Garden arbors create a charming transition from yard to garden, sidewalk to home or as an accent over your garden path. An arbor can create a grand entrance into your garden as well.
You'll definitely want to consider the type of plants you'll be growing on it if any. If you're going to grow heavy plants on it, you'll need a sturdy arbor to support those plants. With a large selection of both wooden and vinyl arbors available you should have no trouble finding a beautiful addition to your garden.
