I was given this guy, a mitre aloe and a cobweb leek all in the same pot. This week, I noticed that the aloe was growing through one of the leaves on the Mexican rose. Because of that, *everyone* got sent to separate rooms --erm, pots-- but this guy still looks distinctly unhappy. Dr Plant diagnosed a fungal infection, so I applied some neem oil. (His new pot and soil are also more draining than what he was given to me in.) His injured leaf looks like it's healing. Anything else I should do for him in the meantime?
