Forcing rhubarb – covering the crowns to prevent light reaching them – will encourage the plants to make early growth.
These pale, forced stalks can be harvested for use in cooking when they are 20-30cm long and are a useful crop when there is little else in store from the garden.
Force the stems of established rhubarb plants only – young plants may not have sufficient energy reserves to produce early stems, and subsequent growth may be compromised.
Forcing rhubarb – covering the crowns to prevent light reaching them – will encourage the plants to make early growth.
You Will Need
- Large bucket, dustbin or decorative rhubarb forcer
- Straw (optional)
Total time: 15 minutes
Step 1
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.
Step 2
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.
Step 3
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.
