OK~ I'm stunned that we have managed to actually grow several watermelon this year. Now, I really, really need to know the secret of when to pick these! I'm fairly good when it comes to growing and eating Iowa Sweetcorn, not sure about this Iowa watermelon thing. I'm reading on line.....Knock on it~ Ok, I'm knocking and they sound kind of hollow. And then I'm seeing roll it over and if it's yellow, it's ready. Oh yeah, but how does one roll it over without breaking the stems~ which is a no-no.....Any advice, any of you have~ This Mom will take it. After All, It's All In a Mom's Day, Right?
