When to Pick Tomatoes: Harvest Date Calculator & Ripeness Signs

Enter when you transplanted and what you are growing, and get your expected first-harvest window plus the four signs that a tomato is truly ready to pick.

Find your harvest window

Days to maturity on a seed packet counts from transplant, not from sowing. Cool weather stretches it; steady warmth shortens it. Your real window can shift a week either way.
When to pick tomatoes comes down to counting and checking: count your variety’s days to maturity from transplant day to find the window, then check the fruit itself for full color, slight give, ripe smell, and an easy release from the vine. Once a tomato shows its first blush of color it can finish ripening on your counter with no loss of flavor, which is exactly how you outsmart squirrels and split skins.
