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.
