Ever bitten into a juicy peach and noticed some white stuff on the pit? You’re not alone, and there’s no reason to be alarmed.

I was curious about it too, so let’s dive into what it means. Peach callus tissue is a group of cells that haven’t fully formed yet. Think of them as young cells still deciding what they’ll become, like kids exploring different hobbies before picking one.
