Pumpkins are winter squash
and need heat to mature properly. Plant seeds in warm (70)
well-drained soil or start indoors one month before last frost.The soil should be well composted and mulched to hold moisture. Give lots of room.Feed midseason with compost or fish meal.Giant pumpkins for competitions are special varieties that are not particularly good to eat, but any pumpkin will get larger than normal if you: start it early indoors; transplant into very rich soil full of compost; give it extra nitrogen all through the season; and thin the fruits to one single pumpkin (the first) that gets all of the vines energy.
