Fiddle leaf figs trees can thrive indoors and outdoors.
This fiddle leaf fig is about 2 years old sits in an East-facing window. I use terra cotta pots for most of my plants as they let the dirt dry out. This fiddle leaf fig plant gets watered once a week and is fertilize at various times throughout the year.
