(Lagenaria siceraria unless stated otherwise) Whether true gourds, angled gourds or edible gourds, these squash relatives are all originally from the Old World, and all need similar conditions: a long season of hot weather and abundant moisture in a rich soil. Gourds may be direct sown into warm soil or started indoors a few weeks early. The fruits will be straighter and more symmetrical if the long vines are trained up a trellis, but all may be allowed to sprawl along the ground. Some may run 20 feet! The edible sorts are best harvested when young, tender, and mild tasting.
