How to Keep Monstera Deliciosa Safe During Winter
As a star variety among tropical ornamental leaf plants, Monstera Deliciosa is deeply favored by green plant enthusiasts for its unique split-leaf shape. However, as winter approaches, how to help this tropical plant survive the cold season becomes a challenge in maintenance. This article will systematically analyze the core points of caring for Monstera Deliciosa during winter, focusing on aspects such as light adjustment and temperature and humidity control.
Adjusting the Survival Environment for Monstera Deliciosa in Winter
Precise Control of Light Intensity
In winter, the sunlight is gentle. It is recommended to move the plant to a south-facing windowsill to ensure it receives 4-6 hours of scattered light daily. Avoid direct midday sunlight and use a shading net with 40% light transmission for regulation. Supplemental plant grow lights can be used when there is insufficient light, with 2 hours of additional lighting daily showing significant results.
Scientific Management of Temperature Gradient
When the environmental temperature consistently drops below 12°C, Monstera Deliciosa enters a dormant state. During the winter, maintain a constant temperature of 15-25°C, with the lowest night temperature not falling below 8°C. In regions with heating, keep the plant more than 3 meters away from radiators to prevent leaf damage from high temperatures.
Practical Points for Caring for Monstera Deliciosa in Winter
Dynamic Adjustment of Water and Fertilizer Supply
Extend the watering cycle to 15-20 days per session in winter, and using the "soak pot" method is more beneficial for root absorption. Adjust fertilization to once a month with a balanced liquid fertilizer diluted 2000 times. Stop any fertilization 7 days before a cold wave arrives.
Humidity Maintenance Techniques
Use an ultrasonic humidifier to keep the air humidity between 60%-70%, and perform foliar spraying between 10:00-15:00 daily. Wipe the leaf backs promptly after spraying to prevent water drops from causing black spot disease. You can also use the ceramic stone water tray method to increase humidity by placing a water-filled ceramic stone saucer under the pot.
Emergency Treatment for Special Conditions
If symptoms of frostbite such as drooping leaves or crispy leaf edges appear, immediately cut off the damaged parts and apply wood ash to the wounds. Move the plant to an 18°C environment to gradually warm up and use plant stress-resistant agents like brassinolide to promote recovery.
By precisely controlling the three major factors of temperature, light, and humidity, combined with scientific water and fertilizer management, Monstera Deliciosa can safely survive indoors in cold northern regions. It is recommended to regularly monitor environmental data with a humidity and temperature gauge and keep a maintenance log to record changes in the plant's condition. Mastering these core techniques will ensure that even in the severe cold of winter, Monstera Deliciosa can maintain its lush green vitality.
