The depth of your post hole depends on your post length. If you decide on a two-rail fence, the posts are likely 6 feet long. You want your hole to be at least 1/3 of the post length. In this case, your post hole should be two feet deep.

If you opt for a three-rail fence, the posts will typically be 7 feet long, meaning your post hole should be 28 inches deep.

Maintain your wattle fence by inspecting it at least twice per year for loose weaving and degrading branches. Replace any seriously degraded sections, ensure water drains properly around the posts, and trim any sprouting branches if you used green wood. If you notice the weave loosening, you can often tighten it by gently pushing down on the top branches. You can also apply a natural wood preservative every two to three years to extend the fence's lifespan.

Whether you need a permit to build or install a fence depends on several factors, including your location, the fence's height, its placement in your yard, and the materials used. In many cities and highly populated areas, a permit is required, especially for fences taller than 6 feet. Conversely, rural areas may have fewer restrictions. Typically, backyard privacy fences 6 feet or shorter do not require a permit, while front yard fences often have a lower height limit, sometimes as low as 3.5 feet. There can also be exceptions for properties in mixed residential-commercial zones. It's best to check with your local building inspection or zoning department to understand the specific requirements, height restrictions, and location rules for your area. A professional fence installer can help you navigate this process and often secure the necessary permits for you, though this may extend the project timeline.

Post depth for shadowbox fences should be at least two feet deep plus an additional foot for every foot of fence height above four feet. For a standard six-foot fence, this means a minimum depth of 3 feet. This depth helps to protect the structural integrity of your fence in the face of wind, soil movement, and seasonal ground shifts
