A seemingly simple harvesting technique—cutting rhubarb with a knife—can silently destroy the plant’s crown by midsummer. What looks like a precise, clean method actually creates open wounds that invite fungal rot during the warm, wet conditions of late spring and early summer.
Most gardeners unknowingly destroy their rhubarb crowns by cutting stalks with a knife, leaving rotting stubs that invite disease. The solution is surprisingly simple: twist and pull instead. This single habit change can transform a declining patch into one that produces thick, healthy stalks for 30+ years.
