Hoping to identify the type of plant as well as an apparent disease that causes the leaves to grow somewhat sparsely and misshapen. Photos attached. Thank you!
Your plant is called a Ficus Lyrata (Fiddle Leaf Fig). Your Fiddle Leaf is getting sparse probably because it isn’t getting enough light. All sides of this plant need very bright indirect light in order to stay full and bushy. You may have to move your Fiddle Leaf to different locations in your office as the seasons change so that it always has enough light. Without seeing the brown spots in person, there may be a few things I can suggest that may be causing the problem. If there is not enough light, you can get dry brown spots on the older growth. This would go along with the sparse misshapen leaf problem. If your brown spots have gray edges, it is probably a fungal disease called Anthronose or Leaf Blight: remove the diseased Ficus leaves, try to keep water off of the healthy leaves, and increase the air circulation around the plant. You can read all of my care tips for a Ficus lyrata in the Popular Houseplant section of the website.
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. Read more about common houseplants that are poisonous in Don’t Feed Me To Your Cat! A Guide to Poisonous Houseplants
