When to Plant Rhubarb Crowns

Best Planting Time

Rhubarb crowns should ideally be planted in the spring as soon as the soil is workable. However, fall planting is also possible in some regions. Here’s a breakdown:

• Spring Planting: In most areas, spring is the preferred time to plant. Aim for late March to early May, depending on your local climate.
• Fall Planting: In milder climates, you can plant rhubarb crowns in late summer to early fall. This allows the plants to establish roots before winter.

Consider Your Climate

Understanding your hardiness zone can help you determine the best time for planting. Rhubarb grows well in USDA zones 3-8.

Preparing the Planting Site

Selecting the Right Location

1. Sunlight: Rhubarb thrives in full sun (6-8 hours of sunlight daily), but it can tolerate partial shade.
2. Soil: Rhubarb prefers well-draining, loamy soil that is rich in organic matter.
3. Space: Ensure there’s adequate space for growth; rhubarb plants can spread quite wide (about 3 feet).

Soil Preparation

1. Testing Soil: Test your soil pH; rhubarb grows best in slightly acidic to neutral soil (pH 6.0-7.0).
2. Amending Soil: Incorporate compost or well-rotted manure to improve fertility and drainage.
3. Tilling: Loosen the soil to a depth of at least 12 inches to promote root penetration.

Planting Rhubarb Crowns

Step-by-Step Planting Guide

1. Digging the Hole:

• Dig a hole that is about 12-18 inches deep and wide enough to accommodate the crown comfortably.

1. Positioning the Crown:

• Place the rhubarb crown in the hole with the buds facing upward. Cover it with 1-2 inches of soil.

1. Backfilling:

• Fill in around the crown, gently patting the soil down to eliminate air pockets.

1. Watering:

• Water thoroughly after planting to help settle the soil and hydrate the crown.

1. Mulching:

• Apply a layer of mulch (such as straw or wood chips) to help retain moisture and suppress weeds.

Caring for Your Rhubarb Plants

Watering Practices

• Regular Watering: Keep the soil consistently moist, especially during the first year of establishment. Avoid waterlogging.
• Deep Watering: Aim for deep watering sessions, approximately once a week, depending on rainfall and temperature.

Fertilizing Rhubarb

1. First Year:

• Avoid fertilizing until the second year to allow the plant to establish roots.

1. Subsequent Years:

• In early spring, apply a balanced fertilizer (10-10-10 NPK) or compost to promote vigorous growth.

Mulching Benefits

• Moisture Retention: Mulch helps retain soil moisture, preventing weeds from competing for nutrients.
• Temperature Regulation: Mulch insulates the soil, keeping roots cool in summer and warm in winter.

Fertilizing and Mulching

Fertilizing Rhubarb

1. Early Spring Fertilization:

• Apply a balanced fertilizer in early spring before the growth season begins. An organic option like compost is also beneficial.

1. Follow-Up Fertilization:

• After the first year, apply fertilizer again mid-summer to support new growth and fruit production.

Mulching Rhubarb

1. Application:

• Apply a thick layer of organic mulch, such as straw or shredded leaves, around the base of the plants to maintain moisture levels and suppress weeds.

1. Benefits of Mulch:

• Helps regulate soil temperature, improves soil structure as it decomposes, and provides a habitat for beneficial organisms.

Pest and Disease Management

Common Pests

1. Rhubarb Weevils:

• Description: These pests can damage crowns and stems, leading to stunted growth.
• Control: Handpick pests and apply organic insecticides as needed.

1. Aphids:

• Description: Small sap-sucking insects that can weaken plants.
• Control: Use insecticidal soap or introduce beneficial insects like ladybugs.

1. Crown Rot:

• Description: Fungal disease that causes decay at the base of the plant.
• Control: Ensure proper drainage and avoid overcrowding plants.

Common Diseases

1. Powdery Mildew:

• Description: A fungal disease characterized by white powdery spots on leaves.
• Prevention: Ensure good air circulation and avoid overhead watering.

1. Leaf Spot:

• Description: Fungal infections that cause dark spots on leaves.
• Prevention: Remove infected leaves and maintain proper plant spacing.

Harvesting Rhubarb

When to Harvest

1. Timing:

• Rhubarb stalks are typically ready to harvest in late spring to early summer, usually around 8-12 weeks after planting.

1. Signs of Ripeness:

• Harvest when the stalks are at least 12 inches long and firm to the touch. The color should be vibrant, ranging from green to deep red depending on the variety.

How to Harvest

1. Cutting Stalks:

• Use a sharp knife or garden shears to cut the stalks at the base, being careful not to damage the crown.

1. Leave Some Stalks:

• Always leave at least one-third of the stalks on the plant to ensure it continues to grow and thrive.

Storing Rhubarb

1. Refrigeration:

• Store harvested rhubarb in the refrigerator wrapped in a damp cloth or in a plastic bag for up to two weeks.

1. Freezing:

• Chop rhubarb into pieces

, blanch for a few minutes, then cool in ice water before freezing in airtight containers.

Winterizing Rhubarb Plants

Preparing for Winter

1. Mulching:

• Apply a thick layer of mulch in late fall to protect the crowns from harsh winter temperatures.

1. Pruning:

• Cut back any dead or diseased foliage in late fall to prevent disease and pests from overwintering.

Protecting Against Frost

1. Covering:

• In regions with extreme cold, consider covering the crowns with burlap or frost cloth to provide additional insulation.

1. Monitoring Soil Moisture:

• Ensure the soil remains slightly moist during winter, but avoid overwatering to prevent crown rot.

Common Mistakes to Avoid

Overwatering

• Issue: Excess moisture can lead to root rot and other diseases.
• Solution: Ensure good drainage and allow the soil to dry slightly between watering sessions.

Poor Soil Preparation

• Issue: Inadequate soil amendments can lead to nutrient deficiencies and stunted growth.
• Solution: Always test and amend soil before planting to create an ideal growing environment.

Neglecting Fertilization

• Issue: Failure to fertilize can result in poor growth and reduced yields.
• Solution: Follow a regular fertilization schedule, especially in the early years of growth.

Ignoring Pest Control

• Issue: Early signs of pests or diseases can quickly escalate if not addressed.
• Solution: Monitor plants regularly and implement preventive measures as needed.
