The vines on my Turk's Turban gourd are turning yellow, as are the gourds. It doesn't look good and I don't know what the problem is. I hope someone can help. The vines on my Dill's Atlantic Giant pumkin are also turning a yellow color. We have been getting a lot of rain lately and I thougt that might be the problem. But I am not really sure. It is my first year really growing pumpkins and gourds and any advice would be great. Thanks!!!!!!!!
