When to Harvest Eggplant (Signs It's Ready)

The harvest window above comes from the days-to-maturity range for eggplant. The rest of this guide is how to read the cues, cut the fruit clean, and keep it.

Days to maturity by type

The calendar gets you in the neighborhood. Clemson Extension puts eggplant at 65 to 80 days after transplanting, depending on the variety. Start from seed instead, and it runs 100 to 120 days.

But the day count is the start of the window, not a finish line. Eggplant is picked young, so the size you are aiming for depends on the type you grew.

Iowa State Extension starts harvest when globe fruit reach about 2 inches in diameter and keeps picking up to 4 to 6 inches across. Smaller is tender. Bigger gets seedy.

How to tell it's ready

The skin tells you the truth before the calendar does. Check three things.

• Glossy skin. A ready eggplant has smooth, shiny, reflective skin. Penn State and UMN Extension both say to pick while the skin is still shiny and firm. Once it goes dull, you waited too long.
• The press test. Press the side gently with your thumb. Clemson Extension says that when the indentation springs back, the fruit is ripe. If the dent stays, it is overripe.
• Full color, before dull. The fruit should show full, even color for its type, but the surface should still gleam. Bright and glossy is ripe. Flat and dull is past it.

If you are not sure, pick it. Eggplant is best eaten young, so erring early costs you nothing.

How to harvest eggplant

Do not pull or twist. The stems are woody, and yanking tears the plant.

University of Minnesota Extension says to clip the fruit off with sharp shears, not pull it, because pulling damages both the fruit and the plant.

1. Use pruners or a sharp knife. Cut the stem cleanly. Penn State Extension calls for a hand pruner or sharp kitchen knife.
2. Leave about an inch of stem. Iowa State Extension says to leave an inch of stem on each fruit, with the green cap (the calyx) attached. The fruit keeps better that way.
3. Wear gloves. The stems are bristly and the plant has small spines. Penn State Extension suggests garden gloves while you cut.

Harvest about once a week, sometimes twice in a warm spell, so nothing oversizes between picks.

Pick young, and keep picking

Two reasons to stay ahead of your eggplant.

First, young fruit tastes better. Penn State Extension warns that overmature fruit turns dull, the seeds go hard and brown, and the flesh becomes pithy and bitter. Iowa State agrees that overmature eggplant is dull, seedy, and tough. The window for good eating is when the fruit is still firm and shiny.

Second, picking keeps the plant working. As long as you keep removing ripe fruit, the plant keeps setting flowers and new eggplant. Let one fruit oversize on the vine and the plant slows down.

Store the fruit cool, not cold. Clemson Extension holds eggplant at about 45 to 50°F with high humidity. A standard fridge runs colder than that and can cause chilling injury, which pits and softens the skin. Use the warmest part of the fridge and eat it within a week.

Get the spacing right next year

Crowded eggplant sets fewer, smaller fruit, and the plants shade each other into a slow, mildewy mess. Give each plant room and it sizes up fruit you can actually catch at the glossy stage.

Set eggplant about 18 inches apart in rows 30 inches apart, one plant per square foot in a square-foot bed. The how far apart to plant eggplant guide has the full table by method, and the Plant Spacing Calculator shows how many fit your bed. Deciding what to plant nearby? Eggplant companion plants sorts which neighbors help and which are just garden folklore.

Eggplant is one fruit in a summer rhythm. The same press-and-color cues guide when to harvest peppers, which share the same bed and the same firm-and-glossy logic.

Your next step

Eggplant is ready when the skin is glossy and firm and springs back to a thumb press, somewhere in the 65 to 80 day window. Cut it with pruners, leave an inch of stem, wear gloves, and store it cool but not cold. Pick young and keep picking.
