Garden walls are the most maintenance friendly system on the market today. Potted plants sit in rows and absorb water through capillary action when irrigated. If one plant needs to be replaced it can be easily exchanged for another potted plant without messy replanting, disassembling or cutting out parts of the living wall system. The benefit to this is lower maintenance costs for the end user, especially at heights where safety is crucial. We typically use this system for all of our interior projects whenever possible.
