Typically, climbing roses can get a start on training in their second year. Roses use their first year in a new location to put down roots and become established. Let your plant grow horizontally, without too much pruning or trimming, and allow it to build up some length and bulk in the stems. After your climbing rose has been in place for two to three years, it's time to start training. To begin training climbing roses, place a structure or tying wire about two feet from the base of the plant. Here, you can begin tying in the rose and training it to grow upward. At the end up the first training season, your rose can be pruned. Remove old and damaged canes, and trim back suckers to direct energy to main stems. As you continue tying in your roses, moving upward on their support, be sure to provide plenty of room for the plants to grow both up and out. This creates a more pleasing shape and reduces overcrowding.
