Product Review (submitted on October 1, 2018):

After researching options for organic pre-emergent fertilizers, it seems corn gluten is really the only choice. It's expensive, but helps to buy a 2- or 3-bag combo. Free shipping is also a nice considering the weight. As for the effectiveness, it was OK in my first year using it. Had lots of clover, that's about it. Not sure this stuff is effective against clover though. I also read that it takes a few applications over a couple years to really build the effectiveness of corn gluten, so I will be re-applying next spring. Overall I'm pretty happy with it. Cost is the only reason to downgrade to 4*
