In order to grow pumpkins, there are a number of factors that need to be considered and some other things you should be sure to account for.
Plant four or five seeds per hill for semi-bushy varieties. Plant one or two seeds per hill for bushy varieties.
Pinch off vine ends when pumpkins start to develop. This will help focus the energy on pumpkins only instead of pumpkins and vines.
Pumpkin leaves may appear wilted in hot day sunlight. This does not necessarily mean that they need water. They will revive in the evening.
Ensure that the soil temperature is 70℉ then make your soil in a hilly manner with approximately 10 inches of spacing.
