Dahlia tuber question.
I have some dahlia tubers which I have overwintered in the garage. They are now into their 3rd year. I don’t intend to plant them out for another couple of weeks and as they are a lot bigger than when I bought them I would like to divide them. There are no eyes visible yet, but as it’s quite cool in the garage should I bring them out in the day to warm them up a bit or do I leave them in the garage until the eyes appear? Thanks
