Clear around the base of a rhubarb crown, removing old leaves and weeds.Add a mulch of well-rotted manure or homemade garden compost to boost nutrient levels and aid growth.
Use a large pot, dustbin or decorative rhubarb forcer to cover the crown. Plug any holes to exclude light. In cold regions or to speed forcing, insulate the outside of the pot with a thick layer of straw or bubble wrap.
The forced stems should be ready to harvest eight weeks after covering.Gently pull the stems from the base of the crown, and remove the poisonous leaves before eating.
