What is the best way to store Dahlia Tubors over the winter months?

I leave about three inches of old stalk attached to the tubers and lay them down in an empty seed tray and cover them loosely with compost / soil. I then keep them in an unheated greenhouse in the dry.


By spring time they will have started to show signs of life with tiny new growth. As soon as these become established and the weather has warmed up a little, (in the UK by the end of May), then they are ready to plant out.


I hope this helps.

What is the best way to store Dahlia Tubors over the winter months?
We just cut ours down the other day and covered them with about a foot of leaves and a tarp. Here in Wa. we don't get real cold winters but it is most often wet. We stored them in a box of wood shavings last year and the results were less than ideal. Maybe we didn't clean them good enough but some of them molded. I had them in a dry storage shed. This year we are trying "leave them in the ground".
Reply:It gets very cold where I am in northern VT. My mother-in-law has lived here (with Dahlias in her garden) for 14 years. They have to be dug up each fall (we dug ours up a couple of weeks ago), and stored in a paper bag or cardboard box in the basement. She has never had a problem with them coming back after re-planting them in the spring. Darn things spread so much that every fall she splits the tubes and give half of them away.





Good luck!
Reply:We store ours in peat moss ,from time to time give the peat moss a mist with water to keep it damp in order to prevent the tubers from drying out. Just like when you buy the tubers from the store ! same idea except in cardboard boxes .

Reply:I don't know where you live, but I've found the best way to keep them, is leave them in the ground with a mulch over them! Tried digging them up and leaving them in the shed in a brown bag, but plants either didn't grow or were disappointing in subsequent year. Left them in last year and had a fantastic show this summer. Winters are much milder now. Try leaving some in as an experiment,
Reply:You can lift them, let them dry a day and then pack them in paper bags with slightly damp peat. But I have found them to be fussy, so I leave them in the ground on my south-facing slope. We are in zone 7 and they make it as long as I put mulch on them.
