Storing Dahlias Over Winter

Dahlias provide a striking show from late summer into early fall. After the first frost though in Wisconsin I need to dig them out because they don’t survive our winters.

Digging Dahlia Out:
After that first hard frost, the tops will blacken. You should cut the flower stalks 6 inches above the ground. Then take a pitch fork and push it into the soil working your way in a complete circle about a foot away from the stem. Now go back and gently pry the clump. Label the stem of each clump with the varieties name and the color.

Set the clump out in the sun to dry the soil. It is best to turn the stem on it’s side or with the dirt side up to dry it. Before night fall, gather up your clumps and shake off any extra soil without damaging your roots. Do not leave them out overnight night for fear of frost.

Storing Preparation and Storage:
Take each clump and dust with powdered sulfer this will protect against rot during winter storage. Wrap each clump in dry newspaper and place them into a cardboard box. Store them in a dry place with temps between 35-50 degrees.
Check on your roots every month. If they have shriveled a quick spray of water and they will firm back up.

Planting In Spring:
If you would like to divide your dahlias, now would be the time to do so. If not, you can go ahead and replant them after the dangers of frost.
