Succession Planting Calculator

Plan repeated sowing rounds for quick crops without scheduling a final round that is unlikely to mature before frost.

How it works

The method

The calculator starts from the crop’s first valid sowing date, spaces rounds by its typical succession interval, and stops at the latest plausible sowing date.

Worked example

Radishes might be sown every ten days through the cool part of the season, while a long-season tomato receives only one round.

Remember: Garden outputs are planning ranges. Weather, cultivar, soil, pests, sunlight, and care can materially change the result.

Common questions

Before you act on the number

Do all crops benefit from succession?

No. Long-season crops often occupy the space all season; the tool clearly reports one round.

Does the tool account for summer heat?

Only through broad crop guidance. Heat-sensitive crops may need a spring pause and a fall restart.

How many plants go in each round?

The result splits your target count across the feasible rounds as evenly as practical.
