Pothos was raised to death in the classroom, for what reason

There is a certain possibility that the ambient air is too bad:

Pothos does have a certain effect on absorbing formaldehyde, but the plant itself is small, when the concentration of formaldehyde in the air exceeds the capacity of the plant itself, then the plant will have yellowing leaves, spots, and even fall off and die.

However, the following possibilities are not ruled out:

1. Although pothos is not afraid of shade, a very dark environment will also cause yellow leaves, so you can regularly move the position to a place with good light; At the same time, it should not be exposed to the sun, excessive exposure to strong light will not only cause yellow leaves to fall off, but also lead to the death of the whole plant.

2. Disease: 1) Root rot, due to root rot, the function of absorbing water and nutrients is gradually weakened, and finally the whole plant dies.

2) Leaf spot, a plant disease that mainly occurs on the leaves after being invaded by pathogens.

3) Anthracnose, which mainly occurs on plant leaves, is often harmful to leaf margins and leaf tips, and in severe cases, most of the leaves are blackened and die.

3. Too much fertilization is also easy to cause root burning, resulting in yellowing and wilting of leaves, and the water in the cells will pass through the cell wall, lose outward, and die of dehydration.

Suggestions: 1. Appropriate fertilization with beer, method: Mix beer with water at a ratio of 1:1 and spray stems and leaves.

2. The pothos bought back in winter is generally frozen, so the yellow leaves will soon appear indoors, and after the frozen yellow leaves fall, the Spring Festival will re-issue new leaves.

3. Lack of fertilizer, malnutrition will also appear yellow leaves, at this time fertilizer should be supplemented in time.

4. Generally, the newly bought pothos has an adaptation period of about 1 month to the new environment, and the yellow leaves at the bottom are normal, but remember: the yellow leaves or dead leaves should not be peeled off directly, but should be cut from the middle of the petiole, so as to avoid direct peeling caused by excessive water loss and increased wounds, resulting in the upper leaves will also be yellow.

Here's why:

1. The temperature is not suitable.

The normal growth temperature of pothos is generally about 10-20 degrees, so it is generally not a big problem to raise it indoors, but why it will still be raised to death, the main reason is that it may be close to the heating equipment in summer, such as high-calorie household appliances of air conditioning, which radiates high temperature and radiation to pothos for a long time, so that the pothos does not grow for a long time.

2. Seldom watering.

Pothos is a plant that likes water very much, can not be watered in time, at the beginning there will be yellow leaves, to increase the number of watering, usually a week to water pothos 2-3 times is the best Del, too little will appear lack of water, then pothos will definitely not grow too well.

3. Rarely fertilize.

There are many friends who feel that it doesn't matter whether pothos is fertilized or not, in fact, this is okay, but if your home growth environment is not good, and often no one waters, it is recommended that flower friends appropriately supplement some fertilizer, which is very good for the growth of pothos. However, in winter, pothos grows slowly, so we need to reduce fertilization. After winter, fertilization is mainly foliar spraying.

Pothos (scientific name: Epipremnum aureum), belonging to the genus Epipremnum aureum, belongs to the genus Pyrinophylla, large evergreen vines, grows in tropical areas, often climbs and grows on the rocks and trunks of rainforests, its winding is strong, aerial roots are developed, and can be grown hydroponoically.

Pothos doesn't seem to be able to bask in the sun.

1. Prune the root type leakage.

After the upper part of the pothos is found dead, check the roots for problems. If there are rotten roots and rotten roots, they should be cut off in time, and the excessively long roots should be shortened. After cutting the roots, soak the lower part of the plant in carbendazim for sterilization, usually for about 30 minutes.

If the roots are completely rotten, there is no credible collapse energy to save the plant.

2. Perform beheading.

When the upper part of the plant dies, there is no photosynthesis, but it also wastes water and nutrients in the roots. This is where all the trimming is required. Most of the soil on the top of the pot should be cut off, leaving only 1-2 newly unearthed buds.

3. Change the pot and replant.

Because the rotten roots and branches of pothos can cause bacteria to grow, it is also necessary to change the pot and soil. Choose a moderately sized pot, add crushed tiles or sand to the bottom of the pot to add drainage, and cover with soil. After planting, fill the roots with soil, then compact and water.

Fourth, heat preservation and moisturizing.

After the head is chopped, the potted plant is covered with transparent plastic wrap to help keep the plant warm. You can also make holes in it to help you breathe. Then place in a cool, ventilated place away from direct sunlight.

Fifth, slow seedling maintenance.

During the seedling period, the plants should be reasonably maintained. Watering should be done at once when the soil is white. Do not fertilize, it can cause damage to the new roots. After a week, you'll be ready to sprout. Remove the plastic wrap and place it in an area with astigmatism to help you grow leaves.

1. There is no water change for a long time. The leaves of pothos are needed, and the leaves cannot breathe without changing the water, and they will die if they are soaked in the water.

2. Insufficient light. Although pothos can tolerate shade, it does not like shade conditions, it is still a light-loving plant, but it does not like strong light, and the best conditions for growth are semi-shade or scattered which local light, which is conducive to the normal growth of plants.

Remedy: Cut off the parts that are still alive, change them to clean water, preferably cool boiled water, and insert the base into the water, but do not submerge the leaves into the water. Put it in a place where there is scattered light, and after a week or two, the roots will start to grow again.
