A more reliable test for watermelon ripeness, and the one that most expert gardeners rely on is the “thump test.” You may have witnessed a stranger at the market tapping on watermelons with their fingertips or rapping against them with their knuckles as they attempted to choose a good, ripe one.
The secret is that thumping a ripe watermelon will produce a rather hollow sound that’s difficult to describe but once you get the feel for it choosing ripe watermelons will become more routine than a matter of luck. The hollow sound can even be felt with your fingertips, almost as if the fruit contained jello in its center.
This technique may require a little practice and some trial and error, but once you get the hang of it your watermelon harvesting will become easier and more rewarding. For practice, experiment with a bin full of watermelons at the grocer until you can easily distinguish the difference in sound made by a ripe melon.
i HOPE THAT HELPS.
