How to Make a Wood Trellis Circle

Updated February 21, 2017

Trellises come in a variety shapes, sizes, designs and materials. Wooden trellises add a natural decorative element to a yard or garden and provide a vertical space for plants to grow. Some plants need to grow vertically, while others can be trained to grow along a trellis to free up valuable ground space. A wood trellis circle is one popular shape that can add visual interest to your garden.

Put on your safety glasses. Determine the size of the circle that you want to make. Use a tape measure to measure the length of the radius of the circle on the 1-inch-by-1-inch board. Use a pencil and mark that length on the board. Add one inch to that length and make a mark at that measurement.

Use a mitre saw to cut the 1-inch-by-1-inch wood board at the second mark. Measure half an inch from one end of the board and make a mark. Lay out a wooden lattice panel on the work surface. Place the wood board in the centre. Hammer a finish nail into the mark that is half an inch from the end, so that it holds the board but allows it to turn freely.

Hold the pencil at the unattached end of the 1-inch-by-1-inch wood board. While still holding the pencil to the unattached end, begin to pivot it in a circular motion. The pencil will mark along the wooden lattice panel. Continue to move it in a circular motion until the pencil line meets the beginning point.

Cut out the wooden lattice panel using a jigsaw. Lightly sand the edges of the circle with a piece of 120-grit sandpaper.

Select a spot for your trellis, keeping in mind the sunlight requirements for the plants you desire to plant. The circle trellis will be mounted to the two 8-feet-long, 4-inch-by-4-inch posts. Measure the diameter of the circle. Make a mark in the ground to indicate where the two posts should go.

Dig a hole at each mark using a post hole digger. The depth of the hole should be at least three feet. Place each post in the hole. Fill the dirt back in slowly while holding the post upright. Ensure that the posts are level by placing a post level on them. Pack the dirt in around the post to ensure that it is firmly set in the ground.

Place the trellis circle at the desired height along the two posts. Use a hammer to drive finish nails into the post to attach the trellis circle. Space the nails approximately six inches apart.

Prepare the area in front of your trellis by digging down six inches into the dirt. Be sure to turn the dirt over and break it up so that it is very loose. Follow planting instructions specific to the kind of plant you desire to have growing along your wood trellis circle.


Combine several circles to your trellis for a custom decorative design.


Always read and follow operating manuals for tools prior to use. Wear safety glasses when working with wood.
