Are you a proud plant parent? Do you want to ensure the health and well-being of your houseplants during the winter months? Look no further! In this article, we will discuss the best practices for seasonal care to help you maintain the health and happiness of your houseplants through the winter. From adjusting watering routines to providing adequate light and humidity, we’ve got you covered. Let’s dive in!

Adjust Watering Routine

During the winter, most indoor plants go into a dormant state and require less water. Overwatering can lead to root rot and other complications. It is essential to adjust your watering routine accordingly. Here are some tips to consider:

  • Check Soil Moisture: Before watering your plants, check the moisture level of the potting mix. Insert your finger about an inch or two below the surface. If the soil feels dry, it’s time to water. However, if it is still slightly moist, hold off on watering for a few more days.

  • Decrease Frequency: Since plants are in a resting phase during winter, they don’t need water as frequently. Reduce the number of times you water your houseplants compared to the warmer months. Typically, watering once or twice a month should be sufficient for most plants.

  • Water Adequately: While the frequency of watering decreases, make sure to water your plants adequately when it’s time. Ensure the water reaches the plant’s roots, but avoid leaving the plant sitting in excess water, as it can lead to root rot.

Provide Adequate Light

With shorter and darker days during winter, it’s crucial to provide your houseplants with as much light as possible. Here are a few tips to keep in mind:

  • Maximize Sunlight: Place your houseplants near windows that receive the most sunlight. South-facing or west-facing windows tend to provide the brightest light during winter. Rotate your pots a quarter turn each week to ensure all sides of the plant receive an equal amount of light.

  • Supplement with Grow Lights: If your home lacks natural sunlight, consider using artificial grow lights. LED grow lights are energy-efficient and can provide the necessary light spectrum for plant growth. Position the lights close to the plants and set a timer to mimic natural light cycles.

  • Avoid Drafty Locations: While it’s important to provide enough light, be cautious about placing plants too close to drafty windows or doors. Cold drafts can stress and damage plants, so find a balance between sunlight and protection from chilly air.

Increase Humidity Levels

The dry indoor air during winter can be challenging for houseplants, especially those native to tropical regions. Here are some ways to increase humidity levels for your plants:

  • Cluster Plants Together: Grouping your plants together creates a microclimate that helps increase humidity. As plants release moisture through evaporation, the surrounding air becomes more humid.

  • Pebble Trays: Place your plants on trays filled with water and pebbles. The water in the tray will slowly evaporate, raising the humidity around the plants. Be sure the pots are elevated above the water level to prevent root rot.

  • Humidifiers: Consider using a room humidifier to maintain a higher humidity level for your houseplants. Humidifiers are especially beneficial if you have a large collection of plants or live in an area with very dry air.

Adjust Temperature and Avoid Extreme Conditions

Extreme temperature fluctuations can stress and harm houseplants. It is crucial to keep your plants away from sources of temperature extremes, such as cold drafts, heat vents, radiators, and direct contact with windows.

  • Ideal Temperature Range: Most houseplants thrive in temperatures between 65 to 75°F (18 to 24°C) during the day and above 50°F (10°C) at night. Some plants may tolerate slightly cooler temperatures, so it is essential to research the specific requirements of your houseplants.

  • Protect from Cold Drafts: Be cautious about placing plants near windows that experience cold drafts during winter nights. Move them away from these areas or use curtains or blinds to act as a barrier.

Pause Fertilization

During their dormant phase, houseplants do not require as much nutrients as they do during the active growing season. It is advisable to pause fertilizing your plants during the winter months. Here are some key points to remember:

  • Natural Resting Period: Most houseplants naturally rest during winter, which means they aren’t actively growing. Withholding fertilizer allows the plants to conserve energy and prepare for new growth in the upcoming spring.

  • Resume in Spring: Once the days start getting longer, and you notice new growth appearing on your plants, it’s time to resume fertilizing. Start with a diluted dose of fertilizer and gradually increase the frequency as the plants enter their active growing phase.

Monitor for Pests and Diseases

Winter can be a vulnerable time for houseplants, as pests and diseases can become more prevalent. Stay vigilant and regularly inspect your plants for signs of infestation. Here’s what you should do:

  • Regular Inspections: Regularly examine the leaves, stems, and soil surface of your houseplants for any signs of pests or diseases. Common pests during winter include aphids, scale insects, and spider mites.

  • Treat Infestations Promptly: If you detect any pests, it’s crucial to take action promptly. Treat infestations using appropriate methods, such as insecticidal soap or neem oil. Follow the instructions on the product label and repeat treatments if necessary.

Maintain Clean and Dust-Free Foliage

Dust and grime can accumulate on the leaves of houseplants, reducing their ability to photosynthesize. Keep your plants’ foliage clean and healthy with these tips:

  • Regular Dusting: Use a damp cloth, a soft brush, or specially designed microfiber dusting gloves to gently wipe the leaves. Pay attention to both the upper and lower surfaces of the leaves.

  • Rinsing in the Shower: For large or delicate plants, rinsing the leaves with room-temperature water in the shower can effectively remove dust and refresh the foliage. Allow the plants to drain before returning them to their usual location.


Maintaining the health of your houseplants through the winter months is essential for their long-term survival and growth. By adjusting watering routines, providing adequate light, increasing humidity levels, and implementing other seasonal care practices, you can ensure your plants thrive even in the coldest months. Remember that different plants may have specific needs, so it’s crucial to research their individual requirements. With the right care and attention, your houseplants will continue to bring beauty and joy into your home throughout the winter season.
