Houseplants are as varied as people and their specific winter care is dependent on their variety. In general though, most houseplants enter a type of dormancy in the winter months marked by a decreased rate of growth and no active flowering. Because of this, they need less water and fertilizer.

Humidity levels, already low in our dry Colorado air, are even lower in winter. This is exacerbated by indoor heating systems which can cause greater air turnover and subsequently dry out these plants. Increasing the humidity level will reduce or prevent the characteristic browning of the leaf margins. To increase the humidity levels around your houseplants, place them on pebble trays or group them together. The most effective way, though, is to add a humidifier. The upside is that the moisture will be good for you too. Your skin will thank you!

You may need to change the location of your plants as well. Move tropical plants away from vents and all plants from your fireplace mantel if you intend to use your fireplace. A cool north window in the summer may be a bit too cold in the winter for tropicals. Think about putting plants that require a dormant period there instead.
