What Causes Watermelon End Rot? Your garden is a little private paradise, a place for you to escape from the scary, loud world. Flowers are beautiful additions to any landscape, but there's something incredibly rewarding about growing your own produce. As relaxing and gratifying as it can be at times, gardening can also be a huge strain, especially when blossom end rot takes over your watermelons (Citrullus lanatus). Tip
Blossom end rot in watermelons is caused by a lack of water and access to calcium when the plant is fruiting. Treat this by ensuring the plant always has adequate water and adjusting the soil pH to optimize watermelon growth. Blossom End Rot on Watermelon
Blossom end rot is a common problem of watermelons, caused by a severe lack of available calcium during fruiting, notes the University of Arkansas Cooperative Extension Service. Because calcium is relatively immobile once taken up by a plant, it's difficult for a watermelon vine to redistribute this nutrient to newly developing fruits. Even if calcium was readily available at the beginning of the season, water stress can force the majority of calcium circulating in plant tissues into the leaves due to rapid transpiration.
