Sustainability Starts at the Tree Farm Steve Brown, A&S Horticultural | Brian Dierks, City of Maitland, FL About: Urban tree planting sites are very demanding on tree root systems. A tree's wind resistance, its ability to live in small soil volumes and establish after planting, are all connected to a tree having efficient, quality root systems. While a lot of education has been done to improve site conditions to provide good rooting environments, what about the quality of roots you purchase? Current research on nursery production methods has improved root quality and distribution.
