Q

My zucchini plant has white spots in the leaves of the plant. New leaves are green but mature with the white spots. There is no powder residue or other obvious sign of fungus. No other plant in the garden has this appearance. What is the problem?

Answer(s)

A

There may be nothing wrong with your zucchini.  Some varieties produce white splotched markings on the leaves.  Is the plant growing and producing well?  Are the leaves normal size and shape?  If so, you just have the variety that gets white markings on the leaves as they get older.  I have that variety, and the leaves start out all green, but as they get full size, they get white patterns on them.  If you have further questions, you can call us at 851-8462
