Aspen Root Suckers: Mow, Don't Spray; Try NAA

Four aspens send up lawn suckers; roots surface in grass. How to stop?

Reality

• Aspens sucker prolifically from roots.
• Herbicides on suckers → kill parent tree (shared roots).

Options

1. Mow regularly in lawn—simplest.
2. Sucker Stopper (NAA) on suckers in beds—suppresses regrowth.
3. Cover roots with 2″ sand to reduce sprouting + protect from mower.

Bottom Line

Mow lawn suckers. Use NAA in beds. Never spray herbicide on aspen suckers.
