It usually isn't the heat
Every year it goes the same way. May and June the lawn looks like a magazine. Then late July turns, the color goes flat, and the thin patches come back in the same places they were last year. You water more. It helps for a day.
Two lawns can sit side by side with the same sun, the same water and the same fertilizer, and one holds through August while the other quits. The difference is almost never above ground.
A lawn with shallow roots is living off the top two or three inches of soil — the first layer to dry out and the last to hold anything. When July gets long, that grass has nothing to reach for. So the real question isn't how to survive August. It's what builds roots in the months before it.

The root-mass figure is from independent published research on humic and kelp applied together — not a trial of Humic+. How much you see depends on your soil, and we would rather tell you that here than after you've bought a bottle.

Is this actually for your lawn?
The single most consistent finding across every study we reviewed is that this works on some soil and does almost nothing on other soil. Here is how to tell which one you have.
Worth it if
- Your soil is tired, sandy or compacted. Response is largest where organic carbon sits under 1% — builder's fill, new construction, or ground that's been mowed and fed for years without ever being built back.
- You already fertilize and want it to go further. Nitrogen use efficiency rose 27% across 479 field observations.
- Your lawn browns out every July. Stressed plants responded around +28% against +18% for comfortable ones.
- You're seeding, overseeding or laying sod. Rooting and post-transplant strength is the most replicated effect in the whole literature.
- You want one jug for beds, trees and shrubs too. Same concentrate, same rate.
Probably skip it if
- Your lawn is already thriving on a good program. Effects shrink toward zero on rich, well-fertilized ground. Publicly funded UC Davis trials found no consistent benefit on fertile soil at commercial rates.
- You need it to look different this week. The hormone response starts inside 72 hours, but the visible change is underground and takes a season.
- You're hoping to stop fertilizing. Humic with no nitrogen fell below acceptable lawn quality on 12 separate rating dates.
- You want it to cure a disease. No peer-reviewed field trial exists for kelp against dollar spot or brown patch.
- Your soil pH is above 8. Efficacy is measurably attenuated in alkaline soil.

Less than you think, more often than you'd guess
1–2 oz per 1,000 sq ft, every 2–4 weeks through the growing season. That is a deliberately small dose: across the dose-response studies we reviewed, the lowest rate was often the only one that helped, and overdosing reduced growth outright. Mixes clean in a hose-end, pump or backpack sprayer, a watering can, or straight into irrigation.
Frequently asked questions
How fast will I see something?
Honestly: not fast, and anyone telling you otherwise is selling you a dye. Hormone-level responses begin within about 72 hours, but the visible change is in the root system. Across the turf literature the recurring pattern is that rooting improves while appearance does not. Judge it in August, not next Saturday.
Will it work on my lawn?
It depends more on your soil than on the bottle — see the section above. Tired, sandy, compacted or stressed ground responds most. Rich, well-fed ground responds least.
Which size should I get?
The 32 oz covers up to 32,000 sq ft — about three quarters of an acre, or a full season for most yards. If your lot is bigger than that, or you also treat beds, trees and shrubs, the 128 oz covers roughly three acres at less than half the cost per ounce.
Can I use more to get faster results?
No, and please don't. Every dose-response study in our review found an optimum with decline or harm above it. In one trial a fulvic acid drench cut tomato shoot weight by up to 74% and caused iron and manganese toxicity. Our rate is deliberately conservative.
What if it doesn't work for me?
Thirty-day money-back guarantee. Try it on your worst patch of yard. If it isn't for you, email us and we'll refund it — you won't have to fight us for it. Keep the bottle.
When will I get my order?
Orders ship free from our farm in Delaware, usually within 1–2 business days, with tracking by email.
Who is Farm Made Organics?
Four generations on the same ground in Laurel, Delaware. We started putting soil amendments down on our own fields long before we ever thought about selling any. We're a farm first. The products came second.
