As the name implies summer squashes love the summer weather. In fall make sure to prepare the site for summer squashes. Place compost and leaves in the worked soil. In spring make sure the soil is warm for transplanting. You can keep the soil warm by covering it with plastic throughout the fall weather. Squash does not transplant well hence you should try the direct seeding method. Make sure the temperature is warm and in the range of 70 F – 75 F. Sow the seeds about 18 inches apart.
