Discover the Secrets of How to Plant Rhubarb Crowns: Expert Advice for Growing Your Own Delicious Rhubarb

Rhubarb, with its vibrant stalks and tart flavor, is a beloved ingredient for pies, crumbles, and jams. But before you can enjoy those delicious treats, you need to know how to plant rhubarb crowns. This guide will walk you through the process, from selecting the right crown to ensuring a bountiful harvest.

Choosing the Right Rhubarb Crown

The foundation of a successful rhubarb patch lies in selecting a healthy crown. Look for these key characteristics:

• Size: Opt for crowns with a minimum of three buds, indicating vigorous growth potential.
• Firmness: The crown should feel firm and solid, free from any soft spots or signs of decay.
• Color: A healthy crown will have a vibrant, reddish-brown color. Avoid crowns with any discoloration or mold.
• Roots: Ensure the roots are well-developed and not dry or brittle.

Preparing the Planting Site

Rhubarb thrives in well-drained soil with ample sunlight. Here’s how to prepare the ideal planting site:

• Location: Choose a spot that receives at least 6 hours of direct sunlight daily.
• Soil: Rhubarb prefers rich, fertile soil with a pH between 6.0 and 6.5. Amend heavy clay soil with compost or peat moss to improve drainage.
• Spacing: Allow 3-4 feet between crowns to ensure adequate space for growth.

Planting Rhubarb Crowns

Timing: The best time to plant rhubarb crowns is in the early spring, before the soil warms up too much. However, you can also plant in late summer or early fall in milder climates.

Planting Process:

1. Dig a hole: Dig a hole twice as wide as the root ball and about 12 inches deep.
2. Amend the soil: Mix some compost or aged manure into the bottom of the hole to provide nutrients.
3. Position the crown: Place the crown in the hole with the buds facing upwards.
4. Backfill the hole: Gently fill the hole with soil, ensuring the crown is level with the ground.
5. Water thoroughly: Water the crown deeply to settle the soil and promote root establishment.

Caring for Your Rhubarb Patch

Once planted, your rhubarb crowns need regular care to thrive.

• Watering: Water your rhubarb regularly, especially during dry periods. Aim for 1-2 inches of water per week.
• Fertilizing: Apply a balanced fertilizer in early spring to provide essential nutrients. You can also use compost or manure as a natural fertilizer.
• Mulching: Apply a layer of organic mulch around the crowns to retain moisture and suppress weeds.
• Weed control: Keep the area around your rhubarb crowns weed-free to prevent competition for nutrients and water.

Harvesting Your Rhubarb

Rhubarb is typically ready for harvest in the second year after planting.

• Timing: Harvest rhubarb stalks in the spring, before the plant starts to flower.
• Harvesting technique: Cut the stalks about 1-2 inches above ground level, leaving some leaves on the plant for photosynthesis.
• Rotation: Harvest stalks from different crowns each year to allow for regrowth.

Protecting Your Rhubarb

Rhubarb can be susceptible to certain pests and diseases.

• Pests: Common pests include aphids, slugs, and snails. Control them with organic methods such as diatomaceous earth or insecticidal soap.
• Diseases: Rhubarb is vulnerable to crown rot, leaf spot, and rust. Good sanitation practices, such as removing infected leaves and debris, can help prevent these diseases.

Rhubarb Beyond the Garden

Once you’ve harvested your rhubarb, there are countless ways to enjoy its tart flavor.

• Culinary uses: Rhubarb is a versatile ingredient for pies, crumbles, jams, sauces, and even chutneys.
• Preserving: You can preserve rhubarb by freezing, canning, or making jams and jellies.
• Medicinal properties: Rhubarb has been used in traditional medicine for its laxative and digestive properties.
