There’s nothing worse than biting into an apple and finding a worm inside. It may look rosy and fragrant on the outside, but inside it’s a mushy mess. There’s little joy in eating fruit that’s been compromised. And the tree supplies all its apples with the same nutrients, so worm-infested fruit gets just as much as healthy fruit…
But is there a way to tell if a worm has made its home in an apple while it’s still green?
You won’t find out just by feeling the apple with your fingers. If you use a microphone and an amplifier, even the biggest apple won’t be able to hide its secret. Simply bring the microphone close to the fruit while it’s still on the branch, and the microphone will pick up the faint rustling of a caterpillar that has burrowed inside. The amplifier turns that subtle sound, which is inaudible to the human ear, into noise—if you want, a deafening roar!
Once you identify a damaged apple, pick it. That way, only healthy fruit remains on the trees. Those apples will grow and fill with juice more quickly, receiving more nutrients.
But even a perfectly healthy apple can fall victim to birds. Radio technology can help here. Hang speakers around the garden and periodically play a recorded bird alarm call. The feathered pests quickly flee from the perceived danger, leaving the fruit intact.
