If you’d like to get an earlier crop of rhubarb now is a good time to force it. Choose an established rhubarb in your garden and simply cover the crown with a forcing jar, upturned dustbin or very large pot. Doing this creates a dark and warm environment inside, forcing the stems into premature growth. Restricted light creates baby pink stalks which taste less tart and not as fibrous, ready approximately 8 weeks after covering.
However, once you force a crown you should allow it to crop naturally the following year (preferably two years of recovery), forcing it year after year could seriously weaken it. Before forcing, be sure to clear away the area around the base of the crown, removing decaying leaves and weeds to avoid the rhubarb crown rotting. Add a mulch of homemade compost or well-rotted manure to give a boost of nutrients.
A tip is to grow 3 crowns (providing you have the space), allow one to recover from being forced the previous year, force one and let the other crop naturally, when it should. A good variety for forcing is Victoria.
Our favourite rhubarb variety to grow is ‘Timperley Early’, it starts cropping naturally as early as March. If you grow this variety you have to get a wiggle on and force it earlier than other varieties to produce an earlier crop, usually December for cropping in February. As you can see, our young crowns (planted last year) are already well on their way to producing some fine stalks! They’re not established enough to start forcing them yet, it’ll be another year or two before we can use the forcing jars on them.
