Forcing Rhubarb In Winter
Rhubarb can be grown year round. You can grow tender stalks out of season by "forcing" rhubarb at home during the late winter and early spring. Forcing is most successful with large diameter roots. Dig up the roots of plants that are to be forced (three-year-old plants are best) keeping excess soil on the roots to prevent damage from subzero freezing. Pot them in large pots and leave them outside exposed to several hard freezes. After the roots are thoroughly chilled, take them indoors to a warm (with a temperature of 50 to 65 F), dark place (a cellar, hot bed, etc.) and cover them with peat, soil, or sawdust. A wooden bushel basket makes an ideal container for forcing.
