Winter can be a challenging time for houseplants, as the cooler weather, lower light levels and dry air (from the heating) can cause them to become stressed and unhealthy. But with a little care and attention, you can help your plants thrive throughout the winter months.
One of the most important things you can do for your houseplants during the winter is to provide them with adequate light. Ambient light levels in winter are much lower and so you need to move your plants into more light. Place them near a window that receives plenty of indirect sunlight, or use grow lights if you don't have a suitable window.
Proper watering is also crucial for keeping your plants healthy over winter. Water your plants regularly, but allow the soil to dry out much more between waterings. Lean on the side of keeping the plants drier rather than wet. Overwatering can lead to root rot very quickly in cooler temperatures and darker light levels, so be sure to check the moisture level in the soil regularly.
In addition to light and water, your plants also need consistent temperatures and adequate humidity to stay healthy. Keep the temperature in your home within the range recommended for each plant species, and increase the humidity by misting your plants with water, using a humidifier, or placing them on a tray of moist gravel. If you don't have these, simply grouping them together can help create localised humidity.
Finally, protect your plants from drafts, which can cause them to dry out or become damaged. Move them away from doors, windows which may be opened, and heating vents.
By following these simple tips, you can help your houseplants thrive throughout the winter and enjoy their beauty all year long!
