There won't be root rot. It's just growing in a pot with ferts and soil, but what you do is put adequate fert in the pot and never add anything else later. This is the problem people keep running into. I know this cuz I used to be one of those people. Then somebody told me to just put this fert in the container and leave the plant alone, just give water when necessary, and it worked better than any other method of fertilizing. I kept feeding different ferts not really knowing what I was doing. I was just guessing. I was guessing wrong.
