In honor of Halloween today, I am posting a link to a blog which describes the impacts of various types of climate conditions on pumpkin production. You can find it here from Earth Gauge. If conditions are cool and wet, mildew can reduce the yields or rot the pumpkins on the ground. If conditions are hot and dry, there may be too many flowers and too little water available and pumpkins may be small. And chilly weather in the spring can result in reduced pollination because bees won’t fly until it is at least 55 F.
