Our Garden Planner can produce a personalized calendar of when to sow, plant and harvest for your area.

Notes

Keep plantings small, to fewer than a dozen plants. Other types of summer squash help pollinate one another because they are of the same species.

Harvesting

Harvest zucchini when they are young and tender, about 6 inches long, before the rinds begin to harden. Use a knife to cut fruits from the plants.

Troubleshooting

Squash bugs and squash vine borers can be serious pests. Exclude them from young plantings with row covers.
