Frequently asked questions
How long does onion take to be ready for harvest?+
About 130 days from sowing/transplanting for typical varieties. Use this for planning and confirm readiness with the crop's own maturity signs (colour, size, firmness or Brix).
How do I know onion is ready to harvest?+
Judge by the crop's maturity indicators rather than the calendar alone — size, colour, firmness or sugar (Brix) as appropriate. This planner marks the likely window so you can start checking at the right time.
Can I stagger plantings using this?+
Yes — run the planner for each planting date to spread harvests across the season, smoothing labour demand and market gluts. This is the basis of succession planting.
Is this tool free and private?+
Yes — free, no sign-up, and all calculation runs in your browser, so it works offline in the field and your data never leaves the device.
