Lawns · Field Notes
The grass slows down on top this time of year. The roots keep working. That is the whole reason to do it now.
Most lawn products are sold on speed. Green in a week. You can see why. It is easy to sell a thing people can watch happen.
Fall does not cooperate with that. Cool season grass is winding down on top no matter what you spray on it. Anything promising you color by Thanksgiving is selling you dye, or selling you a flush of soft growth you do not want heading into winter.
The work happening this time of year is under the ground. That is the reason nearly every turf program in the country treats the fall feeding as the one that counts.
The feeding that matters, and the part that gets wasted
Most people already know to feed in the fall. Fewer people think about how much of that feeding the plant actually ends up with.
A good bit of it never gets in. Some locks up in the soil. Some moves on past the root zone with the first heavy rain. You paid for all of it either way.

That is the whole proposition. Not more fertilizer. More of the fertilizer you already bought.
If you seeded this fall
September and October were the window for cool season seed, and most of that seed went somewhere rough, the thin strip along the driveway, the bare ring under the maple, wherever nothing took last year.
That ground is thin for a reason, and the reason is usually that there is not much organic matter left in it. Which happens to be exactly where humic shows its largest response in the research. On ground that is already rich and well fed, it does less. We would rather say that up front than have you find out.
Put it down over the new seeding. It is not a seed treatment and it was never going to make seed come up. What it does is help the plant get more out of what you already fed it.

What it will not do
It will not green you up by the weekend. This is a soil product. The response builds over seasons, which is the reason to put it down in fall rather than in May.
It will not replace your fertilizer. It is a soil conditioner. Run it alongside your program, never instead of it.
It will not fix your pH. If your soil is sour you need lime, and nothing in a jug substitutes for that.
It will not hold water in your lawn, add meaningful organic matter, or cure lawn disease. We have seen all three claimed. None of them hold up.
And it does the least on good ground. If you soil test, feed on schedule and have been building that lawn for years, expect less from it than someone starting on scraped fill.
Rate and what it costs
One ounce per thousand square feet. It is fully water soluble, so it mixes clean in a hose-end, a pump sprayer or a backpack and will not clog a nozzle. A five thousand square foot yard is five ounces a pass.

We farm in Laurel, Delaware. Fourth generation. We ran into the same wall on our own ground that shows up in a tired lawn. Feeding the crop, ignoring the dirt, and watching more fertilizer stop moving the needle.
So we started feeding the soil instead. We used it on our own ground for years before we ever put it in a jug to sell, and we blend and bottle it ourselves.
The grass stops. The roots don't.
