Whether you’re installing a new fence or need to make repairs, digging out holes for the fence posts is an important step in the process. No matter what it will be used for, a sturdy barrier will require the right conditions and measurements. Fortunately, a little planning is all you need. Here are a few tips to keep in mind as you begin your project.

How to Dig Fence Post Holes

1. Know the Measurements

For 4 x 4 fence posts, you’re usually working with wood that’s 8 feet long, 3 feet of which should be in the ground. If you’re working with metal T-posts that are 7 feet long, you’ll only need to bury 2 feet.

2. Check the Soil

Trying to dig into rocky or sandy ground is problematic. Hard soil filled with rocks is tough to work with, while overly sandy soil will continuously refill no matter how much you dig. Both can be frustrating and will make getting the right size hole difficult.

3. Saturate the Area

Fencing experts recommend soaking the ground with water and then making a hole in the ground about a foot deep. Fill that hole with water and let it soak into the soil overnight. This is particularly helpful for sandy or clay soil that’s harder to work with. The water will make easier to manipulate.

4. Use a Hole Digger

Post-hole diggers will help loosen the ground. Choose a compact, light design, and be sure to move around the hole in a circular motion as you chop through. Hold onto the digger with both hands and spread the handles so that the blades and jaws are working through the area. Make sure to remove loose dirt as you work to your desired depth.

5. Try Excavating

Before using a digger, start a hole with a round-point shovel. Switch to a trench shovel as you go deeper. After about 2 feet down, move to the digger. Add a digging bar so that the chisel end can break the soil at the bottom while working the sides for a cleaner hole. Drop a small amount of gravel into the bottom of each hole to improve drainage.
