Although bush-variety roses typically grow well without any support, climbing rose varieties grow upward in tall, thin canes that require something to cling to. Without the proper support, these canes will bend over into walkways or break off and damage the plant. While there are a wide variety of trellis materials to choose from, a basic wire trellis can be installed behind the roses and blends right in with the surrounding landscape.
Walk behind the roses on the left side and brush aside any mulch in an area approximately 6 to 8 inches behind the plant. Use a post digger tool to dig a 12-inch-deep hole in the location. Walk to the right side of the roses and dig a corresponding hole on that side as well.
Insert a 5- to 6-foot-tall wooden pole into each hole and pack the soil down into the holes tightly to hold the poles securely in place. Once installed, you should not be able to rock the poles.
Place the threaded end of an eye screw into the side of one of the poles facing toward the opposite pole. Install additional eye screws all the way up the wooden pole spaced at 8- to 12-inch intervals.
Repeat the process to install corresponding eye screws on the other wooden post, so that all the loops on the screws face inward toward each other.
Tie the end of a piece of fine-gauge, stainless-steel wire to one of the loops and stretch it across the back of the roses to the corresponding loop on the opposite pole. Cut the excess wire from the roll, using scissors. Twist the wire around the loop and use a pair of pliers to twist the free end around either the loop or the wire to secure it in place.
Repeat the process to install wire between the two poles at the locations of each remaining set of loops.
Secure the roses to the wire by either weaving them in between the wires or using 6- to 12-inch pieces of gardening tape looped around the roses and knotted behind the wire.
