Whether you're limited on space or just fancy giving it a go on your patio, courgettes are versatile and relatively easy to grow in pots and grow bags. Let me guide you through the process.
Quick Answer
To grow courgettes in containers, choose a pot at least 45cm wide, use a rich compost, water regularly, and position in full sun. Harvest from June to September.
Choosing the Right Container
When it comes to containers, size does matter. Courgettes have a deep root system, so you'll need a pot that's at least 45cm in diameter and depth. Grow bags are also a fantastic option, providing adequate room for the roots to spread.
Ensure your containers have drainage holes to prevent waterlogging, which can lead to root rot.
Preparing the Soil
Courgettes thrive in nutrient-rich soil. Fill your container with quality compost mixed with well-rotted manure or a slow-release fertiliser. This will ensure your plants have the nutrients they need to grow healthily.
- Use a high-quality multi-purpose compost
- Mix in well-rotted manure or slow-release fertiliser
- Ensure good drainage to avoid waterlogging
Planting Courgettes
In the Midlands, the best time to start courgettes is late May to early June, once the risk of frost has passed. You can sow seeds directly into the container or transplant seedlings that you've started indoors earlier in the spring.
For direct sowing, place two seeds about 2.5cm deep in the soil. Once they germinate, thin to the strongest seedling.
Watering and Feeding
Courgettes are thirsty plants. Ensure you water them regularly, especially during dry spells. It's best to water at the base rather than overhead to prevent mildew on the leaves.
| Month | Watering Frequency | Feeding Schedule |
|---|---|---|
| May | Every 3-4 days | Start with balanced fertiliser |
| June - August | Daily in hot weather | Weekly liquid feed |
| September | Every 3-4 days | Every 2 weeks |
Positioning and Sunlight
Courgettes need plenty of sunlight to flourish. Place your pots or bags in a sunny spot where they can soak up at least 6-8 hours of sun daily. This is crucial for fruit development and overall plant health.
Harvesting
With the right care, you can start harvesting courgettes as early as June. Regular harvesting encourages the plant to produce more fruit. Pick them when they're about 10-15cm long for the best flavour.
Frequently Asked Questions
Can I grow courgettes indoors?

What pests should I watch out for?
Look for slugs, snails, and aphids. Regular checks and good garden hygiene can help keep these pests at bay.
How do I prevent mildew on my courgette leaves?
