Oh No!

I headed out tonight with my watering can to water some plants. When I was watering the quarter flat of little plants that I haven't gotten around to planting yet...there they were...watermelon! I forgot to plant the watermelon! I'll have to find a nice edge piece for them so I can let them trail all over the flower beds...no more room in the garden for those big guys!

I've never planted them before. Anyone have any great watermelon growing tips to share with me?
