Pumpkins require a long growing season of 75 to 100 frost-free days according to The Old Farmers Almanac. Do not plant the seeds until there is no further danger of frost and the soil is warm. Otherwise, the seeds may rot or not germinate.

Plant Halloween pumpkins in late May in northern climates and early July in southern climates. Harvest pumpkins when they are deep orange and have a hard rind. This is usually in late September or early October.

Pumpkin vines require a minimum of 50 to 100 square feet of growing space. Plant four or five seeds per hill at a depth of 1 inch. Space the hills 5 to 6 feet apart in rows 10 to 15 feet apart.

Dry pumpkins in the sun for about 7 days to harden the skin. Leave long stems when removing them from the vines to slow down the rotting of the pumpkins, then store them in a dry place at around 55 degrees Fahrenheit.
