Soil Cells vs Structural Soil: Analyzing Soil Under Pavement

What is the best way to promote tree root growth in the soil under a sidewalk? It’s a question that landscape architects, civil engineers, and arborists from cities large and small have investigated over many years. Through such consideration, alternate solutions to increase rooting volume for street trees have been created with varying degrees of success. In […]
