The answer to 'why is my fence erosion' is that fence erosion is a common issue caused by factors like soil washout, heavy rainfall, or poor drainage. Symptoms include leaning or uneven fence posts, gaps between boards, and soil buildup at the base of the fence. Solutions can include adding soil or gravel, reinforcing posts, and improving drainage around the fence line.
Fence erosion is often a gradual process, so it's important to address it early before it becomes a more serious problem. Depending on the extent of the damage, some fence erosion issues can be DIY projects, but for more complex or structural problems, it's best to call in a professional landscaper or fencing contractor.
