You grow courgettes by giving them rich soil, plenty of sunshine, and consistent moisture from the moment you plant them.
It really is that simple, yet so many growers end up with tiny fruit or massive plants that refuse to produce.
If you’ve ever asked yourself “how do you grow courgettes?” and felt overwhelmed by conflicting advice, this post is for you.
We’ll walk through everything from planting to harvesting so you can enjoy a steady supply of fresh courgettes all summer long.
Let’s dig in.
How Do You Grow Courgettes: The Basics
Growing courgettes is one of the most rewarding things you can do in a vegetable patch.
They’re prolific, fast-growing, and incredibly versatile in the kitchen.
But before you rush out and grab seeds, let’s cover the essentials every courgette grower needs to know.
1. Start With the Right Timing
Courgettes are warm-season crops, so you shouldn’t plant them until the soil has warmed up properly.
If you sow too early, the seeds will rot in cold, damp ground before they ever get a chance to sprout.
In most temperate climates, late spring to early summer is the sweet spot for sowing courgette seeds outdoors.
If you want a head start, you can begin them indoors in small pots a few weeks before the last frost date.
Just be gentle when transplanting because courgettes hate having their roots disturbed.
2. Choose a Sunny Spot
Courgettes absolutely thrive in full sun, so pick a spot that gets at least six to eight hours of direct light each day.
The more sun they get, the more flowers they’ll produce, and more flowers mean more courgettes.
A sheltered position is also helpful because strong winds can damage those big, leafy plants.
If you’re growing courgettes in containers, make sure they’re placed somewhere that catches plenty of rays.
3. Prepare Rich, Well-Draining Soil
Courgettes are heavy feeders, which means they need soil packed with nutrients to perform well.
Before planting, work plenty of compost or well-rotted manure into the ground.
This does two things: it feeds the plants and it improves drainage, which courgettes appreciate.
They don’t like sitting in waterlogged soil, so if your ground is heavy clay, consider building a raised bed or mound.
A soil pH between 6.0 and 7.5 is ideal for growing courgettes.
How to Plant and Care for Courgettes
Once your soil is ready and the weather is warm, it’s time to get those seeds or seedlings in the ground.
Here’s how to plant courgettes and keep them happy through the season.
1. Space Them Properly
Courgette plants get big, so give them room to spread out.
Space them about 90 centimeters apart if you’re growing them in the ground.
If you’re planting in rows, leave around 120 centimeters between each row.
Crowded courgettes compete for nutrients and light, and they’re more prone to powdery mildew when air can’t circulate.
2. Water Consistently
One of the biggest mistakes when growing courgettes is inconsistent watering.
These plants need regular moisture, especially once they start flowering and fruiting.
Aim to water deeply once or twice a week rather than giving them a light sprinkle every day.
Try to water at the base of the plant rather than over the leaves, as wet foliage encourages disease.
3. Feed Them Well
Remember, courgettes are hungry plants.
Once they start producing flowers, give them a liquid feed every couple of weeks.
A potassium-rich fertilizer will support strong fruit development.
If your plants look pale or stop producing, that’s usually a sign they need more nutrients.
4. Watch for Pests and Problems
Slugs love young courgette seedlings, so protect them early on.
Aphids and spider mites can also show up, particularly in dry conditions.
Powdery mildew is the most common issue, appearing as a white, dusty coating on the leaves.
Good airflow, consistent watering, and removing affected leaves early will help you stay on top of it.
Harvesting Courgettes
The best part of growing courgettes is, of course, eating them.
But timing matters if you want the best flavor and texture.
1. Pick Them Young and Tender
Courgettes taste best when they’re small, around 10 to 15 centimeters long.
At this size, the skin is tender and the seeds inside are soft.
If you let them grow into marrows, they’ll still be edible but the flavor and texture won’t be nearly as good.
2. Harvest Regularly
This is key: the more you pick, the more the plant produces.
Check your plants every day or two during peak season.
A courgette can double in size overnight, so stay on top of it.
If you leave fruit on the plant too long, it signals the plant to slow down production.
3. Cut, Don’t Pull
Use a sharp knife or pruners to cut the fruit from the vine.
Tugging at the courgette can damage the plant and reduce future yields.
Leave a short stem attached to the fruit to help it stay fresh longer.
So, How Do You Grow Courgettes?
You grow courgettes by giving them warmth, sunshine, rich soil, and consistent care from planting through harvest.
It’s not complicated, but it does require attention, especially when it comes to watering and picking.
Get those basics right and you’ll be rewarded with an abundance of fresh courgettes that keep coming all season.
Whether you’re growing courgettes for the first time or you’ve done it before, the key is to stay consistent.
Plant them in the right spot, feed them well, and harvest often.
That’s really all there is to it.
