Q.What’s Up With This Cane On My Knock Out Roses?

Zone 46322 | Tommystix added on June 16, 2021 | Answered

Hi! This bush gave me plenty of blooms in early June. Recently I noticed his cane in particular has light green leaves and has splits in the cane, and hasn’t produced a second round of blooms like the two I have planted next to it. Is this winter damage? The cane also gets to be almost black towards the base. Should I remove this stem? Thanks in advance!!
