As winter blankets the landscape in a quilt of frost, lawns and grass areas across the UK enter a transformative phase known as dormancy. Turf dormancy, a natural survival mechanism, protects grass from the rigors of winter. In this blog post, we'll delve into the intricacies of turf dormancy, exploring its purpose and shedding light on what occurs beneath the frosty surface during the colder months. Additionally, we'll touch on the possibility of harvesting and laying new turf during this period, with some considerations for optimal results.

Understanding Turf Dormancy: 

Turf dormancy is a biological strategy where grass slows down its growth and metabolic activities in response to winter's colder temperatures. Triggered by cooling temperatures and the reduced daylight, this dormancy period allows grass to conserve energy and resources during the challenging winter months.

Reasons Behind Dormancy:

• The drop in temperature and shorter days prompts a slowdown in grass metabolism, curbing active growth.
• In colder climates, freezing temperatures can limit water availability to grass roots. Dormancy helps grass conserve water and navigate periods of environmental stress.
• By entering a dormant state, grass reallocates energy away from active growth, and focuses on enduring the elements.

Are there any signs of turf dormancy?

Above the Ground

• You may notice a change of colour as chlorophyll breaks down, transitioning the green into a less vibrant hue.
• The pace of grass growth significantly slows, with blades becoming less active as metabolic processes wind down.

Below the Surface

• Grass roots experience limited growth during winter. Instead, they focus on maintaining existing structures and absorbing available nutrients and water.
• Essential nutrients are stored in the roots, forming a reserve that proves crucial for rapid regrowth when spring arrives.

Harvesting and Laying New Turf During Dormancy

While dormant, turf grass can still be harvested and used to lay new lawns, provided a few considerations are kept in mind.

Limited Foot Traffic

Recognising that dormant grass is in a weakened state, it's advisable to limit foot traffic to prevent damage to both the dormant blades and roots. The turf will start rooting, but it will be a lower process than in warmer seasons.

Optimal Moisture Levels

Although dormant, the soil should not be allowed to become completely dry. Occasional watering may be necessary, especially in regions susceptible to winter drought.

Postponed Fertilisation

Fertilising during dormancy is generally discouraged. Save the fertilisation efforts for the spring when the grass is actively growing and can better utilize nutrients.

Conclusion

All grasses enter the dormancy phase to conserve energy beneath the winter frost. Homeowners and landscapers can embrace the dormancy period and, if necessary, consider harvesting and laying new turf—just tread lightly and let your dormant turf prepare for a vibrant comeback in the upcoming spring.
