Why are the leaves of the Ping An tree turning yellow?

Water yellow

Too much or too little watering

Improper watering is a major reason why the leaves of the peace lily turn yellow. Too much or too little watering may cause the leaves to turn yellow.

Excessive watering will cause water accumulation at the roots of the peace jellyfish, which cannot be fully absorbed, and the soil will not drain well, causing root damage and rot. The characteristic of its occurrence is that there is no obvious change in the old leaves of the plant, while the young leaves turn yellow.

Insufficient watering or excessively hot weather can cause the peace lily to lack water and become dry, causing its leaves to turn yellow. The characteristic is that the leaves are damaged and turn yellow from the bottom to the top, starting with the older leaves.

Solution

Watering must be reasonable, control the amount of watering, do not water too much, it is better to keep the plant moist to prevent root rot.

When the leaves turn yellow due to drought, water the plant in time. Otherwise, the whole plant will wither, fall off, or even die due to lack of water for too long.

Fat Yellow

Fertilization is too concentrated or too weak

Fertilizer is an essential element for plant growth. Too much or too little fertilizer can cause the leaves of the peace lily to turn yellow. Excessive fertilization will cause the young leaves of the peace lily to become enlarged and the leaf surface to become uneven. Insufficient fertilization or too low a concentration of fertilization will result in the fertilization being ineffective, and the yellowing of the leaves of the peace lily will be caused by too long an interval. The characteristic is that young leaves and tender stems turn yellow first.

Solution

If you find that you have applied too much fertilizer, you need to control the fertilizer appropriately. While ensuring that the soil in the pot does not accumulate water, you should water it more appropriately so that the fertilizer can be drained away in time and the fertilizer concentration can be reduced. If the amount of fertilizer is too little, it is necessary to apply fertilizer in time and increase the frequency of fertilizer application, otherwise it will cause yellow leaves on the entire plant or lead to the death of the plant. Be careful not to apply a large amount of concentrated fertilizer.

Iron deficiency

Symptoms of iron deficiency

Iron deficiency in peace lilies can also cause yellowing of leaves. Due to changes in fertilization conditions, the plant's yellowing leaves are serious, with young leaves being more obvious and old leaves being lighter. The leaf flesh turns yellow, and the leaf veins turn green, forming a typical network.

Solution

This situation can be solved by using ferrous sulfate aqueous solution. Mix cake fertilizer, ferrous sulfate and water reasonably and sprinkle them.

Unsuitable environment

Strong light or low temperature

When the light is strong in summer, the scorching sun will cause the leaves of the peace thyme to turn yellow. The yellowing of peace lily leaves is caused by low temperatures in winter, especially outdoors. If the temperature is below 5 degrees, the peace lily will be frozen and its leaves will turn yellow.

Solution

In summer, the peace lily can be placed in an environment with about 50% shading for maintenance. In winter, the peace lily should be moved indoors for maintenance, and the temperature should be kept above 10 degrees, and the number of waterings should be reduced.

soil

Transplanting to a new pot or with poor soil

Generally, when the peace lily is first bought, its leaves will turn yellow due to the soil in the pot.

Since the peace lily needs to be transplanted before being bought and sold, the new pot and new environment will cause the leaves of the peace lily to a certain extent. In order to save soil, some sellers will place some soil debris at the bottom of the pot and cover the top with a layer of soil, which will also cause the leaves of the peace lily to turn yellow and wither.

Solution

The peace lily that you just bought needs to be slowly grown. Place it in a cool and ventilated place for a week before gradually exposing it to light. If you find that there is a problem with the soil, you can remove the soil from the peace lily and pot it, replace it with new soil and replant it.

Other causes

Pests and diseases

Pests and diseases can easily damage the roots of the peace lily, which in turn causes the leaves to turn yellow. Carefully check the growth condition of the peace lily and prescribe the right medicine according to the symptoms. If there is root rot, remove the bad roots, disinfect and replant.

Poor ventilation

The peace lily has certain requirements for its growth environment. It grows better in a ventilated environment. If the growing environment is not ventilated, it is easy to cause the leaves to turn yellow. Therefore, indoor ventilation must be enhanced.

Water quality issues

In terms of water quality, using alkaline water to water the peace lily tree for a long time will cause the leaves to gradually turn yellow and fall off over time. Therefore, when watering, you should pay attention to the acidity and alkalinity of the water, and apply more decomposed organic fertilizers, such as manure, peat, sawdust, edible fungi, etc., to gradually improve the alkaline soil, or directly replace the soil.
