(HELP) how to run each 3D Animation Object with a Button UI

Hi friends,

I creating a farming game. I created one Tree with Shake - Leaf Falling Animation and then add it to Prefab.
After that, I create A Character and a button that when i moving character near Tree. A shake button is appear, i hit button ( On Click funtion ) - a Play-string name with Shake name Animation is calling. Thats fine.
But when i use multi Tree Prefab on Scene Game. and Hit Button again. ALL Tree Prefab is playing Shake Animation. Now, I stucking how to fix it for each tree prefab will run animation with button.

Sry my english.

I never used the animator but what could be the problem is that animators might be static, meaning that whenever you start an animation somewhere, the same animation starts everywhere. Not sure if that is the case but you could check that.
