Rhubarb, a perennial vegetable often heralded as a fruit, is a resilient and versatile plant that thrives in various climates. For gardeners in Montana, growing rhubarb can be both rewarding and straightforward with the right techniques and considerations. This article will guide you through the steps necessary to successfully cultivate rhubarb in Montana, including planting, care, harvest, and common challenges.
Rhubarb (Rheum rhabarbarum) is known for its tart, flavorful stalks that can be used in pies, jams, and other recipes. It’s considered a vegetable but is commonly treated like a fruit in culinary practices. The stalks are edible, while the leaves contain oxalic acid and should not be consumed.
Montana’s varied climate presents unique challenges and opportunities for rhubarb cultivation. The state experiences cold winters and warm summers, making it well-suited for growing this hardy plant. Rhubarb thrives best in USDA hardiness zones 3 to 8, which covers most of Montana.
While there are several varieties of rhubarb, it’s crucial to choose types that can thrive in Montana’s climate. Some recommended varieties include:
Selecting local or regionally adapted seed sources can help ensure better success in your garden.
The best time to plant rhubarb in Montana is early spring as soon as the ground is workable or in the fall (late August to early September). If you choose to plant in spring, aim for a time when temperatures are consistently above freezing.
Rhubarb requires consistent moisture but does not tolerate standing water. Water plants deeply once a week during dry spells or when rainfall is scarce.
In early spring, apply a balanced fertilizer rich in nitrogen before new growth begins. Follow package instructions for application rates based on your garden size.
Keep weeds under control during the growing season as they can compete with rhubarb for nutrients and water. Mulching around the base of plants can help suppress weeds while retaining moisture.
Rhubarb plants benefit from division every few years when overcrowded or less productive. The best time to divide is in early spring before new growth starts or after harvesting in late summer.
While rhubarb is generally resistant to pests and diseases, it’s essential to remain vigilant:
Rhubarb can typically be harvested about 1 year after planting if grown from crowns (2 years if grown from seeds). Wait until the stalks are at least 12 inches long before harvesting.
To harvest rhubarb:
The best time for harvesting rhubarb is from late spring through early summer (May through June). After this period, allow plants to rejuvenate by letting some stalks grow undisturbed.
Preparing your rhubarb plants for winter is crucial in Montana’s cold climate:
