How Long Can You Pick Rhubarb in Iowa?

Rhubarb, a perennial plant prized for its tart, flavorful stalks, is widely cultivated in Iowa. Its popularity stems from its versatility in culinary applications, ranging from pies and tarts to sauces and preserves. To ensure a bountiful harvest, proper picking techniques are crucial. This article delves into the intricacies of rhubarb picking in Iowa, covering topics such as ideal growing conditions, harvesting timeline, and storage methods.

Rhubarb Varieties in Iowa

Iowa’s climate and soil conditions favor the cultivation of several rhubarb varieties, each with distinct characteristics and taste profiles. Some popular varieties include:

• ‘Victoria’: Known for its large, crimson-red stalks, ‘Victoria’ is a reliable and productive variety.
• ‘Canada Red’: This variety produces vibrant red stalks with a slightly sweeter flavor compared to other cultivars.
• ‘MacDonald’: ‘MacDonald’ is valued for its tender, flavorful stalks and is often used in pies and other desserts.
• ‘Valentine’: With its bright red stalks and mild tartness, ‘Valentine’ is a favorite among home gardeners.

Ideal Growing Conditions

Rhubarb thrives in well-drained, fertile soils rich in organic matter. It prefers full sun exposure but can tolerate partial shade. The ideal soil pH range for rhubarb is between 6.0 and 6.8. In Iowa’s climate, rhubarb is typically planted in the spring or fall.

Rhubarb Planting and Care

To ensure successful rhubarb cultivation, proper planting and care are essential. Before planting, prepare the soil by tilling and adding compost or well-rotted manure to improve soil structure and fertility. Space rhubarb plants approximately 3 feet apart to allow adequate room for growth. Water regularly, especially during dry spells, and apply a balanced fertilizer in the spring to promote healthy growth.

Rhubarb Harvesting Timeline

The rhubarb harvesting season in Iowa typically begins in late spring or early summer, around April or May. The exact timing can vary depending on weather conditions and the specific variety grown. Harvesting should continue for eight to ten weeks, ending in mid-June. It’s important to monitor the plant’s readiness for picking, as harvesting prematurely can compromise the plant’s health and future yields.

Picking Rhubarb

To harvest rhubarb, grasp the base of the stalk near the ground and pull upward with a slight twisting motion. Alternatively, use a sharp knife or scissors to cut the stalk at the soil line. Avoid pulling or tearing the stalk, as this can damage the plant. Select mature stalks that are at least 10 to 15 inches long and have a firm texture.

Storing and Preserving Rhubarb

Freshly picked rhubarb can be stored in a plastic bag in the refrigerator for up to two weeks. For longer storage, rhubarb can be frozen, canned, or dried. Freezing is a convenient option, as it preserves the rhubarb’s flavor and texture well. To freeze rhubarb, cut the stalks into 1-inch pieces and place them in freezer bags.

Common Rhubarb Picking Mistakes

To ensure a healthy rhubarb plant and a bountiful harvest, avoid these common mistakes:

• Over-harvesting: Avoid harvesting more than one-third of the stalks from a single plant at a time. Excessive harvesting can weaken the plant and reduce future yields.
• Harvesting immature stalks: Only harvest mature stalks that are at least 10 to 15 inches long. Harvesting immature stalks can compromise the plant’s health and lead to poor-quality rhubarb.
• Neglecting plant care: Rhubarb requires regular watering, fertilization, and pest control to thrive. Neglecting these aspects can result in a decline in plant vigor and reduced yields.
