To ensure abundant flowering, roses need to be pruned back in the spring. Only a rose bush that is cared for and trimmed is likely to produce beautiful flowers.
The most important rules for pruning roses are: Always start just above a bud and cut slightly at an angle. If frost penetrates the fresh interfaces, the branch could otherwise die. If the rose is already growing luxuriantly, prune it hesitantly. If your climbing rose blooms once, radically cut back the side shoots that have borne flowers.
