Fiddle-leaf figs can be finicky houseplants. You can find full details of the best care routine in our Guide to Ficus lyrata (fiddle-leaf fig) Care.  Too much water is among the most frequent causes of fig tree failure. Water thoroughly, allowing the water to run from the bottom of the pot and check back after 15 minutes to remove any water sitting in the plant's run-off dish.

Wait until the top two inches of soil feel dry before watering again, or until a soil moisture meter inserted near the roots says almost dry.  In its native habitat, the soil drains very quickly and the roots of your ficus will rot easily if over-watered. In the low-light conditions of winter (October through February), your plant may take up water more slowly than during the active growing season. Look out for this change and adjust your watering routine to suit the conditions.

Your plant also needs humidity year round which can be complicated by the challenges of drying winter indoor heat and summer air conditioning. If you can keep the humidity above 40%, that will be enough to prevent brown leaf tips. Stand the plant on a tray of wet pebbles during months of home dryness. If you would like to check whether you are providing enough humidity, you can buy a simple hygrometer (water vapor meter) to keep near your plant.
