Garden Planning Tools

All four tools below run entirely in your browser - nothing you enter is sent to a server, no account is required, and each one reads from the same structured crop and companion-planting dataset that backs the written pages on this site, so a tool's answer and a page's written explanation can never quietly disagree.

The Companion Pairing Checker

Pick any two crops and get an instant answer: a documented beneficial pairing, a documented antagonist relationship, or a neutral result if we don't have a specific recorded relationship between them. This is the fastest way to settle a specific "can I plant X near Y" question.

The Planting Calendar Generator, Bed Layout Helper, and Frost-Date Lookup

The Planting Calendar Generator builds a zone-specific, shareable sowing calendar from a crop list. The Bed Layout Helper arranges a full crop list into a bed of your exact dimensions while honoring companion-planting relationships automatically. The Frost-Date Lookup reports typical historical frost ranges for a zone - explicitly a historical range, not a forecast for the coming season.

Why Client-Side, Not a Backend Lookup

Building these tools to run entirely in the browser rather than calling a server on every interaction keeps them fast, keeps them working even on a slow connection, and means nothing you type or select ever needs to leave your device. It also means the tools stay in sync with the written pages automatically - both are built from the same underlying data file, generated once when the site is built, so an update to one is an update to both.

No Account, No Data Collection

None of the four tools require you to create an account, sign in, or provide an email address to use them fully. Whatever you enter - crop selections, bed dimensions, a zone choice - stays in your browser tab and disappears when you close it, unless a tool specifically offers to encode your inputs into a shareable URL, in which case the data lives in that URL itself rather than in any database we maintain.

Each tool page also carries its own written explanation of exactly how its result is calculated, so you're never left guessing why a specific verdict or schedule was produced - the reasoning is documented alongside the tool itself, not hidden behind the interface.

New tools are added the same way new pages are - only once genuinely built and tested, never as an empty placeholder card sitting on this hub ahead of time.
