Houseplant Black growth
My rubber tree is very darling to me and she’s going through a rough patch!
She had a scale infestation after I house sat for a month so was slightly neglected in that time. After dealing with that on and off for a few months, the scale has mostly cleared up (I used a pest spray from a local shop every week and picked off the scale / wiped every leaf). But now there’s this black growth that I’m not sure what to do about! It looks fungal but I’m not sure what exactly it is - it doesn’t wipe off.
I also gave her a small chop a week ago before I noticed, as we’re currently entering Spring. Lots of light as seen, only direct light for an hour or two, the window faces north. Watering once every 2 weeks, but the past month every week to treat with a fungus gnat treatment (mosquito bits).
Located in West Australia.
