feeding houseplants with brewed tea

Question

What houseplants can improve from brewed tea, if I have a large container of old tea? I used to put it on my inside ferns, but I don’t have them anymore. However, I do have a lot of other plants inside. Any ideas?

I would say you could use old tea on any acid loving houseplant. Here is an article that will identify some of those acid loving houseplants:
