Weed seed in grains?
I have to be honest. I am seriously considering abandoning my organic lawn care efforts.
This will be my 3rd year using organic fertilizers(SBM, Corn Gluten,Cornmeal,compost teas, etc.), and with each passing year my lawn is becoming filled more and more with crabgrass,quack grass, and other unwanted weeds. I never seemed to have this problem when using Scott's. My question is this, is it possible that weed seed may be mixed in with the grains when they are being harvested?? Is there an organic method to ridding my lawn of this ugliness?
