View as a pdf. Rhubarb Rheum rhabarbarum L. Rhubarb is an easy to grow, nutritious vegetable that can live in the garden for 10 to 15 years, and deserves more attention. Rhubarb prefers organic, rich, well drained soil for best growth. However, most soils are adequate as long as they are well drained. An inexpensive soil test can reveal potential soil problems as well as soil nutrient levels.
Visit the USU analytical lab website at www. Before planting, control all perennial weeds and incorporate 2 to 4 inches of well composted organic matter 6 inches deep into the soil where rhubarb is to be planted.
Rhubarb is almost always purchased as starts cuttings. Cuttings are taken from healthy crowns and should have at least one leaf bud on top and healthy roots that may have been trimmed on the bottom. Cuttings can be purchased online, via mail order or from local garden centers in late winter or early spring. Containerized, established plants are often available from local garden centers in late spring and early summer.
Popular commercial variety due to its sweet taste and excellent yield. Very likely to produce flower stalks that need removal.
Mature rhubarb plants grow over 3 feet in height and width. Place them where they will not interfere with other crops. In a sunny area, space plants every 3 feet. Plant crowns in early spring late March to mid-April in Northern Utah. Cover crowns with no more than 1 inch of soil.
Firmly press soil above and around crowns and then water well. If more than one row is planted, space rows 4 feet apart. For container grown plants, cover the top of the root-ball with 1 inch of garden soil. Planting crowns or established plants excessively deep delays maturity and can result in plant death. How often to irrigate rhubarb depends on soil type, sun exposure and outdoor temperatures. For the first 2 to 3 years after planting, irrigate one to two times weekly so water penetrates to the bottom of the root-ball usually 6 inches to a foot deep.
Mulch around plants with straw, grass clippings or bark to conserve soil moisture and reduce weed competition. Reduce irrigation frequency to once every 1 to 2 weeks after year 3, especially when mulch is applied around the plant. Irrigate so that water penetrates the soil 12 to 18 inches deep. Additional water may be needed during harvest in dry years.
Do not fertilize during the first year of establishment. Rhubarb occasionally produces flower stalks. Flowering tends to reduce plant vigor and leaf and petiole production. Flower stalks should be removed just as they begin to elongate. Depending on the variety and overall vigor, divide established plants every 5 to 10 years.
In early spring, before new growth begins, dig up the entire crown. Divide the crown so that there is one large bud to each section of crown and root. A healthy, mature crown generally produces 5 to 10 new plants. Replant 3 feet apart in a new area of the garden using planting procedures described above. Replant before or just as crown pieces begin to grow. In Utah, rhubarb is not generally impacted by many pests or diseases, as long as proper plant health is maintained and healthy starts are used.
To minimize risk, irrigate and fertilize properly and remove weeds from the growing area. An insect called the rhubarb curculio may cause minor damage by piercing stalks and feeding on plant juices. Rhubarb will get various root-rot diseases if over-irrigated or grown in wet soils. The disease red leaf has been reported in many states.
Leaves turn red and localized rot begins in the roots and then spreads throughout the plant. Other diseases are reported but are less common or are not present in Utah due to our dry climate. For assistance identifying and managing plant problems, contact your local USU Extension office.
Do not harvest any stalks for the first 2 years. In the third year, stalks can be harvested for 3 to 4 weeks. After the fourth year, harvest stalks for 6 to 10 weeks or until plants begin to lose vigor. Stalks are ready for harvest when the petiole is 10 to 15 inches long. To remove, grasp the stalk just below the leaf and pull upwards and to one side. Only the stalks are edible, so all leaves should be removed and discarded.
Never cut stalks from the base of the plant. This leaves plant tissue potentially open as a disease entry point. Depending on the variety and growing conditions, between 4 to 12 lbs of stalks can be harvested annually per plant. Fresh stalks can be refrigerated for 2 to 4 weeks in plastics sacks. Stalks can also be frozen. Blanch stalks in boiling water for 1 minute.
Promptly cool blanched stalks in an ice bath to preserve crispness and color. Pack stalks tightly into containers and freeze with or without sugar. When canning, 7 pounds of rhubarb is needed to fill nine pint bottles. The added sugar draws out plant juices. Allow this mix to stand until juice appears. Boil filled jars in a water bath for 20 minutes at elevations of 1, to 6, feet and 25 minutes at elevations above 6, feet.
Why are the stalks on my rhubarb so thin? Stalk petiole size is influenced by plant health, age, and variety. Over harvesting, poor nutrition, inadequate water, or other stresses temperature all affect stalk size.
As plants get older and more crowded, stalk size also decreases. Finally, some varieties produce larger or smaller stalks. Why do you discard the leaves after harvesting the petioles? Rhubarb leaves contain high concentrations of oxalic acid that can make you quite sick and lead to kidney failure.
The stalks on the other hand have almost no oxalic acid. Animals are also susceptible to this poisoning so leaves should not be fed to livestock. Discard the leaves into the compost pile or leave in the garden as a mulch.
