Site information & safe use

Use the guides to plan and ask better questions about your lawn. A website cannot inspect your soil, identify every symptom or establish that a treatment is suitable for your property.

General guidance and local decisions

Our articles, calculators and printable sheets provide general educational information. They do not promise a particular lawn result, diagnose a property or replace a qualified local professional. Grass cultivar, soil, climate, drainage and recent treatments can change what is appropriate. Monthly calendars are reminders, not instructions to apply a product every month.

Products, tools and treatment safety

Before using a pesticide, read and follow the current label for the exact product, target, site and grass. Follow applicable state and local restrictions, required protective equipment, weather limits and re-entry instructions for people and pets. Do not use a guide or calculator to override a label. The EPA explains the legal role of pesticide labels.

Follow fertilizer restrictions and soil-test recommendations. For machinery, follow the manufacturer's safety instructions, including shutdown procedures before maintenance. Locate irrigation lines and underground utilities before work that could damage them. Seek local Extension or professional help when the problem or safe method is uncertain.

Affiliate links and independent research

As an Amazon Associate I earn from qualifying purchases. Paid links support the site. Research-based comparisons are not hands-on testing, and a stock photograph does not imply that the person, property owner or pictured brand endorses this website. Product availability, specifications and seller terms can change. Amazon purchases and customer service are handled by Amazon or the relevant seller.

Images, sources and reuse

Photography, font and map sources are listed on the credits page. Third-party assets keep their own license terms; their appearance here does not grant unrestricted rights to reuse them. Research citations identify the source of guidance, not sponsorship or endorsement by a university or agency.

Accessible alternatives

The monthly calendar and worksheet information is also provided in the guide's HTML text. Downloading a PDF is optional. The site includes a skip link, labeled controls and a state list alongside the map. If a control or document creates a barrier, report the page and the difficulty so it can be investigated.
