Add height and color to your garden with a classic wood arch, built from a kit and framed with climbing roses and clematis.
When to Start: Spring to fall
At Its Best: Spring to summer
Time to Complete: 1 day
Lay out all the pieces in the kit on the ground. Starting with the roof of the arch, align the short horizontal pieces so that they slot into the two long crossbeams that make up the roof. Use a tape measure to check that they are evenly spaced.
Using galvanized screws and an electric screwdriver, join the horizontal pieces to the beams. Then, attach the two vertical sides of the arch onto the roof, as directed by the kit instructions. The trellis sides in this arch came in two complete sections that are slotted into the roof.
To secure the arch in the ground, stand it in its final site, and mark out the positions of the four vertical legs. Dig holes for the legs, 18 inches deep and 12 inches wide. Add a 2-inch layer of rocks or broken bricks to the base of each hole.
Tamp down the rocks with a pole. With help, lift the arch and lower its legs into the holes. Make sure each leg is standing on the base, and add or remove material until all four are solidly supported.
Make sure that all the verticals are correctly aligned, and that the horizontal pieces are level. If necessary, maneuver the arch until it's perfectly upright; when you're satisfied that it is, pack more rocks around the legs.
Pour the ready-mix concrete into each hole, up to ground level, ensuring that it completely surrounds the legs. Slowly add water to the holes to soak the concrete, and allow it to dry and harden for a day or two. Now stain the arch in your chosen color and plant around it.
