Six reasons for yellowing of Anthurium andraeanum leaves how to maintain the yellowing of Anthurium andraeanum leaves

Anthurium andraeanum is a kind of high-grade potted plant, many people like to cultivate this plant, not only because it looks good, but it can also improve the home environment, but the leaves of Anthurium andraeanum also turn yellow. Let's take a look at the six major reasons why the leaves of Anthurium andraeanum are yellow. how to maintain the yellowing of Anthurium andraeanum leaves.

What if the leaves of Anthurium andraeanum turn yellow?

1. Anthurium andraeanum is a tropical flower that likes high temperature and cold, likes shade and avoid sun, likes dampness and avoids drought. At ordinary times, you should be careful not to be exposed to the sun, and do not put it in an environment with strong direct sunlight. Anthurium andraeanum leaves yellowing how to do, but also can not be placed in the dark room for a long time, should be placed in a bright place with scattered light.

2. The requirements of Anthurium andraeanum for watering are: dry and then water, and water thoroughly. I don't know how long your Anthurium andraeanum has been bought, but the yellowing of the leaves may be the reason why they are not dry and watered too often.

In addition, Anthurium andraeanum needs to be fertilized in about two months, and the leaves may turn yellow without fertilizer. It is best to use special fertilizer for Anthurium andraeanum when fertilizing, and regular manufacturers will mix fertilizer when buying Anthurium andraeanum. The growth temperature of Anthurium andraeanum should not be lower than 15 ℃, otherwise the leaves and stems are easy to turn black.

3. Environmental prevention: strengthen the control of the temperature in the greenhouse (the ideal breeding condition of bacteria is about 30 degrees), the sanitary environment and the flow of personnel and working tools in the production area.

4. Fertilizer prevention: try not to use high NH4 nitrogen fertilizer in plant growth. Go to or isolate the diseased plant.

Leaf blight nematode is caused by nematode infection of the genus nematode, mainly infecting roots and leaves. The disease is characterized by the formation of necrotic spots or brown spots along the veins, the root is enlarged, and finally the whole leaf dries up.

The main methods of prevention and control are to strengthen seedling quarantine, select robust seedlings and do a good job in the disinfection of cultivation substrate.

5. Control of soil PH value. Anthurium andraeanum is a kind of flower species which is sensitive to salt. therefore, the pH value of the substrate should be controlled between 5.2 and 6.1 as far as possible. What if the leaves of Anthurium andraeanum turn yellow? If the pH value is too small, the flower stem becomes shorter, it will reduce the ornamental value.

Tap water is suitable for planting Anthurium andraeanum, but the price is expensive; natural Rain Water is the best water source in Anthurium andraeanum cultivation. Potted Anthurium andraeanum has different water requirements at different growth and development stages.

6. Maintenance details; yellow leaf phenomenon of Anthurium andraeanum, mainly caused by rotting roots caused by low temperature; too much fertilizer and water, which hinders the metabolism of Anthurium andraeanum; overwatering will also yellowing the leaves of Anthurium andraeanum; too much light will make the leaves of Anthurium yellowed and lose luster, and it will also lead to slow growth of Anthurium andraeanum, short leaves, small leaves and curl The reason for exuberant growth but not flowering is generally caused by too dark placement and too much nitrogen fertilizer.

The reason for the yellowing of Anthurium andraeanum leaves 1. To water too much:

Too much water and too much water will make the medium in the basin too wet for a long time, or even stagnant water, causing some fibrous roots to rot, hinder normal breathing and absorption of nutrients, and cause leaves to turn yellow and fall off gradually. Preventive measures: normal watering.

The reason for the yellowing of Anthurium andraeanum leaves 2. Uneven fertilization:

Little fertilization, or no change of soil for a long time, lack of nitrogen and other nutrients in the soil led to thin branches and leaves, thin and yellow leaves. In addition, excessive fertilization will also lead to the thickening and uneven of new leaves, and the dry tip and scorched yellow of old leaves will fall off at the same time. At this time, we should immediately stop fertilization, increase watering, remove part of the old soil, replace it with new culture soil, and carry out normal management.

The reason for the yellowing of Anthurium andraeanum leaves 3. The temperature is not suitable:

If the indoor temperature is too low in winter, the leaves will turn yellow; if the room temperature is too high, the plant transpiration is too high, and the root water and nutrients are insufficient, the leaves will turn yellow. Preventive measures: keep the temperature in the greenhouse relatively stable.

The reason for the yellowing of Anthurium andraeanum leaves 4. Soil discomfort:

There are more salt and alkali in the medium and water in most areas of the north. Due to the lack of soluble iron that plants need to absorb in the medium, the leaves will gradually lose green and turn yellow. Preventive measures: use oxalic acid and other treatment media and water for watering flowers.

The reason for the yellowing of Anthurium andraeanum leaves 5. Air drying:

When the air of indoor flower cultivation is too dry in winter, the leaf tip is often withered and yellowed, or the leaf edge is scorched, or the leaf has scorched spots, edge curling and so on. Preventive measures: according to the growth characteristics of Anthurium andraeanum, increase the air humidity appropriately.

The reason for the yellowing of Anthurium andraeanum leaves is 6. Excessive shading:

If Anthurium andraeanum is placed in the shade or in a place with insufficient light for a long time, it will lead to weak growth, thin and yellow leaves, no flowering or rarely flowering. Preventive measures: according to the growth characteristics of Anthurium andraeanum, increase the light intensity appropriately.
