When To Harvest Courgettes

The best time to harvest courgettes is when they are young, tender, and about 10 to 15 centimeters long.
 
If you have been wondering when to harvest courgettes, the simple answer is before they turn into marrows.
 
Courgettes grow fast, so you will often find yourself checking the plant every single day.
 
In this post, we will look at exactly when to harvest courgettes, how to pick them, and how to keep the plant producing more fruit.
 
So let’s dig in.
 

When to Harvest Courgettes

Knowing when to harvest courgettes is mostly about size and texture rather than a specific calendar date.
 
Courgettes are usually ready to harvest between 50 and 65 days after planting, depending on the variety.
 
The key is to check your plants daily once they start flowering because courgettes can double in size overnight.
 
If you wait too long, the skin becomes tough and the seeds inside start to harden.
 
So when to harvest courgettes really comes down to picking them while they are still small and glossy.
 

1. Size Is the Best Indicator

The easiest way to know when to harvest courgettes is to look at their size.
 
Most courgettes taste best when they are 10 to 15 centimeters long and about 3 to 5 centimeters thick.
 
At this stage, the flesh is firm and the flavor is sweet.
 
If your courgettes are longer than 20 centimeters, they are technically still edible but they will be watery and full of seeds.
 
So when harvesting courgettes, aim for the smaller ones for the best kitchen results.
 

2. Skin Texture Matters

Another sign of when to harvest courgettes is the skin.
 
A ready courgette has shiny, tender skin that you can easily pierce with your thumbnail.
 
If the skin feels hard or looks dull, you have waited too long.
 
When you harvest courgettes at the right time, you barely need to scrub them before cooking.
 
That soft skin is a clear sign that the courgette is perfect for picking.
 

3. Check the Flower

The flower on the end of the courgette can also tell you when to harvest courgettes.
 
You can pick courgettes while the flower is still attached and open.
 
In fact, many gardeners harvest courgettes at this stage because the flower is edible too.
 
Once the flower wilts and falls off, the courgette is still fine to eat but it is getting older.
 
So if you are unsure about when to harvest courgettes, pick them while the blossom is still fresh.
 

How to Harvest Courgettes the Right Way

Once you know when to harvest courgettes, the next step is picking them without damaging the plant.
 
Courgette plants are prickly and delicate at the same time, so a little care goes a long way.
 
Here is how to harvest courgettes properly.
 

1. Use Sharp Pruning Shears

Never twist or pull courgettes off the vine because you can snap the stem or uproot the plant.
 
Instead, use a sharp knife or pruning shears to cut the stem about 2 to 3 centimeters above the fruit.
 
This clean cut helps the plant heal faster and keeps it producing new courgettes.
 
When you harvest courgettes with clean tools, you also reduce the risk of disease.
 

2. Harvest in the Morning

The best time of day to harvest courgettes is in the cool morning hours.
 
At this time, the fruit is crisp and fully hydrated.
 
If you harvest courgettes in the heat of the afternoon, they may wilt faster on the counter.
 
So plan your picking session early, especially on hot summer days.
 

3. Handle the Plant Gently

Courgette plants have prickly stems and leaves that can scratch your arms.
 
Wear gloves and long sleeves when you harvest courgettes to protect your skin.
 
Also, step carefully around the plant because the roots are shallow and easy to damage.
 
The gentler you are, the longer your plant will keep producing.
 

How Often Should You Harvest Courgettes?

When to harvest courgettes is not a one-time event because the plant keeps producing new fruit all season.
 
You should check your plants every one to two days during peak growing season.
 
The more often you harvest courgettes, the more the plant will produce.
 
If you leave mature courgettes on the vine, the plant slows down and stops making new ones.
 
So regular harvesting is the secret to a constant supply of tender courgettes.
 

1. Pick Small and Often

The golden rule of when to harvest courgettes is to pick them small and pick them often.
 
A courgette that is ready today will be oversized tomorrow.
 
So make it a habit to walk through your garden with a basket every morning.
 
When you harvest courgettes at this pace, you will never end up with a surprise marrow.
 

2. Don’t Let Them Grow Into Marrows

If you miss the ideal window of when to harvest courgettes, the fruit becomes a marrow.
 
Marrows are still useful for stuffing or baking, but they are not the same as tender courgettes.
 
And once a courgette turns into a marrow, the plant often slows down its production.
 
So stay on top of your harvest to keep the plant in high gear.
 

3. Remove Damaged Fruit

While you are checking when to harvest courgettes, look for any damaged or rotting fruit.
 
Remove them right away so they don’t attract pests or spread disease.
 
A clean plant is a productive plant.
 
So when you harvest courgettes, take a moment to tidy up the vine as well.
 

So, When to Harvest Courgettes?

You should harvest courgettes when they are young, glossy, and about 10 to 15 centimeters long.
 
The best time to harvest courgettes is in the morning, using sharp shears and a gentle hand.
 
Check your plants every day or two because courgettes grow incredibly fast.
 
And remember, the more you harvest courgettes, the more the plant will reward you with fresh fruit.
 
Happy gardening.
