Create or construct a suitable growing bed that is free of weeds, has reasonable texture and structure and can retain moisture. A minimum depth of 75mm of a substrate with some nutrient and moisture holding capacity will be required to support grass growth. A greater depth and/or irrigation may be needed in drier regions.

Seed is best sown in the autumn or spring but can be sown at other times of the year if there is sufficient warmth and moisture. On shallow growing medium irrigation may be needed to maintain establishment through dry periods. The seed must be surface sown: do not incorporate or cover the seed. Bulk up the seed with an inert carrier such as sand to make distribution easier. (more on sowing)
The requirement for aftercare will vary from scheme to scheme. Some will need minimal maintenance, perhaps only occasional tidying cuts for aesthetic reasons. Living roofs with reasonable growing conditions will produce growth that is likely to need annual maintenance for best results. This gardening will involve weeding and mowing along the lines of grassland aftercare.
ER1 is a complete mix composed of 20% native wild flowers and 80% slow growing grasses (by weight). The flower and grass components are also available to order separately: ER1F the flower component may be sown alone where no grasses are required or sown with the grass component EG6 at a reduced rate.
