How to Plant Trees Near Septic Lines
Planting trees near septic lines requires careful planning. Trees improperly planted too close to septic lines can cause costly damage to the lines. Keep in mind that damage to the lines may not occur until after several years, when the tree reaches maturity. Also, the septic damage may not be evident until a serious problem occurs, resulting in replacement of the entire system. Septic line location, local zoning, tree selection and placement are all things to consider prior to planting. Does this Spark an idea?

Determine the depth and perimeter of your septic lines. If you are unsure of the location, you may need to hire a septic installer to help you. Contact your local Health Department to determine if there are regulatory setbacks to consider when disturbing the earth adjacent to your septic lines.

Consider which trees you wish to plant and what purpose they are serving. The type of tree you choose is very important. Avoid trees with root systems that may interfere with the septic lines. Trees fall into two categories of root systems: taproots and fibrous roots. Taproots are more likely to penetrate farther into the earth, while fibrous roots are more shallow. Roots will also spread out under the drip line of the tree, so be aware of the width of your tree when it is fully grown. Tree varieties that grow along riverbanks and in floodplains, such as cottonwoods and birches, are more likely to "seek out" water sources more aggressively than trees normally found in drier, upland areas.

Select the location and prepare the area for planting. Measure the tree root ball depth and width. Holes should be dug 6 inches deeper and 12 inches wider than the root ball. These measurements should be taken into consideration prior to digging the hole.
