These vines need lots of space to have the many leaves needed to produce enough energy to grow these large fruit and generally require 90 to 120 days to grow. The gardener in this photo is fighting to keep her window wells from being covered by a pumpkin vine. Certain winter squash do come in bush or semi-bush varieties (acorn, butternut, delicata). Vine tips can be pinched to keep vines in bounds but will limit production and quality. It’s better to find a spot with room such as this streetside gardener (photo).
Winter squash differs from summer squash in that it is generally harvested and eaten in the mature fruit stage. Vegetable spaghetti (photo) is probably an exception often being harvested in a semi-mature stage (harvest when the skin turns from green to buff). Pick most winter squash when the skin has hardened into a tough rind not easily dented with light fingernail pressure. The seeds within should have matured unlike the young tender seeds in summer squash. When ripened to maturity, fruits of most varieties can be stored for use throughout the winter.
Winter squash are harvested in September or October, before heavy frosts. Carefully cut squash from the vines, leaving two inches of the often-woody stem attached if possible. Avoid cuts and bruises to the fruit when handling. Fruits that aren’t fully mature, are injured, have had their stems knocked off, or have been subjected to heavy frost won’t keep. Use as soon as possible or compost (watch for seedlings in the compost).
Squash are best stored dry at a temperature between 50 and 55°F. Don’t pile squash more than two fruits deep. Single layers that don’t touch prevent rots from spreading through fruit.
Don’t forget that squash and pumpkin seeds can be dried in a dehydrator or roasted for a healthy snack. When scooping out seeds to use the fruit, wash clinging fibers from the seed and dry or roast.
