Hi there

not sure whether I understood right, did you start indevided clumps?

In general, 1year old or older clumps tend to grow huge but flower less.

I personally divide in fall already, as I have very limited storing room.

so, if the sprouts are not too long, ypu could de-pot and divide. If you cut right through fleshy parts, allow some time, a day or two for curing/dryinf off before repotting.

it would probably delay your plants but not kill them. Even of some sprouts break off in the process, they will resprout.

Don't know how many you've got. if you are not too sure you could splitt& repott some or half the plants.

another aspect with undivided clumps: if you grow them another year they get even bigger, are a nightmare to handle or to splitt.

personally, I would go for dividing.

and if the divisions sprout 3 or 4 sprouts that's not too bad, flowers tend to be smaller but more, so unless you grow dinnerplates, AAsized Dahlias, that's a good thing.

well, good Dahlia starting, bye, Lin

Thanks. I am a day late and dollar short. They are already too big to dig and divide. So I'll plant them and hope for the best. Next year I'll do a better job.
