Hand-pull large weeds, mulch all bare soil and work on soil health for overall control. Avoid the toxic chemical herbicides, especially pre-emergent types and those that contain 2,4-D.
 
Use 10% (100 grain) vinegar or stronger at full strength and/or citrus oil as effective organic herbicides on hot days. Be sure to clean vinegar thoroughly out of metal spray parts, it is very corrosive.




Use "The Weeder" or "Lawn Claw" for mechanical weed removal. Apply corn gluten meal in the Spring and Fall to control annual weeds such as grass burrs.  Avoid all SU herbicides and those containing Picloram.
