Why Do Houseplants in winter Need Special Care in Winter?
Houseplants experience slower growth in winter due to reduced light and lower humidity levels. Common problems include yellowing leaves, dry soil, and pest infestations. Adjusting your care routine can help your plants stay healthy until spring.
1. Adjust Watering Routine
Overwatering is the most common mistake in winter plant care. Since most houseplants grow more slowly in the colder months, they require less water.
- Check the soil before watering. Stick your finger about an inch deep—if the soil feels dry, it’s time to water.
- Use room-temperature water to avoid shocking the roots.
- Water less frequently, but deeply. Instead of frequent light watering, ensure water reaches the roots when needed.
- Reduce watering for dormant plants. Cacti and succulents require significantly less water in winter.
2. Increase Humidity Levels
Indoor heating systems create dry air, which can cause leaf browning and crispy edges. Many houseplants in winter, especially tropical varieties like ferns, peace lilies, and orchids, need extra humidity in winter.
- Use a humidifier near your plants to maintain moisture levels.
- Group plants together to create a natural microclimate.
- Mist plants lightly, but avoid excessive moisture that could lead to fungal issues.
- Place a pebble tray with water under plant pots to increase humidity naturally.

3. Provide Adequate Light
With shorter days and weaker sunlight, houseplants in winter may struggle to photosynthesize effectively. If your plants show signs of light deficiency, such as yellowing or leggy growth, try these solutions:
- Move plants closer to windows. A south or east-facing window provides the most natural light.
- Rotate plants regularly to ensure even light exposure.
- Use grow lights if natural light is insufficient. LED grow lights can supplement winter light needs.
- Clean windows and plant leaves to maximize light absorption.

4. Keep Plants Away from Drafts and Heat Sources
Temperature fluctuations can stress Houseplants in winter, leading to leaf drop and weakened growth.
- Keep plants away from radiators, heaters, and fireplaces. Excess heat can dry out soil and leaves.
- Avoid placing plants near drafty windows and doors. Sudden cold air exposure can shock sensitive plants.
- Maintain stable indoor temperatures. Ideally, keep temperatures between 60-75°F (15-24°C).
5. Reduce Fertilizing
Most houseplants in winter enter dormancy in winter, meaning they require fewer nutrients.
- Pause or reduce fertilization. Too much fertilizer can cause weak, leggy growth.
- Resume feeding in early spring when plants begin to show new growth.
- For winter-flowering plants, such as Christmas cactus, use a diluted balanced fertilizer sparingly.
6. Monitor for Pests
Pests like spider mites, fungus gnats, and scale insects thrive in dry indoor conditions.
- Check leaves regularly for pests or webbing.
- Wipe leaves with a damp cloth to remove dust and potential pests.
- Use neem oil or insecticidal soap if infestations occur.
- Isolate infected plants to prevent spreading.
7. Give Plants a Rest
Since houseplants in winter are a period of slow growth, avoid repotting or pruning aggressively.
- Hold off on repotting unless a plant is severely root-bound.
- Prune only to remove dead or damaged leaves.
- Let your plants rest and focus on basic care.
Conclusion
Caring for houseplants in winter requires small adjustments to ensure they stay healthy until spring. By reducing watering, increasing humidity, providing adequate light, and keeping them away from temperature extremes, you can help your plants thrive. Keep a close eye on them and adjust care as needed to enjoy lush, vibrant greenery year-round.
