1 to 1 1/2 inches
Plant Spacing

3 to 5 feet

Days to Harvest
50 to 55 days
Directions

Sow the seeds directly outside at least a week after your last spring frost. The soil needs to be warm (at least 65 degrees F). If you have a short growing season, start your seeds indoors. Sow (plant) the seeds 3 to 4 weeks before you plan to transplant your seedlings outside (2 to 4 weeks after your last spring frost).

Don’t be in a rush to plant in the spring. Transplants or “starts” take about 40-55 days (depending on the variety) to mature. Therefore, waiting can help to avoid problems from pests and diseases that are common earlier in the season. But don’t wait too long! Transplant your seedlings outside before the second set of “true leaves” grows. Choose a spot that will get full sun. To avoid powdery mildew, water the base of the plant. Do not water the leaves. Harvest summer squash when they are young and tender before the rinds begin to harden. Use a knife to cut fruits from the plants.
