Hi Haffy, Welcome to All Things Plants!
I used to grow the
Fiddle Leaf Fig (Ficus lyrata) but my plants stayed outside year-round so I can't offer advice on what may be happening with your indoor tree losing it's leaves; it may just be the time of year combined with lower light and lower humidity.. Here in Florida, many folks grow it as a landscape plant. The Fiddle Leaf Ficus (like others in the Ficus genus) prefers high humidity so perhaps your plant is needing additional humidity from the dry heat of winter? You can try sitting the pot on a tray of moist pebbles to raise the humidity around the plant; just remember to refresh the water in the tray as it evaporates.
@Drdawg Ken grows and sells the Fiddle Leaf Ficus so he can probably offer suggestions on what might be happening with your plant but he was having some back surgery so he might be off site for a few days. Hopefully others who grow this beauty as an indoor house plant will pop in with some tips for you until Ken can respond.
Again,
Lin
