Need advice on thinning overwintered dahilas
I managed to overwinter 13 clumps of dahlias this past winter and now they are starting to sprout multiple stems. What recommendations do people have for thinning? Should I thin down to only one stalk? I am growing them specifically to use as cut flowers so that information may make a difference in how I should thin and prune them. I want lots of long straight thin (but strong) stems so maybe multiple stems from the clump would be better.. I'm not really concerned about the size of the flowers.
