When should I harvest my summer squash?
Harvest zucchini and other long-fruited summer squash varieties when the fruit are 1½ to 2 inches in diameter and 6 to 8 inches long. Scalloped types are best when 3 to 5 inches in diameter. Fruit should have soft skins (rinds) that are easy to puncture with a fingernail. Seeds should be soft and edible. Harvest plants frequently for continuous production.
