Dahlia Query Again!!
I very kindly got good advice last year on dahlia tubers which I had planted for the first time. After storing over winter I have a few weeks ago planted them in pots in an unheated greenhouse. I watered them when I planted them but we have had some 'warm' days over the past few weeks. Last year I didn't water them at all after planting following advice here but I can see that the compost is very dry even at the bottom. My question is should I give some water or just leave well alone. Or move out the greenhouse and put into a shed instead. Thanks.
