While there may be some plants that thrive without any added fertiliser, rhubarb isn’t one of them. It will take everything you can give – sheep pellets, fertiliser, worm tea, compost and aged manure. Rhubarb is a long-term food crop and will provide stalks for many years once it gets established. Look after it well in the first couple of years to ensure the crowns are strong enough to allow for plentiful picking. Keep the crowns mulched in summer (but not covering them completely in order to avoid rot). To harvest stems, gently pull and twist the outer stalks rather than cutting or snapping them off, which can lead to fungal problems. Rhubarb gets redder when the weather’s cooler, so don’t panic if the stalks are more green than red. Taste is unaffected.
