How can you tell if a plant is starting to die?

There is no way to define the criteria for plant death, because plants have their own growth cycle and the ability of BT to regenerate. The easiest way to judge is to find a branch, break it to see what color it is, if the phloem has no water, it is estimated that it is not far from death. The external manifestations are yellowing and shedding of leaf color, decreased growth rate, and microscopic manifestations are the growth of hormones that cause decline, abnormal respiration, and RNA reduction due to cell senescence, abscisic acid, ethylene, etc.

Pothos this thing, can't be too cold, maybe you freeze people, say that this kind of climbing vine flower cuttings can come to a new one, I wish you pothos full of changes in the garden environment, people have to adapt to it. The yellowing and falling off of the leaves at the bottom is a manifestation of the plant's adaptation to the environment, after all, there is a very big difference between the flower room and the current unheated room, as long as the top can also bud and grow new leaves, then there is no problem. In addition, it is early winter, when the plants are growing slowly and preparing for the winter, the leaves outside are almost gone, and the proper metabolism of the plants in the house is normal.

What is the essence of life, it is a sustainable state of life, that is, he is still in metabolism, and the life characteristics of animals are more obvious, because everyone can move, even if they are about to die, they will twitch twice. Plants are more embarrassing, upright plants will maintain bright green leaves and tall posture, and it is really nerve-wracking to encounter such a strange thing as the Nine Dead Soul Rejuvenation Grass, who knows if he is really dead or fake. The flower pot sprays some water, and he sucks it and turns it green, which means that he is not dead; Carbon 14 tracking, no matter how weak the light and effect, don't try to escape from my eyes, you say that he is a strange ghost orchid, or someone is on vacation; Put on oxygen, close the closed container, check the carbon dioxide concentration from time to time, and have to gasp for breath when you are alive.

Regardless of your animals and plants, carbon dioxide concentrations stop rising. <>

There are many reasons why potted plants often die, in short, they are caused by not understanding the growth characteristics of the potted plants. For example, untimely watering leads to drought death, over-watering leads to anaerobic respiration death of roots, death of low temperature, death of excessive fertilization, death of unsuitable soil pH, death of diseases and insects, and other reasons.

1. If there is a problem with the potted plant due to the application of thick fertilizer or too much fertilizer, you should stop using the fertilizer immediately, and water the soil in the pot with water (water) in time to dilute and dilute the fertilizer, and place the potted plant in a cool place indoors, so that it can recover and grow naturally and slowly.

2. What should I do if the pot has not been watered for a long time and the potting soil is all dry? At this time, you must not be in a hurry, and you must not water it immediately or water it thoroughly. Be sure to water slowly and gradually.

First of all, move the pot to a semi-shaded place, and then water it a little to make the soil in the pot moist. At the same time, spray some water on the leaves of the plant, wait until the stems and leaves stand up, and then water thoroughly to carry out normal maintenance work.

3. What should I do if the potted plants are waterlogged due to too much watering? First of all, pour the plant soil out of the pot and place it in a cool and ventilated place indoors, so that the saturated water in the soil can be quickly dissipated. Increasing the air permeability of the plant can restore the normal activity of the root system faster.

At the same time, spray a little water on the surface of the plant to reduce the consumption inside the plant. It is also possible to spray some fertilized leaf amino acid foliar fertilizer.

Some plants are not suitable for potted plants, some southern flowers are not suitable for growing in the north, some flowers can not be fertilized, and can not be watered too much, do a line to love a line, usually say to cultivate flowers, so be patient, to understand how to raise different plants, for your favorite search, learn hard, you will be able to raise well.

One is that potted plants grow in limited soil.

Second, the growing conditions need to be continuously supplemented with nutrients and water in order to grow well.

Third, the maintenance environment often has factors such as light, ventilation, temperature, and humidity that cannot meet the normal needs.

Watering generally adhere to the principle of "do not dry and do not water, watering is watered thoroughly".

First, can you describe the situation before the wilting, the leaves are yellow or black? Or is the green one just dropping its leaves?

Presumably, most indoor potted plants die from too much water because of the small amount of evaporation indoors, and then, most people like to water it often!

The soil does not have a process of drying and wetting, the roots of the plant are not breathable, and they slowly decay, so they cannot absorb water, and they are waterlogged.

