Nº 01A vegetable planting calendar for real gardens

Everyone says “plant after the last frost.”Nobody says when.

Furrow turns your rough corner of the world into real sowing dates — frost-safe planting windows for your zone, so you know when to plant each vegetable — then turns those dates into short, doable tasks. A bed planner, a journal, harvest notes. No feed, no streaks, no guilt.

Nº 02The app

Sunday night, one small list.

The first two screens we’re building. Your planting window up top, a couple of honest tasks below — then you’re done for the day.

Design previews, drawn in code — dates, names and weather are illustrative.

03What it does

Four quiet tools. Nothing that needs feeding.

No social feed bolted on, no gamified watering streaks. Just the things a kitchen garden actually asks of you.

01

Dates with a paper trail

Pick a rough region — a state will do. Every sow, transplant and harvest window is calculated from published climate normals for your zone, and the source is one tap away. When the data can’t be sure, it says so instead of guessing.

02

A to-do list grown from your beds

Sketch your garden in squares — two of tomato, three of lettuce, one bed you keep meaning to fill. Furrow turns that sketch into this week’s short tasks: thin the carrots, harden off the seedlings, skip the watering — it rained.

03

A journal you’ll actually reread

A photo and a sentence a week is enough. Next spring you’ll know the basil bolted in June and which bean earned its trellis. It’s your notebook — nothing posts anywhere by default.

04

Works where the signal dies

Allotments and back fences are not famous for their bars. Your plan, calendar and journal live on the phone — log a harvest with zero service and it syncs when you’re home. No account required.

04The field guide

Plants drawn like we mean them.

No stock photos, no generic green leaf. Every crop gets its own botanical illustration and a season bar for your zone. Try growing one yourself:

Growth study · drag the sliderPlate Nº 00

The same plant, five honest stages — grown by a slider, not a zoom.

Four from the first set: sow / start transplant harvest Zone 5 example — the bars move for your zone.
I

Tomato

Solanum
lycopersicum

Sow indoors six weeks before your last frost. Staked, it repays you into October.

The reason you bought a stake.

II

Lettuce

Lactuca
sativa

The easiest win in the garden. Sow a short row every three weeks and it never leaves your table.

Salad happens to other people.

III

Carrot

Daucus
carota

Slow to start, then smug. Loose soil, patient thinning, and sweetness after the first cool nights.

Thinning is not optional. Sorry.

IV

Basil

Ocimum
basilicum

Wants warmth and pinching. Pinch, and it becomes a bush; don’t, and it becomes a flower stalk.

Pesto is a season-end decision.

05Our promises

Three promises, in writing.

Your town, not your coordinates

The frost math needs a climate region, not your doorstep. Rough region in — never GPS, never your address in logs.

Sharing is a decision, not a default

Sharing a harvest card is a choice you make each time, after a privacy preview. Nothing posts as a side effect of anything.

Guilt is not a feature

Miss a month — life happens, gardens wait. Furrow will never count your absences, dim your streak or send a shame notification.

06Questions

Asked and answered. Honestly.

What is a planting calendar?

It’s a map of your growing season: the average last frost in spring, the first frost in autumn, and the sowing and transplanting windows that fit between them for each vegetable. Furrow builds yours from published climate history for your zone — a reference to plan by, not a forecast to bet on.

Where do the planting dates come from?

Published climate normals — decades of recorded first and last frosts, season length and temperatures for your zone — combined with regional growing rules we license and review. Every window shows its source and version. They’re references, not forecasts; a warm spring will always have the final word.

What can I grow with it?

The first field guide covers kitchen-garden staples — tomatoes, lettuce, carrots, radishes, basil and other herbs — each with sow-indoors, transplant, direct-sow and harvest windows. Tell it your zone and it lists what you can sow this month.

Is my region covered?

The first season covers the US, UK, Canada and Australia — zones from Calgary-cold to Perth-hot. Elsewhere, we’d rather say “not yet” than guess at your frost.

Does it work without an account?

Yes — that’s the point. Plan beds, check tasks, keep a journal, all on the device with zero sign-up. An account only adds backup and syncing across phones, and it’s never a gate.

Does it work offline?

Yes. Beds, tasks, the journal and your zone’s planting windows all live on the device — the app doesn’t even ask for network permission. It works at the plot, where the signal dies.

What will it cost?

Planning, the calendar and the journal are free at launch. Later there may be paid extras — several gardens, say, or exporting a season plan — but the Sunday-night “what do I do this week” list stays free. If that ever changes, this page will be the first place we say so.

When does it launch?

The first release is for Android, on Google Play — it’s out now. iOS is planned later; join the email list and you’ll get one email when it lands in your region — no drip campaign, no “top five tips”.

The first release is for Android and it’s in review right now. Open the store page below — or leave your email and we’ll write once, the day it’s live in your region. No newsletter, no engagement tricks.

Android first. Other platforms when there’s something worth shipping.
