Big Max
These squash are best planted between two and four weeks after the average last frost, and they  become ripe 110 to 120 days after being planted. The plants need lots of room to grow well, and to get them very big, only one fruit should be grown on one vine. They are harvested before the first light frost, when the plant's leaves die. Although recommendations are different, seeds are often planted at  deep, spaced  apart.
