If you don’t have much space, courgettes can be grown in growbags too, with one or two per bag because they like their own space and they are thirsty plants.
From June to October, when the courgettes are 10-15cm long, they are ready for harvest. By regularly picking the plants when they are smaller, will guarantee you have a longer harvesting period.
Not only is the veg tasty, but the flowers are edible too. They are commonly eaten stuffed with cheese and herbs, then fried, or simply tossed in olive oil and stirred into risotto.
