Pergola posts should be securely anchored to concrete, though whether they should be embedded directly inside wet concrete or surface-mounted using heavy-duty metal brackets depends on your installation style. Sinking wooden posts directly into wet concrete holes is extremely sturdy, but it risks trapping moisture around the base, which can cause wood rot over time even with pressure-treated lumber. To prevent this, most modern builders prefer pouring concrete footings and attaching galvanized metal post brackets on top, keeping the wood elevated above ground level while providing exceptional wind and load resistance when fastened with heavy wedge bolts.
