How to Make a Trellis for a Mailbox Garden

By Callie Barber ; Updated September 21, 2017

As one of the first things you see when entering your home, a mailbox is a simple way to make a lasting impression. Plant vibrant flowers around the base of the mailbox for a quick, easy update to your space. Add an elegant trellis nestled next to your mailbox with a dripping jasmine vine creeping up the structure to welcome all who drive by. Plant something unexpected, like the sweet pea, to create a lush and exotic feel.

Clear out the space around the mailbox of weeds and debris. Remove all rocks and sod around the mailbox to ensure a level surface for the trellis.

Add a layer of nutrient-rich potting soil to the ground around the mailbox to prep the soil for the trellis structure. Rake the soil to create a smooth surface and to remove any remaining clumps and debris.

Insert three 1-inch by 5-foot-long dowel rods into the soil on the side of the mailbox. Make sure they are at least 5 inches from the mailbox and 2 inches apart. Allow at least 1-2 feet for the “feet” of the trellis to be planted inside the soil.

With the dowel rods in the soil, take a piece of garden wire and begin wrapping the tops of the dowel rods together. Place the garden wire around the first rod, over to the middle dowel rod, and then lastly around the last rod.

Wrap the rods until your have at least three layers of garden wire. Pull tight so that the tops of the rods come together, forming a teepee-shaped top.

Press the soil around the “feet” again to secure the trellis into the ground for a snug fit. Plant your favorite flowering vine, like clematis or moonflowers, in the nutrient-laden soil for a colorful mailbox design.

Water your mailbox vines until fully established. Add a 2-inch layer of mulch around the newly planted vine to help retain moisture in the soil.
