Abstract
Abstract A garden installation, especially a roof garden installation, comprises a bed defined by a border of hollow edging elements within which are disposed a separating layer, for example of plastics film, which separates the contents of the bed from an underlying support, for example a roof, a drainage layer, for example of expanded clay or aerated concrete, above the separating layer for regulating the watering of the bed, a filter element above the drainage layer and a layer of soil or other substrate material for receiving plants and/or seeds located above the filter element. The installation may have provision for semi-automatic or fully-automatic watering.

Claim 1
Independent Claim
163 words
A garden installation comprising, in combination, a bed defined by a border of a plurality of adjoining hollow edging elements, each edging element being a unit of inverted U-shaped cross-section the open side of which, in its assembled position, faces downwardly, the limb which faces the contents of the bed being provided with a foot section which extends under the contents of the bed and the facing internal surfaces of the limbs being provided with at least one pair of mutually opposite guide elements for the reception of transverse partitions, an underlying support supporting the edging elements, a separating layer disposed on said underlying support, said separating layer being a sheet which separates the contents of the bed from the underlying support, a drainage layer of water-storing material provided on the separating layer for regulating watering of the bed, a filter element disposed as a layer on the drainage layer, and a substrate located above the filter layer for receiving plants and/or seeds.
