Climbing rose bushes add a beautiful touch to any landscape or garden, especially once they are full grown on a wall or trellis and in bloom. In order to promote new rose blooms, as well as maintain the shape of the rose bushes, they must be pruned each winter while dormant to get rid of dead canes. It's important to know the right way to prune the climbing roses so you don't harm them. The key is understanding that a climbing rose bush should accent a wall or trellis, not overpower it and grow completely wild.
Put on the gloves to protect your hands from any thorns or brambles. Make sure your pruning equipment is sharp and clean.
Locate the dead, broken, or diseased canes (otherwise known as trunks), and trim them to the base of the climbing rose bush first. Then prune back any canes that are crossing each other, tangled badly, or growing out at awkward angles where it doesn't have support.
Find the four to six strongest trunks (these are the main parts of the rose bush). Prune back all the canes growing from these trunks, whether they are healthy or not. This encourages new growth for the next season.
Use plant ties to secure the main trunks to the trellis or wall so that the bush has a re-secured support system.
