Tips for using this calendar

→Today's date is on every bar

Each card has a tiny timeline showing the planting window (green) and harvest window (orange). The dark vertical line is today — so you can see at a glance whether you're early, on time, or past the window.

→Stagger your fast growers

Anything that ripens quickly (radishes, lettuce, arugula) is begging for succession planting. Plant a fresh row every 2 weeks while their window is open and you'll harvest continuously.

→Indoor starts shift these dates

If a plant takes 90+ days, you'll typically start seeds indoors 4–6 weeks before your last frost. The dates here are for direct outdoor sowing — the full plant guide tells you when to start indoors.

→Numbers are best-case

Cool weather, low light, or cramped roots can push harvest dates 20–30% later. Watch the plant, not the calendar — it'll tell you when it's ready.
