Understanding Dormancy

As the days grow shorter and the frost sets in, a fascinating transformation unfolds in your kitchen garden. In a well-deserved rest after a season of growth, many plants slow their pace or enter dormancy—a natural pause, as do many of the soil microbes. This quiet season is not just a survival tactic but a vital part of the lifecycle, ensuring plants are well-prepared for the following season's growth and reproduction.

The Science of Dormancy

Dormancy is a state where plants and soil microbes reduce their growth and metabolic activities in response to shorter daylight hours and cooler temperatures. While not all plants in your kitchen garden go fully dormant, hardy perennial herbs like thyme, mint, and oregano significantly reduce their growth, conserving energy to weather winter. These plants produce high levels of a hormone called abscisic acid (ABA) in their buds during the fall, which keeps them dormant throughout winter.

Tender annuals like basil and cilantro will instead complete their lifecycle once the temperatures drop below their threshold. Bulbs, like hardneck garlic, establish roots in the first part of the cool season, and then experience a necessary dormant period before sprouting.

Mimicking Nature’s Rhythm

Supporting your garden through winter is really about respecting its natural rhythms. Reduce watering and fertilization in early fall to align with their lower metabolic needs, which is not a sign of stagnation but an adaptive mechanism. This adaptation prevents the plant from using up crucial reserves of energy and nutrients when the external environment is not suitable for growth or development.

Pruning and Winter Care

Avoid significantly pruning hardy herbs in the fall and winter to protect against cold damage, but I do recommend removing diseased foliage. Generally speaking, I don’t provide supplemental water except for things growing under season extenders like a cold frame or hoop house.

A Cozy Winter Blanket

A layer of mulch around the base of your perennials acts as an insulator, shielding roots from temperature swings while preserving soil moisture. As it breaks down, it also nourishes the soil, echoing the natural leaf litter that blankets the forest floor. Just be mindful not to overdo it—too much mulch can lead to rot or attract unwanted pests. I cover my raised beds with leaves gathered from the yard. Come early spring, I move any larger or more solid pieces to the compost bin.

The Spring Awakening

As spring approaches, the gentle transition out of dormancy begins. Gradually reintroduce regular watering and fertilization to coax your plants back into active growth. It’s a magical moment when what appears lifeless comes alive again, bursting forth with fresh leaves. It’s also the moment of truth. Plants don’t live forever, so take note of necessary replacements.

Embracing the Pause

Nature knows best, and thankfully, it's generous with knowledge if we pay attention. This winter rest is a quiet season of strength and highlights an intricate balance that plants maintain to survive and thrive in both harsh and forgiving conditions alike. I find this cycle comforting and a good reminder that human beings also benefit from some quality downtime. If you need me, I’ll be cozy under a duvet with one too many pets and a cup of tea.
