Furrow Zones

Type any city on Earth and see exactly what to plant this month — from nursery starts or seed. Built on 10 years of real climate data. Free, private, no account.

One question, answered perfectly: what can I plant right now, right here?

Furrow Zones works anywhere on Earth. Type a city or postal code — Santa Cruz, London, Tokyo, Naxos, Quito — and the app analyzes 10 years of real climate history for your exact spot: frost dates, summer heat, winter chill, and your climate type. No generic zone charts. No guessing.

WHAT YOU GET

• Plant right now — a live list of vegetables, herbs, fruits, and flowers you can plant this month, built for your microclimate • Coming soon — what opens up next, so you can plan ahead • Nursery starts or seed — flip one toggle and every window recalculates. Planting 1–2 ft starts from the nursery keeps crops viable weeks longer than sowing seed; the app knows the difference • Instant answers — search any plant and get a verdict: plant now, plant in October, or not suited to your climate. Never a dead end • Growing hints — practical one-liners for every plant, from soak-your-seed tricks to frost-pocket warnings

BUILT DIFFERENT

Most planting calendars stop at USDA zone charts — fine for average winters, useless for real decisions. Furrow Zones computes your actual last and first frost from a decade of daily data, reads your summer heat to know when it's too hot to transplant, recognizes Mediterranean, oceanic, tropical, arid, highland and continental climates, and flips the calendar automatically south of the equator.

Cool-summer coast? It won't sell you okra. Tropical highlands? Greens year-round, no false promises. Hot-summer south? It knows about fall replant windows. The engine has been validated against real growing calendars across the US, Europe, Japan, Russia, South America, and the southern hemisphere.

WORKS FOR YOU

• 157 crops and flowers, each matched to your climate • US locations get official USDA zone lookups; everywhere else computed from real winters • One-time setup, works offline after that • Free. No account. No ads. No tracking. Your location is used once to find your climate and never stored or shared.

From the maker of Furrow — Garden & Plant ID, the full garden companion with care schedules, journaling, and AI plant identification. Furrow Zones does one thing: it tells you what to grow, where you are, right now.
