With the improvement of people's living standards, indoor potted plants have become increasingly popular. In winter, when indoor temperatures are relatively low, how to maintain large plants becomes an issue. By mastering the correct methods, it is possible to successfully maintain large frost-resistant potted plants. This article will introduce you to the knowledge related to maintaining large frost-resistant potted plants, helping you to get through a warm winter.

Choosing Frost-Resistant Large Plants

In winter, it is important to choose frost-resistant large plants. Here are some suitable large plants for winter maintenance:

1. Nephrolepis cordifolia: It has strong cold resistance and can be placed indoors in winter, ensuring proper ventilation.

2. Pinus mugo: It is adaptable, frost and drought resistant, and can be placed in a well-lit area indoors in winter.

3. Ficus lyrata: It grows quickly with good cold resistance and can be placed in a warm area indoors in winter.

4. Dracaena: It has strong cold resistance and can be placed indoors in winter with adequate lighting.

Winter Maintenance Tips

1. Control watering: In winter, the temperature is low, and plant growth is slow, reducing water requirements. Watering should be moderate to avoid excessive water that could cause root rot.

2. Increase lighting: Insufficient indoor lighting in winter can lead to yellowing and leaf drop in large plants. You can move the potted plant to a well-lit area or use lights to supplement lighting.

3. Maintain ventilation: Poor indoor air circulation in winter can lead to bacterial growth. It is important to maintain indoor ventilation, reduce humidity, and prevent diseases and pests.

4. Control temperature: Although large plants can withstand the cold, it is best to keep the indoor temperature above 15℃ in winter to avoid frost damage to the plants.

5. Fertilization: As plant growth is slow in winter, fertilization should be moderate. You can apply some compound fertilizers to supplement the nutrients needed by the plants.

Winter Disease and Pest Control

The high indoor humidity in winter can lead to diseases and pests in large plants. Here are some common diseases and pests and their control methods:

1. Mites: Spray insecticide on the plant surface every week, repeating several times.

2. Thrips: Spray insecticide on the plant surface, paying attention to the undersides of leaves, every week, repeating several times.

3. Diseases: When diseases are found, promptly remove the diseased leaves and spray fungicide on the plant surface every week, repeating several times.

Maintaining large frost-resistant potted plants in winter requires certain skills. By choosing frost-resistant large plants, properly controlling watering, increasing lighting, maintaining ventilation, controlling temperature, and preventing diseases and pests, I believe you will be able to successfully maintain beautiful indoor potted plants.
