Rhubarb How to plant: In rich, well-drained soil with full sun exposure, some partial shade is ok. If soil texture is poor, incorporate generous amounts of well composted manure or vegetation into a trench 2 ft. wide and at least 18 inches deep. Firm root divisions into soil so that top ¼ of the division is above surrounding soil surface. Water thoroughly. To harvest: Allow newly planted divisions to grow one full year before harvesting any stalks. The second spring you may remove a few stalks for a three week period in early spring. Never totally defoliate plants. The third spring harvest may continue from early spring until hot weather begins. To remove stalks from plant: Grasp firmly at the base and gently pull away from crown, never cut them as this may damage roots or encourage crown rot. Feeding and care: Irrigate plants freely as soon as growth becomes visible in the spring, water is especially critical during hot, dry spells. A yearly application of vegetable-type fertilizer in springtime is beneficial. Mulch crown area with straw if winter temperatures drop below 20f. Remove flower stalks as they appear. Uses: Succulent stalks are usually boiled and used for preserves and pie filling. Rhubarb plants, with their attractive large leaves, also make a lovely addition to the landscape if you allow plenty of space to grow. Remember: Rhubarb leaves are toxic!
