Rose plants require a lot of aftercare, including proper watering, soil conditioning, fertilizer, and most importantly, pruning. Cutting a rose bush prevents the development of disease by promoting air circulation and removing broken, dead or diseased portions of the plant. Pruning also controls the size of the plant and how the flowers bloom, and protects your plant for the winter to ensure the best growth in the spring.
Cut flowers from the rose bush for flower arrangements in the homes by cutting at a 45 degree angle just above a node, where leaves are sprouting from the plant stem. Remove the flower at a node that leaves two, five-leaflet leaves remaining on the rose plant, says the University of Missouri Extension service.
Remove any canes from the plant that are damaged by insects or weather, or are diseased, to prevent the spread of further illness, suggests Texas A&M University.
Cut away the weaker can of any two canes rubbing against each other, says Texas A&M.
Remove any canes that are smaller than a pencil in diameter or look weak, says the University of Illinois.
Remove suckers that appear at any grafting point on the plant, digging down to the roots of the rose plant, where the sucker is growing, and tearing it off by hand. The University of Illinois recommends tearing it to prevent new growth.
