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 theyâre 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, so if your season is short, itâs best to start your seeds indoors to give them a head start.
