What happened to the yellow and brown leaves of Anthurium?

Anthurium andraeanum in many places we can see, Anthurium andraeanum has ornamental, unique flowers, bright color, welcomed by many people. In the cultivation of Anthurium andraeanum, there is often a problem, there will be a problem, that is, Anthurium andraeanum leaves are yellow. The following is to introduce the causes and solutions of the yellowing of Anthurium andraeanum leaves.

Causes of yellowing of Anthurium andraeanum leaves 1. Metabolic normal leaf yellow

If it is found that when the leaves of Anthurium andraeanum are yellow, we should pay attention to the situation of other leaves. If the leaves are fresh yellow-green, and the flowers are growing well, it means that new leaves are growing, and it is normal for old leaves to yellowing and falling.

2. Soil discomfort leads to leaf yellowing.

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. Solution: use oxalic acid and other treatment media and water for watering flowers.

3. Too much watering leads to yellowing of leaves.

The new leaves of Anthurium andraeanum are yellow and the old leaves are normal. In general, 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, hindering normal breathing and absorbing nutrients, causing the leaves to turn yellow and fall off gradually. Solution: watering normally.

4. Dry air leads to yellowing of leaves.

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. Solution: according to the growth characteristics of Anthurium andraeanum, increase the air humidity appropriately.

5. Excessive shading leads to yellowing of leaves.

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. Solution: according to the growth characteristics of Anthurium andraeanum, increase the light intensity appropriately.

6. The temperature should not cause the leaves to turn yellow.

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. Solution: keep the temperature in the greenhouse relatively stable.

7. Uneven fertilization leads to yellowing of leaves.

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.

Solution to yellowing of Anthurium andraeanum leaves

1. When there are yellow leaves in Anthurium andraeanum, we should pay attention to check the rotten roots, and cut them off in time once there are rotten roots.

2. Excessive watering or excessive light can easily lead to yellow leaves and crimping, so pay attention to adjust the position of potted plants.

3. Red palm leaves have wide flowers and large flowers, so you need to wipe the flowers and leaves at the same time when spraying water. Keeping them fresh and clean is the key to plant beauty.

2. the method of soil allocation in the basin.

Anthurium likes soft and fertile soil. Peat soil, leaf bran and perlite are mixed at 3:2:1.

3. Watering to control humidity

It has been introduced to you before that Anthurium likes to be wet, and it is best to keep the basin moist during the dry season in summer and autumn, and usually spray water spray on or around the leaves regularly to increase humidity. Winter is the season for flowering, and Anthurium andraeanum blossoms in winter. Haha, there must be no shortage of water at this time, that is, it is appropriate not to water too much in winter. Remind everyone not to spray water on the flowers when Anthurium andraeanum blossoms, it's easy to break.

4. Fertilizing and replenishing seeds

Anthurium andraeanum fertilization, we should wait until the spring to see the new leaves come out to start fertilization, usually 10 fertilization I almost. When the temperature drops by 15 degrees in the last stage of autumn, we will stop fertilizing. So don't fertilize at the end of autumn, in winter, and in the early days of spring. Anthurium likes fertilizer but can not tolerate too much fertilizer, everything should be moderate.

How is the yellow and scorched edge of Anthurium andraeanum leaves going on?

The leaves of Anthurium andraeanum are yellow and scorched and withered-- their own growth and metabolism

If it is found that the leaves of Anthurium andraeanum are yellow, we should pay attention to the situation of other leaves. If the leaves are fresh yellow-green and the flowers are growing well, it is a normal phenomenon that new leaves are growing and old leaves are yellowing and falling.

Therefore, during the flowering period, remove the old leaves in time and cut off the yellowing leaves. Clean up the dead branches on the surface of the potted soil in time so as not to affect the flowering.

Bacterial infection

Anthurium andraeanum leaves appear yellow, dry symptoms, is likely to be damaged by bacteria. Can be sprayed with 0.3% garlic juice solution, 0.2% vinegar or treated with special agents carbendazim and chlorothalonil.

