Earthworms in my young Juniper Bonsai?

Question

I discovered two earthworms (there may be more) in a juniper bonsai that I recently purchased. I know earthworms are good for plants in gardens, but are they good or bad for Juniper bonsai?

I know Junipers can easily suffer from "root rot", do earthworms help this or make it worse?

(The soil for my juniper drains very well and is composed of soil, bark pieces, brick pieces, and sand; and I water it about twice a week because I let it get a little dry between waterings, but not completely dried out. The plant is outside and receives indirect sunlight on a covered patio.)

Does the presence of earthworms mean my soil is too damp for a juniper?

Another edit:
If eartheworms are good for bonsai trees, why is it that most of the search results for "earthworms in bonsai" on the net explains formulas for liquids that kill earthworms?

P.S. I am hoping that the earthworms are either good or cause neither direct nor INDIRECT harm to my bonsai. I've heard that the tunnels they dig help drainage, but the poop they create clogs drainage. Also, if they die, bacteria grows like crazy around their carcus. :-(

Answer 1

Earthworms will help avoid rot and fertalize the tree. Earthworms signal a healthy soil. They are your bonsai's friend, not foe.

Answer 2

Worms are great for the soil and for your tree. Leave them alone. You're doing just fine.
