1. Introduction

Living walls are a horticultural challenge which requires good planning, execution and maintenance in order to thrive. It is vital to check the quality of the materials and the method of implementation throughout the process and to pay particularly close attention in the first few months after the wall has been planted. Only a regularly maintained living wall will leave the client and other observers feeling content over the long term. In order to care for and maintain living walls properly, it is vital to possess basic knowledge of plants and their physiological needs, and to know how to identify and treat pests and diseases.
