How many years can a Ficus Tree live.

Be sure it is getting the humidity and drainage it needs. It may need repotted? You might try misting it if you run an air conditioner (they take out humidity).

Good luck!

Even though it is a house plant it will drop some leaves in the fall.

Yes, try re-potting into a slightly larger pot with fresh soil added. Feed it spring thru fall.

Might be pot bound. If you can't manage to transplant into a larger pot (by just 1", so a 16" into an 18 or 20") you can drill 1/2" holes into the root ball and stuff them with compost. You can also take the tree out of the pot, shave the outer inch of roots with something like a bread knife and then repot into the old pot with new soil. I'd also take it outside when the temps are between 55 and 95, and hose it off when you're watering your other plants. You can use a wheelbarrow to move it, or keep it on a saucer with wheels to give your back a break. Ficus are very sensitive to humidity and light, have you moved it recently? You can also prune off the dead parts, but pay attention, there may be tiny green leaves forming at the ends of branches. Once you find where it's happy, it will send out new leaves.

Try replacing the soil or just adding some fresh. It will go into shock when moved or tampered with, so be patient.
