Dahlia dilemma

Reply from Kathy C

Hi, Faeza,
Dahlias as a general rule do not tolerate frost, freezing conditions, or wet ground very well so it is usually advised to lift and store them over winter. I have heard some gardeners say they leave their tubers in the ground all winter (even in areas prone to frost) and they do very well the next year. I suspect that is because the ground did not get too wet over the winter, even if it was very cold. If you live in southern parts of England, you might be able to get away with leaving them in the ground all winter, but it is best to apply a compost or a thick layer of bark to protect the tubers.
Is the entire tuber soft or just parts of it? If there are soft spots, you could try cutting out the offending sections and replant. There is no guarantee they will come back, but it is worth a try. If the whole thing is soft and mushy, I am afraid it will need to be discarded.
I hope this has been of some help. Please let me know how you get on with them.
Kathy C.

Dodgy dahlias..

Hi Faeza,
Kathys advice is good. It sounds like your tubers have rotted. Normally you'd take them out of their pots (or the ground) for the winter and store them in a fairly moist dark place.
