Over-winter Dahlia Tubers
(page 4)
Label Each Dahlia Tuber
Each dahlia tuber should now be identified even if they are all the same
variety - believe me you will have forgotten the name by next spring!
Common methods are marking the tuber with an indelible pen, or placing
all tubers of the same variety in plastic bag which is tagged with their name.

Store The Dahlia Tubers
|
There are many ways of storing your tubers over winter, you decide which is
best for you. The key factors are:
-
Temperature - keep the tubers in a frost free environment. A temperature
range of 35 - 45 Fahrenheit will suit them fine. In practice, the garage will normally provide the correct
environment.
-
Dark - keep the tubers covered away from light. Again, the garage
should be suitable.
-
Moisture - the tubers must be kept dry, but not allowed to dry out
completely. Surrounding them in peat, vermiculite or sawdust is a good way of achieving this.
|
| Four or five tubers are placed in a plastic bag
(pierced with small holes) with some sawdust to absorb
moisture. The bags are then placed in a plastic container
which will be covered to provide darkness. To provide a more
even temperature, the container is loosely filled with crumpled paper.
During the winter, examine the tubers each month, and throw away any
which show signs of rotting. If the tubers appear to be drying
out, open the bags and sprinkle with a small amount of water.
See April Mini-Projects for details of how to bring the tubers out of
winter storage and grow new dahlias.
