Juggler thats a good question.

I had intended to spread corn glutten meal on my lawn next march to discourage weeds from germinating.

I would hope that one could take a wire rake or something similar and get it worked down to ground level.

Hopefully some of those in the know will respond.

Corn gluten meal that is marketed for horticultural uses is pelletized or granulated into a consistency similar to corn meal. It can then be spread by hand or with a spreader and is intended to be used directly on turf. The powdered form is typically used in animal feed applications and while cheaper, may not be as effective or efficient in achieving desired horticultural results.

Either form will get to soil level pretty easily if the grass is dry before you put it down, and if you water it in. If grass is wet, the powdery stuff may clump up on grass a bit more.

Cockadoodledoo brand is expensive and a finer powder.

Corn gluten meal will work just fine when applied to turf. It does not matter what form it is in, the granulated forms are easy to spread with a slinger but there is no difference in effectivness. Timeing is the most important thing. Spring applications should be done early, about the time daffodils are blooming. It works best if it is well watered in, then the ground allowed to dry out. Following up with a fall application helps. Keep in mind this is a long ternm type of thing and is most effective after a few years.

Thanks for the help everyone.
