Can I Start Hardening Off My Dahlias
I have four different varieties of Dahlia, Coral Jupiter, Bishop of Auckland, David Howard and Hillcrest Royal which I have grown on a sunny windowsill.
Can I start hardening them off or is it still to early. I was thinking to place them outside against a south facing wall and bring them in at night for a week or so.
I live in Birmingham, West Mids.
