Growing courgettes can be a rewarding experience, providing a bountiful harvest throughout the summer months. However, like any gardening endeavour, it comes with its challenges, especially here in the Midlands where the weather can be unpredictable.
Quick Answer
Common courgette issues include powdery mildew, blossom end rot, and poor fruiting. Address these by ensuring proper watering, spacing, and pest control.
Common Courgette Growing Problems
Powdery Mildew
One of the most common issues I see is powdery mildew, especially during humid spells. It appears as a white, powdery substance on the leaves, which can stunt growth.
- Ensure good air circulation by spacing plants at least 90 cm apart.
- Water the base of the plants to keep foliage dry.
- Remove infected leaves immediately to prevent spread.
Blossom End Rot
Blossom end rot is another frequent problem, caused by a calcium deficiency often linked to irregular watering.
- Maintain consistent soil moisture by watering deeply once a week.
- Mulch around plants to retain soil moisture.
- Test soil pH and adjust with lime if necessary.
Poor Fruiting
If your courgettes aren't fruiting well, it might be due to poor pollination or nutrient deficiencies.
- Encourage pollinators by planting flowers nearby.
- Hand-pollinate using a small brush if necessary.
- Feed plants every two weeks with a balanced fertiliser.

Preventative Measures for Healthy Courgettes
It's always better to prevent problems before they start. Here are some of my tried-and-true tips:
- Choose resistant varieties that suit the Midlands climate.
- Rotate crops annually to minimise soil-borne diseases.
- Keep the garden tidy and remove debris that can harbour pests.
Frequently Asked Questions

Yellowing leaves can indicate nutrient deficiencies, overwatering, or pest problems. Ensure balanced fertilisation and check soil drainage.
How often should I water my courgettes?
Water deeply once a week, more often during dry spells, making sure not to wet the leaves to prevent disease.

Yes, courgettes can thrive in containers with at least 18 inches of depth. Ensure proper drainage and regular feeding.
