Symptom: Brown Leaf Tips Possible Causes: Too much fertilizer or pesticides, dry soil, low temperature, hot air, accumulated salts, or root rot. Management: Most indoor plants need to be fertilized only once a month, at most. Stand pots in shallow, pebble-lined trays that are filled with water to increase humidity (pots should sit on the pebbles, above the water line). Once a month, apply enough water to the top of the soil to thoroughly flush excess salts through the drainage hole.
