Growing your own pumpkins and squash can be very rewarding for home gardeners. Many people, however, are not sure when to harvest their squash to get the best flavor. Squash is harvested at different maturities depending on the type of squash.

Summer squash, such as crookneck or zucchini, are harvested and used while they are still immature and tender. If allowed to become too large, they may become seedy, and the quality and flavor will be affected. Also, if large fruit are allowed to remain on the vine, the plant will decline faster and will not produce as many fruit. To prevent the spread of plant diseases, only harvest the fruit when the leaves are dry. Cut the squash from the plant, being careful not to damage the vine.

Pumpkins and winter squash, such as acorn or Hubbard, are harvested when mature. A good way to tell if the pumpkin or squash is mature is to press against the skin with a thumbnail; the skin should be hard and not easily punctured. Another sign to look for is the development of a yellow spot where the pumpkin or squash rests on the ground. If the skin resists puncture by a thumbnail and has developed a yellow to orange spot, then it is ready to be harvested.

Winter squash and pumpkins will not be harmed by a light frost, even if it kills the vine. If a hard frost is expected, harvest the fruit by cutting them off with a piece of vine attached. Allow them to cure in a cool, dry place for a few days. Allowing them to cure will increase the length of time that you can store them. If a cool, dry place is not available for temporary storage, the fruit can be cut-up, steamed, and frozen until you are ready to use it.
