How to get rid of dollarweed?

Eliminating Dollarweed from Charlotte Lawns

Dollarweed thrives in moist, compacted areas typical of Piedmont region lawns. Its distinctive round leaves and shallow root system make it vulnerable to targeted treatment strategies when approached systematically.

Cultural Control Methods

The most effective approach combines mechanical removal with environmental modifications. Dollarweed indicates moisture problems, so addressing drainage often eliminates the weed naturally.

1. Improve drainage in affected areas through aeration or topsoil additions
2. Reduce watering frequency and apply water only during established schedules
3. Hand-pull small patches, ensuring you remove the entire root system
4. Maintain proper lawn height (2.5-3.5 inches) to shade out seedlings
5. Fill low spots where water collects to prevent weed establishment

Chemical Treatment Options

When cultural methods alone are insufficient, selective herbicides designed for broadleaf weed control in lawns can be effective. Dicamba-based products and MCPA typically provide good dollarweed control without damaging turfgrass.

Multiple applications spaced 2-3 weeks apart often provide better results than single treatments, and tank-mixing with a surfactant improves coverage and effectiveness.
