Tubers dipped in wax tend to be very slow to develop eyes. For cultivars that develop eyes very late, storing the tubers in wax would seem unwise. For varieties that develop sprouts and feeder roots in December, the wax method would seem more sensible. However, the wax treatment has not become popular despite several articles promoting it. The failure of this method to become popular probably indicates that the extra effort is not worth the trouble.
Numerous containers work well for storing tubers.
While the discussion assumes coarse vermiculite, one can substitute wood chips without any additional changes. Add some vermiculite, put in some tubers, then add more vermiculite. Some growers use a separate bag for each clump. If a clump generates many divisions, one may need two bags. After filling the vegetable bags, stack them in doubled brown grocery bags and keep them in the coldest part of the basement or in another cool area that should stay around 40 to 45 degrees.
