Plant your pumpkin seeds after the danger of frost has passed and the soil is thoroughly warm. Or start your seeds indoors and transplant outside when the soil warms up above 55 degrees. Check on the seed packet the number of days recommended for the pumpkin to grow big. Pumpkins love fertile soil.
Most pumpkin varieties take between 85 - 125 days to mature. Most of the heirloom and larger varieties are on the longer end of the spectrum. The number of days to maturity will be listed on your seed packet that you purchased. If you would like to have pumpkins on October 1st, count backwards to decide when to plant.
