During this season, how to properly care for potted plants to help them survive the cold winter has become a concern for many plant enthusiasts. Here are some winter care tips for potted plants to help them thrive even in the cold winter months.
Lighting
Winter days are shorter with weaker light, so the light requirements for potted plants are relatively reduced. Place your potted plants in a well-lit indoor area, avoiding direct sunlight to prevent leaf burn. Adjust the position as needed to ensure the plant receives even, diffused light.
Temperature
Winter temperatures are lower, and potted plants have varying tolerances. Most potted plants thrive at temperatures between 10°C and 20°C. When growing indoors, keep plants away from cold drafts to prevent frost damage from low temperatures.
Watering
The water requirements for potted plants decrease in winter. Follow the "water when dry" principle—water only when the soil surface is dry. Water thoroughly each time to avoid waterlogging. For cold-hardy plants like pine and cypress, you can reduce the frequency of watering.
Fertilizing
Potted plants grow more slowly in winter and their ability to absorb nutrients is reduced. Fertilize with a low-nitrogen, high-phosphorus and potassium compound fertilizer, and reduce the frequency. Fertilizing once every 20 days is generally sufficient. Be sure to water thoroughly after fertilizing.
Ventilation
Indoor air is dry in winter, and poor ventilation can easily cause potted plant leaves to turn yellow and drop. While maintaining a suitable temperature, ensure proper ventilation to keep the air circulating, which is beneficial for plant growth.
Pruning
Winter is a good time to prune potted plants. Pruning removes diseased, weak, and dead branches, improving air circulation and light exposure for the plant, which promotes growth. After pruning, apply pruning seal to the cuts promptly to prevent infection.
Pest and Disease Control
Winter is a peak season for pests and diseases, especially powdery mildew and scale insects. Regularly inspect your potted plants and treat them promptly if you find any pests or diseases. You can use pesticides for control, but be sure to choose low-toxicity, low-residue options to avoid harming the plants.
Caring for potted plants in winter requires special attention to lighting, temperature, watering, fertilizing, ventilation, pruning, and pest and disease control. As long as you master these techniques, your potted plants will thrive during the cold winter. I hope this information is helpful and wish your plants healthy growth this winter!
