The first rhubarb shoots will just be appearing on your allotment at the beginning of March and you can still force the stalks to encourage more early growth. Rhubarb that was forced last year should not be forced again this year so it is a good idea to have two crowns at different positions on your allotment so you can force them in alternate years.

Using a large forcing pot or an upturned dustbin, cover the crown completely to stop any light from getting to the stalks. If you want to quicken the process you can insulate the outside of the bin with straw to keep the heat in and the cold out.

The rhubarb can be picked about 4-6 weeks after forcing when the shoots will be long, slim and lighter in colour than regular rhubarb shoots.

Rhubarb can usually be forced depending on the climate, anywhere between December and early March.
