Both winter and summer squash are warm season vegetables that get planted early in spring. The difference is that summer squash get harvested regularly through summer, and winter squash get harvested only once after summer.

Zucchini, crookneck, pattypan and other summer squash are very productive as long as the weather is warm, and their fruit gets harvested. Fruit that stays too long and continues to mature gets big and tough, and consumes resources that would otherwise be diverted to newly developing fruit. Therefore, regular harvesting of the more desirable juvenile fruit actually promotes production.

Pumpkin, acorn, butternut and other winter squash grow all summer, but each plant should be allowed to produce only a few fruits each. Some pumpkin vines produce only one fruit each. Once the desired number of fruits are developing, fruits that start to develop later should be culled to concentrate resources into the primary fruits. These fruits mature all summer to get harvested after frost.

So, by the time that summer squash stops producing, winter squash is about ready for harvest. Where autumn weather is cooler, the tender foliage shrivels after frost, exposing the richly colored but formerly obscured ripe fruit. Winter squash is supposedly best if slightly frosted prior to harvest, which might take a bit longer here. After harvest, they should be left to cure for two weeks or so.

Winter squash vines are more rampant and somewhat shabbier than those of summer squash. Those that produce smaller fruit might be able to climb trellises or onto firewood piles that are not in use through summer anyway. Female flowers tend to shrivel sooner than male flowers, but all flowers that are big and turgid enough to bother with are edible. Bloom continues through summer.

If properly stored, even without canning or freezing, intact winter squash can last for months, until summer squash start producing the following season.

  1. We get very nervous about frost damage to the squash and pumpkin when frost warnings are in effect. Curing up for a couple of weeks in a nice warm greenhouse does a lot to improve squash flavour. When squash fruits mature early, late August or early September, and the weather turns hot and sunny, we sometimes see some sunscald on the fruits, especially as the squashes lose foliage as often happens as powdery mildew shrivels the leaves on susceptible varieties.

    1. I notice that people are more careful with them in other climates. Our frost is not cold enough to damage squash. Sunscald can be a problem like it is there. Mildew does surprisingly well here, even with minimal humidity.
