As winter settles in, your houseplants may seem like they're in hibernation, but they're still very much alive and need attention. While the outside garden takes a break, the plants you’ve brought indoors require some TLC to ensure they thrive throughout the colder months. January is the perfect time to refresh your plant care routine and give your green friends a little extra love.
Adjusting Watering Needs
In the winter, plants typically need less water than during the growing season. Lower light levels and cooler temperatures mean that the soil in your pots dries out more slowly, so it’s important to avoid overwatering. Check the moisture level of your soil by sticking your finger about an inch deep. If it feels dry, it’s time to water; if not, hold off. For plants in lower light conditions, reduce the frequency of watering even further to prevent root rot.
Light is Key
Indoor lighting can be a challenge in the winter months. Your plants may not be getting as much sunlight as they did during the longer days of summer. To help them cope, try moving your plants closer to windowsills where they’ll get the best light. If you find that natural light is still lacking, consider investing in a grow light or even grow bulbs for your existing fixtures. Even a few hours a day under artificial light can make a significant difference for your plants.
Watch Out for Pests
While you might not think about pests during the winter, they can still be an issue, especially when plants are brought inside. Keep an eye out for spider mites, aphids, and mealybugs, which tend to thrive in dry indoor air. A quick rinse with water or a gentle wipe down with a soapy cloth can help keep them at bay. For more persistent infestations, consider using an insecticidal soap or neem oil or a change of soil.
Don’t Forget About Humidity
Indoor air tends to dry out during the winter months due to heating systems, which can be tough on houseplants—especially tropical varieties that thrive in higher humidity. To help them stay healthy, consider using a humidifier or grouping your plants together to create a naturally humid microclimate. Be mindful of drafts and avoid placing plants near vents, heaters, or even heat-emitting electronics, as these can dry them out further. Another simple option is to place a shallow tray of water nearby or set your pots on a pebble tray filled with water. As the water evaporates, it will increase moisture around your plants’ leaves.
Fertilization: Take a Break
In the winter, your plants’ growth slows down significantly. This is not the time to fertilize. Giving them a break from fertilizers ensures they aren’t overfed during their dormant period. Wait until spring when you see new growth to start your regular feeding schedule again.
Repotting in January? Consider it Carefully
If you’re thinking of repotting your houseplants in January, be mindful that they might not be actively growing. Repotting can stress them out, as they aren’t in their peak growth phase. If you must repot, do it sparingly and only for plants that have outgrown their pots or show evidence of advanced pest or soil problems.
