Should you use sonatubes for fence posts?

Using sonotubes for fence posts can be beneficial, especially in areas with unstable soil or where frost heave is a concern. They provide a sturdy, concrete foundation that helps prevent the posts from shifting. However, it's important to ensure the sonotubes are properly sized and installed to support the weight and height of the fence. Ultimately, the decision should consider local soil conditions and the type of fence being installed.
