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.

You have several options for anchoring a temporary fence to keep it from falling down. Sandbags can be used as a standard weight, but they may blow away or fail in strong winds and inclement weather. Spikes and bolts are a cost-effective and easy-to-install alternative, but drilling can be difficult if the ground is frozen, too soft, or too hard. Another option is wind braces, which should be bolted into the ground to withstand turbulent wind; however, like spikes, they can be challenging to install in very soft or hard ground.

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.

The average lifespan of a wood fence is 15 to 20 years, but some can last for 40 years or more depending on several factors. The type of wood is crucial; for example, untreated pine may only last 5 to 10 years, while pressure-treated pine can last up to 20 years, and cedar's natural resistance can extend its life to 40 years. Other factors include local weather conditions, with wet and windy climates causing faster deterioration, and the quality of maintenance. Higher-end wood, metal posts, and privacy fence styles also tend to last longer.
