Bottle gourds are grown by direct sowing of seeds or transplanting 15- to 20-day-old seedlings. The plant prefers well-drained, moist, organic rich soil. It requires plenty of moisture in the growing season and a warm, sunny position, sheltered from the wind. It can be cultivated in small places such as in a pot, and allowed to spread on a trellis or roof. In rural areas, many houses with thatched roofs are covered with the gourd vines. Bottle gourds grow very rapidly and their stems can reach a length of 9 m in the summer, so they need a solid support along the stem if they are to climb a pole or trellis. If planted under a tall tree, the vine may grow up to the top of the tree. To obtain more fruit, farmers sometimes cut off the tip of the vine when it has grown to 6–8 feet in length. This forces the plant to produce side branches that will bear flowers and yield more fruit.
