Plant Growth Chart

Watch your seeds grow — from day one to harvest.

Every plant's lifecycle, drawn to scale. See exactly how long sprouting takes, when growth picks up, and how long the harvest window lasts.

Fastest in our catalog: Cress (10 days). Slowest: Asparagus (720 days). Most fall somewhere in between.

How to read the chart

Sprouting

From the day you plant the seed until the first leaves break the soil. Usually 5–14 days. Keep the soil consistently moist during this stretch.

Growing

The longest stretch — roots establish, leaves develop, the plant builds the structure it needs to fruit or flower. Water and feed regularly.

Harvest window

The plant is ready and will keep producing for this many days. Pick regularly — the more you harvest, the more most plants produce.

What this means for you

→Plan your season backwards

Pick your target harvest date, count back the days-to-harvest number, and that's when to plant. We do this math automatically once you tell us your frost dates.

→Stagger your fast growers

Anything under 50 days (radishes, lettuce, arugula) is begging for succession planting. Sow a fresh row every 2 weeks and you'll harvest continuously.

→Start slow plants indoors

If a plant takes 90+ days to mature, you'll want to start the seeds indoors 4–6 weeks before your last frost. The growing season isn't long enough otherwise in most of Canada.

→Numbers are best-case

Days-to-harvest assumes ideal conditions. Cool weather, low light, or cramped roots can push these numbers 20–30% longer. Watch the plant, not the calendar.
