Looks very nice! My 9-year-old has just planted watermelon seeds in the backyard to raise money to buy a horse. He's really getting into planning all aspects of this business. I showed him this picture for inspiration.

May want to get it off the concrete as it gets heavier, don't want to prematurely bruise one side

I see another one looking to get going !

Lucky you! Hundreds of male flowers on mine, I got one marble sized watermelon then something ate it! Now I just have vines vines everywhere with flowers no fruit.
