Philodendron 'Imperial Green' is a relatively high-end foliage plant, but its care can be a challenge. Especially in winter, due to lower temperatures, it can easily lead to slow growth or even death of the plant. Today, let's explore how to scientifically care for Philodendron 'Imperial Green' to keep it healthy and thriving during the winter.
Choose a Suitable Light Environment
The light environment is very important for the growth of Philodendron 'Imperial Green'. In winter, sunlight is scarce, so it's necessary to choose a relatively well-lit location to place the plant. At the same time, be careful to avoid direct sunlight to prevent the plant from getting injured.
Control the Temperature
The suitable growth temperature for Philodendron 'Imperial Green' is 15°C to 25°C. In winter, if the ambient temperature is too low, measures need to be taken to keep it warm. You can use tools like an electric blanket for heating. However, be careful to avoid overheating to prevent scorching the plant.
Regular Watering
In winter, the plant grows slowly, so the frequency of watering needs to be reduced. Generally, watering once every 7 to 10 days is sufficient. However, be careful to avoid overwatering to prevent root rot.
Maintain Humidity
The air is dry in winter, which can easily cause the leaves of Philodendron 'Imperial Green' to wither. Therefore, it is necessary to frequently spray water to increase the air humidity. At the same time, covering the surface of the potting soil with a layer of moist plastic film or materials like grass ash can also help retain moisture.
Fertilizer Use
In winter, Philodendron 'Imperial Green' grows slowly and does not require excessive fertilizer. Generally, fertilizing once a month is sufficient. Choose a suitable fertilizer and apply it correctly according to the instructions.
Remove Fallen Leaves and Pests/Diseases
Fallen leaves and pests/diseases can affect the plant's growth, so they should be removed promptly. Especially in winter, due to slow growth, fallen leaves and pests/diseases are more likely to proliferate. Regular inspections and timely treatment are necessary.
Pruning
Proper pruning can promote plant growth, but pay attention to the methods and timing. In winter, avoid excessive pruning to avoid affecting the plant's growth.
Pay Attention to Repotting
Repotting is not recommended in winter. If it is absolutely necessary to repot, be sure to keep the plant warm and moist to avoid causing significant damage.
Proper Shading
In winter, due to scarce sunlight, Philodendron 'Imperial Green' is susceptible to damage from the sun. Therefore, proper shading is needed, but be careful not to block too much light to avoid affecting the plant's normal growth.
Do Not Apply Too Much Ammonium Oxalate
Ammonium oxalate is a fertilizer that promotes plant growth, but improper use can damage the plant. In winter, Philodendron 'Imperial Green' grows slowly and does not need excessive ammonium oxalate. It should be applied correctly according to the instructions.
Pay Attention to Wind Protection
The wind is strong in winter, which can easily cause the plant to topple over. Therefore, wind protection is necessary, especially for Philodendron 'Imperial Green' placed outdoors.
Avoid Strong Light Exposure
Strong light exposure can easily cause leaf scorch on Philodendron 'Imperial Green'. Therefore, avoid strong light exposure, especially in locations like south-facing windows.
Regular Repotting
Philodendron 'Imperial Green' generally needs to be repotted once a year to ensure its growth. Repotting is not suitable in winter; it is better to do it in the spring.
Pay Attention to Plant Arrangement
In winter, the arrangement of plants can also affect their growth. The leaves of Philodendron 'Imperial Green' should not be crowded together; maintain good ventilation.
Philodendron 'Imperial Green' is a relatively high-end foliage plant with high requirements for light, temperature, water, and other aspects. In winter, it is also necessary to pay attention to issues like keeping warm and maintaining humidity. Only by providing scientific and reasonable care can Philodendron 'Imperial Green' grow healthily and thrive in the winter.
