I'm new to gardening, so you can imagine my delight when I noticed the female flower of my watermelon plant had been successfully pollinated 2 days ago. While admiring my tiny watermelon baby, I noticed a small bug on it. When I remove the bug, I accidentally scratching the surface of my watermelon baby with my fingernail. Later that day, I noticed the scratched area turned black. I've read that black spots turn into rotted areas of mature watermelons. Is this true? Is my watermelon ruined? Should I just remove this baby and wait (hope) for a new one to pop up in its place? Thank you!

You may have a watermelon in your future or you may not. We aren't good at predicting the future - don't remove it, just let nature do its thing.

Ash,
Sorry I'm of no help but
I think @farmerdill can tell you more if your damaged watermelon baby will make it.
We do have a Vegetables and Fruit forum with experienced and knowledgeable gardeners,

Thank you both for your responses!

That scar looks pretty bad, but not to worry healthy plants will keep setting melons. That particular melon will probably abort on its own. If it gets fist size and is misshapen, remove it.

Okay, I will wait and see what happens. Thank you!

Welcome to NGA, @PlantMomInTraining !

Not to worry, your plant should give you lots more babies even if that one was injured.

And, I hope you will join us on the vegetables and fruit forum!
