Gourds should be cut from the vine with a few inches of the stem attached. Take care not to bruise the gourds during harvest, as this increases the likelihood of decay during the curing process. Discard any fruit that is rotten, bruised or immature. After harvesting, gourds should be cleaned with soap and water, dried, and rubbing alcohol applied to the surface. Curing cucurbita gourds is a two-step process which may take 1 to 6 months depending on the type and size of the gourd.
Surface drying is the first step in the curing process, and takes approximately one week.
During this time, the skin hardens and the exterior color of the gourd is set. Place clean, dry fruit in a dark, well-ventilated area. Arrange gourds in a single layer and make certain that the fruits do not touch each other. A slatted tray will allow air circulation around the gourds. Check gourds daily and discard fruit that show signs of decay or mold and any that develop soft spots.
