Rhubarb Not Growing: Troubleshooting and Solutions

Introduction

Rhubarb is a hardy and low-maintenance perennial plant that thrives in most gardens, but sometimes it doesn’t grow as expected. Issues like poor growth, small or thin stalks, or an overall unhealthy appearance can frustrate even the most experienced gardeners. Fortunately, most problems with rhubarb can be resolved with a bit of troubleshooting and care.

This guide will explore the common reasons why rhubarb might not be growing well and provide actionable solutions to get your plants back on track for a healthy and productive harvest.

Common Reasons Why Rhubarb Isn’t Growing

1. Poor Soil Conditions

• Problem: Rhubarb requires rich, well-draining soil to thrive. If the soil is too compacted, waterlogged, or nutrient-poor, the plant may struggle to grow.
• Solution:
  • Test your soil’s pH and aim for a range of 6.0-7.0.
  • Improve the soil by adding organic matter, such as compost or well-rotted manure.
  • Ensure good drainage to prevent waterlogging.

2. Overcrowding

• Problem: Mature rhubarb plants can become overcrowded, leading to competition for nutrients and stunted growth.
• Solution:
  • Divide the crowns every 5-7 years in early spring or autumn to rejuvenate the plant.
  • Replant divisions with enough space (3-4 feet apart) for proper growth.

3. Insufficient Sunlight

• Problem: Rhubarb needs full sun to grow well. If it’s planted in a shaded area, growth may be slow or weak.
• Solution:
  • Transplant the rhubarb to a sunnier location.
  • Ensure the new spot receives at least 6-8 hours of direct sunlight daily.

4. Underwatering or Overwatering

• Problem: Both underwatering and overwatering can stress the plant and hinder growth.
• Solution:

  • Avoid overwatering and ensure the crown is planted just above soil level.

8. Planting Too Deep

• Problem: If the crown is planted too deep, it may struggle to grow or produce healthy stalks.
• Solution:
  • Ensure the crown is planted with the buds just above the soil surface.

9. Age of the Plant

• Problem: Older rhubarb plants may become less productive over time.
• Solution:
  • Divide and replant older rhubarb crowns to rejuvenate growth.
  • Consider planting new crowns every 5-7 years to maintain productivity.

10. Pests and Diseases

• Problem: Pests like slugs and snails or diseases like leaf spot can weaken the plant.
• Solution:
  • Remove slugs and snails manually or use organic slug deterrents.

• Sow seeds indoors in early spring or directly outdoors after the last frost.

How to Plant Rhubarb Plants

1. Planting Bare-Root Crowns

1. Dig a hole large enough to accommodate the crown.
2. Place the crown with the buds facing upward, just above the soil surface.
3. Backfill with soil and water thoroughly.
4. Space plants 3-4 feet apart to allow for growth.

2. Planting Potted Rhubarb Plants

• Dig a hole twice the size of the root ball.
• Place the plant in the hole, ensuring the crown is level with the soil surface.
• Water well after planting.

3. Planting Rhubarb Seeds

1. Sow seeds 1cm deep in pots of seed compost.
2. Keep the compost moist and place pots in a warm, bright location.
3. Transplant seedlings outdoors once they are 10-15cm tall and after the last frost.

Caring for Rhubarb Plants

1. Watering

• Water regularly during dry spells, especially in the first year.
• Avoid waterlogging, as rhubarb dislikes soggy conditions.

2. Mulching

• Apply a thick layer of organic mulch, such as compost or straw, around the base of the plant.
• Mulch retains moisture, suppresses weeds, and provides nutrients.

3. Fertilizing

• Feed rhubarb plants with a balanced fertilizer or well-rotted manure in early spring.
• Avoid over-fertilizing, as it can lead to excessive leaf growth at the expense of stalks.

4. Removing Flower Stalks

• Remove flower stalks as soon as they appear to redirect energy to the edible stalks.

Harvesting Rhubarb

1. When to Harvest:

• Avoid harvesting in the plant’s first year to allow it to establish.
• Harvest from mid-spring to late summer starting in the second year.

2. How to Harvest:

1. Hold the stalk near the base and gently pull with a twisting motion.
2. Alternatively, cut the stalk at the base with a sharp knife.
3. Do not harvest more than one-third of the plant’s stalks at a time to avoid weakening it.

3. Harvesting Tips:

• Only harvest stalks that are 12-18 inches long.
• Rhubarb leaves are toxic and should never be consumed.

Overwintering Rhubarb Plants

• In late autumn, cut back dead leaves and apply a thick layer of mulch over the crown to protect it from frost.
• Forcing rhubarb: Cover the crown with a forcing pot or upturned bucket in late winter to encourage early, tender stalks.

Common Problems with Rhubarb Plants

1. Crown Rot

• Cause: Waterlogged soil or poor drainage.
• Solution: Plant rhubarb in well-draining soil and avoid overwatering.

2. Slugs and Snails

• Cause: Slugs and snails feed on young shoots.
• Solution: Use slug deterrents, traps, or copper tape around the plant.

3. Weak Growth

• Cause: Nutrient deficiency or overcrowding.
• Solution: Feed the plant with a balanced fertilizer and divide overcrowded crowns.

4. Yellow Leaves

• Cause: Overwatering, poor drainage, or nutrient deficiency.
• Solution: Improve soil drainage and adjust watering and fertilizing practices.
