GARDEN ROOF "URBAN GARDENING"
The fruit and vegetable garden on the green roof (0-5°)
URBAN GARDENING is a special form of intensive green roof and the GARDEN ROOF and is very much in vogue. What do you need for this? All you need is a small cultivation area and a little creativity. With this system, the green roof is cultivated as a kitchen garden with useful plants such as vegetables and herbs. With a higher system structure of the green roof, it is even possible to use berry bushes and fruit trees.
With URBAN GARDENING, herbs and vegetables can be planted with a basic layer structure of at least 120 mm. We recommend a greater substrate height for berry bushes. This can be up to 400 mm. Drainage is provided by the Drainage and storage board FKD 40, which is suitable for green roofs from 0-5°.
