I'm using a mod that makes dead bits of plants turn red, but the mystic bamboo's health goes down when I trim off the red bits. Is that how Mystic Bamboo is supposed to look? Or do I need to upgrade my shears?

Uprgade your shears.

What level shears do you have?

I have l1 shears and I'm saving for l2.

that will happen to most plants with l1 shear

Its a bit of the shears and also the bamboo is redish on its own, could be cutting some live off? so maybe change that one to a different color, like florecent orange or somthing like that so you can be absolutely sure that your not just cutting off a bit of the acuall plant. the reds are somewhat the same. If you dont have the software to change the colors i know i do and would do that for you if you wanted, or theres others that im sure would be happy to help.

I have the red dead leaves mod, but bamboo dead and rare oak dead are regular.

Bingo! All I have to do is...oops...find the brown leaf mod and install it on bamboo and rare oak. I guess I'm gonna have to redownload the red once I find the bamboo brown and rare oak brown. I didn't save my original images...But it's REALLY hard to see the brown bits.

Sp if you need the originals I can PM them to you.
