Rhubarb Growing Sound: The Fascinating Phenomenon Explained

Introduction

Rhubarb is not just known for its tangy stalks and vibrant leaves—it also holds a surprising secret: it can make sounds as it grows. This fascinating phenomenon has intrigued gardeners and scientists alike, adding an extra layer of wonder to cultivating this hardy perennial.

In this guide, we’ll explore the causes of rhubarb growing sounds, when and why they occur, and how you can witness this unique event in your own garden.


What is the Rhubarb Growing Sound?

The “rhubarb growing sound” refers to the noises produced by the plant as it grows or when it is being forced for early harvests. These sounds can include:

  • Creaking: As the stalks push against one another or the forcing pot.
  • Popping: When stalks grow rapidly and break through soil or obstacles.
  • Rustling: Caused by the movement of large leaves rubbing against each other.

This sound is most commonly associated with forced rhubarb, a method used to grow sweet, tender stalks in controlled conditions.


When Does Rhubarb Make Sounds?

1. During Forcing

  • Forced rhubarb is grown in dark conditions, often in forcing pots or sheds.
  • As the stalks grow rapidly in search of light, the pressure causes creaks and pops.

2. Rapid Growth Periods

  • In spring, when rhubarb experiences its fastest growth, the plant can make subtle noises as it expands.

3. Windy Conditions

  • Large rhubarb leaves may rustle and creak in the wind, adding to the auditory experience.

Why Does Rhubarb Make Sounds?

The sounds made by rhubarb are a natural byproduct of its rapid growth and structural adjustments.

1. Expansion of Stalks

  • Rhubarb stalks grow quickly, and the pressure from this growth can cause creaking and popping noises.

2. Forcing Pressure

  • When rhubarb is grown in dark, confined spaces, the stalks push against one another or the walls of the forcing pot, producing sounds.

3. Leaf Movement

  • The large, heavy leaves of rhubarb can rub against one another or nearby objects, creating rustling or scraping noises.

How to Hear Rhubarb Growing

If you’re curious to hear rhubarb growing sounds for yourself, here’s how to make it happen:

1. Try Forcing Rhubarb

  • Place a forcing pot or an upturned bucket over the crown in late winter.
  • Check on the stalks weekly, and listen closely for creaks and pops as they grow in the dark.

2. Observe Spring Growth

  • Visit your rhubarb patch early in the morning or late at night when it’s quiet.
  • You might hear faint noises as the stalks expand.

3. Quiet Environments

  • Sounds are more noticeable in quiet, controlled environments, such as forcing sheds.

The Science Behind Rhubarb Growing Sounds

The sounds produced by rhubarb are a result of physical and environmental factors:

  1. Fill seed trays or small pots with a light, well-draining seed-starting mix.
  2. Sow seeds 1cm deep and cover lightly with soil.
  3. Water gently to moisten the soil.
  4. Place trays in a warm location (18-21°C or 65-70°F) with plenty of light.
  5. Keep the soil consistently moist but not waterlogged.

2. Sowing Outdoors

  1. Prepare the soil by loosening it and removing any weeds.
  2. Sow seeds 1cm deep, spaced 6 inches apart in rows.
  3. Water lightly and keep the soil moist.

Germinating Rhubarb Seeds

  • Rhubarb seeds typically germinate within 10-20 days under ideal conditions.
  • Thin out seedlings once they develop their first true leaves, leaving the strongest plants.

Transplanting Rhubarb Seedlings

1. When to Transplant

  • Transplant seedlings when they are 10-15cm tall and after the last frost.

2. Preparing the Site

  • Choose a sunny or partially shaded location with rich, well-draining soil.
  • Amend the soil with compost or well-rotted manure before planting.

3. How to Transplant

  1. Dig a hole large enough to accommodate the seedling’s roots.
  2. Place the seedling in the hole, ensuring the crown is level with the soil surface.
  3. Space seedlings 3-4 feet apart to allow room for growth.
  4. Water thoroughly after transplanting.

Caring for Rhubarb Grown from Seeds

1. Watering

  • Keep the soil consistently moist, especially during the first year.
  • Avoid overwatering to prevent waterlogging.

2. Feeding

  • Apply a balanced fertilizer in early spring to encourage healthy growth.
  • Mulch with organic matter like compost or straw to provide nutrients and retain moisture.

3. Pruning and Maintenance

  • Remove any flower stalks as soon as they appear to focus energy on growing edible stalks.
  • Trim yellowing or dead leaves to improve airflow and reduce disease risk.

4. Overwintering

  • In late autumn, cut back foliage and mulch the crown to protect it from frost.

Harvesting Rhubarb

1. When to Harvest

  • Avoid harvesting rhubarb in its first year to allow the plant to establish.
  • Begin harvesting in the second year, from mid-spring to late summer.

2. How to Harvest

  1. Hold the stalk near the base and gently twist and pull.
  2. Alternatively, use a sharp knife to cut the stalk at the base.
  3. Harvest only one-third of the stalks at a time to prevent stressing the plant.

3. Harvesting Tips

  • Only harvest stalks that are 12-18 inches long.
  • Discard the leaves, as they are toxic due to high oxalic acid content.

Common Problems and Solutions

1. Poor Germination

  • Cause: Seeds not soaked or planted in unfavorable conditions.
