Removing Grassburrs (Sandburs) from the Lawn

Mechanical Removal of Grassburrs for Pet Safety

Pre-emergent (Amaze) stops new seeds, but existing burrs need physical removal. A lawn vacuum may clog on sticky burrs. Better method:

1. Dethatch first: Use a power rake with metal tines (not knives) to lift burrs and loosen soil surface.
2. Mow with bagger: Immediately mow over the area to collect dislodged burrs.
3. Repeat as needed through the season.

This reduces the seed bank over time. Combine with consistent pre-emergent applications in spring for long-term control.
