Garden Planner Tools — Frost, Spacing, Calendar - Sell Project

Garden Planner Tools turns frost dates into a full planting plan: when to start seeds indoors, how many plants fit each bed, which plants grow well together, and a month-by-month calendar — all in the browser, no account, no uploads. What it does: (1) Frost-date calculator — 44 locations (US cities, USDA zones 3–10, UK & EU cities) with average last spring frost, first fall frost and season length; e.g. Chicago: last frost Apr 20, first fall frost Oct 15, 178-day season. Dates are long-term averages, clearly labelled as planning guides, never forecasts. (2) Spacing calculator — 34 vegetables & herbs, ft/m and in/cm toggles, bed-layout grid; lettuce in a 4x8 ft bed = 48 plants. (3) Companion planting guide — good/bad neighbours for all 34 plants, search + check-my-pair lookup. (4) Planting calendar — Mar–Oct table computed from frost dates, printable sheet, CSV export, JSON backup/restore, localStorage garden, demo garden included. Tech: plain HTML/CSS/JavaScript, zero dependencies, zero running costs, no server. 7 pages (home, frost dates, spacing, companions, calendar, how it works, privacy) + sitemap, robots.txt, JSON-LD. Verified locally: 43 automated tests green, static build green. Revenue: $0 — pre-revenue, no traffic yet. The site is not currently deployed. Transfer: full source code + brand assets + build/run instructions (Node: build to dist/, deploy as a static site on any free host). The buyer deploys it. Screenshots (in order): 1. Homepage — hero + dashboard with demo garden. 2. Frost-date calculator — Chicago, 178-day season. 3. Spacing calculator — bed size and plants per bed. 4. Companion planting guide — good/bad neighbours. 5. Planting calendar — Mar–Oct sowing and harvest windows. 6. Bed-layout grid — one square per plant.
