FAQs
When is the best time to sow these seeds?
Sow seeds indoors in pots during the spring, ensuring they are not moved outside until the risk of frost has passed.
How much space does each plant need?
Each plant grows to about 90cm across, so provide at least 90cm of space between plants to allow for healthy airflow.
Are these seeds suitable for containers?
Yes, provided the container is large enough to support the root system and can accommodate the plant's 90cm spread.
Why is the 'F1' label important?
F1 hybrids are bred to combine the best traits of two parent plants, resulting in superior disease resistance and uniform, high-quality yields.
How often should I harvest?
Check the plants regularly from mid-June; harvesting courgettes when they are young and tender encourages the plant to produce more fruit.
Do I need to stake these plants?
Generally, no. Their compact habit is designed to grow low to the ground, but you can provide a small support if your garden is particularly windy.
Troubleshooting
Poor fruit production
Ensure the plant is receiving at least 6-8 hours of direct sunlight and supplement with a potash-rich fertilizer.
Yellowing leaves
This is often a sign of inconsistent watering or nutrient deficiency; check soil moisture and apply a general-purpose vegetable feed.
Fruits failing to develop (rotting at the end)
This is often due to irregular watering. Ensure soil moisture is consistent and avoid splashing water on the developing fruit.

Setup, Compatibility & Care
To begin, sow seeds indoors in individual 7.5cm pots during the spring. Ensure the indoor environment remains warm until the threat of frost has completely passed. When transplanting to the outdoors, choose a position that receives full sun and ensure the soil has been amended with compost or well-rotted manure. Maintain consistent soil moisture by watering at the base of the plant to keep the foliage dry, and apply a balanced liquid fertilizer periodically to support the plant's vigorous growth and heavy fruit set.
