Putting up a garden fence comes down to planning the line, setting posts plumb in concrete, then attaching panels or wire.
Putting up a garden fence is a weekend project with a simple backbone: mark the line, check for buried utilities, set posts that sit below the frost line, and hang whatever panel or wire system you chose. The method shifts a little between wood panels, welded wire, and no-dig kits, but the order stays the same. Do it in the right sequence and the fence stands straight for years; skip the layout and drainage work and you’ll be redoing a corner by autumn.
Planning the Fence Line Before You Dig
Lay the fence line out with stakes and string before anything touches the ground—it’s the single cheapest way to avoid a crooked fence. Use the 3-4-5 triangle method to square corner posts, and double-check your property line if the fence sits near a neighbor’s boundary.
Call your local utility locating service to mark buried lines before you dig a single posthole. Postholes can shear through water, gas, or electric lines, making a simple Saturday project into an expensive repair call.
Setting Posts the Right Way
Dig each hole roughly one-third of the post’s length, which puts most backyard garden fence posts about 2 feet deep; in cold climates, go below the local frost line. Drop 3 to 4 inches of gravel in the base so water drains away from the wood and doesn’t pool against it, which is the main cause of rot at ground level.
Set the post on the gravel, plumb it with a level, and brace it before backfilling. For wood fences, pour concrete around the post and let it cure fully before hanging anything—posts that get loaded with panels before the mix sets will lean. Gravel backfill works for wire and no-dig setups that don’t need the same rigidity, and it lets moisture move freely out of the hole.
Post Spacing and Gate Openings
- Standard panel spacing runs from 6 to 8 feet depending on the fence system.
- Gate posts take the most load—size the opening for what will roll through it, about 36 inches is right for a wheelbarrow.
- No-dig fences drive spikes through post tops, so spacing follows the manufactured panel widths.
## Attaching Panels, Wire, and Gates
Wood panel fences get pressure-treated gravel boards laid at ground level first to keep the panels off damp soil, then the panels slot between posts with brackets and screws.
Welded wire runs faster. Set metal posts, unroll the wire along the line, and clip or staple it to the posts with tension kept even so it doesn’t sag between bays. Crimp the wire ends tightly against the end posts, and keep a fence stretcher handy for corners. No-dig panels are quicker still: drive the spike with a wood block over the top, slide the post through the stake eyelets, and connect the overlapping panels until the run completes.
Gates go in last; hang hardware after the posts have fully set so the alignment doesn’t drift as the concrete cures.
| Fence Type | Post Setup | Panel or Wire Attachment |
|---|---|---|
| Wood panel | Concrete-set posts with gravel base | Gravel boards plus U-brackets and screws |
| Welded wire | Metal posts, set or driven | Clipped or stapled with even tension |
| No-dig panels | Spikes driven with a block, no concrete | Posts slide through eyelets, panels connect |
## Common Mistakes That Ruin a Fence Build
Skipping the square check is the most common failure—panels misalign and the fence line drifts out of square within a few bays. They’re hard to fix once the concrete sets, so lay the string line carefully the first time.

FAQs
How deep should garden fence posts be set?
Plan for roughly one-third of the post’s length underground, which puts most backyard posts around 2 feet deep. In cold climates, go deeper than the local frost line so the ground can’t heave the post out of alignment.
Do I need gravel at the bottom of a fence post hole?
Yes, add 3 to 4 inches of gravel before the post goes in. The gravel drains water away from the base of the wood, which cuts rot risk significantly and slows frost-heave in cold regions.
Can I put up a garden fence without concrete?
Yes. Gravel backfill works for wire and no-dig systems where the posts aren’t load-bearing, and no-dig fence spikes get driven directly into the ground. Concrete is worth the extra effort for wood panel fences that carry weight and wind.
