Turn Basic Wood Trellises into a Stylish Outdoor Plant Stand

Cut 3/4-inch square dowels into 16 pieces, each measuring 11-1/4 inches. We used a miter saw for precise cuts. 

Use a tack cloth or brush to stain all wood surfaces, including the trellises and dowels, with black exterior stain. Wipe away any excess stain with a lint-free rag. To extend the life of your plant stand, choose an exterior wood stain plus sealant in an opaque finish, such as Olympic Maximum. Set aside and let dry completely.

Prime and spray-paint 8-inch-diameter duct caps to use as perches for potted plants. Remember to always work in a well-ventilated space when using spray-paint. 

Use an awl to punch two holes in the opposite sides of each cap, about 3/8 inches down from the top edge. If desired, drill an additional hole in the middle of each duct cap to allow for drainage.

Lay one trellis flat on the ground. Stagger caps, centering them within the square openings. Secure them to the horizontal trellis rungs using 1/2-inch screws. Flip the trellis assembly over and place it on top of the other one so it lines up. Secure duct caps to the second trellis using 1/2-inch screws. Stand up the assembly.

Using a pin nailer, attach dowels at each intersection. Repeat on the opposite side. Set planter pots into each of the duct caps. To prevent the tall plant stand from tipping over (and to protect it from the elements), secure it to a wall with screws or straps as a safety precaution.
