Site evaluation is the first step in selecting proper trees for a planting site. It is important to consider both above-ground and below-ground site attributes. This fact sheet discusses in detail above-ground attributes (such as light, slope, wind, salt, existing trees, overhead wires, street and security lights, buildings, signs, vandalism, and regulations) and below-ground attributes (such as soil pH, drainage, depth, salinity, distance to the water table, and obstacles to root growth). Irrigation, pruning, fertilization, pest control and desired tree attributes (such as function, size, form, and longevity) are also described in detail.
