Benefits of sedum fertilisers

Sedum fertilisers offers a wealth of advantages 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 those at ground level. 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.

Professionals use tubs covering 65 square metres. Natural Green Roof Feed may be applied at any time of year. However, for best results, apply in early Spring and again in early Summer. It is recommend you follow the instructions provided with the product, and that the suggested application rates are not exceeded.
