How do you treat charcoal rot?

What causes black rot on watermelons?
Watermelon blossom end rot isn't caused by a pathogen; it's the result of fruit that lacks the correct amount of calcium to develop properly. ... A lack of calcium ultimately causes rapidly developing cells in fruits to collapse on themselves, turning the blossom end of the watermelon into a black, leathery lesion.
How do you keep watermelon from rotting?
Keep ripening watermelon from direct contact with soil to prevent rot and protect fruit from pests and rodents. When fruit is about the size of a softball, place it on a bed of straw or cardboard. Setting fruit on a light-reflecting surface, such as aluminum foil, will concentrate heat and speed up ripening.
Which fungicide can be used to treat black rot?
