Hello everyone - for the last three years I have kept 4 dahlias through the winter dry and frost free; all four produced shoots in spring and, after potting up, a good lot of flowers. This spring however only one has produced growth although the others are not rotted and look ok.
Any ideas - maybe it is just the end of their lives - after all nothing lives forever.

i've got dahlia stock that i've been growing for over 20 years....so they won't have reached the end of their life as such yet.
Why they haven't grown, difficult to say. Some varieties just don't produce many shoots. Some don't produce good tubers...when you dug them up last year, was there any sign of little eyes?
They should "come alive" after storage when compost temperature reaches 55'c...how long have you had them in pots waiting for them to grow?

Thanks everyone - maybe I am too impatient but last year they all sprouted within about 2 weeks and this year the one that has come up did so over a month ago so I think I'll give up on the "dead ones".
Thanks again - what a great site this is.

2 of mine have yet to sprout JM may still appear, or other thing is are they being eaten?
