Howdy from Coach Dave,

Your knockout roses most likely need some fertilizer, pruning, and mulch for the season change.

All plants have a bloom cycle and need to be trimmed if you want blooms to continue.

As a last tip remember, over fertilizing will slow down blooms, so use as directed.

Happy Gardening,

Coach Dave
