How To Harvest Arugula Lettuce

You can harvest arugula lettuce by cutting the outer leaves first and letting the inner ones keep growing.
 
This “cut-and-come-again” method keeps your arugula lettuce plant producing for weeks instead of just once.
 
Whether you’re growing arugula lettuce in a garden bed, a raised planter, or a windowsill pot, the harvest rules stay pretty much the same.
 
So if you’ve been wondering how to harvest arugula lettuce the right way, you’re in the right place.
 
In this post, we’ll walk through when to harvest arugula lettuce, the best techniques to use, and how to keep those peppery leaves coming back again and again.
 
Let’s dig in.
 

When to Harvest Arugula Lettuce

Timing matters more than most people think when you harvest arugula lettuce.
 
Here’s how to know your arugula lettuce is ready:
 

1. Watch the Leaf Size

The best time to harvest arugula lettuce is when the leaves are about 2 to 4 inches long.
 
Baby leaves at this stage are tender, mild, and perfect for salads.
 
If you wait too long to harvest arugula lettuce, the leaves get tough and the flavor turns sharply bitter.
 

2. Count the Days

Arugula lettuce grows fast, usually ready to harvest just 30 to 40 days after planting.
 
So if you planted a few weeks ago, it’s probably time to start checking your arugula lettuce for readiness.
 

3. Harvest Before Bolting

When the weather heats up, arugula lettuce sends up a flower stalk, which is called bolting.
 
Once arugula lettuce bolts, the leaves turn bitter and the plant stops producing tasty greens.
 
So harvest arugula lettuce early in the morning before the heat sets in, and definitely before you see flower buds forming.
 

How to Harvest Arugula Lettuce the Right Way

Once your arugula lettuce is ready, the actual harvest takes just minutes.
 
Here’s the step-by-step approach:
 

1. Snip the Outer Leaves First

Start by harvesting the outer leaves of your arugula lettuce, leaving the center rosette untouched.
 
Use clean scissors or garden shears to cut about an inch above the soil line.
 
This way, the inner leaves of the arugula lettuce keep growing and you get a second harvest in no time.
 

2. Try the Cut-and-Come-Again Method

If you want a bigger haul, cut the entire arugula lettuce plant down to about 1 to 2 inches above the crown.
 
Don’t worry, this isn’t the end of your arugula lettuce.
 
Within a week or two, fresh new leaves will sprout right back up, ready for another round of harvesting.
 

3. Pick Leaves Individually for Baby Greens

For the most tender arugula lettuce, pluck individual outer leaves by hand when they’re small.
 
This keeps the plant stress-free and lets you harvest arugula lettuce continuously over a longer season.
 

4. Harvest in the Cool of the Day

Always harvest arugula lettuce in the early morning or late evening.
 
The leaves are crispest then, and your arugula lettuce will stay fresh longer after picking.
 

5. Avoid Pulling the Roots

Unless you’re clearing the bed, never yank your arugula lettuce out by the roots.
 
Cutting leaves instead of pulling the plant means your arugula lettuce keeps producing instead of calling it quits.
 

Tips to Keep Your Arugula Lettuce Producing

Harvesting arugula lettuce is only half the story, keeping it productive is the other half.
 
Here’s how to get more from every plant:
 

1. Water Consistently

Arugula lettuce loves moist soil, so water regularly, especially after you harvest.
 
Dry soil stresses the plant and makes the leaves of your arugula lettuce bolt faster.
 

2. Feed Lightly After Harvesting

A quick dose of nitrogen-rich fertilizer after you harvest arugula lettuce encourages fresh leaf growth.
 
Just don’t overdo it, or your arugula lettuce will grow fast but taste bland.
 

3. Shade in Hot Weather

If summer heat is creeping in, give your arugula lettuce some afternoon shade.
 
Cooler conditions slow bolting and keep your arugula lettuce harvest going strong.
 

4. Sow Successively

Plant a new patch of arugula lettuce every two to three weeks.
 
That way, when one batch starts to bolt, you’ve always got fresh arugula lettuce ready to harvest.
 

5. Store Your Harvest Properly

After you harvest arugula lettuce, rinse the leaves and pat them dry.
 
Wrap them in a damp paper towel, pop them in a bag, and your arugula lettuce will stay crisp in the fridge for up to a week.
 

So, How Do You Harvest Arugula Lettuce?

You harvest arugula lettuce by cutting the outer leaves first and letting the center keep growing.
 
You can also cut the whole plant back to an inch above the crown and harvest arugula lettuce again in a couple of weeks.
 
The key is to harvest arugula lettuce before it bolts, pick in the cool of the day, and keep the soil moist so the plant keeps producing.
 
Do that, and you’ll harvest arugula lettuce from the same patch for months instead of days.
 
Happy growing.
