In the heart of winter, when nature itself seems to hold its breath under the frosty silence, the resilience and beauty of sedum blankets face their toughest challenge. These living, breathing installations, designed to bring a splash of greenery and biodiversity to our urban landscapes, enter a period of dormancy, much like the world around them. Yet, as the days lengthen and the warmth of the sun returns, so too does the vibrant life within these green roofs, promising a renewal of energy and colour.

Sedum blankets, composed of hardy, drought-resistant sedum species, are an excellent choice for green roofing projects, offering both aesthetic appeal and environmental benefits. However, the winter months can be particularly tough on these blankets due to the natural dormancy of the species, alongside challenges related to transportation and establishment in their new environments. During the colder months, sedum plants go dormant, conserving their energy and resources to survive the harsh conditions. This dormancy, while a natural survival mechanism, can often be mistaken for poor health or even death of the plants. Moreover, the transportation of these blankets during winter can add to the stress experienced by the sedum, as they are uprooted from their growing conditions and exposed to the elements during transit​​​​.

Installation during this time is not without its challenges. The sedum requires a period of acclimatisation and recovery, a time when the plants must adjust to their new environment and begin the slow process of rooting and establishing themselves. This period is crucial for the success of the green roof, and it requires patience and understanding from those overseeing the project. The key to a healthy and vibrant sedum roof is ensuring proper drainage and avoiding excess water, as sedums have a strong dislike for soggy conditions​​.

As the weather warms, the true resilience of sedum comes to the forefront. These plants are incredibly drought-tolerant, thriving in conditions where other species might falter. With the arrival of spring, sedum blankets begin to awaken from their dormancy, showing signs of growth and revival. The red foliage, a common sight in winter as a natural response to cold and reduced sunlight, gradually gives way to lush, green expanses as the plants resume their growth cycle​​.
