How to Grow Rhubarb from Seed at Home

1. Choosing the Right Rhubarb Variety:

Rhubarb comes in various varieties, each with its own characteristics, flavor profiles, and colors. Here are some popular rhubarb varieties to consider:

• Victoria: This classic variety features greenish-red stalks and is known for its reliability and vigorous growth.

• Crimson Cherry: As the name suggests, this variety boasts deep red stalks and offers a sweeter flavor compared to traditional rhubarb.

• Canada Red: With strikingly red stalks and a robust flavor, Canada Red is a favorite for both culinary and ornamental purposes.

• Timperley Early: If you’re looking for an early-harvest variety, Timperley Early produces pinkish-green stalks and has a milder taste.

Select a variety based on your taste preferences, climate, and available space in your garden. Rhubarb is a hardy plant, and with the right care, it can thrive in various environments.

2. Preparing the Planting Site:

Creating an optimal environment for rhubarb is crucial for its long-term success. Follow these steps when preparing the planting site:

• Sunlight Requirements: Choose a location that receives full to partial sunlight. Rhubarb prefers at least six hours of sunlight per day for robust growth.

• Soil Preparation: Rhubarb thrives in well-drained, fertile soil with a pH level between 6.0 and 6.8. Amend the soil with organic matter, such as compost or well-rotted manure, to improve fertility.

• Spacing: Plant rhubarb crowns (the root portion of the plant) about 3 to 4 feet apart to allow for their expansive growth.

3. Planting Rhubarb Crowns:

Rhubarb is typically propagated using crowns, which are sections of the plant’s root system. Follow these steps for successful planting:

• Timing: Plant rhubarb crowns in early spring or late fall when the plant is dormant.

• Crown Placement: Dig a hole large enough to accommodate the crown’s root system. Place the crown with the buds facing upward, and cover it with soil, leaving the upper portion exposed.

• Watering: Water the newly planted crowns thoroughly to settle the soil. Continue to keep the soil consistently moist during the initial establishment period.

4. Caring for Rhubarb Plants:

Proper care is essential for ensuring healthy rhubarb plants and a bountiful harvest. Here’s how to care for your rhubarb throughout the growing season:

• Watering: Rhubarb prefers consistently moist soil. Water the plants regularly, especially during dry spells. Avoid waterlogged conditions, as rhubarb roots can be sensitive to excessive moisture.

• Mulching: Apply a layer of mulch around the plants to retain soil moisture, suppress weeds, and regulate soil temperature.

• Fertilization: In early spring, apply a balanced fertilizer or well-rotted compost around the rhubarb plants. Avoid high-nitrogen fertilizers, as excessive nitrogen can lead to soft stalks.

• Dividing Rhubarb: Rhubarb plants benefit from division every 4-5 years to maintain vigor. Lift and divide the crowns in late fall or early spring, replanting the sections with healthy buds.

5. Harvesting Rhubarb Stalks:

Patience is key when it comes to harvesting rhubarb. Allow the plants to establish themselves before harvesting the stalks. Follow these guidelines for a successful harvest:

• First-Year Harvest: Refrain from harvesting any stalks during the first year to allow the plant to build strong roots and reserves.

• Second-Year Harvest: In the second year, you can harvest a few stalks, but avoid overharvesting. Gradually increase the harvest in subsequent years.

• Harvesting Technique: To harvest rhubarb, grasp the stalk near the base and pull it away from the plant with a gentle, twisting motion. Avoid cutting the stalks, as this can leave behind a portion that may rot and harm the plant.

• Stalk Size: Harvest stalks that are at least 10 to 12 inches long. Smaller stalks are an indication that the plant is still establishing itself.

6. Common Rhubarb Pests and Diseases:

While rhubarb is relatively resistant to pests and diseases, keeping an eye out for potential issues is essential. Here are some common problems and preventive measures:

• Crown Rot: Avoid planting rhubarb in waterlogged soil, as this can lead to crown rot. Ensure proper drainage to prevent this issue.

• Aphids: Keep an eye out for aphids, especially on the underside of leaves. A strong spray of water or insecticidal soap can help control aphid infestations.

• Leaf Spot Diseases: Maintain good air circulation by spacing plants adequately. Remove and destroy any affected leaves to prevent the spread of leaf spot diseases.

7. Storing and Enjoying Rhubarb:

Once you’ve harvested your rhubarb, it’s time to savor its unique flavor in a variety of culinary creations. Here are some tips for storing and using rhubarb:

• Refrigeration: Fresh rhubarb can be stored in the refrigerator for up to two weeks. Trim the leaves and store the stalks in a plastic bag.

• Freezing: If you have an abundance of rhubarb, consider freezing it for later use. Clean and chop the stalks before freezing, and use them in pies, jams, or sauces.

• Culinary Uses: Rhubarb is a versatile ingredient that can be used in both sweet and savory dishes. From classic rhubarb pie to compotes, jams, and even savory sauces, let your culinary creativity shine.
