Starting to think a (what I assume is a volunteer) watermelon vine is going to be the biggest one I've ever had. I know it's boring to have to wait until later to see a pic, but I'm @ work & figured I'd start yakking about it while I had a minute & was thinking about it. Yesterday I was noticing a couple of the leaves are around 2 ft across. It could be something else, in a spot where I put kitchen scraps to compost. Y'all can tell me later.
I have much better luck with the volunteer mutts than trying to grow bought or saved seeds. Tell me about your big watermelon leaves! Pics? Please!
The basic watermelon entry here could use some more pics too to augment the excellent closeups already there. I guess most people end up with shaggy grass & other rogue plants around watermelon vines, so that's probably why there aren't any mature vine pics... or most people know their watermelons' names?:
