Courgettes or Zucchini, like marrows, squashes and pumpkins all belong to the gourd family.
Sow three seeds at about 2.5 cms apart and the same deep. When the first true leaves have appeared, thin out to leave the strongest seedling. Make sure to water well and protect against slugs.
Continual cropping is essential to prolong fruiting. Cut the stalk of the fruit you want to harvest.
