How to Build a Container Trellis
Transform a potted vine from a spillover creeper into a reach-the-sky climber when you give your plant a vertical structure to latch onto.
Trellises make growing vines a cinch, and keeping plants off the ground (and in the air) makes them less susceptible to unwanted pests. Plus, there are countless places you can put your potted trellis: In the garden, on a patio, and dressing up an entrance are just a few options. We planted our container with tomatoes and basil, but use whatever climbing plant fits your needs.
Before You Start: Prepare the cedar strips in advance by soaking them in water for at least 12 hours to make them easy to bend. The cedar can be cut from screen molding. If you can't find cedar, you can use pine, oak, or poplar—just make sure to water-seal them.
The finial can be found at hardware and crafts stores. Some come with a screw on the end already, but if you're using one without a screw, you will need a hanger bolt (double-ended lag screw) that's 3/16x1-1/2 inches. This can also be purchased at a hardware store.
