Ajuda com minha ficcus, folhas estão caindo
Why the leaves is falling down?
The room is illuminated for 10 hours a day.
It is 1.5 meters from the window.
I water the plant once a month, as it is in the living room of my apartment and I don't have a balcony.
It does receive sunlight for 3 hours in the morning.
The leaves have started to fall off, but it had been 20 days since the last time I watered it.
There are no mealybugs or mites.
The pot has a drainage hole and is filled with potting soil, charred rice husks, worm humus, and charcoal.
