Zucchini leaves going yellow
My zucchini leaves and cucumber leaves are going yellow. I am not getting any zucchini at all, but I am getting lots of cukes. What would the problem be?
They may be in need of some fertilizer. If the yellowing is followed by wilting, however, then your plants may be suffering from the onset of bacterial wilt, which will kill the plants and there is nothing to do but pull them up.
