Answer: Browning leaf tips can be due to several factors including overly dry air. Since this is the time of year our winter heating systems are running fairly often, the indoor air tends to be extremely dry. You might try setting it on a tray of pebbles and water (set the pot on the pebbles, add water to just below the top of the pebbles so that the pot is not sitting in water) to try to humidify the immediate area. Also make sure the plant is not in a draft, either hot or cold. Overfertilizing can also cause tip burn, so make sure you are using a water soluble fertilizer formulated for foliage house plants (such as 10-10-10 plus minors) at the lower rate listed on the label; you would not need to fertilize much if at all during the winter months when the days are so short. Cold temperatures can cause tip damage, so keep it in a spot where the minimum temperature is about 65 degrees. Finally, you may be underwatering it. Water thoroughly, then let the soil dry out a bit before watering again. It should not however go bone dry. When you water, make sure it is soaking down into the soil and not just running out between the side of the pot and the soil. I hope this helps!
