Keep dahlia tubers?

Port Sanilac, MI

Another stupid question. I am digging up a few of my dahlias and see that there is very little growth on them except for the old tuber and some very skinny "roots?".They were the ones that weren't growing very well to start with so I know I can't expect much. With iris you toss the "Mother" because she won't bloom again; is that true with dahlias? Will the old one produce next year if it is good and solid? Those long skinny things, they won't develop into tubers will they? Have any advice, other than "You are too dumb to grow dahlias, give them all to me" grin. Kay

Many dahlia places advocate discarding the mother tuber but it can generate new growth so I'd say to keep it if you love the flower. Those skinny roots generally won't produce a thing. The only way any of us learn is by asking questions and none of yours were dumb so have faith and good luck.

Pirl: Thank you so much for answering me. I will keep the mother tuber if I don't see any obivious life on the new ones.

You're quite welcome.

I've been leaving the mother tuber if it looked good and haven't had a problem with them.

If the new tubers (skinny roots) are thicker than a pencil they are good. I haven't had much luck with mother tubers but it's worth a shot.
