Editorial standards and corrections

Maintained by Aleksandr Gulbickij · Last updated 8 October 2026

What we publish

1. Calculated pages (places and when-to-plant pages). Every date and number on them is computed from historical weather data and published crop requirements, using the method on our methodology page. We don't hand-edit numbers on individual pages; if a number is wrong, we fix the data or the rule, and every page it affects changes together.
2. Written pages (grow guides, explanations, this policy). These are written and edited by people. Shared climate and method sources are on Methodology; per-guide citations are being added.

Our standards

• Sources first. Plant requirements come from extension services, seed-trade tables and peer-reviewed studies. We cite shared climate sources on Methodology and plan to list sources on each guide. Where we borrow a value from a related plant, we say "proxy".
• Say what we don't know. Pages show the data period behind them. Where data are thin or checks fail, the page is not published in search.
• Typical, not guaranteed. Dates describe what usually happens in the sample we have. We tell you how often the weather does something different when we can.
• No invented experts. Anyone named as author or reviewer is a real person who did that work on that version of the page.
• Dates are honest. "Last recalculated" or "Updated" changes only when the content changed. We never refresh a date to make a page look new.

How we use automation and AI

• A computer program calculates every date, window, chart and table on calculated pages, and fills short template sentences with those results. People design and check the program; see the methodology.
• We do not use AI to generate frost dates or planting windows. Where AI writing or image tools help draft grow guides or illustrations, a person checks facts against cited sources before publishing. Exact tools and scope will be named here as practice settles.
• If you think something reads as made up or wrong, tell us — see below.

Corrections

• How to report: use "Report a problem" on calculated pages, or write to alex@planandplant.garden. Tell us the page, what looks wrong, and (for frost dates) what you usually see in your garden.
• What happens: we reply as soon as we can. If we confirm an error, we fix it, and if the fix changes dates or advice, we record it in a changelog when that page exists. Small typos are fixed without a log entry.
• Local differences: if your garden is consistently earlier or later than our dates, that may not be an error (see Limitations on the methodology page), but we still want to hear about it.
