How we source, verify, and correct.

Research-based guides

Every guide on Lawn & Loam is a research-based decision framework, not a product review. Key facts are checked against public, verifiable sources: product labels, manufacturer specifications, EPA guidance, USDA materials, and state Cooperative Extension resources. Each guide records its sources.

What we do not publish

We do not publish invented field tests, fabricated reviews, unverifiable claims, or content written to rank for keywords without supporting evidence. Chemical product guidance follows label and regulatory frameworks rather than brand endorsements.

Corrections

When a material error is found, the guide is corrected in place and its review date is updated, so that the page you are reading matches the current label, specification or seasonal guidance. A correction that changes a recommendation is written into the reasoning rather than quietly swapped out.

Independence

Advertising is kept separate from editorial content and labeled. No advertiser reviews a guide before publication, and no commercial relationship decides which products, methods or seasonal tasks are covered.

Corrections

If a source changes, a label is updated, or we find an error, we update the affected guide and note the change date. For corrections, use the contact page and include the page address and the source to check.

Advertising independence

Advertising is separated from editorial content and does not influence what we publish. If we ever add affiliate links, they will be disclosed clearly on the affected pages.

Sourcing follows the decision a page supports. A mower page leans on manufacturer specifications because width, cutting height and power source are what narrow the choice. A feeding or weed-control page leans on the product label and on regulatory material, because rates and permitted uses are set there rather than by preference. A seasonal page leans on regional material, since a calendar that suits one grass type and climate will mislead in another.

Verification means matching a claim to the kind of source that can settle it. Where a number appears, the page is checked against the specification or label it came from. Where a practice is described, it is checked against published guidance from an agency or an extension service rather than against another website that repeated the same claim.

Corrections are folded into the text. When a recommendation changes because a label, a specification or a seasonal window has been revised, the reasoning around it is revised too, so the page reads as one consistent explanation. A reader who saved an earlier copy should treat the current page as the version in force.

Independence is a matter of what does not happen. No advertiser reads a page before publication, no commercial relationship determines which tasks or products are covered, and advertising is placed away from the guide body and labeled. Where a page mentions a product or a brand, it does so to identify the subject of a comparison rather than to recommend it.

Two limits are stated openly. The site does not run its own field trials, so nothing is described as a test result. And general guidance cannot account for a specific soil, slope or local rule, which is why pages direct those questions to the label, the manufacturer or the extension service that can answer for a particular property.
