CUCURBITA pepo 'Yellow Crookneck'
Summer Squash, Yellow Crookneck Summer Squash
Cultivated for centuries by native populations of North America, summer squash ‘Yellow Crookneck’ remains a popular favorite in the United States. The bumpy, bottle-shaped fruits of this classic heirloom are bent at the neck, and have glossy, golden-yellow skin surrounding firm, delicious, buttery flesh. They are best picked and eaten when very young and tender, and are ready for harvest approximately 65 days from sowing.
Like many summer squash, ‘Yellow Crookneck’ is a member of the New World species Cucurbita pepo. These warm season, annual vines are monoecious, meaning single plants bear separate male and female flowers. The large, yellow, funnel shaped male blossoms are generally produced first, followed by the fruit-producing female flowers, which are distinguished by bulbous ovaries at the bases. Following pollination by bees, these develop into fruits, which are often obscured by the plant’s large, coarse, heart-shaped or deeply lobed foliage.
Plant squash seeds in full sun and deep, rich, well-drained loam when the soil has warmed and all danger of frost has passed. Regular water is essential, but the plants will not tolerate soggy conditions or wet feet. Where drainage is not optimal, it is advisable to plant them in raised mounds of fertile, porous soil. Vining types can be trellised if space is limited. Watch closely for squash bugs, cucumber beetles and vine borers at the base of the stems. Older plants are often susceptible to powdery mildew. Yearly crop rotation and removal of dead plant debris at the end of the growing season can help to minimize insect and disease problems.
