We learned about the Texas Trees Foundation’s Cool Schools Program back in early 2018. This organization is dedicated to enhancing outdoor learning spaces for schools. We were eager to donate TreeDiaper^® technology to the cause!

Dr. Yang visited Dan Rogers Elementary School to take some photos in April 2019. Three years later, we were glad to receive some more photos from a friend. These images are summarized below.

The six trees shown were planted at the same time. Three trees were planted with TreeDiaper^® and three were planted with a competitor’s product. Trees #1 and #2 were installed with the competitor, trees #3 and #4 were installed with TreeDiaper^®, and trees #5 and #6 received both products.

In the Sept 2024 pictures, TreeDiaper® only group (#3 and #4) outgrow the other trees significantly. Tree #5 died for unknown reasons.

We observed that the trees with only TreeDiaper^® were in the best shape after three years. The trees with only TreeDiaper^® were found to be the most successful, while those with a combination of TreeDiaper^® and the competitor were less successful because the rainwater harvesting feature was compromised.
