Will my pumpkins survive?
The plant cannot function without the leaves. If you have pumpkins on the vines, stop removing the leaves. Keep the plant watered at the base of the plant and they may survive. Powdery mildew is a common host of pumpkins. See our profile on powdery mildew. Pull up and remove all plant debris at the end of the season. Look for resistant varieties next year. http://vegetablemdonline.ppath.cornell.edu/Tables/TableList.htm
