It Is Not Your Fault That The Plants Died Shortly, But You Could Give Them A Better Chance Of Survival


1 ASLA PDH and 1 NALP CEU available through Zynnovation LLC. Contact instructor at for more information.

There are a lot of factors that can contribute to the survival and thrival of newly transplanted plants in the landscaping industry. The most common reason is soil moisture: either not enough (underwatering) or too much (overwatering). Landscape architects typically are not the party to blame if proper maintenance instructions have been included. Landscape contractors, who are typically only awarded a short maintenance contract, are not the responsible party either. The vast majority of failure cases are due to the lack of recognition that plants, especially larger woody plants (trees and shrubs), require a much longer time to get established.

As a landscape architect or landscape contractor, you can get away with a disclaimer. But it doesn’t mean your project will look good. Is there anything that landscape architects and landscape contractors can do to give plants a better chance to survive?

By examining the situation and looking at the root of the problem, the real limitation is in the Plant Available Water (PAW). No matter how much one irrigates the soil or how much rainwater falls onto it, any water above the Field Capacity (FC) is wasted. Conventionally, you can’t increase the FC freely, as it is defined by the texture of the soil. Among different soils, clay and sandy soils are the worst in terms of providing PAW for plants.

Join Forester University for this live, educational webinar as returning speaker Wei Zhang (Zynnovation LLC) reviews some technologies for stabilizing soil moisture, including methods that significantly boost PAW without drowning plant roots. We will also review methods and technologies that make the best usage of natural precipitation (stormwater). Case studies across North America will be used to illustrate how these methods can significantly reduce the need for maintenance and, therefore, the reliance on landscape contractors to keep plants alive.

Learning Objectives 

  • Understand the environmental and societal benefits of green infrastructure and urban forestry
  • Study the main technical challenges encountered in green infrastructure, urban forestry, and the landscaping industry
  • Learn that the most important factor for the survival of newly planted plants is soil moisture, not how much water is dumped onto the planting area
  • Learn how to solve problems with real-life case studies across the United States
