As a favorite among houseplants, pothos is beloved for its unique air-purifying ability and elegant green leaves. As autumn arrives, many pothos owners find that the once-vibrant leaves of their plants begin to turn yellow, which undoubtedly casts a shadow on the joy of raising them. This article will delve into the reasons for pothos yellowing in autumn and provide corresponding rescue measures.
Reasons for Pothos Yellow Leaves in Autumn1. Insufficient Light
In autumn, sunlight gradually weakens. If a pothos is kept in a dim environment for a long time, it can easily cause the leaves to turn yellow. Pothos prefers indirect light. If there is insufficient light, chlorophyll synthesis is hindered, and the leaves will naturally become yellow and withered.
2. Improper Watering
Pothos prefers a moist environment, but the air is dry in autumn. Both overwatering and underwatering can cause leaves to turn yellow. Overwatering can lead to root rot and affect nutrient absorption, while underwatering can cause the soil to dry out, causing the leaves to lose moisture.
3. Temperature Changes
As the temperature gradually decreases in autumn, pothos is sensitive to these changes. Both excessively low and high temperatures can cause leaves to turn yellow. The optimal temperature range for pothos growth is 18-28°C.
4. Improper Fertilization
In autumn, the growth of pothos slows down. Both over-fertilizing and under-fertilizing can cause leaves to turn yellow. Over-fertilizing can lead to excessive salt in the soil, hindering root absorption, while under-fertilizing results in an insufficient supply of nutrients.
Methods to Save Pothos with Yellow Leaves1. Adjust Light
Move the pothos to a location with bright, indirect light, and avoid keeping it in a dim environment for extended periods. Indoors, you can place it near a window, but be sure to avoid direct sunlight.
2. Control Watering
Water the plant according to the soil's moisture level, keeping it slightly moist. As the temperature cools in autumn, you can reduce the frequency of watering.
3. Adjust Temperature
Maintain the pothos's growing environment within a temperature range of 18-28°C, avoiding temperatures that are too low or too high.
4. Appropriate Fertilization
Since the growth of pothos slows in autumn, you can reduce the frequency of fertilization. Choose a fertilizer suitable for pothos and apply it according to the package instructions.
5. Check for Pests and Diseases
Autumn is a high season for pests and diseases. Regularly inspect your pothos and treat it promptly if you notice any signs of pests or disease.
Yellowing pothos leaves in autumn are not a death sentence. As long as you identify the cause and take the right steps, your pothos can bounce back to life. I hope this article helps you solve the problem of yellowing pothos leaves in autumn and allows your plant to continue bringing a touch of green vitality to your home.
