How to force rhubarb

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.

Avoid forcing a single crown of rhubarb for two years in a row. Leave it to crop naturally instead, and always have more than one crown so you can force in alternate years.
