How to pick a ripe watermelon:

There are a few ways to tell if a watermelon is ripe:

  • If you hold it against your belly and give it a pat, you should feel a good thump against your belly.
  • The webbing should be larger. Smaller and tighter webbing means it was picked too soon and will not be as sweet.
  • The underside spot where the watermelon sat on the ground should be large and yellow or gold, not small or white.
  • It should smell slightly sweet.
  • It should feel heavy for its size.
  • Rounder is better than elongated.

Green stems mean the watermelon isn't ripe while a dry stem means it is right. Smaller webbing means the watermelon is bland while larger webbing means it is sweet.
