While reading the Western Arborist, an tree industry publication, I came across a top ten list of what we have learned about trees by Nelda Matheny and Jim Clark, both very well known researchers, teachers, lecturers and industry titans. I have had the honor to meet both, read their work and attend their workshops. So when I came across their top ten list, I felt compelled to share it with you. 10. Our view of trees has evolved from being niceties to being necessities. 9. Tree preservation requires space. 8. Tree care practices can have either positive or negative consequences. … Read More
One common garden myth is trees have long tap roots extending straight down into the ground. This is a common misconception of root growth, an incorrect perception shaped by “common sense” assumptions, not scientific evidence. Most of us have seen seedlings germinate and immediately grown a “tap root” into the soil. The root growth occurs prior to the seedling growing new leaves. Once the tap root is established, new leaves begin to appear. People generally think the tap root continues to grow downward, in essence resembling an enlarged carrot or a Christmas tree form. The misconception of the tree crown … Read More

Who is Better Qualified to Opine on Root Damage, Civil Engineer or Certified Arborist? I was retained by a defendant attorney to determine whether her client’s tree was responsible for lifting the adjacent civil sidewalk that resulted in a plaintiff trip and fall lawsuit. Based on the photographs and tree species, White mulberry (Morus alba), I was fairly certain her client’s tree was responsible for the sidewalk damage. The attorney retained me and requested a site inspection and tree root assessment. I trenched adjacent to the sidewalk and within a short time, encountered a three-inch diameter root growing under the … Read More
Rarely have I seen a successful turf block driveway. Turf block, turf stone, turf pavers are systems installed as living turf driveway alternatives. The material provides structural support via plastic or concrete cells that are filled with a soil media for turf installation. The block is designed to support vehicular traffic on driveways while providing a green alternative to concrete or asphalt driveways. Turf blocks have been used for decades, but rarely have I seen thriving turf grass within the block. Not because of the product, but usually due to turf establishment and failure issues. Due to reduced soil root … Read More
