Answer: You might take a close look and see if there are any signs of insects on the leaves or stems. You might see flat disks (scale) or tiny insects and fine webbing (spider mites). If you do, they can both be controlled with insecticidal soap applied according to the label instructions. You might also want to make sure it is not pot pound. If you see roots escaping the drainage hole and roots are filling the pot, then you may need to repot it. You might also do what you can to increase the humidity, either by running a humidifier, grouping plants together, or setting the pot on a pebble tray. (Place pebbles in a tray or saucer, fill with water to just below the tops of the pebbles, set the pot on the pebbles.) In the meantime, keep the soil evenly moist but not sopping wet and use a water soluble fertilizer for foliage plants according to the label instructions. Finally, if you just recently purchased the plant and it was accustomed to lower light levels at the store, it may be "sunburning" in your bright window. If you think this is a possibility, set it in a more moderate spot and then gradually acclimate it to the light level in the location where you want to keep it.
