Making trees and wall plants thrive at steep quay walls
The wall design as the foundation of the nature-inclusive quays has already been described in The brickwork story behind GreenQuays; the focus of this article is on the vegetation - trees growing out of containers in the wall and herbaceous plants that nestle in the walls. It mimics the natural situation, where plants grow in rock crevices. This concept is different from conventional green walls where plants grow on the ground and climb the wall or grow in containers detached to the wall.
The first plants have been set and seeds affixed on experimental wall segments of the small-scale test site in spring 2020. The goal is to test the germination and survival of seeds and plants under different brick/mortar and substrate combinations and to figure out, how the process of vegetating, which normally takes several decades, can be speed up. The monitor results inform the design of the Real-Life Pilot site to be built from early 2022 on. How do they thrive?
