Harrowden Enviromat fertiliser is a slow release organic sedum feed formulated for healthy and robust plants. This allows maximum benefit for any living green roof.
Sedum fertilisers have a huge range of benefits for green roofing such as biodiversity, insulation, rainwater amelioration, and oxygen production. Although, it does depend on there being a robust, healthy plant layer. Because plants on a green roof are living in a relatively shallow layer of growing medium, they don’t have the same access to water and nutrients as plants at ground level do. It’s important to make sure that these plants are well nourished so that they will be able to withstand summertime droughts and winter frosts.
Used by professionals, each tub covers 65 square metres. Natural Green Roof Feed may be applied at any time of year, but for best results, apply in early spring and again in early summer. For best results follow the instructions provided with the product. We also recommend that the recommended application rate is not exceeded.
