What issue can trees planted in wells surrounded by pavement face?

Trees planted in wells surrounded by pavement can primarily face the issue of flooding due to the limited space for water absorption and drainage. When rainwater or irrigation is applied, the surrounding pavement can impede the natural absorption and circulation of water into the soil. This situation can lead to water pooling around the roots, preventing adequate oxygen flow and causing root-related problems, which may ultimately affect the tree's health.

While flooding is a significant concern, it is also essential to understand that the urban environment presents other risks, such as overheating. The pavement absorbs heat from sunlight, which can raise the surrounding temperature, stressing the tree. However, addressing flooding encompasses the mechanical barriers that pavement presents, making it a more immediate issue for tree health in that specific context.

This understanding is essential for landscape contractors to ensure proper placement and care of trees in urban environments, highlighting the need for adequate drainage systems.
