I have a tricolor stromathe. I love it, mine is taller and the foliage is thinner than pictures Ive seen. Also, The leaves are turning brown on the edges. This cant be from underwatering because I keep the soil moist. Also I know that the stromanthe likes partial shade so I dont have it in any windows, which may be the problem. I dont know. I also though it could be because of the humidity level in my home is so dry, so I made my plant pebble tray. There is some new growth but I dont want to lose my new leaves. What can I do? Here is a picture of my plant.
