Pruning roses should take place in winter or early spring. Cut back your rose plants to about 1 foot tall.

You can prune this rose shrub into a yellow knockout rose tree if that is your desired shape.
Fertilize your rose bush near the root ball once a year in early spring with slow release fertilizer to give it a nice boost for growth and flower production. Water thoroughly the first year of planting to establish a strong root system.
