They can grow almost anywhere and under almost any conditions. Unlike many vegetables, they don t need to be fertilized, not even naturally. Though this is fine and won t harm them at all, it probably won t do much good. Even if the weather is bad, the pumpkins will grow. If no other crop survives, pumpkins will.
Flooding is the only thing that one really needs to watch out for.
This can rot the vines and prevent the pumpkins from growing. This isn t necessary, but works well. It s easier to control where the vines go this way. They should be started indoors sometime in April, outdoors in mid-May. Once transplanted outside, they should be left alone, except for occasional watering if the season is a dry one.
