I have spots on my paw paws
My paw paw trees are growing well, but the fruit gets spots on them about halfway through their growth and ripening.
Unfortunately the Paw Paw fruit is susceptible to Black Spot disease.
You can spray with Cooper spray prior to the onset of cooler weather.
Keeping your tree healthy will help if fight off this fungus.
Use a well balanced fruit fertilizer in the spring and autumn will ensure that your tree gets the nutrients it needs.
