For years, the scientific consensus was clear: trees enter a state of dormancy during winter, halting growth until spring’s warm embrace. But a recent finding has challenged this long-held belief, revealing a hidden world beneath the frozen earth.
Lorène marchand, an ecologist at the University of Antwerp, has uncovered evidence that tree roots continue to grow throughout the winter months. This finding, published in the journal Nature Climate Change, has sent ripples through the scientific community, forcing a reevaluation of our understanding of tree biology.
“We know from the above-ground part of trees that growth gradually stops at the end of summer, when the leaves change color and begin to fall,” Marchand explains. “During the winter months, growth comes to a complete standstill, or so we thought. It starts again in March or April, almost simultaneously with the appearance of the frist leaves.These times depend on climate factors, such as the warmth of the spring and the humidity of the autumn.”
What remains less understood is the activity beneath the surface, the intricate network of tree roots. While it’s known that the minuscule root hairs can continue to grow during autumn and winter under adequate warmth, little research has been conducted on the larger woody roots.
Marchand and her team investigated this mystery by analyzing the growth of beech and birch trees in two different locations in Belgium over a two-year period.Every week, they meticulously examined small sections of both the roots and trunks under a microscope.The results were astonishing.
“We saw that cell growth continued in all the roots, actually during the winter months when we expected to see a stop,” Marchand shares. “It turned out that some cells were still growing in all roots of all tree species in all countries, even in winter.”
This groundbreaking discovery has profound implications for our understanding of tree biology, forest ecology, and even climate change. It suggests that trees might potentially be more resilient than previously thought and continue to play an active role in carbon sequestration even during the coldest months of the year.
The Surprising Secret of Winter Root Growth
The world seems to slumber in winter, a blanket of snow muffling the sounds of life. Yet beneath the frozen ground, an unbelievable change is taking place. The roots of trees, while seemingly dormant, are surprisingly active, continuing their growth throughout the cold months.
Lorene Marchand, a postdoctoral researcher at the University of Antwerp, first noticed this phenomenon unexpectedly. “It was a total surprise,” she recounts. “I was looking to see when the growth would stop, but it kept going. That’s why I asked a colleague to take a look – without saying what I thought I saw.he said there was definitely growth. Then I realized it really wasn’t going to stop. Growth dose slow down during the fall, but never stops completely. during the winter the roots continue to grow slowly but steadily.
A Global Phenomenon
What’s even more engaging is the consistency of this winter root growth across different climates. “It was also fascinating to see that root growth rates in autumn are similar in the three countries,” Marchand observes. “We thought that the roots would grow less in cold Norway than in warmer Spain. But the climate apparently has little influence.”
The Fuel for Winter Growth
But where do these roots get the energy to keep growing when leaves, their primary source of food, are long gone? “Some of the nutrients are stored as reserves in the spring and summer,” Marchand explains. “In autumn, a large part of these reserves move to the root system. We therefore assume that part of it is used during the leafless period to support root growth.
Redefining Forest Models
‘We must include the fact that tree roots grow and use reserves differently than expected in models that predict forest growth and carbon storage of forests,” Marchand emphasizes. “It also means that roots that are disturbed, for example by being moved, may be able to recover in the winter so that they are ready for the new season.”
Trees, those majestic giants of the natural world, continue to fascinate us with their resilience and adaptability. While we frequently enough marvel at their towering heights and expansive canopies, there’s a hidden world beneath the surface, teeming with activity. Recent research has shed light on the intriguing growth patterns of woody tree roots, revealing a secret season of expansion that occurs when temperatures drop and leaves fall.
Contrary to common assumptions,tree roots don’t simply lie dormant during the colder months. Studies, such as one published in the journal Nature Ecology and Evolution, have shown that woody tree roots continue to grow throughout autumn and winter.This persistent growth, often overlooked, plays a crucial role in the tree’s overall health and survival.
Understanding this hidden growth pattern offers valuable insights into the complex relationship between trees and their surroundings. It highlights the remarkable ability of trees to adapt and thrive even in challenging conditions.

A Mystery Unveiled
What has driven this revelation? Marchand explains, “We know that tree growth essentially stops when leaves change color and fall in late summer for above-ground parts. We thought the same was true for roots but were incredibly surprised to find continued cell growth in all roots of every tree species during the winter months. This has overturned our understanding of tree biology during this season.

What’s even more engaging is the consistency of this winter root growth across different climates. ”It was also captivating to see that root growth rates in autumn are similar in the three countries,” Marchand observes.”We thought that the roots would grow less in cold Norway than in warmer Spain.
