It’s knockout rose trimming time! This happens twice a year, and August is one of them. During this trim, you want to remove about half of the plant. New blooms come from new growth, and new growth comes from trimming. This time of the year, the plants tend to get leggy and tall. Most of the new growth comes from the top of the plant. The bigger the plant gets, the more it tends to shade out the bottom, which prevents much of the new growth. By trimming the plant, it thins out the older, dead wood and makes way for new growth and blooms! If you have any questions, please let us know!
