It’s the eternal struggle – the choice between a nice cedar arbor or a more functional and long-lasting structure. When first built, arbors like the ones pictured below are beautiful. The problem is that they instantly go into a state of decay because of the way they are built and the exposure the wood has to the elements. If vines or other vegetation are allowed to grow on an arbor, it decays even faster. The numerous joints on horizontal surfaces of the arbor will hold water, which will soak into the wood regardless of how well it is stained or painted. Within a few years all the little rotten spots will get out of hand and the structure will have to be taken down.
