In order to get the sweet, tender stems of pink rhubarb you’ll need to force them. This simply means excluding the light from the plant. You can buy special forcing jars to do the job, but a plastic compost bin you’re not using or a large dustbin work just as well and give large clumps plenty of space to shoot away. Place on top of the rhubarb crown when you start to see signs of life this month. In windy areas it’s worth weighing down plastic forcers with stones or bricks to keep them in place.
