Red cedar is the most widely used wood while building this structure in the garden. It is used because cedar is strong and light weight, it has good resistance to most weather conditions. It can also be shaped into different designs without much difficulty.
✦ You can build an arbor as a doorway to your garden and have some ivy on it for 'secret passage' look. Have a structure sporting crisscross wood work, plant a few roses or other plants next to it, to add some color to it. Some people even have a bird house on the side of their arbor, giving it a unique appearance.
✦ Another idea is to build a tunnel shaped arbor as a passageway leading into the garden or connecting two areas of your yard.
This is easy to build, all you need to do is dig holes on either side of your pathway, stick poles in the holes, and connect these poles at the top. Plant a couple of vines and guide them to form a canopy of leaves and stems on the roof of your structure.
