Knockout Rose New Growth Burgundy Red: Normal or Problem?

A several-year-old Knockout has burgundy-colored new leaves instead of green after spring pruning. Gardener asks if something's wrong.

Normal for Knockouts

Knockouts typically have:

  • Reddish stems
  • New growth: reddish → reddish-green → green
  • Darker red new leaves in cool spring weather

Weather, fertilizer, and soil affect intensity. This is normal seasonal coloration.

When to Worry

If new growth is bright, intense red (not burgundy/reddish) and leaves are distorted, it could signal:

  • Herbicide drift damage
  • Rose Rosette Disease (RRD)

Your description (burgundy, otherwise healthy) = normal. Enjoy the spring show.
