Are you able to grow them year round outside?
Especially Azteca ants have a reputation of being aggressive.
I appreciate Coryanthes but have never tried to grow them.
are ants safe for orchids ? now need to figure that out. lol.
They tend to make the media in orchid pots really acidic, which is good for Coryanthes and not so good for many other orchids. As long as you don't mind the ants in your Cory, they shouldn't be a problem. However, if (when) they move to another pot, you might have a problem.
