You cut open a watermelon and saw cracks? Stop eating it immediately! Here’s what it means!….see more.>
What causes it? Hollow heart happens when the watermelon grows too fast and the inside flesh can’t keep up. The main triggers: 1. Irregular watering: Heavy rain or overwatering after a dry period makes the fruit swell quickly. 2. Pollination issues: If bees don’t pollinate every part of the flower evenly, some sections of the fruit develop faster than others, leaving gaps. 3. Temperature swings: Hot days + cool nights during growth stress the plant. 4. Variety: Some seedless and large varieties are more prone to it than small, round ones. Think of it like bread rising too fast — cracks form because the structure expands unevenly. Is it safe to eat? Yes, 100%. Hollow heart doesn’t mean mold, rot, or pesticides. The white arrow in your image points to a natural split in the flesh. Taste and sweetness are usually normal, though texture might be a bit mealy around the cracks. If there’s no sour smell, mushy brown spots, or mold, just cut around the cracks and enjoy. How to pick a watermelon less likely to have it: 1. Look for symmetry: Even shape = more even pollination. 2. Check the field spot: A creamy yellow spot means it ripened on the ground, not picked too early. 3. Thump test: A deep, hollow sound usually means ripe. A dull thud can mean overripe + more cracking. 4. Weight: It should feel heavy for its size — that’s water content, not cracks. Fun fact: Farmers actually call it “heart” because the cracks often form a heart or star shape in the center. Some people even look for it as proof the melon is extra juicy. So that “cracked heart” watermelon is just a melon that grew with enthusiasm. Still sweet, still hydrating, still perfect for summer.
