About Rhubarb
Rhubarb is extremely cold-hardy and productive — plant once and harvest stalks every spring for decades.
Plant crowns in spring. Never harvest the first year. Never eat the leaves — they are toxic. Mulch crowns in autumn. Divide every 5-7 years. Rhubarb actually improves after cold winters.
