These are often a good crop in French gardens, such varieties as Telegraph and others being easily cultivated in the frames. The seeds are sown singly in smallpots in February or March in the same way as Melons (see p. 222), and the young plants are grown on in practically the same way as that crop during the season, with the exception, however, that several fruits are borne one after another on each plant. The plants also require more water and a more humid atmosphere, and are practically covered with glass throughout the summer months. Ventilation is regulated according to the weather, and a great point is made of thinning out the shoots and pinching them back when the young fruits begin to swell.
