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. Turgor Pressure

• As cells expand during growth, internal water pressure creates tension that can produce creaking or popping noises.

2. Stress on Structures

• Rapid growth in confined spaces increases mechanical stress on stalks and leaves, amplifying sounds.

3. Environmental Interactions

• External factors like wind and temperature changes can contribute to leaf rustling and other sounds.

Benefits of Rhubarb Forcing (and Its Sounds)

While the growing sounds are fascinating, forcing rhubarb also has practical benefits:

1. Sweeter Stalks: Forced rhubarb is sweeter and less fibrous than naturally grown stalks.
2. Early Harvest: Forcing allows you to enjoy rhubarb stalks weeks earlier than outdoor growth.
3. Unique Experience: The sound of growing rhubarb adds a unique sensory element to gardening.

How to Force Rhubarb

If you want to force rhubarb and experience the growing sounds, follow these steps:

1. Choose a Healthy Crown

• Select a well-established rhubarb plant, ideally three years old or older.

2. Cover the Crown

• In late winter, place a forcing pot, bucket, or upturned bin over the crown. Ensure no light enters.

3. Insulate the Pot

• Cover the pot with straw or mulch to keep the temperature consistent.

4. Monitor Growth

• Check weekly for growth. Forced stalks are ready to harvest when they are about 12-18 inches tall.

5. Harvest Gently

• Twist and pull stalks from the base to harvest without damaging the crown.

FAQs About Rhubarb Growing Sounds

1. Can you really hear rhubarb grow?

• Yes, especially during forcing or rapid spring growth, you can hear subtle creaks, pops, and rustling sounds.

2. Why does rhubarb make noises during forcing?

• The stalks grow rapidly in confined spaces, creating pressure that produces creaks and pops.

3. Is forced rhubarb healthier than naturally grown rhubarb?

• Both are healthy, but forced rhubarb tends to be sweeter and more tender due to reduced fiber.

4. Does rhubarb make sounds when grown outdoors?

• Yes, but the sounds are less noticeable and typically occur during rapid growth or windy conditions.

5. Can I force rhubarb without a forcing pot?

• Yes, you can use an upturned bucket, bin, or even a cardboard box as long as it blocks light.

6. Is forcing rhubarb harmful to the plant?

• No, forcing stimulates early growth but should only be done every few years to allow the crown to recover.

7. What time of year can I hear rhubarb growing?

• Late winter and early spring are the best times, particularly during forcing.

8. Can I hear rhubarb growing at night?

• Yes, nighttime is often the quietest time to detect subtle rhubarb sounds.

9. Does rhubarb make sounds indoors?

• Yes, rhubarb forced indoors or in sheds often produces louder creaking and popping sounds.

10. How long does forced rhubarb take to grow?

• Forced rhubarb typically takes 6-8 weeks to grow to harvestable size.

Fun Facts About Rhubarb and Its Growing Sounds

1. Yorkshire Tradition: In Yorkshire’s “Rhubarb Triangle,” forced rhubarb is grown in dark sheds, and the growing sounds are celebrated as part of the process.
2. Rapid Growth: Forced rhubarb can grow up to 2 inches per day, contributing to the audible creaking and popping sounds.
3. Historical Delight: Victorian gardeners were fascinated by the sounds of forced rhubarb and often demonstrated it to guests.

Conclusion

The sound of rhubarb growing is a fascinating and unique phenomenon that adds a sensory dimension to gardening. Whether you’re forcing rhubarb in pots or observing its natural growth in spring, these subtle noises are a testament to the plant’s rapid development. By creating the right conditions, you can experience the wonders of rhubarb growing sounds while enjoying sweet, tender stalks for your recipes.
