This is my third year growing bedding Dahlias (have had good success!), but only my second year
growing "regular" Dahlias. Bought the tubers in a package at WalMart, package was labeled "BiColor Duet". Planted after all danger of frost, took forever to sprout. Beautiful flowers, but all
the plants quit flowering around the end of August, although foliage was still lush & green. Decided
to dig the tubers up yesterday for winter storage, and while there were some "roots" underground
where the tubers should be, there were NO tubers at all. Same thing happened last year, but I figured
I'd done something wrong due to inexperience growing Dahlias. What could have caused this? We've had much higher-than-average rainfall over the summer (record breaking some weeks), could
the excessive rain have caused the tubers to rot & disappear?? I did not fertilize the Dahlias, and
they (BiColor Duet) had no problems with pests, so no chemicals applied. Just quit flowering early
and now no tubers left to store.
