Can You Hear Rhubarb Growing? | Odd Garden Myth Explained

Some gardeners say rhubarb makes soft creaks as stalks push through, but any sound is faint and you’re unlikely to hear growth in real time.

If you’ve heard gardeners joke and wondered, “Can You Hear Rhubarb Growing?” you’re not alone. The phrase pops up in quirky fact lists, social posts, and stories about old forcing sheds in Yorkshire. It sounds like something from a children’s book, yet it has just enough truth behind it to stick in your mind.

This article clears up what people mean when they talk about hearing rhubarb, what science says about plants making sound, and what you can expect in a normal backyard bed. Along the way you’ll pick up practical rhubarb tips, so your patch stays healthy, productive, and safe to harvest.

Can You Hear Rhubarb Growing? Myth Versus Garden Reality

The short version: in special forcing sheds, growers sometimes notice faint pops and creaks as rhubarb shoots rush upward in darkness. In a typical outdoor bed, you will not sit beside a clump and hear a steady soundtrack of growth. Human ears just are not sensitive enough, and the everyday noise around you drowns out tiny movements.

The idea survives because it is memorable and because forced rhubarb grows fast. In the famous Rhubarb Triangle of West Yorkshire, crowns are lifted from the field, chilled, then moved into warm, dark sheds. There, the buds bolt toward faint candlelight, forming pale pink stalks that stretch at a remarkable pace.

Inside those sheds everything is quiet. No birds, no traffic, no radios. When a stalk slides past another stalk, when a leaf unfurls and rubs a neighbor, you can sometimes hear small crackles. That is movement, not some mystical plant voice, yet for visitors it feels magical enough to turn into legend.

What Gardeners Mean When They Talk About Hearing Rhubarb

Growers who spend long hours in forcing sheds describe sounds such as

• Soft pops as cells stretch and stalks shift against each other.
• Gentle squeaks where petioles slide past wooden boards or old leaves.
• Occasional snaps when a brittle leaf vein breaks in the dark.

These are short, irregular noises. You are not listening to a constant hum. Instead, you have long stretches of silence broken now and then by tiny clicks. In a silent shed, at night, with your ears tuned in, those sounds stand out. In a breezy backyard with birds singing and cars passing by, the same tiny movements vanish under background noise.

What Science Says About Plants Making Sound

In recent years, plant biologists have started to measure sound from stems and leaves with sensitive microphones. One research group recorded ultrasonic clicks from tomato and tobacco plants under drought and cutting stress. These sounds sit far above the range of human hearing but can be picked up by devices and even some insects.

That research shows that plants do emit sound under strain. It does not mean you can sit on a stool and hear a chorus of screams from your rhubarb bed. The clicks in the studies were ultrasonic and needed special equipment, and the work focused on other crops. Rhubarb is not silent, yet most of its acoustic life happens outside your ears’ range.

Hearing Rhubarb Growing In Your Garden: What You Might Notice

If you pull up a chair beside a clump on a normal day, you will not hear stalks racing upward. Still, there are a few sounds around a patch that people sometimes blame on growth.

• Rustling leaves. Large leaves catch small gusts of wind and scrape each other, which can sound like quiet shuffling.
• Dripping and soil shifts. After watering or rain, droplets fall from leaves and patter on mulch, or soil settles slightly around the crown.
• Insect activity. Beetles or slugs moving under old leaves can make faint crackling noises, especially on dry mulch.
• Human movement. When you bend stalks to inspect them, you may hear creaks as tissues flex. That is you, not spontaneous motion.

All of this can be charming, but it is not proof that you can casually hear rhubarb lengthen in real time. Instead, treat the phrase “hear rhubarb grow” as shorthand for spending quiet, attentive time near a rapidly changing plant.

How Rhubarb Actually Grows And Why It Seems So Fast

Rhubarb is a hardy perennial grown from crowns or divisions. Once established, each plant wakes early in spring, sending up thick red or green stalks and big leaves from a central crown. Cool weather suits it, so that early surge often feels dramatic after a long winter.

In outdoor beds, roots store energy during the growing season. As soil warms, that stored energy fuels rapid bud expansion. Stalks stretch as cells fill with water and expand. Under forcing conditions, warmth and darkness remove many limits, so growth in the shed can speed up and look almost unreal.

Good care magnifies that effect. A healthy crown with rich soil, steady moisture, and enough chill over winter will push out thick stalks that look bigger each day. Even if you never hear a pop, you will see clear changes from morning to evening during the peak flush.

For most home growers, the main payoff is not sound but reliable harvests. Once you understand what rhubarb needs, the plant turns into a steady spring staple.

Practical Rhubarb Care So Your Patch Thrives

Plant health shapes growth speed and the feel of your patch, whether you ever step into a forcing shed or not. Guidance from university extension horticulture teams gives a clear pattern: choose a good site, plant at the right depth, feed and water properly, then harvest with a light hand in the early years.

