How Long Do Zucchini Plants Harvest?

Zucchini grows from early summer to fall.

Zucchini (Cucurbita pepo) grows prolifically all summer long--yielding so much fruit that you may grow weary of it long before it putters out in the fall. One or two plants is sufficient for most families, and usually provides enough zucchini for fresh eating, freezing and sharing with the neighbors.

First Harvest

Zucchini plants grow quickly and produce fruits shortly after pollination. Depending on the variety, expect fruits within 35 to 55 days after planting, according to the University of Arizona Master Gardener's Journal. For best results, plant zucchini in full sun after all chance of frost is passed and soil is at least 70 degrees Fahrenheit.

Growing Season

Zucchinis keep on producing fruit right up until the first frost kills them. Pick them when they are between 6 and 8 inches long for the tenderest crops and to encourage more fruit production.

Considerations

One or two plants produce four or five fruits per week, depending on conditions and the variety. Even the most avid zucchini lover eventually may tire of zucchini. Slow production by leaving one or two fruits on the vine, according to University of Arizona Master Gardener's Journal.
