How this site is sourced and corrected

Cost ranges

Figures are cash-pay planning ranges aggregated from publicly published US cost guides, contractor price lists and marketplace cost pages, then rounded. They describe typical work, not a quote. Where a range is derived from another number — for example, a per-square-foot price multiplied by an area, or a national range adjusted by a state index — the derivation is shown next to the number.

State adjustments use the US Bureau of Economic Analysis Regional Price Parities by State (2023, all items, US = 100). This is a general price index, not a landscaping survey. A modeled range is labelled “modeled” and should not be read as a measured local price.

Technical and horticultural claims

Plant, soil, water and drainage guidance is checked against USDA Cooperative Extension publications, EPA WaterSense and Soak Up the Rain guidance, and state extension services. Each guide lists its sources at the bottom. We do not present a single extension’s recommendation as universal; climate and soil change the answer.

Directory listings

Listings are compiled from public business data: name, address, phone, website, location, public rating and review count where available. Service tags are derived from the categories and wording in the public listing. A listing is not an endorsement, a licence verification or a quality rating. Companies cannot pay to be included or ranked.

Quality gates: a city page requires at least three complete listings, four distinct service tags and a minimum data density; a state page requires at least ten companies. Listings missing an address or phone are excluded from publication. We remove a listing on request from the business or from a person who can show it is wrong.

Corrections

Email hello@landscapingcostguide.com with the page URL and the specific correction. We fix factual errors and update the page's modified date. If a cost range is materially wrong, we revise the range rather than adding a disclaimer.

Advertising and affiliate links

The site may show display advertising and may link to a quote-request partner. Partner links are marked rel="sponsored nofollow"and disclosed at the point of the link. Advertising does not influence cost ranges, rankings or editorial recommendations. We do not sell directory placement.

Authorship

Guides are written by the Landscaping Cost Guide Editorial Team. We do not claim a licensed contractor, landscape architect or horticulturist reviewer unless one has actually reviewed the page, and no page currently makes that claim.
