Speaker: Wei Zhang, Ph.D., Vice President of Research and Development, Zynnovation LLC

This presentation answers common questions, such as: Why do we have to water trees so often? Why can’t we supply them with one year’s water supply at a time? Why don’t roots grow deep? Why is compacted soil bad for urban trees? Why is volcano mulching bad for trees while leaf piling against tree trunks in natural forests is good? Why is deicing salt bad for plants? What makes the space under sidewalks so attractive to tree roots? One thing in common with all these problems – Soil Oxygen! Join us for live demonstrations throughout the seminar.
