This is my first veg garden and I am not sure what is killing off my squash. It started with what I thought was powdery mildew. Sprayed with milk and baking soda mixtures to no avail. I have had on zucchini squash this summer and a few cucumbers. What I see now is the stems are turning yellow and soft and eventually the plant breaks off at the base. I am wondering if it is some type of fuserium wilt or bacterial or fungal problem that should keep me from planting in this area. It is really the only spot for a vegetable garden I have. Thanks