The leaves of Anthurium andraeanum are yellow and scorched and dry-- the soil is uncomfortable in the external environment.

The soil and water in most northern areas contain more salt and alkali, lack of soluble iron needed for plant growth, and do not change soil for a long time, resulting in the lack of nutrients in the plant, the leaves will gradually lose green and turn yellow.

You can buy professional acidic soil from the florist, or treat the original soil. Oxalic acid is added to the soil to change its acidity and basicity. You can also pour some acidic water every week, dilute it with lemonade or edible vinegar and then pour it.

Air drying

The growth of Anthurium andraeanum needs high air humidity, but when the indoor air is too dry in winter, the leaf tip is dry and yellowing, or the leaf edge is scorched, or the leaf is scorched, the edge is curled and so on.

According to the growth characteristics of Anthurium andraeanum, properly increase the air humidity and often spray to the leaves and the surrounding environment. Keep the plant away from the air outlet of heating and air conditioning as far as possible in winter.

Lack of light

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. During the flowering period, the plant should be maintained in a place with sufficient light and no direct sunlight, which can appropriately increase the light intensity.

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. In winter, people usually move the plants indoors near the doors and windows. Between the doors, the leaves turn yellow when they are hot and cold. Therefore, the indoor temperature should be relatively stable.

The leaves of Anthurium andraeanum are yellow and scorched and dry-- too much artificial maintenance and watering.

The new leaves of Anthurium andraeanum are yellow and the old leaves are normal, which is generally caused by too much water, which makes the soil in the basin too wet for a long time, or even stagnant water, causing part of the fibrous roots to rot, hindering normal breathing and absorbing nutrients, causing the leaves to turn yellow and fall off gradually.

The stagnant water in the basin should be discharged in time. If the plant is in an environment where the soil is too wet for a long time, the plant can be removed from the basin and the soil can be dried and replanted. After normal watering, the leaves will gradually return to green.

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 appear new leaves hypertrophy, uneven, while old leaves dry tip, scorched yellow shedding.

If fertilizing too little, trace mineral elements should be added, and fully water-soluble fertilizers such as "Huaduoduo" can be used. " If the leaves turn yellow due to excessive fertilization, you should stop applying fertilizer immediately and increase watering. In serious cases, part of the old soil can be removed, replaced with new soil, and managed normally after replanting.

What about the yellow and scorched edges of Anthurium andraeanum leaves? what about the hydroponic Anthurium andrographis leaves?

Friends generally think that hydroponic plants are easier to feed, so they turn to hydroponics one after another. in fact, hydroponic plants also have many problems. What if the hydroponic Anthurium andraeanum leaves turn yellow? The following editor will introduce the solution to the yellowing of Anthurium andraeanum leaves in hydroponic culture!

The reason for the yellowing of the leaves of Anthurium andraeanum

In fact, the most important thing of hydroponic Anthurium andraeanum lies in water. Most of the plant nutrients are obtained from water, and some of them rely on photosynthesis to accumulate nutrients. If the water is not added in time in the hydroponic container, the nutrition in the water is not enough, or the light is insufficient, any point will lead to the yellowing of Anthurium andraeanum leaves.

The treatment method of yellowing leaves of Anthurium andraeanum in Water Culture and adding Water in time

Always check the water level in the hydroponic container, when the water level is lower than the root 1 to 3, it is necessary to replenish water in time. As long as there is enough water in the hydroponic container, there is no need to sprinkle water on the leaves every day. If the leaves are dirty, wipe them gently with a wet dishcloth.

Timely addition of nutrient solution

Hydroponic Anthurium andraeanum how much time to change the water does not matter, the key is to grasp the content of the nutrient solution in the water. Over time, water will be absorbed by the plant, and the daily process of adding water has actually completed the step of changing water.

Therefore, in order to ensure sufficient nutrients in the water, when adding water to the container, drop a few drops of nutrient solution. As for the specific number of drops, it can be more flexible according to the growth of Anthurium andraeanum. Drop at least two drops at a time, and then observe the growth of the plant. If it is normal, it will remain intact, and if it is poor, it will be added properly.
