Dahlia care in winter
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.
* 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.
* Place in shallow trays of dry potting mix or sand that covers the tubers but leaves the crown exposed.
* Label well with the colour, height and variety name.
* Store in a cool, dry place and replant in spring.
