Garden arches are one way in which gardeners can add vertical support to their gardens while at the same time defining spaces such as pathways and outdoor rooms. There are a number of plans online for building garden arches from wood, but if you are not mechanically inclined, you can still build a sturdy garden arch. All you need are a few tools from the fencing supply section of your hardware store.
Measure and mark the location of your T-posts in the ground with a measuring tape and spray paint. The posts should be 3 feet apart in rows that are 8 feet apart.
Drive the T-posts into the ground using fence post drivers.
Bend the welded wire into an arch that is 8 feet wide by 8 feet high. Place the arch against the inside of each T-post.
Attach each end of the arch to the T-posts on each side with fencing fasteners and pliers.
Plant climbing vines in the ground at the base of each side of the arch. Good vines to plant are lightweight climbing vines such as clematis or sweet pea.
