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!
