Stopping Invasive Rose Suckers in the Lawn: Rootstock Takeover

When the Rootstock Becomes a Weed

A rose bush sends up "growth shoots" underground that surface in the lawn, creating a prickly mess. The gardener wants to control spread.

Why This Happens

Grafted roses use vigorous wild rose rootstocks (often Rosa multiflora or 'Dr. Huey'). If the top variety dies or stresses, the rootstock suckers aggressively. Even an inch of root can generate a new cane.

Control Method

1. Paint herbicide (Roundup/glyphosate) on sucker leaves with a brush—avoids killing grass.
2. Apply in spring during active growth for best translocation to roots.
3. Repeat as needed—suckers may re-emerge from same root fragments.

Persistence wins. The rootstock will eventually exhaust its reserves.
