CLEVELAND — As winter's chill settles in, many houseplants struggle to adjust to lower light levels and drier indoor air. While winter may seem like a dormant season for plants, with the right care, they can thrive indoors even with frigid temperatures outside. Here are key tips to help your houseplants survive and flourish during the colder months.
Provide sufficient light
In winter, daylight hours are shorter and the sun's rays are weaker, so it's important to reposition plants to maximize the available light. Move them closer to windows, or consider adding a grow light.
South-facing windows generally provide the best light, while east or west-facing windows offer moderate exposure. Rotate plants every few weeks to ensure even light distribution.
Adjust watering routine
During winter, most houseplants go into a dormant state, meaning their growth slows down and they require less water. Overwatering is a common mistake at this time of year, leading to root rot.
To avoid this, check the moisture level of the soil before watering. If the top few inches of soil feel dry, it's time to water. If not, wait a few days. Always ensure pots have proper drainage to prevent excess water buildup.
Increase humidity
Dry indoor air caused by heating systems can make it tough for plants to thrive in winter. Many plants, especially tropical varieties, prefer higher humidity levels. To help, consider using a humidifier or place plants on trays filled with pebbles and water.
Another simple solution is to group plants together, which creates a microclimate with higher humidity. Mist your plants with water occasionally, but avoid over-wetting the leaves, as this can lead to mold growth.
Keep plants warm, but not too warm
Most houseplants prefer temperatures between 60 and 75 degrees Fahrenheit, with cooler conditions at night. Keep plants away from heat sources, such as radiators, space heaters, and drafty windows. Cold drafts can cause leaf damage, while direct exposure to heat can dry out leaves and soil.
On the flip side, if your home tends to get very cold, consider moving your plants to a warmer room or adding an extra layer of insulation to keep the temperature stable.
Avoid fertilizing
During winter, many plants enter a period of dormancy, slowing their growth. As a result, they don't need as much nutrition.
Avoid fertilizing plants until spring, when they start actively growing again. Fertilizing during the winter can lead to nutrient buildup in the soil, potentially harming your plants.
Watch for pests
Even in winter, pests like spider mites, aphids, and mealybugs can still thrive indoors. Inspect plants regularly for any signs of infestation, such as discolored or damaged leaves.
If you notice any pests, gently wipe the leaves with a damp cloth or use an insecticidal soap. Be sure to isolate affected plants to prevent the pests from spreading.
Prune and clean
Regular pruning not only keeps your plants looking tidy, but also promotes healthy growth. Trim off any dead or damaged leaves, which can attract pests or fungi. Additionally, wipe down the leaves with a soft, damp cloth to remove dust, which can block sunlight and reduce the plant’s ability to photosynthesize.
By adjusting your plant care routine to fit the season, your houseplants will remain healthy and vibrant throughout the winter months. With the right attention, you'll enjoy a thriving indoor garden, even as the weather outside turns cold.
For more specific care instructions, it's best to research the particular needs of each plant variety.
