I just picked my first watermelon. Here is 3/4 of it. Shared the other 1/4 th with a friend. It was good, sweet and juicy. I have 20 more at least out in the garden and more coming on. They are about $5.00 + at the store. I did a little research to find out how to tell if they are ripe. People say thump them but my daughter picked one a week or so ago after thumping it and it wasn't ripe. What I read on the internet was if the skin turns dull, the little curly things by the stem turn brown and the skin resists your thumbnail pressure, these are all signs of them ripening. Also if they turn yellow where they sit on the ground. This one split open so I knew it was ready. Got right on it. From now on I'll have to keep a close eye on them.
