I knew this was not ripe, but wanted to see if it was seeded. I found a youtube video spring of 2023 that showed me how to know a watermelon is ripe on the vine. Next to the vine that goes into the watermelon there is a curly little thing, almost like a pigs tail. When it is brown and dry the watermelon is ready. It did not fail me once last year. I will try and take pictures as they mature to show later. Does no good for picking one in the store, but sure works if you grow them!
