it depends what your zone is my is zone5 and we have to dig them up and store them for the winter but if it don't freeze where you are you can leave them in the ground

Hi Jellyfish,

Dahlia tubers don't survive freezing as Sharon stated. I'm thinking you are in the UK and in hardiness zone 8.

If so, you should dig and store them for the winter. If that isn't possible, be sure to put lots of mulch or chopped leaves on top of the soil to keep them from freezing. Here's how to dig and store them.

Yes, I concur with NEWT. What is normally done is people store the dhalia tubers in a cool dark place for the winter (usually in peat). However, the harvesting of peat is very large environmental problem and therefore I'll recommend that you use cocoa bean hulls or some other alternative.

You can research peat alternatives with google if you can't find cocoa hulls.

(Cocoa hulls usually come in the form of a brick so, you would have to break the brick up(don't wet it or the tubers will rot over winter).

I wrap them in newspaper and put in cardboard boxes on a shelf in the garage for the winter. I put sulpher on to protect them from disease.

Thanks for the input Joanne, much appreciated.

I'll try that this year.
