Did You Know That Plants Go Dormant?

Perennial plants, like hibernating bears, make the most of winter as a vital time for rejuvenation. Dormancy serves as a survival strategy, enabling your garden to conserve energy during harsh weather – even if it seems inactive on the surface. In this article, we look into how plants utilize this period conserve energy until more favorable growing conditions arise.

What is Dormancy?

Dormancy is a natural cycle observed in all living organisms. For humans, it manifests as the urge to sleep each night, signaling a need for rest. In plants, dormancy is a response to environmental cues such as freezing temperatures, drought, or limited water and nutrients. Rather than expending energy on growth, plants enter a state of dormancy to conserve resources until favorable conditions return. This pause in growth allows the plant’s roots to continue developing and thriving.

Cue to Dormancy

Plants, much like humans, are profoundly influenced by temperature and sunlight, which act as signals indicating the onset of winter. As autumn progresses, the days grow shorter, leading to an earlier onset of darkness. Consequently, we find ourselves feeling sleepy earlier than usual. For plants, this reduction in daylight triggers a slowdown in growth, marking the beginning of the dormancy phase. The extended periods of darkness and cooler temperatures during this time clearly communicate to your garden that winter is approaching.

If plants were to continue growing actively during winter, the water stored in their stems, leaves, and trunks would freeze, causing damage. This is particularly evident in trees when an early freeze occurs before they have acclimatized; the outer layers of the bark can suffer damage due to the expansion of freezing water. The cold season also reduces sunlight and freezes the ground, making water scarce and difficult for plants to access.

Post Dormancy

Spring will eventually arrive, bringing shorter nights and more sunlight, which encourages perennials to resume growth. However, they may not immediately spring up at the first sign of spring – depending on your climate, it could take weeks for your garden to emerge from dormancy. Trimming back foliage can promote new growth, but many outdoor plants require minimal maintenance.

However, there is a risk of plants breaking dormancy prematurely. Surprise warm spells can trigger new growth, which may be cut short when temperatures drop again. Therefore, it’s wise to keep your ground covered with mulch to help protect against the dramatic shifts in weather that cause these thaw-freeze cycles.

Being Wise

To become the best gardener possible, understanding the inner workings of your plants is invaluable. Much like us, they are living beings capable of enduring challenging conditions. This is why they can go dormant for an entire season and still thrive later on.

Able to Stop

Consider the most obvious example of winter dormancy: your lawn. Every year, it eventually stops growing and turns brown after prolonged cold. Yet, you can always rely on it to revive (and turn green) when the weather warms up, ready for its regular maintenance once more. Due to the reduced functionality of enzymes driving biochemical reactions in winter, the combination of dropping temperatures and diminished sunlight slows down plants’ metabolism. This leads to a deceleration in photosynthesis and respiration, ultimately halting growth.

What Can You Do in the Meantime?

Crucially, perennials utilize winter dormancy to maintain their internal balance. Similar to how our bodies rejuvenate during sleep, their cell membranes are upheld, and proteins are broken down and reconstructed. However, plants are not as self-sufficient as humans, so they can benefit from our assistance in staying protected. Adding a layer of hay or mulch can retain moisture and warmth, while a plant protection blanket can guard against frost or adverse weather conditions. Whichever method you opt for, be aware that there are numerous ways to prolong your garden’s well-being into the winter months.

Gardens have a remarkable ability to regulate themselves, a fact that is often underestimated. However, during winter dormancy, it doesn’t hurt to take steps to ensure that your garden is thriving as much as possible.
