  • Biodiverse Substrate

    Biodiverse substrate is suitable for Brown and Biodiverse roofs that are to be blanket covered, seeded or plug planted. The balance of water-absorbent mineral, impervious material (allowing for free drainage) and low-nutrient organic material provides the optimum growing medium for a sustainable, long-term wildflower habitat. BD3 substrate is ideal for use with Verdant Blanket native wild plant seed, plug and blanket products.

It has been developed, tested and approved in line with the FLL standards for green roof growing media to give the right balance of moisture retention and drainage free.                  The substrate also contains the right balance of nutrients –enough to keep the plants healthy without fertiliser but not too rich so as to stimulate excess growth.
