair OP seed from here on K-St...
