Deadheading roses is common practice and is easy. Their are a few reasons to prune back the dead flower heads on roses.
- By removing the spent flower heads you encourage the rose to put its energy into creating new flowers rather than producing seed.
What happens when flowering is over is that pollinated flowers produce a hormone that sends a message to the plant, and the message is ‘we are now going to produce seed’. This is not what we want.
This is only true for the repeat flowering types, and if you want rose hips for their decorative value, them you will not deadhead at all.
- It also tidies up the plant, so the garden looks better.
