i have a dahlia in a pot thats still refused to sprout shoots. the tubers seem firm and undamaged/disease free.

its been rather chilly overnights here in the uk, thought it might be that thats prevented new growth so i brought the pot inside but to no avail.

anybody know what to do? thanks.

Heat helps, I usually put my tubers on top of my fluorescent lights, when I am trying to wake them up in the spring. If it hasn't sprouted by the middle of July then I would probably just give up on it.

Not much help - sorry

I agree with Geof. I have two that won't get growing and this is their last day here.

Hello, is there a reasonable state of the art/ or Trade percentage of success rate that could be used for us dahlia lovers. In the dry seed trade packets usually it is written: the expected minimum germination rate. Is there such an accepted rate for dahlia tuber's that were bought in the trade, specially when they travel from so far away? ( mine migrate all the way from Holland out to northwestern Patagonia where I grow my dahlias). At least knowing what is reasonable to expect reduces frustration. I'm now at the stage where I've got to wait for my tubers to sprout. Yesterady I finished potting them and they are placed in one of my warm greenhouses. They stay there for a month and if everything goes well they go into the ground by December when I lift my spring bulbs. thank you for your help. Arturo
