Why are the leaves of the Phalaenopsis orchid becoming very thin?
The thinning of Phalaenopsis orchid leaves is caused by excessive water, insufficient light, lack of nutrients, and unsuitable temperature. When watered too much, the plant's roots cannot breathe and absorb nutrients and water, causing the leaves to become thin. Insufficient light and lack of nutrients cause the leaves to stop growing, and unsuitable temperatures further affect the plant's development.
1. -- Excessive Water --
When the Phalaenopsis orchid is watered excessively, its roots cannot breathe properly and cannot absorb water and nutrients from the soil, leading to thin leaves. Therefore, it is necessary to control the amount of watering to keep the soil moist without causing waterlogging, and to ensure timely drainage during rainy days to prevent root rot.
2. -- Insufficient Light --
Phalaenopsis orchids require ample light for growth. When light is insufficient, the plant's photosynthesis slows down, and the leaves become thin. In such cases, it is necessary to increase the duration of light exposure, placing the plant outdoors or on a balcony for care, and using grow lights to supplement light when sunlight is insufficient.
3. -- Lack of Nutrients --
When the Phalaenopsis orchid lacks nutrients for a long time, the plant gradually stops growing, and the leaves do not have the nutrients to continue developing, so they become thin and soft. To prevent this, it is necessary to apply sufficient base fertilizer and top-dress with phosphorus and potassium fertilizer or decomposed organic fertilizer every two weeks to ensure adequate nutrients.
4. -- Unsuitable Temperature --
Phalaenopsis orchids are intolerant to both high and low temperatures. Therefore, when the temperature fluctuates too much, the leaves cannot grow normally and will gradually become thin. In summer, it is important to sprinkle water around the plant to cool it down, and in winter, it is best to move it indoors for care, which is more conducive to keeping warm.
