Hi all,
I have naturalised some cowslip plants in my lawn and would now like
to increase stocks....
For the last couple of years I have collected seed without success
in growing plants..
Is there a knack to it?
I have just been using Sifted multipurpose compost so far.
Any theories welcomed as it would be great to have a lot more in my
lawn brightening up springtime.
Thanks,
Paul.
Assuming that primroses are the same I also look forward to help. I
cannot get them to germinate, I have tried placing them in the fridge,
to no avail. Yet in my last house I had cowslips which self germinated
no problem!

Many Primulas germinate better when the seed is sown fresh.
