Pulsatilla from seed

(1/7) > >>

Catwheazle:
Hello,
I would like to know what your experiences with Pulsatilla seeds are like. For ir it fluctuates from 100% to 0% Fresh seeds sown in summer or early autumn germinated after about 2 weeks without problems. I had the one in the winter garden with high daytime temperatures and a strong day / night reduction. I got semen again 3 weeks ago. I had it in the living room at around 20 ° for 2 weeks, ... nothing :-( Then I wanted to spend another 2 weeks in the unheated winter garden (around 10 - 15 °) and then outside. Now, 1 has germinated in the winter garden . Of course I leave this pot. What was the trigger? Should I try the 20 ° in the living room again? Should I provide (heating) strong day / night cooling in the winter garden?
Are there differences between the different types?
Please tell me about your experiences as fresh semen is unfortunately not always available.
greetings
Bernd
Oh yes, almost forgot: light germs or dark germs?

I always sow Pulsatilla seeds when I get them and place them in my cool greenhouse. Some batches do germinate in fall but most germinate during winter/early spring. The greenhouse is not frost free but usually we don't have many days/nights with frost here.

Catwheazle:
thanks for your informations :-)

Hi Bernd, as they are Ranunculaceae which tend to be short-lived, I usually sow Pulsatilla as soon as I get them. I usually break off the plumes in case these act as a source of rot, though I don't know if this is necessary.

Generally if the seed is fresh it comes up as long as the weather is not too cold. I've never experimented with triggers though, sorry.

Best wishes and Merry Christmas, Tristan

Hello hoy,
this year I did it as you wrote it ... and it works very well :-)
This year all sown species came one after the other :-)
I even have the impression that they germinate and grow better at currently 15 ° C and additional lighting than at room temperature.
greetings
Bernd
