Fertilizer for Acid Loving Plants

Thousand Oaks, CA(Zone 10a)

I mistakenly bought fertilizer for acid loving plants. Will it harm the non acid loving plants I have. I wanted to fertilize my potted hibiscus, trumpet vine, and others.

I doubt it--even if the fertilizer does have a small amount of something in there to help reduce soil pH, I doubt there's enough of it to change your soil pH much. Also, I can't speak for the rest of your plants, but hibiscus like soil that's slightly on the acidic side. However, at least if they're tropical hibiscus, they won't bloom as well if you give them too much phosphorus so I'd check the middle number on your fertilizer before you use it on them.
