Extensive vegetation used in GREEN FLOR consists of plants with minimal vegetation requirements. These are self-sustaining and self-growing hygrophobes. These are low maintenance plants. They spread both through vegetative propagation and generative reproduction. GF vegetation mats include different types of plants: herbs, stonecrops, perennials, different types of grass and moss.
Extensive GF system is a low maintenance, self-sustaining system. This system is self-reliant because the natural processes that take place in the substrate layer provide the plants with all the nutrients they need for growing. Water shortage is compensated with carefully chosen mechanisms. Whole vegetation is a closed-loop system, where old plants die, sowing and growth of new plants take place naturally. This closed-loop system can be supported by minimal amount of maintenance.
Maintenance that should be carried out once or twice a year (depending o needs) is limited to the following activities:
- providing necessary nutrients to plants through fertilization,
- irrigation of those areas of the roof which are exposed to extreme heat from sunlight,
- removal of unnecessary plants,
- filling empty spaces with stonecrop saplings previously taken from densely covered areas,
- filling in substrate around eroded areas,
- removal of plants from technical equipment.
