More and more people are growing peace lilies, and you have to admit that just hearing its name makes you want to grow one, because the peace lily carries a beautiful blessing. But in the process of growing a peace lily, what should you do when its leaves turn yellow?
Key Points for Growing a Peace Lily
The peace lily can basically adapt to both strong and weak light, growing well from full sun to very dark spots, and is suitable for indoor placement. But if you want it to bloom more, give it more light; during the growing season, bright light is better, but in the height of summer avoid direct harsh sun, otherwise the leaves will turn yellow, and in severe cases sunscald will appear; from May to September provide a sufficient water supply so the soil stays consistently moist, and frequently spray water on the leaves and the surrounding environment to raise humidity. Fertilize once every 10 to 15 days, especially during the flowering period and when new leaves emerge, mainly with nitrogen fertilizer. Move it indoors at the beginning of November; in winter, keep the room temperature at around 12°C and give it good light, otherwise the leaves will turn yellow, affecting the next year's growth and ornamental value.
Causes of Yellowing Peace Lily Leaves
1. Overwatering
Too much water affects the plant's root respiration; the peace lily's roots cannot breathe properly, leading to root rot, and the leaves turn yellow and black.
2. Dry air
The peace lily needs relatively high growing humidity; if the air is too dry, the leaves will wilt.
3. Nutrient deficiency
In the early stages of growth, the plant absorbs nutrients from the soil; over time, the nutrients in the soil decrease, causing malnutrition. Too much fertilizer, or cold damage, also makes leaf tips turn yellow easily.
4. Improper lighting
The peace lily needs fairly good light in winter and early spring, so do not keep it in shade, and as the light gradually intensifies, shade it gradually. If it is kept in a shaded spot, do not put it directly in the sun to bake, otherwise the sudden change in environment will cause discomfort, shown as wilting, yellow leaves, or even death.
5. Unsuitable temperature
When the temperature is below 5°C or above 35°C, peace lily leaves easily turn yellow.
6. Improper fertilizing
7. Pest infestation
If there is damage from mite pests, the peace lily's leaves show adverse symptoms such as wilting, dulled gloss, and yellowing and withering.
What to Do When Peace Lily Leaves Turn Yellow
Today we will teach you some remedies; see which cause applies to the peace lily you are growing, and the corresponding measures are as follows:
1. Improper lighting. The peace lily needs fairly good light in winter and early spring, so do not keep it in shade, and as the light gradually intensifies, shade it gradually. If it is kept in a shaded spot, do not put it directly in the sun to bake, otherwise the sudden change in environment will cause discomfort, shown as wilting, yellow leaves, or even death.
2. Humidity: The peace lily needs relatively high growing humidity; if the air is too dry, the leaves will wilt. This can be solved by spraying more water or sprinkling water on the floor of the surrounding environment. Covering it with a transparent plastic bag also works, but when the light is good, ventilate it slightly or cut an opening at the top of the plastic bag for ventilation, otherwise the temperature inside the bag will rise sharply.
3. Improper fertilizing. Fertilize with dilute fertilizer; do not apply concentrated or raw fertilizer, and after applying solid fertilizer, water once with clear water. It is best to use dilute fertilizer water instead of clear water for watering; this generally will not cause fertilizer burn, and the plant will grow lushly.
4. Unsuitable temperature. This situation generally will not happen at this time; it mostly occurs when the temperature is below 5°C or above 35°C. 5. Pests. If there is damage from harmful mites, the leaves show adverse symptoms such as wilting, dulled gloss, and yellowing and withering; you can spray miticides specifically for mites, such as dicofol, hexythiazox, and pyridaben.
Tips for Growing a Peace Lily
1. Indoors at around 20-plus degrees Celsius, it is suitable to water thoroughly once every three to five days.
2. If the air is dry, this can be solved by spraying more water or sprinkling water on the floor of the surrounding environment. Covering it with a transparent plastic bag also works, but when the light is good, ventilate it slightly or cut an opening at the top of the plastic bag for ventilation, otherwise the temperature inside the bag will rise sharply.
3. When there is nutrient deficiency, change the soil immediately. It is recommended to buy leaf mold soil, peat soil, and multi-element soil to repot your peace lily.
4. Keep the peace lily year-round in an indoor spot with bright, indirect light.
5. Make sure the temperature does not drop below 5 degrees, and in winter place it in a warm spot with sunlight.
6. Fertilize with dilute fertilizer; do not apply concentrated or raw fertilizer, and after applying solid fertilizer, water once with clear water. It is best to use dilute fertilizer water instead of clear water for watering; this generally will not cause fertilizer burn, and the plant will grow lushly.
7. After pests appear, you can spray miticides specifically for mites, such as dicofol, hexythiazox, and pyridaben.
From the above introduction, you surely know now how to solve the problem of yellowing peace lily leaves!
