Butternut Squash are a warm weather vegetable, thus planting occurs from early spring to mid-summer.
Butternut squash cultivation begins with a hill. Draw your garden soil into a hill about 18 inches high. This allows the soil to heat around the seeds and roots. Your soil should be well amended and well fertilized since butternut squash plants are heavy feeders. Plant five or six seeds per hill about 4 inches apart and 1 inch deep. Keep the soil moist, but not soggy. In about 10 days, the seeds will sprout. When they’re about 6 inches high, thin out the weakest leaving three plants per hill. The butternut squash growing season is about 110-120 days for fruit maturation
