In addition to keeping abreast of international developments in the urban tree planting sector, Greenleaf have our own research plantings at various UK locations and we are actively supporting two leading Arboricultural Universities in their trials.

Over the years, an impressive collection of data has been accumulated and continues to grow. The research conducted by Greenleaf is not without its own challenges. Live street tree excavation is rarely an option, but we have been fortunate enough to encounter several opportunities where the authorities concerned have allowed us to gather data from mature street trees.
