Roses climbing up a trellis can add vertical interest and a focal point to your landscape. The paint color of the rose trellis can complement the structure holding the trellis, match the color of nearby fencing or provide a contrasting color background for the roses that meander up the trellis. Painting a rose trellis can help protect the wood from decay caused by sun and rain. The best time to paint a rose trellis is before it is assembled. If you already have a rose trellis assembled and in use, periodic painting can extend its life.
Spread at least two layers of newspaper or a paint tarp on the floor to make cleanup easier. Sand any part of the trellis that is not pre-sanded. Wipe off the sanded pieces to remove all residuals.
Apply primer/sealer for wood and allow it to dry according to the manufacturer's instructions.
Apply one to two coats of exterior paint and allow it to dry according to the manufacturer's instructions.
Assemble the trellis and touch-up areas, if necessary, before securing the trellis to the desired structure.
Prune the roses. A climbing rose can be cut back in the fall when the plant is dormant. Remove the plant from the trellis and lay it on the ground. Prepare the plant for winter if your rose variety is not cold hardy in your zone. Otherwise, the rose can be reattached after painting the trellis.
Remove the rose trellis from the support structure or ground for a smaller, freestanding trellis.
Spread at least two layers of newspaper or a paint tarp on the floor to make cleanup easier. Use a scraper to remove loose pieces of old paint from the trellis. If the trellis is held together with screws, disassemble it for easier scraping and painting.
Sand the trellis and wipe off any dust. Follow Steps 2 and 3 under New Trellis for painting instructions.
Reinstall the trellis, touching up any nicked spots and then reattach the cold hardy rose.
