Kadie!
What is that nest looking-thingy that is nestled in between the 3 branches, on your last photo. It looks like you have den orchids on it.
I only use potting soil and perlite for all
My container plants, some get more perlite than than others. Depending on how dry or fast draining mix I need. Then always store bought orchids bark for all my orchids. Anything that is instant gratification and less work is fine with me.
