What is your experience with salt and red wigglers ?
I have some roasted, salted seaweed snacks that might be good worm food but for the salt. It can go in the outdoor compost if salt is bad for worms.
Too much salt will kill them. Since I don't know how much is too much, I never put ANY in the bin. Others have put in very small amounts with no problems.
I do not experiment with salt either.
