Q.Why are all of my rhubarb stalks tough and woody?
I have always had beautiful rhubarb. This spring almost all of the stalks on my rhubarb plants are tough and woody. Is this preventable?
Generally rhubarb will become tough as the stalks grow bigger. I like to harvest my stems when they are about 10 inches tall.
