Mulching is highly encouraged for several reasons. It helps to conserve moisture, plus it will help to keep weeds out and the fruits cleaner. Gourds, like all other members of the cucurbit family, produce separate male and female blossoms, which must be pollinated by insects. They also suffer from the same pest problems as squash and cucumbers the squash vine borer, squash bugs, cucumber beetles and powdery mildew. Monitor for these pest problems, to control them early.
Most gourds require a long growing period.
Usually a minimum of 90 days up to 180 days is required from seed to harvest. At maturity, the fruits will develop hard, glossy, shells. Some will be smooth, others warty. Some will be brightly colored, others white, tan or light green. They are ready to be harvested when the stems dry and turn brown.
