Planting and Care
Squash germinate best in warm soil temperatures of 70 F to 105 F.
Begin sowing when the soil has warmed to at least 70 F and all danger of frost has passed. Plant 4 to 5 seeds per hill at a depth of 1 inch. Space hills 3 to 4 feet apart. Thin to 2 or 3 plants per hill.
When sowing in rows, plant seeds 1 inch deep, 4 inches apart in rows set 4 to 5 feet apart. Thin plants to 1 plant per every 1 to 2 feet.
Squash can be started indoors for an earlier harvest. Sow 3 to 4 seeds per pot and thin to 1 or 2 plants per container. Harden off before transplanting. Set plants out in the garden when the soil has adequately warmed and all danger of frost has passed. Space 1 to 2 feet apart.
Mulch the soil to suppress weeds and retain soil moisture.
Mounding some soil around the base of the plants will help discourage squash borers from laying eggs.

Varieties to Consider
Embassy - heavy fruiting zucchini type
Sundance - smooth, bright yellow, crookneck type
Goldbar - golden yellow straightneck type
Peter Pan - light green scallop type
For best flavor and quality of fruit, harvest squash while fruits are small and still have a glossy, full colored exterior.
Pick elongated varieties when they are 7-8 inches long and 2 inches in diameter.
Harvest scalloped varieties when they are 3-4 inches in diameter.
