Content: But what do you tell your friends and family when the watermelon bottom turns black? Sadly, your fruits have succumbed to watermelon blossom end rot, and although affected fruits aren’t treatable and probably aren’t palatable, you can save the rest of the crop with some fast modifications to the bed. Why is Watermelon Rotting on Bottom? 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. When fruits are growing rapidly, they need lots of calcium, but it doesn’t move through the plant very well, so if it’s not available in the soil, they will be deficient. 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. Blossom rot in watermelons is caused by a lack of calcium, but simply adding more calcium isn’t going to help the situation. More often than not, watermelon blossom end rot occurs when water levels are fluctuating during fruit initiation. A steady supply of water is required to move calcium to these young fruits, but too much isn’t good, either – good drainage is necessary for healthy roots.
