Winter squash includes acorn squash, spaghetti squash, butternut squash, delicata squash, hubbard squash, kabocha squash, turban squash, sweet dumpling squash, and of course all types of pumpkins. Prepared winter squash also freezes well and keeps for about 6-8 months in the freezer.
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.
