Saxifraga germination

Submitted by Broekhuis on Sun, 02/15/2015 - 13:02

I've tried them with my standard treatment on filter paper (a few weeks at room temperature, 6-8 weeks in the fridge, and then back to room temperature under light), and I've also tried the sow-and-forget to pots set outside approach. All for nought. Is there a foolproof way of securing some seedlings?

"red". Two, perhaps three of these exist here still. I've encouraged the last and am taking notice of the next to last
listed here. Unlike Kabschias these are not insistent upon lime which may be why these "silvers" grow better in
