Hi Jacqueline,

There are several things that could be causing the problem.

Cold temperatures: Fiddle Leaf Figs do well in temperatures between 60°-80°F (15.5°-26.7°C). Keep the Fiddle Leaf and all ficus away from air conditioners, drafts, and heating vents.

Fertilizer: Fertilize a Fiddle Leaf Fig monthly in the spring and summer using a basic houseplant food at 1/2 the recommended strength. Too much fertilizer when the plant is not actively growing causes leaf burn (brown leaf edges). Do not feed during the fall and winter.

Water: A Lyrata, or Fiddle Leaf Fig, requires less water than other ficus trees. Allow at least the top 50% of the soil to dry out and the leaves to become soft and flexible before watering. Once the soil has dried out, water well until the water comes out the drip holes in the bottom of the pot. Do not allow the plant to sit in water. When plants are over-watered, older leaves and those at the bottom of the stems turn brown and fall off.  To make things really confusing, when the plant does not get enough water, the new leaves turn brown and fall off. From the way the roots are bulging, I’d say it was over watered.

Light: A Fiddle Leaf Fig requires bright indirect light. Insufficient light causes small new growth and leaf drop. Turn a Fiddle Leaf  Fig frequently to keep it growing straight. Too much sun causes the leaves to fade and lose their dark green color.

These plants are considered poisonous and should be kept away from pets and children. The sap of a Fiddle Leaf Fig plant is very irritating so use gloves when working with this plant.
