So this is probably the "brand name" - only they don't have 50 pound bags for sale? So...
Ah that's GRANULES - that's what he said the first time I called him. Now he was claiming it was just a free corn gluten meal as powder. And then he said "crumbles" was preferred to the powder!
The granules is cheaper so -- also I got skeptical that he even knew what his product was!

So this says because of the Starch Binders in the granules - it takes up to 5 rains to break the stuff down.
So it needs to be applied early.
But he's saying he gets it as meal just as powder or as "crumbles" - which is the granules that are broken down again.

An office in Wisconsin!
So he says he gets a TON of it and this place sells it as a ton. That's 40 bags!
$1240 per ton (40x50# bags)

My question is - is this granules or what? The bag does not say.
OK I emailed them.

This is pricier - and again doesn't say....
Maybe cuz they're down in Virginia - not Corn Country in the upper Midwest.

There image shows a powder and then says "out of stock."
Here's another one - powder as 50 lb bag.
If soil temperatures and biological activity are low, the allelopathic effects can last up to 6 months.
Allelopathy is a biological phenomenon by which an organism produces one or more biochemicals that influence the germination, growth, survival, and reproduction of other organisms.
fancy word!
Yeah that's from California! haha.

So this is also a "powder" and ships out of Wisconsin - so 50 lb bag.
OK so if I ordered that myself - it would be a SpeeDee delivery for $110 - and a major pain for the delivery person. haha. 500 pounds!!
So it would be over $30 a bag. I think the local price is about the same if I wait for the local Feed Mill to order a pallet of 40 bags.
Only he said April - but he said he'd talk to his delivery person next week. So hopefully soon.
And lastly, Crabgrass...It is eventually coming..! Crabgrass is a warm season grass andthis year the soil temperature will take longer to heat up. We will monitor the soil temperatures and send out an email when it is time to apply crabgrass preventer.
2013
If your yard had problems with crabgrass or other annual weeds, apply a pre-emergent herbicide when the soil temperature reaches 50 degrees. Be sure to watch your email for a notice from Steve when it is the right time to apply.Save money on your purchase with the coupon below.Try a corn gluten meal product if you prefer an organic option of control. A 50# bag with 9-10% nitrogen will cover 2500 sq. ft. Both products need to be watered with ¼ -½” of water shortly after applying for best effectiveness
OK this makes me feel a bit more comfortable.
2014 newsletter May
So he stocks it in April every year and has a $1 off coupon for up to four bags.
The mill has 50# bags of Crabgrass Preventer available. Try a corn gluten meal product if you prefer an organic option of control. A 50# bag with 9-10% nitrogen will cover 2500 sq. ft.
OK so when he told me it's "crabgrass preventer" - he remembered the name wrong. That's NOT the Corn Gluten Meal but their synthetic chemical product.
So the coupon is for the synthetic chemical stuff.
Either product can be distributed using any type of fertilizer spreader. The powdery meal is a bit messy to apply, especially on windy days. The granules are easier to spread and much less messy, but they don’t cover the ground as well, which reduces the product’s effectiveness for weed control. For maximum effectiveness, the meal is the best choice for your lawn.

One problem with Corn Gluten Meal can be too much water. Some is helpful, but too much can spoil the job.
Corn Gluten Meal needs to be watered in within 5 days of application. If no rain occurs within that window, you should water it in with 1/4 inch of water. But heavy rain or excessive irrigation will wash it away before it can dissolve into the soil. This means that the watering-in process must also be followed by a dry period of a day or two to prevent the seedling from growing another root. If heavy rain is predicted, it may be best to wait for drier weather before putting it down.
You may prefer to water your lawn before you apply Corn Gluten Meal — especially if you plan to use a broadcast spreader. Being a fine powder, Corn Gluten Meal easily blows around, getting on you and everything else in your yard. Broadcast spreaders cause the powder to fly out to the sides, rather than just dropping straight to the ground, which encourages more mess. Windy days are also problematic. Watering lightly first will help keep the dust to a minimum and make it stick to the lawn immediately.

Studies were made to see if applying only the peptides could do the same thing without the cornmeal. Unfortunately the peptides by itself do not persist in the soil long enough for effective weed control. Current research is being done to see if the peptides can be isolated and then packaged in a form where they can be sprayed with better results.
Timing of the application is important for corn meal to work. Corn meal must be applied before the weed seeds germinate. Corn gluten works on seeds not established plants. It will not kill a dandelion plant.
Corn gluten works on a variety of broad leaf and grass seed weeds. Crabgrass is the primary target, but it also helps inhibit dandelion and clover at time of germination. Since it contains 10% nitrogen, it helps with the greening of grass. It can also be used as a weed and feed, which means that it both kills germinating weeds and stimulates the growth of established plants.
Corn gluten meal is applied at the rate of 20 - 40 lbs per 1000 square feet of lawn. Thus, one 50 lb bag would cover about 2500 square feet of lawn. Once applied, the corn gluten meal should be watered in if there is no rain. Once watered, you must allow the area to dry for 2 - 3 days. Plants need dryness for corn gluten to effectively kill emerging weeds. If excessive rains occur, reapplication may be needed.

OK I discovered this Growing Degree Days tracker website
So from last year - then it definitely needs to be put down in April - and NOT May.
