Seeds not germinating
Hi, can anyone advise on the above please? I’ve had columbine, forget-me-nots, verbena and water avens on the windowsill for what feels like months now (Except the water avens) but nothing is emerging. I’ve recently bought a heat mat hoping that will help as I’m on the west coast of Ireland and it’s not been the greatest of summers. Anyway, is it too late now, will the seeds have rotted? Should I start again or wait a bit longer? Thanks!
