How Far to Plant a Tree from Underground Utilities

Planting a tree in your yard can bring beauty, shade, and even fruit to your property. But before you start digging, it's important to consider the potential risks posed by underground utilities. Planting a tree too close to these utilities can cause serious problems, including power outages, gas leaks, and costly repairs. Here's what you need to know about how far to plant a tree from underground utilities.

Identifying Underground Utilities

The first step in planting a tree safely is to identify any underground utilities on your property. These may include gas lines, electrical lines, water mains, and telecommunications cables. Contact your local utility companies to have them mark the locations of these lines before you start digging. This is especially important if you plan to dig deeper than 12 inches, as this is typically the depth at which most utilities are buried.

Danger Zones

Once you know the location of your underground utilities, you can determine a safe distance for planting your tree. The danger zone around many utilities is typically 10 feet on either side of the line, although this can vary depending on the type of utility and your location. Planting a tree within this zone can damage the utility, cause outages or leaks, and put your safety at risk.

Recommended Distance

To avoid these risks, it's generally recommended that you plant trees at least 20 feet away from underground utilities. This distance may need to be greater depending on the size and type of tree you're planting. For example, smaller trees like dogwoods may be fine at a distance of 20 feet, while larger trees like oaks and maples may need to be planted 50 feet away or more. Your local nursery or arborist can help you choose the right tree for your location.

Alternative Planting Methods

Alternatively, you may be able to use a tree-friendly planting method that avoids the danger zone altogether. One such method is to plant a raised garden bed above the utilities. This can provide a safe and attractive home for a tree, while also allowing you to control the soil conditions and water flow. You can also consider container planting, which allows you to move the tree if necessary and control its size.

The Bottom Line

Planting a tree is a great way to enhance your property, but it's important to keep underground utilities in mind. By identifying the location of these utilities, determining a safe distance for planting, and using alternative planting methods when necessary, you can enjoy the beauty and benefits of trees without risking your safety or utility service.
