It is easy to grow bottle gourd by seed sowing method throughout the year. Summer is the best time to plant seeds. Seeds are sown directly in small pits or on raised beds which germinate in 14-20 days. Bottle gourd seedlings are very fast growing and quickly form the habit of a climber. A strong trellis support should be built for the climber to grow. Many gardeners let the plant trail on the ground or allow it to climb on poles or roof of the house. Pinch off growing points of the young plant to induce branching. The side shoots will develop separate male and female flowers in the second month. After pollination, the female flowers have little gourds beneath them. If male flowers are plentiful, some of them can be removed.
