Every guide on Weeds in Gardens is meant to be accurate, specific and safe to act on. This page explains where our information comes from, how articles are written and checked, and how we handle corrections.
1. Where our information comes from
- University extension services, for example Purdue, NC State, Penn State, University of Maryland, Clemson HGIC, Oregon State, UC IPM and Kansas State.
- Government agencies such as the USDA, EPA and state invasive-species programmes.
- Herbicide product labels. Rates, timing, temperature limits and turf-safety information always come from the label, because the label is the legal instruction for use.
- Peer-reviewed research in weed science, turfgrass science and plant physiology.
Key sources are linked in each article and listed under “Sources”. We do not cite a source for something it does not say, and we never invent studies, statistics, quotes or test results.
2. How we write
- Answer first. The opening paragraph answers the question directly.
- Identify before you treat. Weed guides start with identification features and common look-alikes, because the wrong ID leads to the wrong treatment.
- Least harm first. Cultural, mechanical and preventive options are explained alongside chemical control, with the pros and cons of each.
- Region and season. When advice depends on grass type, climate or time of year, we say so.
- Plain language. Technical terms are explained the first time they appear.
3. Herbicide and safety content
We describe herbicides by active ingredient rather than promoting brands. We always tell readers to read and follow the product label and local regulations, and we note risks to turf types, ornamentals, pets, children, pollinators and water. We do not recommend household chemicals, such as bleach or salt, that are unsafe or not approved for weed control.
4. Edible, medicinal and toxic plants
Some guides mention traditional or culinary uses of plants. This is general background, not medical or nutritional advice. We never recommend eating or using a wild plant based on identification from a website, and we flag toxic look-alikes. See our Disclaimer.
5. Images
We use our own photographs, original charts and diagrams, and openly licensed photographs (Creative Commons or public domain). Third-party photos are credited in the caption with a link to their licence. Images used for identification show the actual species named.
6. Use of AI tools
We sometimes use AI tools to help organise research and prepare drafts. Facts, numbers and recommendations are checked against the cited sources, and the author is responsible for everything published on the site.
7. Updates and corrections
We revisit articles when new research or product-label changes appear, or when a reader reports a problem. If you find an error, please email contact@weedsingardens.com with the page address and, if possible, a source. We correct confirmed errors promptly.
8. Independence
We do not accept payment for recommendations. The site may show advertising; advertisers have no influence over what we write. See our Advertising Disclosure.
