Hi, I have got one Zucchini plant where I am getting lots of male flower but not female flowers. I had some female flowers before and had couple of fruits from this plant. But now its producing only male flowers. Also too many leaves have come up in the plant and noe of the leaves are growing bigger, all the leaves are cramped in a short area. Do anyone know the reason for this? do i need to cut the leaves a little bit to allow growth for leaves? I have one more plant and thats doing well, regularly giving fruit.
