This time of year houseplants can be struggling with the typical indoor environment; low light, low humidity and either cool or very warm air temperatures. Some plants can tough it out while others aren't so tolerant. Over or under watering is a common issue and can be the death nail for any plant, any time of year.
If possible, move the plant to the sink or shower and water thoroughly to wet the soil. Do this when the soil is dry or every several weeks, depending on the plant, the type of pot and how root bound the plant is. Lift the potted plant after a thorough watering to feel the weight. If it is light the plant needs water. If it is heavy, no water is needed. This is a good way to check for watering anytime. A thorough watering when needed it better than giving a shallow sprinkle every week.
