How Do You Know When Kohlrabi Is Ready To Pick

You know kohlrabi is ready to pick when the bulb reaches about 2 to 3 inches in diameter, which is typically the sweet spot for the best flavor and texture.

That’s the simplest answer, and it’s the one home gardeners rely on most.

If you’ve been wondering how do you know when kohlrabi is ready to pick, you’re in the right place.

The good news is that kohlrabi is a forgiving crop, so you have a bit of wiggle room.

In this post, we’ll cover the visual and tactile signs that tell you when kohlrabi is ready to pick, what happens if you leave it too long, and how to harvest it properly.

Let’s dig in.

Signs That Tell You When Kohlrabi Is Ready To Pick

The most reliable way to know when kohlrabi is ready to pick is by checking the size of the bulb.

But size isn’t the only clue, there are a few other signs that help you nail the timing perfectly.

1. Check the Bulb Diameter

The bulb is the round, above-ground part of the plant that looks like a turnip wearing a leafy crown.

When kohlrabi is ready to pick, that bulb should be between 2 and 3 inches across.

At this size, the flesh is crisp, juicy, and mild.

If you let it grow much bigger than 3 inches, it starts to get woody and overly fibrous.

So if you’re measuring and that bulb is in the 2 to 3 inch range, that’s your green light.

2. Feel the Firmness

Another way to know when kohlrabi is ready to pick is by giving the bulb a gentle squeeze.

A ready-to-pick kohlrabi will feel solid and firm, like a crisp apple.

If it feels soft, spongy, or gives slightly under pressure, it might be past its prime or starting to dry out.

Firmness is a great indicator because it tells you the inside is still juicy and tender.

3. Look at the Leaves

The leaves also give you clues about when kohlrabi is ready to pick.

Healthy, vibrant green leaves indicate the plant is still actively growing.

When the leaves start to yellow or wilt a bit, that can be a sign the bulb has reached maturity and is ready to harvest.

Plus, if you see the bulb starting to crack or split at the skin, that’s another signal that it’s ripe and should be picked right away.

What Happens If You Don’t Pick Kohlrabi In Time?

Understanding when kohlrabi is ready to pick is important because leaving it in the ground too long changes the quality.

1. The Texture Gets Woody

If you miss the window and the bulb grows past 3 or 4 inches, the flesh becomes tough and woody.

That’s a real bummer because the texture goes from crunchy to practically inedible.

The core gets especially hard, and you’ll end up peeling away a lot of it just to find something palatable.

2. The Flavor Turns Bitter

Young kohlrabi has a sweet, mild, almost broccoli-stem flavor.

But as the bulb ages, that sweetness fades and is replaced by a sharper, more pungent bite.

So if you’re aiming for that delicious, nutty taste, you really do need to know when kohlrabi is ready to pick and act on it.

3. The Skin Thickens

Another sign that you’re late is a bulb with thick, tough, and sometimes cracked skin.

Young kohlrabi has thin, edible skin that you can often leave on for snacking.

Older bulbs require peeling, and you’ll be tossing quite a bit of the harvest in the compost.

Best Practices For Harvesting Kohlrabi

Once you spot the signs and you know when kohlrabi is ready to pick, you want to harvest it the right way.

1. Use a Sharp Knife or Pruners

Don’t yank the plant out of the ground by the leaves.

Instead, use a sharp knife or garden pruners to cut the stem just below the bulb.

This leaves the roots in the soil, and it’s a cleaner cut that helps the bulb stay fresh longer.

2. Trim the Leaves Right Away

After you pick kohlrabi, go ahead and cut the leaves off the bulb.

If you leave the leaves on, they’ll draw moisture out of the bulb and cause it to shrivel up quickly.

You can save the leaves and cook them like collard greens or kale, they’re totally edible and delicious.

3. Store It Properly

Freshly picked kohlrabi stores really well.

Place the bulbs in a plastic bag in the crisper drawer of your fridge, and they’ll stay crisp for up to two weeks.

So once you know when kohlrabi is ready to pick and actually harvest them, you have plenty of time to enjoy them.

So, How Do You Know When Kohlrabi Is Ready To Pick?

You know kohlrabi is ready to pick when the bulb is about 2 to 3 inches in diameter, feels firm to the touch, and the leaves are still healthy but starting to show signs of maturity.

The simplest rule is to check the size first, as that’s the most reliable indicator.

Pull one up when it’s around 2 inches and taste it, you’ll see exactly what we mean about the crisp, sweet texture.

Keep checking every few days after that, because kohlrabi can go from perfect to too tough quickly.

So there you have it, your complete guide to knowing exactly when kohlrabi is ready to pick and how to get the best harvest from your garden.

Happy harvesting.
