Growing guide

Preparation

Create or construct a suitable growing bed that is free of weeds, has reasonable texture and structure and can retain moisture. A depth of 75 - 150mm or more is best for supporting the widest range of plant species.  Shallow depths (less than 75mm) and  'extensive' growing medium designed for sedums are not usually adequate and will not contain sufficient moisture or nutrients. (more)

Sowing

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)

Aftercare

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.

 

ER1F can be sown on its own onto clean growing medium to create an open flower rich community or combined with a light sowing of 1g/m2 fine grass mixture EG6. To create "turf roof" grassland we recommend mix ER1 which is a premixed combination of  ER1F and EG6

The further addition of 1g /m2 colourful annual wild flower seed mix EC2 will give quick colour and a supply of seeds to colonise bare ground after die back events.
