Decorative trellis from hpotter.com
A trellis is a work of art to be decorated with flowers and foliage.
We typically see the fan-shaped trellis or rectangular one with a grid of cross-pieces. There are also decorative metal ones for sale in your local garden center.
However you can make a trellis out of anything that won’t harm the plants and make it any shape you would like.
Why do they need to be flat? Use your garden arbor or pergola as a trellis. Build one in the shape of an obelisk. With weather-proof twine you can have a series of straight lines in any direction with any spacing.
Shape it like your child’s favorite animal.
Search online to find photos of trellises made from horseshoes or containing glass disks. Make it from metal, wood or any material. Find a use for your old scraps of things. They can be shaped like a leaf or a tree. Use your imagination! The sky is the limit!
