How it works

Three steps from seed pile to plan.

  1. Draw your beds.

    Add a bed and give it a width and length in feet, up to 12 × 12. New beds start at 4 × 4, the size most people build.

  2. Tap squares to plant.

    Pick a crop from the library and tap the squares it goes in. Each one shows how many fit: 1 tomato, 4 lettuces, 9 beets, 16 carrots.

  3. Set your frost date.

    Type in your last spring frost date. Plotwise counts the weeks back and forward and dates every job for the crops you planted.

The calendar

Your frost date, turned into a to-do list.

Every crop has a window measured in weeks from the last frost. Tomatoes go in indoors 8 to 6 weeks before it. Carrots are sown straight into the bed in the 3 weeks before it. Plotwise does the counting and shows you what is due now.

What it does

Small, careful, and only what you need.

  • 23 crops, spacing already worked out.

    Vegetables, herbs and a marigold, each with how many fit in a square. Filter by name to find basil in a keystroke.

  • Colour by family.

    Brassicas blue, roots amber, legumes teal. You can see your rotation at a glance.

  • Counts you can shop with.

    Every bed totals its plants per crop, so you know how many seeds or seedlings to buy.

  • Saves itself.

    Your garden lives in this browser and saves after every change. No account, no server, nothing to lose.

  • Built for the phone in your pocket.

    Plan on the sofa, check it in the garden. Every square is a labelled button, so it works with a keyboard and a screen reader too, in light or dark.
