White Suckers on 'Don Juan' Rose: Rootstock Taking Over

White flowers on a red 'Don Juan' climber indicate rootstock suckers. Prompt removal prevents the vigorous understock from overtaking the grafted variety.

Why It Happens

All grafted roses have a rootstock (often 'Dr. Huey' or multiflora). Suckers emerge from below the graft union, producing different flowers.

Effective Removal

1. Dig to expose sucker origin
2. Yank downward sharply to tear off at root—removes dormant buds
3. If tearing impossible, cut as close to root as possible
4. Monitor next spring for regrowth

Climber-Specific Note

Vigorous climbers like 'Don Juan' often produce suckers. Regular inspection and prompt removal maintain the desired variety.

Don't let the white-flowered imposter steal your 'Don Juan's' glory.
