hi guys, I was wondering if anyone could tell me whether or not I should be watering the pots I have put dahlia tubers into.
I planted up several in pots last month and put in a window sill. One has leaves starting to show. Do I lightly water them regularly or leave them dry? This is my first time to try growing dahlias. Currently, they're in dry compost. I'm afraid I'll rot the tubers if I water.
