How to Install a Sturdy Garden Fence

Fences define the edges of your sanctuary, providing both a physical barrier and a clear sense of order to your landscape. Whether you are keeping curious rabbits out of your vegetables or simply creating a clean aesthetic line, a fence is only as good as its foundation. A job well done means posts that stay vertical through the seasons and pickets that remain flush against the rails. Investing the effort to dig deep and get your post spacing perfect now will save you from a leaning or sagging structure in a year's time. Work slowly, check your level constantly, and remember that your fence will settle, so plan for ground shifts as you set your depths. When done correctly, your fence becomes a permanent, reliable piece of your outdoor infrastructure.

  1. Square Your Fence Line First. Drive wooden stakes at each corner of your fence line and pull a taut string line between them. Measure along the string to mark exactly where each post will go, ensuring consistent spacing.
  2. Go Deep for Stability. Use a post hole digger to excavate holes at each marked location to a depth of at least 24 inches. Ensure the holes are roughly three times the diameter of the post for proper concrete support.
  3. Lock Corners Plumb and True. Place your corner posts in the holes and pour gravel into the base for drainage. Add concrete mix and water, checking frequently with a level on two adjacent sides to ensure they are plumb.
  4. Align Posts to the Line. Once the corner posts have cured, attach a string between them at the top to act as a guide for your remaining line posts. Repeat the setting process, ensuring each post touches the string but does not move it.
  5. Brace With Staggered Rails. Measure and cut your 2x4 rails to span the distance between your posts. Fasten them securely using exterior-grade screws, ensuring they are level and spaced evenly from the top and bottom of the posts.
  6. Space Every Board Identically. Nail your pickets onto the rails, keeping a consistent gap between each one if you are using a spaced design. Use a spacer block of wood to ensure every board is placed exactly the same distance apart.
