Has anyone ever used Rose food on orchids

Happy dance! I remembered my other question!

I found a bottle of granulated Bayer 3 in 1 Rose Food in the garage. I used to use it on my roses. Now, I can't use it because it's toxic to pollinators. But, I also have very pitiful roses because I can't use the Bayer.

Is there a reason I couldn't use it on the orchids? No pollinators in my sunroom. Has anyone tried it? It has a fungicide built in.
