Rebecca says: I love rhubarb, not only to eat but as a decorative foliage accent in my garden. My "mother" plant has been divided many times, allowing me to embellish my gardens with drifts of this lovely plant. Rhubarb should be divided as early in the spring as possible. Divide it as you would any other plant: Dig up the root ball and slice it into chunks, making sure each division has at least one bud and a significant piece of root. Replant right away or store divisions in the refrigerator and rehydrate (soak in bucket of water for two hours) before planting. Water well after planting.
