Green Roof: Maintenance

Green Roof: Maintenance

A green roof requires regular irrigation until the plants have become established. Thereafter the plants need to be irrigated as and when necessary. This maintenance is determined by the type of vegetation, the depth and drainage characteristics of the soil and the prevailing atmospheric conditions. Opportunities exist for irrigation using water collected in the gutters of the roof and adjacent roofs and grey water from kitchens and bathrooms.

Green Roof: Plant Selection

Green Roof: Plant Selection

The ideal characteristics of the plants to be selected are that they are drought resistant and wind resistant, they small low growing, easily reproduce themselves from seed in the event that the plants die of during times of extreme heat or drought. In addition it is of advantage if they have a creeping habit so that they are easily able to fill gaps left by die back during times of moisture stress.
