Storing dahlias correctly

Since dahlias originate from sun-drenched Mexico, the tubers are very sensitive to frost and should be stored during the winter. They can only survive outdoors in extremely mild winters in very sheltered locations. If they are exposed to frost, they will not survive the winter. Mid-November is usually the ideal time to dig the tubers out of the ground. Then they will reward us again next year with particularly long-lasting, lush, and beautiful blooms.

As soon as the first night frosts appearmustThe dahlias are being prepared for their winter hibernation. While the tubers can remain in the ground for a while after the first frost, gaining some strength for the following spring, they should be stored quickly before a real frost sets in, when the soil freezes right down to the tuber's depth. We'll tell you what you need to keep in mind:

Now's the time to label the flowers with small tags, noting the variety, flower color, and height. This way, you can quickly decide next year which plants will best be placed together and which ones might be planted in the back row due to their taller growth.
Wait until the dahlia foliage wilts before digging them up. Before digging, cut all the stems a hand's breadth above the ground once all the flowers have faded.
Then, in dry weather, carefully dig up the tubers with a spade or digging fork and gently tap off any loose soil. Leave some extra soil around the tubers to prevent them from drying out.

Let the tubers dry for a few days in a warm, frost-free place. Check the tubers for damage and rotten spots and store only the undamaged, healthy ones. Rot spreads quickly and can destroy all the tubers.
Line a wooden box with newspaper and fill it with a thin, dry layer of peat and sand. Place the tubers on top and cover them with the peat and sand mixture. Make sure the tubers aren't touching each other.
The box is best stored in a frost-free, cool, and dry place. 6 degrees Celsius is ideal. If the humidity in the storage room is too high, there is a risk of the tubers rotting. If the air is too dry, they may shrink. If the room is too warm, the tubers may even sprout prematurely.
