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 Bauder Flora Seed Mixes are specifically designed for sowing at roof level they contain tackifier and fertiliser with the seed to insure the seed is stuck to the substrate and not blown of washed off the roof, this insures the highest germination rates. To meet particular planting requirements on Biodiverse roofs seeding is often combined with plug planting to get an exact species mix.
