TUBEROUS BEGONIA--WINTER STORAGE
Dig tubers before frost. Roots may rot and decompose if soil temperature
goes below freezing. Cut tops back to within a couple inches of the tubers.
Dry in a warm location for 2 to 3 weeks. Check tubers carefully and discard
any diseased or damaged ones.
Store tubers in cardboard boxes between layers of vermiculite, peat
moss, sawdust or wood shavings. Place a two to three (2 to 3) inch layer
of material in the box and then a layer of the tuberous begonias. Cover
lightly with material and continue to layer. Store in a 45 to 55 degree
location.
Check tubers throughout the winter. If shriveling occurs, moisten packing
material lightly with water. If roots appear to be rooting or rotting,
move to a drier location temporarily; watch humidity levels and improve
air circulation.
