On the vine, these gourds can reach anywhere from 6 inches to 2 1/2 feet long, and about 4 to 7 inches in diameter. They ripen to dark green in late summer, and should be left on the vine until the skin begins to shrivel. When this occurs, harvest them and scrub the skin away, revealing the porous, dense network of tan-colored matter within. They will be full of seeds; just cut the gourd to desired size and shake out the seeds. They're ready to use! Sow seeds directly in full sun after the soil has warmed. Train the vine onto a trellis or fence to save space and to produce more rounded fruit.
