Planting to Harvest Date Calculator
Search or choose a crop, enter your planting date, and get an estimated harvest window — drawn from the same days-to-maturity figures used across all 149 grow guides on this site.
Every crop on this site has a documented days-to-maturity figure in its grow guide — a range like tomato's 60–100 days, or apple's 2–4 years to first fruit for a young tree. This tool takes that same figure and does the date maths for you: enter when you planted or sowed, and it works out roughly when to expect your first harvest.
Harvest Date Calculator
These are typical ranges from each crop's grow guide, not a guarantee for your specific plant, climate zone, or season — individual variation is normal and expected. This is general growing information, not a substitute for local advice.

Why It's a Window, Not a Single Day
Days-to-maturity figures are typical ranges from growing references, not fixed countdowns — your actual harvest date shifts with your climate zone, the specific variety you're growing, soil, weather that season, and how the crop is cared for. Fast-maturing annual vegetables (a 50–70 day beetroot, say) tend to land fairly close to the estimate. Fruit and nut trees and other perennials (a 2–4 year apple, a 3–5 year almond) have much wider real-world variation, since the estimate there is the time to first fruiting after planting a young tree, not a per-season harvest date — treat it as a rough guide to when to start watching, not a date to circle on the calendar.

Frequently Asked Questions
How accurate is an estimated harvest date?
Treat it as the centre of a window, not a guaranteed day. Actual timing shifts with your climate zone, the specific variety, soil, weather, and how the crop is cared for, so the estimate uses each crop's typical range from its grow guide rather than a single fixed number.
Why do some crops show a harvest date years away?
Fruit and nut trees and other perennials take years to reach their first harvest after planting, rather than weeks or months like annual vegetables. For those, the estimate is the time to first fruiting after planting a young tree or plant, not a per-season harvest date.
Does this work for seedlings transplanted after starting indoors?
Enter the date you actually put the plant in its final growing position (the ground or its final pot), since that's what each crop's days-to-maturity figure is measured from, not the date you first sowed seed indoors.
Where does the days-to-maturity data come from?
The same MATURITY figure shown in each crop's own grow guide on this site, covering all 149 fruits, vegetables, nuts, herbs and grains currently documented.
