Sulcorebutia crispata seed germination
Posted: Fri Nov 17, 2023 1:27 pm
I'm having poor success germinating crispata seeds.
Over the last few years I've tried 36 packets from various specialist continental suppliers, and bar some success with one packet of LAU390 it's been a poor return on my efforts. About 20 seedlings.
I'm getting much better success with other types of seeds, mostly South American cacti. About 25%. So I think my baggy method is fairly OK.
The propagator is at about low 20s degrees. It gets hotter on sunny days. I sow in March and dry them out before their first winter.
Is there something different I need to do to get a higher success rate with the Sulcorebutias?
I've obviously read articles of collectors in the field collecting seed that turns out sterile. Could a lot of this specialised seed be sterile?
One thing that did happen this year is that I got a lot of late germination. I noticed this when I opened the bags a few weeks ago. It's unlikely they will survive the winter as they are all drying out now.
This didn't happen with the Sulcos of course as they didn't germinate at all. But it might help diagnose my problem.
On a separate note I wonder does anybody know where I might get seeds of Willi Gertel collections, namely G245 to G255 approximately?
Does Willi himself sell seeds?
