Watergrass and Foreign Grass Weed Control

In this video Randy discusses how to deal with Watergrass.

Key Points:
1. Watergrass usually shows up in newly planted sod when the temperature is above 85 degrees.
2. If you continue your regular maintenance program the first frost will kill off the watergrass.
3. Crabgrass controlling pesticides with the chemical Quinclorac are effective on Watergrass.
4. Spot treating the areas that have watergrass is recommended.

    You have several options. If you don’t care about using chemicals, round-up is a chemical that you can find at your local garden center that will completely kill everything if applied properly. If you want to do it the green way, place several layers of newspaper over the vegetation you want killed. Eventually, everything growing in the area will suffocate and die due to the lack of air. Also, keeping the newspaper soaking wet will speed this process up. You may also want to place something heavy on top of the newspapers so they don’t get blown away. In a few weeks, lift up part of the newspaper and see if everything is dead. If it isn’t, leave the newspaper there for a few more weeks. After this is done, you’ll need to start adding organic matter to the soil. Examples of this include table scraps (but NOTHING with meat or oil of any kind), grass clippings, tea bags, coffee grounds, orange peels, etc. Overtime the organic matter will break down in the soil, and vegetables LOVE soils rich in organic matter. If you want more info on this, just google composting . There’s TONS of info on this.

    Samantha, thank you for your response. Those are great suggestions for controlling weeds and being completely green. The Bayer Lawn Weed and Crabgrass Killer will target broad leaf weeds without killing the bluegrass, whereas the Round-Up kills all plants that it touches. The Bayer Lawn Weed and Crabgrass Killer will take about 24 hours before you start seeing results.

    I was wondering what that little menace was called. I just placed new sod in my yard, and I discovered what I thought was a type of crabgrass – but it was actually watergrass it seems. Excellent tips, and good to know that it should die off after the first frost.
