Causes and Solutions for Yellowing Leaves on the Peace Lily

The peace lily symbolizes its owner's smooth sailing and everything going their way, so quite a few people grow them. But during the process of growing them, the methods used may not be quite right, and the phenomenon of yellowing leaves on the peace lily can appear. Below, let's take a look together at the causes and solutions for yellowing leaves on the peace lily!

Dry air causes yellowing leaves

[Cause of yellowing] The peace lily needs relatively high growing humidity; if the air is too dry, the leaves will wilt.

[Solution] This can be solved by increasing misting or sprinkling water on the floor of the environment. Covering it with a transparent plastic bag also works, but when the light is good, it should be ventilated a little, or a vent should be opened at the top of the plastic bag for ventilation and air flow, otherwise the temperature inside the bag will rise sharply.

Overwatering causes yellowing leaves

[Cause of yellowing] Too much water will affect the plant's root system in carrying out respiration. The peace lily's roots cannot breathe smoothly, which leads to root rot, and the leaves turn yellow and black.

[Solution] Indoors at just over 20 degrees Celsius, it is suitable to water thoroughly once every three to five days.

Nutrient deficiency causes yellowing leaves

[Cause of yellowing] We all know that in the early stage of plant growth, nutrients are absorbed from the soil. Over time, the nutrients in the soil will decrease, causing malnutrition. With too much fertilizer or freeze damage, the leaf tips easily turn yellow.

[Solution] At this point, the soil should be changed immediately. It is recommended to buy humus soil, peat soil and multi-element soil to change the soil for your peace lily.

Improper lighting causes yellowing leaves

[Cause of yellowing] The peace lily needs relatively good light in winter and early spring, and should not be in shade. When the light gradually becomes stronger, it should be gradually shaded. If it is enjoyed in a shaded place, it must not be placed directly in the sun for exposure, otherwise it will show discomfort due to the drastic change in environment, manifested as wilting, yellow leaves, or even death.

[Solution] Keep the peace lily year-round in a spot indoors with bright, indirect light.

Unsuitable temperature causes yellowing leaves

[Cause of yellowing] This generally does not happen easily. Yellowing leaves on the peace lily mostly appear when the temperature is below 5 degrees C or above 35 degrees C.

[Solution] Give it sufficient lighting conditions; this not only helps the leaves stay dark green, but also helps it overwinter.

Improper fertilizing causes yellowing leaves

[Cause of yellowing] Improper fertilizing can also cause yellowing leaves on the peace lily.

[Solution] Fertilize with thin fertilizer; do not apply concentrated fertilizer 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 luxuriantly.

Pest infestation causes yellowing leaves

[Cause of yellowing] If there is damage from mite pests, the peace lily's leaves will show symptoms such as wilting, faded gloss, and yellowing and withering.

[Solution] Spray miticides specialized for killing mites for prevention and control, such as dicofol, hexythiazox, and pyridaben.
