Seeded extensive green roof

When to specify...

Seeding an extensive green roof can be an economical and practical method of greening very large areas. The mix of seeds, carrier, tackifier and fertiliser may be sown across the surface either by hand or machine. Plant establishment and full coverage will take between 18-24 months to achieve, depending upon the time of year sowing takes place and the weather conditions during the period of establishment.
