Zucchini leaves are curled up because they have been attacked by a fungus. It starts at the bottom of the plant and slowly works its way to the top, eventually growing into fruit that is deformed or unusable for culinary use.
If your zucchini leaves curl up, it is possible that you have a virus called squash leaf curl. The virus causes the leaves to become curled up and die quickly. To treat this virus, use a fungicide spray or an organic pesticide to get rid of the virus.
Zucchini plants may be harmed by a lack of nutrients. Curled, puckered, or cupped leaves with a yellow tint are symptoms of potassium shortage.