Planting And Site Choice

Rhubarb likes full sun in cool regions and light afternoon shade where summers run hot. Soil should drain well yet hold moisture, with plenty of organic matter mixed in. A practical rule from the growing rhubarb guide from University of Minnesota Extension is to plant crowns so that the buds sit 1 to 2 inches below the surface, spaced 3 to 4 feet apart in each direction.

A bed that floods after rain does not suit this crop. Crowns can rot in standing water. Raised beds or higher ground give roots air space and help the plant settle in for the long term.

Watering And Feeding

Like many perennial vegetables, rhubarb enjoys steady moisture rather than wild swings between drought and saturation. Deep watering once or twice a week in dry weather usually beats light, daily sprinkles. Mulch around the crowns with straw, shredded leaves, or composted bark to keep the soil from drying out fast.

At the start of spring growth, spread a layer of compost or a balanced granular fertilizer around each plant. That top dressing refreshes nutrients without burning stalks. Avoid piling material directly on the crown itself; leave the bud area just visible.

Harvesting Without Hurting The Plant

Rhubarb needs time to build root reserves. Many extension sources suggest skipping harvest in the first year after planting and taking only a light picking in the second year. From the third season onward, you can gather more stalks, stopping when stems thin out later in summer.

Harvest by sliding your hand down the stalk, tugging gently, and giving a twist at the base. That motion pops the stalk free without leaving stubs that invite rot. Always leave at least a third of the stalks on the plant so it can keep producing.

Is Any Of This Dangerous? Rhubarb Safety Basics

While this topic starts with a fun sound myth, there is a safety angle you should know well: rhubarb leaves are poisonous to people and pets. Stems are the edible part. Leaves contain oxalic acid and other substances that can cause stomach distress and other symptoms if eaten in large quantity.

The Oregon State University Extension service states clearly that rhubarb leaves should never be eaten and that only the stalks belong in pies, crumbles, or sauces. Cut leaves off outside, drop them straight into a compost heap or garden waste bin, and wash your hands after handling big piles of foliage.

Do not worry about trace contact between leaves and neighboring vegetables. During composting, oxalic acid breaks down, and finished compost that once contained leaves can be spread back onto beds without harm.

Why The Rhubarb Triangle And Forcing Sheds Fascinate People

Part of the charm behind the question “Can You Hear Rhubarb Growing?” comes from a very specific place. In northern England, a small region between a few towns became famous for winter forced rhubarb, now protected under European food name rules. Crowns grow outside for two years, then move into dark sheds for their final push.

Inside those sheds, workers harvest by candlelight so stalks are not shocked by sudden brightness. The hush, the pink glow, and the rapid stretch of stalks make the setting feel almost theatrical. Stories about night harvests, faint plant sounds, and decades of family skill all feed into the modern myth.

If you ever tour such a shed, you might notice a few faint ticks from stalks. For many visitors, that tiny sensory detail becomes the line they share later: “You can even hear it grow.”

How Plant Sound Research Connects To The Rhubarb Story

The sound idea no longer belongs only to folklore and shed tales. Recent work in plant bioacoustics records tiny pops from stems that are under stress. In one study, tomato and tobacco plants under drought or cutting stress emitted ultrasonic clicks that microphones could detect from several feet away.

Separate research has shown that some insects can pick up those ultrasonic signals and use them while choosing where to lay eggs. That means plants and insects can “talk” through sound that humans never hear. Rhubarb has not been tested in the same way yet, yet it is reasonable to guess that its stalks make similar microscopic noises when tissues stretch, freeze, or dry.

This science gives a neat bridge between lab benches and the romantic picture of forced sheds. Growers hear occasional audible creaks in special conditions. Instruments reveal that plants under stress produce even more sound outside the human range. Both views point toward one conclusion: plants are far less quiet than they look, though our ears catch only a small part of the story.

If you want to dig deeper into this topic, look for studies on ultrasonic emissions from stressed plants in peer-reviewed journals and summary articles that explain the methods in plain language. Those sources lay out the microphones, distances, and statistical checks used, which keeps the conversation grounded in measured data rather than tall tales.

So, Can You Hear Rhubarb Growing Or Not?

In an ordinary backyard bed, you will not sit beside a rhubarb clump and hear a constant soundtrack of growth. The stalks move slowly, your ears have limits, and neighborhood noise covers tiny creaks. What you will notice instead is a plant that looks larger each day, with leaves that go from tight rolls to broad umbrellas in a short span of cool weeks.

In dark forcing sheds, in silence, with strong growth and careful attention, growers sometimes catch faint pops as stalks slide and stretch. That rare experience sparked the phrase “you can hear rhubarb grow,” which then spread far beyond Yorkshire. Add in the new wave of lab research on plant sound and the myth starts to look more like an exaggerated version of a small nugget of truth.

If the story makes you smile and nudges you to plant a crown or two, that is the best result. Give your rhubarb a good site, treat the leaves with respect, harvest stalks with care, and whether or not you hear a single creak, you’ll still enjoy the sight of those bold spring stems returning year after year.
