Sudden Red Blooms on a Pink Rose: Rootstock Sucker Invasion

10+ year old pink rose bush now blooming red (mostly) with a few pink flowers.

Dr. Huey Takeover

Rootstock (Dr. Huey, red semi-double climber) sent up canes from below graft union. It will take over if left.

Removal

Dig down to where red cane originates. Grasp base and yank downward hard to tear it off (don't cut—cutting encourages regrowth). The wound calluses over, blocking return. Watch for more.
