Leaftide, a solo‑built garden planner, tackles a long‑standing flaw: most apps rely on generic USDA zones or California defaults, leaving UK growers guessing. By sourcing local frost dates from NOAA, the tool delivers planting windows that match Manchester’s chillier spring, preventing crop loss for seasonal vegetables every year.

Beyond frost, Leaftide integrates Growing Degree Days and photoperiod checks, turning a simple lookup into a multi‑constraint optimization. Users see green, yellow, or red slots, so they plant tomatoes, onions, or fruit trees at the precise moment that balances heat, light, and temperature tolerance for garden success every season year.

The real revenue driver, however, is permanent plants tracking. Apple and berry trees require yearly pruning, bud‑break alerts, and harvest forecasts—features that keep users logged in month after month. Six paid customers, all from Reddit, rely on this ongoing insight to manage their gardens effectively and grow profits.

Built on Django with HTMX for most interactions, the app keeps server‑side rendering lightweight while a custom SVG layer powers the drag‑and‑drop plot designer. Future plans include a mobile app, expanded plant library, and community sharing, but the next hurdle remains: scaling marketing beyond niche forums and growth.
