Why is it that most trees do not have deep roots?
Why is it that compacted soils are bad for your landscape?
At the same time, why do trees love to grow roots under sidewalks?
We all know overwatering creates an anaerobic condition that is bad for roots, but how long does it take for the process to start? When your plants are over watered, you have two options: drain the water to save the plants with water being wasted or save the water with the plants being wasted. Can you save both the water and the plants? Yes, sign up to learn more.
Why do we have to water our plants with frequent, but little water each time? Why can't we supply them 1 year of water a time? What makes Plant Available Water different from irrigation water? Why is volcano mulching bad for your trees while foot-deep leaf litter in natural forests is good for the trees? What is the one thing in common with all of these questions? Soil Oxygen is the real limiting factor! We will use live demonstrations (when possible) to show the difference soil oxygen has in some situations.
1. Learn the benefits and importance of urban forestry.
2. Study and learn common causes of plant death in urban environment.
3. Learn new technologies that help to solve the problems.
Wei Zhang holds a Ph.D. degree in Engineering from Virginia Tech. He has been doing research & development for the green industry for 10 years. His research areas include watering solutions for landscape plants, plant health, and plant protection against stresses like drought and road salt. His work also provides novel solutions to green stormwater infrastructures, for which plants are used for the treatment of pollutants in stormwater. He has more than 40 peer-reviewed scientific journal articles, one monograph, and more than 100 conference presentations. He has been a frequent speaker on Arboriculture, Landscape Architecture, Urban Forestry, Stormwater Green Infrastructure, and related conferences.
