Webinar Description:
Why can't we save all the rain California got for the trees? Why do most trees not have deep roots? Why are compacted soils bad for your landscape? At the same time, why trees love grows roots under sidewalks in between concrete and compacted soils? 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 overwatered, you have two options: drain the water to save the plants (wastewater) OR save the water (waste the plants). What makes Plant Available Water different from the water applied to the soils? Why volcano mulching is bad for your trees while foot-deep leaf litter in natural forests is good for the trees? What is the difference between double/triple shredded mulch versus arborist chips? Stockpiling topsoil is common in the construction industry, and it is sold to the landscaping industry. What is the difference between stockpiled topsoil versus actual topsoil? After stockpiling for months or years, is it still soil or just dirt?

What is the one thing in common for all these questions? Soil Oxygen. It is the real limiting factor! Sign up for this Landscape Expo Webinar to learn more.

 

Learning Objectives:
1. Learn some of the common problems, misunderstandings we encounter in landscape and the common ways to get around these problems.
2. Demonstrate why soil oxygen is the real limiting factor and how fast it starts to affect the plant lives when overwatered, as well as methods of how to make use of the water that is otherwise wasted.
3. Learn some new methods and technologies that can not only address and alleviate the problems, but also make landscape designs better suited for the beautification and the long-term benefits of green infrastructure.
