Sowing Instructions

 

Indoors: Sow seeds in small pots or trays filled with fine, fertile compost from March to May. Cover lightly, maintain soil moisture, and keep at 18–22°C. Transplant seedlings after the last frost into a sunny, sheltered position.

 

Outdoors: Direct sow or transplant into well-prepared, fertile soil from April to June. Space plants 60–70 cm apart to allow for healthy growth and airflow. Regular watering and feeding promote strong, continuous fruiting.

 

Harvesting: Pick courgettes when young and tender (10–20 cm) for the best flavour and texture. Frequent harvesting encourages the plant to produce more fruits.

 

Courgette Defender F1 RHS is perfect for gardeners seeking a reliable, high-yielding courgette with excellent disease resistance. Its compact growth, tender fruits, and RHS recognition make it an outstanding choice for both beginner and experienced gardeners.
