When Are Japanese Eggplants Ready To Pick

Japanese eggplants are ready to pick when they have glossy, deeply colored skin and feel firm to the touch.
 
You’ll know it’s time to harvest Japanese eggplants when they reach about six to eight inches long, though some varieties are perfect at a smaller size.
 
Picking Japanese eggplants at the right moment matters because they can quickly turn bitter and seedy if left on the plant too long.
 
In this post, we’ll cover exactly when are Japanese eggplants ready to pick, how to tell by sight and feel, and what happens if you wait too long.
 
Let’s dig into the best ways to enjoy these slender, sweet beauties at their peak.
 

When Are Japanese Eggplants Ready to Pick? The Simple Answer

When are Japanese eggplants ready to pick? It’s all about size, color, and a little squeeze test.
 
Japanese eggplants are ready to pick once they’ve stopped growing in length and their skin has a shiny, almost mirror-like finish.
 
Unlike larger globe eggplants, Japanese varieties are harvested younger, which is why they’re so tender and mild.
 
You can expect your Japanese eggplants ready to pick roughly 50 to 60 days after transplanting, depending on your climate and variety.
 
But the calendar is just a guide, so let’s break down the physical signs you should look for.
 

1. Check the Length of Your Japanese Eggplants

Most Japanese eggplant varieties are ready to pick when they’re between six and eight inches long.
 
Some slender types, like Ichiban, can be harvested at just four to five inches if you prefer smaller, more delicate fruits.
 
When are Japanese eggplants ready to pick in terms of length? Look for a fruit that’s stopped elongating but hasn’t started bulging at the bottom.
 
A bulging bottom means seeds are forming, which signals over-maturity.
 

2. The Glossy Skin Test

The skin of a ready-to-pick Japanese eggplant should be glossy and taut.
 
If the skin has started to dull or wrinkle, your Japanese eggplants are past their prime.
 
A shiny surface means the flesh inside is still firm and the seeds are tiny and undeveloped.
 
Run your finger over the skin, and if it feels smooth like a polished stone, it’s likely ready to pick.
 

3. The Gentle Squeeze Method

When are Japanese eggplants ready to pick? Squeeze them gently with your thumb.
 
A ripe Japanese eggplant yields slightly under pressure but bounces back immediately when you release.
 
If it feels hard as a rock, give it a few more days.
 
If it feels spongy or leaves a dent, you’ve waited too long and the flesh inside is likely bitter.
 

4. Color Consistency Matters

Your Japanese eggplants are ready to pick when the color is deep, uniform purple (or the expected shade for your variety).
 
If you notice pale patches or streaks, the fruit is still ripening.
 
Also, check the calyx, the green cap at the stem end, it should look fresh and green, not yellow or dried out.
 

What Happens If You Don’t Pick Japanese Eggplants on Time?

If you leave Japanese eggplants on the plant too long, they will tell you loudly.
 
The skin loses its shine and becomes dull or even yellowish.
 
The flesh turns spongy, and the seeds harden into a bitter, crunchy texture that’s unpleasant to eat.
 
Also, overripe Japanese eggplants left on the vine signal the plant to stop producing new flowers.
 
By picking Japanese eggplants promptly, you encourage the plant to keep fruiting all season long.
 

How Often Should You Harvest Japanese Eggplants?

Once your Japanese eggplants start ripening, you’ll be picking them every two to three days.
 
Check your plants daily because these fast growers can go from perfect to overripe seemingly overnight.
 
When are Japanese eggplants ready to pick in a continuous harvest? Just keep an eye on each fruit’s size and gloss.
 

Best Time of Day to Pick Japanese Eggplants

Morning is the best time to harvest Japanese eggplants.
 
In the morning, the plants are fully hydrated, which means the fruits are crisper and store better.
 
Avoid picking in the heat of the afternoon because the fruits may be slightly wilted and less flavorful.
 
Use sharp pruners or a knife to cut the stem about an inch above the calyx.
 
Don’t twist or pull the fruit off the branch, as that can damage the plant and reduce future yields.
 

Storing Harvested Japanese Eggplants

Once your Japanese eggplants are ready to pick and you’ve snipped them, use them within a few days for the best flavor.
 
Keep them at room temperature for a day or two, or store them in the refrigerator crisper drawer for up to a week.
 
Avoid washing them until you’re ready to cook, because moisture speeds up spoilage.
 

So, When Are Japanese Eggplants Ready to Pick? A Quick Recap

When are Japanese eggplants ready to pick? They’re ready when they hit that sweet spot of six to eight inches, glossy skin, a slight give on squeeze, and a deep, even color.
 
Japanese eggplants are ready to pick around 50 to 60 days after planting, but always rely on the visual and tactile cues over the calendar date.
 
You can pick Japanese eggplants a bit early if you love them extra tender, but you really shouldn’t wait past the glossy stage.
 
Harvesting at the right time keeps the flavor sweet, the texture creamy, and your plant productive.
 
So next time you’re in the garden and wondering when are Japanese eggplants ready to pick, just look for that shine and give one a gentle squeeze.
 
You’ll be rewarded with the most delicious stir-fries, grills, and curries all season.
 
Happy harvesting, and enjoy every bite of these lovely, slender purple gems.
