However I'm talking from my experience from doing Countless amount of yards in the past 15 to 20 years. I managed about 8 lawns a day, and worked 6 days a week for all those years. Maybe 5000 mows, I don't know because like I said countless lawns. And that's the reason I know what I'm talking about with Corn Gluten Meal too.
I landscaped for nearly ten years, but at that, your soil and weather, is different from up here.
Most lawn soil up here is good and except for drought years water on average is not a problem.
It is during the drought years Crabgrass sets in and when weather gets better grows like gangbusters every where its seeds exist.
I have never, ever seen a a thick lawn eliminate crabgrass.
It can be in a thick lawn, and people who mow regularly, short, will not see it because they are not looking for it.
Come a drought and their lawn suffers, the Crabgrass will expand and once expanded NOTHING but pulling or poisoning will eliminate it.
The seeds last for many, many years in the soil, waiting for a chance to sprout.
Now there are multiple types of crabgrass THIS I did not know till recently.
Crabgrass Seed
Crabgrass, including the Quick-N-Big and Red River varieties, is one of the highest quality Summer perennial grass varieties available for pasture, hay, and forage in the south. Crabgrass is often considered a weed by many farmers and ranchers, but can be utilized in pasture grazing and hay production if properly managed.
We our normal lawn weed type is a low, very low, grower when amongst other grasses.
When pulling on my hands and knees, I some time have to run my fingers , hard against the ground to get under the leaf stems and suddenly far more stems with seeds pop up that I did not know were there.
In my garden there appears to be two types, one grows low and wide and another will send leaves up over a foot in the air.
