Not an official site
We are not affiliated with, endorsed by or connected to USDA, NOAA, any state cooperative extension service or any university. We cannot answer soil or pest questions specific to your property or issue official recommendations. For those, use your local extension office. The names of agencies and universities appear only to identify what we describe.
General information, not professional advice
Our pages summarize public timing data in plain language. They are general information, not professional horticultural, agricultural or business advice, and reading them does not create a professional relationship. For advice about your own soil, site or climate, speak to your local cooperative extension office.
Averages, not a forecast
Frost dates and planting windows are long-run averages from public climate data. Any single year can be earlier or later, and your yard's own microclimate (elevation, wind, nearby structures) can shift things further. Each guide shows the date we last compared it with its sources and links to them, but we cannot promise that a page is current on the day you read it.
Advertising and links
The site may show advertising and links to other websites. We do not control them and do not endorse the advertisers or the sites they lead to.
How pages are made
We use AI tools to help research and draft pages. A person checks each page against its official sources and approves it before publication. Read more in our editorial policy.
Limitation
Your use of the site is at your own risk, subject to our terms of use.
