Hibernate dahlias without a cellar - tips for alternatives
In many modern houses, there are no more cellars or only developed rooms. For the storage of dahlia tubers in winter, they are too warm. To hibernate your Georgians, you must seek alternatives.
Hibernate dahlias in cool, dry rooms
The ideal hibernation temperature for dahlias is between four and eight degrees. If it gets warmer, the Georgines go out too soon.
Alternatives to the cellar are as dry and cool premises as possible:
Do not store the tubers too tightly. The air must be able to circulate between the dahlia onions so that the tubers do not rot or mold.
Overwinter dahlias in the pot
Some hobby gardeners have successfully tried to overwinter dahlias in a pot. The pots should be kept as cool as possible and the Georgines should only occasionally get some water.
The danger that the dahlia bulbs in the earth nevertheless begin to rot is very great.
If you want to try it anyway, just overwinter those dahlias in the pot that you do not care so much about. Then you can handle a loss more easily.
Hibernate dahlias outside
Hibernating outside of dahlias can work under certain circumstances. In mild winters, the tubers of the Georgians do not freeze if well protected.
Unfortunately, you do not know how cold winter will be before. It is therefore important to excavate particularly beautiful varieties of dahlia beforehand and to overwinter them in a cool, frost-free place.
Tips & Tricks
If you overwinter your dahlias without a cellar, regular control of the tubers is important. Mold and fouling are contagious. Break off affected tubers and throw them away.
