Question

What are signs that a watermelon on the vine is ripe?

Answer 1

Here in Ky,and when I lived down in Georgia,we just give them a thump or pat them with your Fingers,if it has a hollow sound they are ripe,if there is a solid sound wait a couple more days and thump them again,in the very center of the Melon!

Answer 2

I've grow watermelon for about 7 years and the best way I found is to wait until the stem coming out of the watermelon begins to dry up.  Then if it falls right off, your watermelon should be ripe.

Answer 3

The thump test will tell you. Kinda learned but not really roket science. We did a quick jerk of the stem with our middle finger, and if it came off - run with it. if it didnt let it be.
