Help me please! My friend’s life may depend on it!

I have a plant which I rescued from a friend who had pretty much killed him and left him to die, so naturally I asked if I could take him on, and he graciously accepted.
He came back to life with the help of splints and love, and got some nice new leaves. The photo I’m sending is taken from his heyday in my care, but now he’s lost a lot of leaves and the ones he does have are brown at the edges and he looks somewhat sorry to be honest. I don’t think all is lost, but he’s certainly not well. In fact I’ll send one of him now, too. Basically, all I want to know is what he’s called and if I can save him!
If you can help, and even if you can’t, thank you for your time!!
Sincerely,
Bryan

Hi Bryan,

Your plant is a type of Calathea. Calatheas usually get brown edges when they need more humidity, when you are giving them too much plant food, or when the water you are using contains too much salt, fluorine, of chlorine. You can read all my care advice for Calathea houseplants in the Popular HousePlant section of the website. The Calathea pictured there is of a different variety, but the care instructions are the same.
