Welcome to the ultimate guide on how to grow delicious and nutritious courgettes right in your own backyard in the UK! Whether you’re a seasoned gardener or a beginner, this step-by-step guide will provide you with all the information you need to successfully grow courgettes and enjoy a bountiful harvest.

Why Should I Grow Courgettes?

Courgettes, also known as zucchini, are a versatile and nutritious vegetable that can be enjoyed in a variety of dishes. They are low in calories, high in fiber, and packed with vitamins and minerals. By growing your own courgettes, you have control over the quality and freshness of the produce, ensuring that you and your family are eating healthy, homegrown food.

Where is the Ideal Location to Grow Courgettes?

Courgettes thrive in a sunny and sheltered spot in your garden. They require at least 6-8 hours of direct sunlight per day to grow and produce abundant fruits. If you don’t have a suitable outdoor space, you can also grow courgettes in a greenhouse or on a sunny windowsill.

Soil Type and Preparing the Soil

Courgettes prefer well-draining soil that is rich in organic matter. Before planting, prepare the soil by removing any weeds and incorporating compost or well-rotted manure. This will provide the courgette plants with the nutrients they need to grow and thrive.

Watering Tips and Hints

Consistent and adequate watering is crucial for the success of your courgette plants. Water the plants deeply once or twice a week, ensuring that the soil is evenly moist but not waterlogged. Mulching around the plants can help retain moisture and suppress weeds.

Sowing and Planting Courgette

You can start courgettes from seeds indoors or directly sow them in the garden once the soil has warmed up. If starting indoors, sow the seeds in small pots or trays filled with seed compost. Keep the soil moist and warm until the seedlings emerge.

How to Grow Courgette from Seed

When the seedlings have developed their first true leaves, they are ready to be transplanted into larger pots. Harden off the seedlings by gradually exposing them to outdoor conditions before planting them in the garden.

How to Plant Out Courgette

Choose a spacing of around 90cm (36 inches) between each courgette plant. Dig a hole slightly larger than the root ball of the seedling and gently place it in the hole. Backfill with soil, firming it gently around the plant. Water thoroughly after planting.

General Care for Courgette

Keep the courgette plants well-watered and regularly check for any signs of pests or diseases. Remove any weeds that compete for nutrients and space. Courgettes are heavy feeders, so apply a balanced organic fertilizer every few weeks to promote healthy growth.

How to Harvest Courgette

Courgettes are typically ready for harvest when they are around 15-20cm (6-8 inches) long. Use a sharp knife or secateurs to cut the courgette from the plant, leaving a short stem attached. Regular harvesting encourages the plant to produce more fruits.

How to Store Courgette

Courgettes are best enjoyed fresh, but if you have an abundant harvest, you can store them in the refrigerator for up to a week. Place them in a perforated plastic bag to maintain freshness. Avoid washing the courgettes until you are ready to use them.

Problems with Growing Courgettes: Common Pests and Diseases

While courgettes are relatively easy to grow, they can be susceptible to pests such as aphids, slugs, and snails. Regularly inspect your plants for any signs of infestation and take appropriate measures to control them. Common diseases include powdery mildew and blossom end rot.

Where to Buy Courgette

You can purchase courgette seeds or young plants from local garden centers, nurseries, or online seed suppliers. Choose reputable sources to ensure the quality and authenticity of the seeds or plants.

What are the Best Courgette Varieties to Grow and Why?

There are several popular courgette varieties that are well-suited for growing in the UK. Some recommended varieties include ‘Black Beauty,’ ‘Tondo di Nizza,’ and ‘Defender.’ Consider factors such as taste, yield, and disease resistance when selecting the best variety for your garden.

What Tools Will I Need to Grow Courgette?

For successful courgette cultivation, you will need a few essential tools, including a spade or garden fork for soil preparation, a watering can or hose for irrigation, a trowel for planting, and a pair of secateurs for harvesting. Additionally, having a garden rake and hoe can be handy for maintaining the garden.


Growing courgettes at home in the UK is a rewarding and enjoyable experience. With the right location, soil preparation, and care, you can enjoy a bountiful harvest of this versatile vegetable.
