I planted a watermelon plant around the middle of a summer in a pot. (Yes I know. I’m growing watermelon in a pot. I’m going to transplant it soon.) The flowers formed and a watermelon came. It’s about 1 1/2 inches in diameter. But here’s the thing: it’s been exactly that size for over a month! I’ve been waiting for a delicious homegrown watermelon, and the package says it should be a “12 lb round melon”. It’s not showing any signs of dying or anything, it just seems to be growing too slow, since it already passed its estimated harvest date. I had to move it inside for the winter because it’s growing so slow. Thanks in advance!
