Hey guys and gals new to the forum and bonsai so please be gentile. I recently got a na na juniper and re-potted it I came home today and found an earthworm on top of its soil should I be concerned? I removed it and put in on the ground also my bonsai (the juniper on my avitar) is on top of a wooden table outside my patio so I have no idea how it even got there thanks in advance for any input

Nope. Soil has life in it in all sorts of forms.
I am always happy with earthworms as they help decompose whatever organic stuff is in there.
