Long-lasting growth and strong plants
This organic green roof fertiliser has been specially developed to nourish and strengthen sedum and other green roof plants over an extended period. Its balanced formula supports steady, consistent growth, resulting in a lush, densely vegetated roof with a healthy appearance. Enriched with potassium, it increases plant resilience against extreme weather conditions such as drought, intense sunlight and heavy rainfall. This ensures that your green roof remains in top condition throughout the year.
The fertiliser is suitable for both extensive and intensive green roofs. Extensive roofs typically feature various sedum species, herbs, grasses and flowers, while intensive roofs often include perennials, ornamental grasses, shrubs and even small trees. The formula is universally applicable and tailored to the nutritional needs of every green roof type.
This sustainable fertiliser promotes long-term plant vitality, extends the lifespan of the roof and significantly reduces maintenance requirements.
A living green roof full of strength, colour and balance
This natural Organifer fertiliser nourishes sedum and other roof plants from within, ensuring long-lasting vitality and an even, full cover. The potassium-rich formula encourages compact growth and strong root development, helping the vegetation close quickly and eliminating bare patches.
The result is a beautifully green roof that not only pleases the eye but also improves insulation, enhances water retention and extends the lifespan of the roofing membrane.
Stimulates a healthy, vibrant green roof
A well-fed sedum roof is more than just attractive – it becomes a living ecosystem full of colour, pollinators and natural balance. By providing sedum with the right natural nutrients, plants bloom more abundantly and attract bees, butterflies and other beneficial insects. This means your green roof actively contributes to biodiversity and a healthier urban environment.
The gentle, organic composition of this fertiliser is safe for all rooftop life forms. Its formulation respects the natural ecological balance and supports sustainable growth of sedum vegetation. Whether used on an extensive or intensive green roof, this fertiliser keeps your plants strong, vital and environmentally friendly year after year.
Preserving fertility even under challenging conditions
Green roofs are often subject to intensive drainage and usually have a thin substrate layer. This makes it difficult to maintain soil fertility. This specially developed fertiliser addresses that challenge perfectly by supporting nutrient balance and sustaining healthy soil life, even in shallow substrates with regular water runoff. This ensures your green roof stays in top condition all year round.
Additionally, this fertiliser is perfectly suited for periodic maintenance. Whether applied in spring or autumn, it fits seamlessly into any maintenance schedule. With its efficient, slow-release action and balanced composition, it provides your sedum and green roof vegetation with the right boost at the right time – without risk of over-fertilisation or deficiency.
Versatile and efficient nutrition
This green roof fertiliser is suitable for both extensive and intensive roofs. Whether your roof features a low sedum layer or a mixture of ornamental grasses, herbs, perennials, shrubs or small trees, this formula delivers the right balance of nutrients. Its carefully balanced composition nourishes a wide range of plants simultaneously, helping maintain a healthy, diverse and well-rooted green roof.
Thanks to its controlled nutrient release, leaching is minimised. The fertiliser provides a steady supply of nutrients over time, ensuring the plants remain nourished without burdening the environment. The result is lasting vitality with reduced maintenance needs. Not surprisingly, this fertiliser is widely used by professional green roof specialists.
