Answer: Anthurium needs warm temperatures and high humidity to stay healthy. Cool temperatures can cause yellowing and dry air can cause browning tips. Try to keep them at a minimum of 70 degrees at night and about ten degrees warmer during the day. Provide extra humidity as our typical indoor heated air is very dry. A humidifier, grouping plants together, and using pebble trays filled with water can all help. Over and underwatering can also cause foliage problems such as you describe. This plant needs evenly moist soil (allow to dry just slightly between waterings) but should not be overwatered, the soil should never be saturated or sopping wet. Overfertilizing can cause problems as well. Often the plants have a slow release fertilizer in the soil mix when purchased so would not need fertilizing for the first few months. Then use a general purpose water soluble fertilizer for foliage plants at half strength or weaker during the growing months of spring to fall. Finally, it needs very bright light but should not be in direct sun; the brightest location you can provide is best. I hope this helps.
