With programmable thermostats, double-paned windows, and other tricks, we are able to keep our homes at the same climatic comfort level year-round. Indoor houseplants, however, can be sensitive to subtle seasonal changes. Even in a balanced home environment, proper winter houseplant care is essential to help plants thrive through this challenging season.
Winter Changes in Home Climates
While the winter changes in our homes are more subtle than the harsh freezes and deep snowfall outdoors, our home environments actually change more than we may realize. Depending on the conditions we like to maintain and the climate outdoors, winter changes may include…
- Fewer hours of daylight, and the daylight that does exist is less intense than during the summer.
- Lower temperatures often accompanied by chilly drafts from windows and doors.
- Lower humidity levels, particularly if central heat has been running, which can dry out air.
These conditions are less than ideal for many houseplants, particularly tropical species that are adapted to longer hours of sunlight, higher temperatures, and richer humidity. Fortunately, with some extra care, winter houseplants can adapt and thrive even during the harshest winter months.
Adjusting Winter Houseplant Care
There are several steps you can take to adjust your houseplant care during the winter. Easy and effective steps include…
- Reducing Watering – Many houseplants go dormant in the winter and require much less water. Overwatering can lead to root rot. Use room-temperature water when watering.
- Reducing Feeding – Plants need less nutrition during winter dormancy. Reducing fertilizer until spring prevents weak, leggy growth.
- Improving Humidity – Use a humidifier, cluster plants, place them in bathrooms, mist frequently, or use pebble trays without letting pots sit in water.
- Relocating Plants – Move plants to south or west-facing windows for better light. Keep foliage from touching cold glass.
- Supplementing Light – Add grow lights when natural light is insufficient. Open draperies and clean windows to increase light.
- Dusting Plants – Clean foliage with a damp cloth or gentle shower so plants can absorb light more efficiently.
- Rotating Plants – Rotate plants every few days to prevent stretching and uneven growth.
- Watching for Pests – Monitor for spider mites, mealybugs, fungus gnats, and other pests. Treat promptly with insecticidal soap or neem oil.
Houseplants offer valuable benefits in winter, helping alleviate Seasonal Affective Disorder and improving mood and well-being. With proper winter care, your plants can remain healthy, vibrant, and inspiring throughout the colder months.
