Spike Hairbrush Direct sunlight 6+ hrs light SE 3.0" pot Drainage Plastic Regular Indoor Near A/C unit Near heater View @zarasplants's Oasis #Hairbrush Discussion #CactusClique Does anyone know what type of cactus this is? Not sure I have selected the right thing? I just received this totum pole cactus in the mail and it appears to have some sort of black rot at the top. I am so disappointed. Is there anything I can do to save it?
