How close can trees and shrubs be to the drainfield?
Trees and large shrubs should be kept at least 30 feet away from your drainfield. Be aware, though, that certain soils may require plantings be a greater distance away. If you wish to plant trees near a drainfield, consult an expert who can determine types of plants and distances, based on your soil. Trees and shrubs generally have extensive root systems that seek out and grow into wet areas, such as drainfields.
