Hello, My pumpkin leaves are starting to get a dry crispy edge to them all of a sudden. I am not sure if it is the 90 degree weather we are having here in Pa. all of a sudden. It looks like they might be catching a fungas of sorts. It looks like water dried on the leaves and burned them. I have only beeen watering after dark. Does anyone have anyhelp? Also what are the benifits of using 2 plants to pollinate with. One male of a different seed to a another female? Have a nice day Dave Light
