Dahlia care in winter video

Stuff

Got the dahlia bug? Don't blame you!

How to look after dahlias over winter depends on where you live, how old the tubers are and what else you want to do with the garden space. 

If your soil freezes or gets sodden over winter, it's recommended to lift the tubers so they don't rot.

Otherwise, you can leave them where they are for a couple of years.

If you want to move them or grow something else in the space, you can lift them when the foliage dies down.

HERE'S HOW:

* Gently dig them out of the ground with a strong garden fork, brush off the soil and let them dry off.

* Trim off the stems and any fine roots.
