Old sourdough starter

I have a sourdough starter that hasn't been fed for weeks.  😔   Thinking of tossing it but where?   Would it be OK in the compost pile, or in a new lasagna garden, on an old ash pile, or dug in slightly below the surface of a dry shady bank (under a hemlock tree) where I am hoping the thyme will spread. Would the acidity/bacteria in it help or hinder growth of beneficial creatures?  

Unless you just don’t want to deal with it anymore, you should feed  and it will probably revive.  Make sure the new material predominates.

If you just want to get rid of all or part, maybe dilute it and pour it some spot where the smell won’t be a bother.
