Courgettes are tender plants, so they will not tolerate cold.
Courgettes are tender plants, so they will not tolerate cold. They are also fast-growing. Sow them around four weeks before your last frost date, and keep them somewhere warm until the risk of frost has passed. Give them a large growing space as they can make very large plants. This will help them be more productive too. Follow this simple guide for more information on how to grow courgettes.
