tubers not producing clump - how come????
Hi there, well just finished digging and what a disappointment!! This year about half my tubers did not form a clump like they normally would. They just had the mother tuber and maybe a couple very small new tubers. I've never experienced this before. Of course, this year I moved and started a new dahlia bed. The ground is very shallow - hard pan about 4 inches down. Any ideas what's caused this poor tuber production?? And any thoughts on whether I should save the mother tuber and try it again next year or just start over? I usually discard the original tuber, but hate to lose some of my favs.
Hope you're all almost done digging out there!! Kathy
