What Can Be Planted Near The Septic System?

Posted on: 24 November 2019

If you live in an area where you must use a septic system instead of the municipal water system, then it is important that you take the necessary steps to protect the system from damage. One of these steps is taking care in the planting of trees, plants, shrubs, etc. over and near the tank and drainfield. Here is what to know about what is safe to plant in the septic system area of your property.

Shallow-Rooted Perennials and Annuals

If you like perennials and annuals, then you will want to stick to the ones with shallow roots and soft, green stems, such as groundcovers, weeds, and bulbs, as these are well-suited for the septic system area of your landscape. However, make sure that you focus on the plants that are ideal for your specific region's soil type, climate, average rainfall, and available sunlight. In doing so, you will minimize—or possibly even prevent—the need for watering and fertilizing down the road, further protecting the septic system.

Shallow-Rooted Trees

Though it is advised to never plant trees over your septic system, there are some trees that can be planted near the area. For instance, trees with non-invasive and shallow root systems, such as hemlock, crabapple, cherry, and dogwood trees are excellent choices to be planted near your septic system without causing any harm to it. However, it is important that you ensure you leave the distance that is equivalent to the tree's mature height. For example, if the tree will reach 30 feet at maturity, then it should be planted a minimum of 30 feet from the septic system. Trees that should be avoided around the system include those with fast-growing, woody roots like maple, willow, and pine, since they are attracted to the water that sits in the plumbing pipes.

Fibrous-Root Plants

Another option that you have are shrubs and trees that have fibrous-root systems, such as ornamental grasses, as these tend to grow closer to the surface of the soil. If these plants are planted over the septic system, they can help to minimize the erosion of the soil and siphon excess moisture, reducing flooding after heavy rainfalls. In addition, these plants encourage the exchange of oxygen in your drainfield, which is necessary for the filtering of any bacteria that remains in the wastewater.
