Hi y'all!

I'm so excited! I've got my first little round watermelon on my vine!
What should I do now? I've heard that they rot when they lay on the
soil so I bought some pine needles and put them under them. How long
will it take for it to grow ripe enough to eat? How will I know when
it is ripe enough to pick? Thanks for any help you can give me.
