Perennial seedlings - what now
Hi Everyone, I am a total newbie and need a bit of advice if possible.
I planted up some perennial seeds about 6 weeks ago and now have a few trays of seedlings. These are Monarda, Echinacea, Astrantia, Aquilegia, Geranium and Primula etc.
Do I need to get these under cover or do I just leave them out in the garden over the winter?
