Winter squash grow through summer. This includes spaghetti squash, Cucurbita pepo subspecies pepo. They thrive with warmth, rich soil and steady watering, to mature in late summer or autumn. They store nicely through winter. Technically, spaghetti squash can ripen earlier in summer. However, flavor improves with a bit of age. Mature fruits can stay on their vines until the foliage gets crispy at the end of the season.
Spaghetti squash fruits resemble melons. Most types get about four inches wide and eight inches long. Color ranges through creamy white, pale tan, yellow and golden orange. Fruits with pale color tend to have milder flavor. After cooking, the otherwise solid flesh pulls apart into squiggly bits that resemble spaghetti. The big seeds within may not be true to type. Related squash hybridize freely, particularly with zucchini.
The long vines of spaghetti squash can be somewhat sloppy. This can actually be an advantage. Such vines can sneak about into otherwise unused areas, like pumpkin vines. Alternatively, they might like to climb trellises or shrubbery. They are happy to grow from mounds too, and wrap around the perimeters. Fruits on the ground benefit from occasional turning. Superfluous and fruitless male flowers are good for frying.
