Terri, when I found the mold, I emailed them and got a response telling me that they had just started repotting that particular plant and appreciated my letting them know. In the weeks following that, I learned that almost everybody who order, all differnet plants, had mold problems, so it wasn't just the one type I ordered.
As long as they are repotted into fresh mix they'll be alright. Mine are doing fine
I wouldn't bother...they are well aware of the problem.
