How to build a tree pergola

Updated February 21, 2017

Tree pergolas give your garden a rustic, old-world theme. Not only are they cheaper to construct than store-bought self-assembly kits, they are easier to tailor in terms of size. A pergola will provide shade and shelter for potted plants and structure for climbing plants.

Select which trees to use for the pergola. A conventional pergola shape is square, but any shape can be made, provided the trees are close enough together.

Measure the wooden canes against the distance between the selected trees. Store-bought pergola posts are 6 feet apart, so roughly estimate the distance between the selected trees. The cane is long enough if the ends fit between the branches or overlap the tree trunk.

Bind the wooden cane at each end around the tree's trunk. It does not matter whether you knot or bind with the garden twine. Safety is important, so make sure the cane is bound securely. If you require a square shape, bind another cane between two opposite trees.

Make sure the garden twine will comfortably hold the weight of the canes. The tree's foliage will provide a natural roof for the pergola, but more wooden canes bound across the top in the opposite direction will help with strength and enclosure.

Tip

Do not use trees that are too tall or too far apart. Make sure the trees can hold the weight of the wooden canes before attaching. Use willow on the roof of the pergola. It provides a sturdy structure for climbing plants.

Warning

Do not use dead or rotten trees. The extra weight may cause them to break or fall.