Some plants are not suitable for potted plants, some southern flowers are not suitable for growing in the north, some flowers can not be fertilized, and can not be watered too much, do a line to love a line, usually say to cultivate flowers, so be patient, to understand how to raise different plants, for your favorite search, learn hard, you will be able to raise well.

It is likely to be caused by a lack of water or a lack of a certain nutrient.

There may be pots of small plants that grow larger

It depends on your planting level.

There are many methods, the most commonly used two are two, one is to directly observe the cell morphology with high magnification, the dead cell nucleus becomes larger, the cytoplasm is turbid, and so on.

The other is to stain with neutral red, because of the cell membrane, what can be dyed is dead.

It is judged according to the basic characteristics of life. There is metabolism, the material basis is protein and nucleic acid, there is genetic variation, reproduction, stress, adaptability. Hehe!

Specifically, the cell membrane is selectively permeable to cell survival, so organic dyes are generally not absorbed, so it can be used to identify the dead and alive of seeds (corn for example, the embryo is not dyed red, the endosperm is dyed red), and the plasma wall separation and restoration of mature cells of plants is also possible. Hehe! Methylene blue solution can also be used to identify all metabolic cells.

I believe that many people have gone to the flower shed to buy flowers, do you feel that the air is very humid after entering?

Flower greenhouses generally use translucent shading materials, the air humidity is relatively large, and most of the common indoor cultivated green plants like a warm and humid scattered light environment, which creates good conditions for the growth of flower plants and green plants. On the contrary, the air in the home is relatively dry, and the light conditions are unstable.

When we bring the plants home from the environment they have adapted to before, in order to adapt to the changes in the environment, the plants will have some adverse reactions, such as yellow leaves, dry leaves, falling flowers and buds, and some sensitive plants will also die because of the sudden change in the environment.

Before, what season to choose what flowers, but with the development of the flower industry, now more and more flowers and green plants can appear in the season that people want, especially the New Year's flowers, we all know that the New Year's flowers are artificially controlled temperature and light, promote flowers and flowers, the conditions for flower growth and the family maintenance environment are very different, if there is no rich maintenance experience, the choice should be very cautious. In general, it is also necessary to avoid buying green plants in winter, the temperature is low in winter, the plants are generally in a dormant state, and the rooting and germination are slow. For beginner flower growers, it is best to choose some evergreen foliage plants, which are easy to use.

The green plants in the flower market are generally planted in plastic pots, and many people buy them back for the sake of beauty and will immediately change the pot of the plant, which is beautiful, but it is very easy to cause the death of the plant. As we all know, changing pots is easy to cause damage to the root system, and plants need a slow seedling stage after changing pots. The best way is to water the plant thoroughly, put it in a place with low light indoors, and after a week, if the plant leaves grow normally and there is no wilting and drying, it means that the plant has adapted to the current living environment, and the plant can be repotted at this time.

Many people buy plants on the spur of the moment, simply to dress up the family environment, only pay attention to the appearance of plants, just look good and be beautiful, and do not have an in-depth understanding of the ecological habits of plants. What kind of light plants like, what kind of temperature they like, what kind of water conditions they like, what season they are dormant, and what season they will bloom, these all need us to understand and master, not that there is something wrong with the plant, and then ask everyone why a good plant is dead when it says it dies. There must be a reason for death, and as a conservationist, I didn't even notice it, so it's a little unreasonable to say it.

Create a suitable living environment for plants, so that plants can grow healthily and strongly.

It's not called Qisui like that, except in fables, the quiet death of plants doesn't use the word hail death, <>

Hello! I am glad to serve you to inquire: the tree is dead and weighed as withered, withered is dry, impotence is atrophy, the reason is that the tree has lived to the upper limit of age, or received damage from external factors, so that it can not play its role normally, can not obtain the energy that can survive itself, it will be disturbed by the branches to lose its water, and then lose its vitality, the result can be imagined, there is no water then called dryness, branches and leaves begin to shrink, and finally the finch will wither.

I hope mine can help you and have a great life!

This is a very interesting question, plant cells are totipotent, theoretically, the whole plant body is a loose association, not a tightly organized enterprise like animals, so plants can still regenerate after missing most of the parts, the so-called dead wood in spring is the truth.

Under real conditions, plants will not die to this extent and come back to life. Of course, in most cases, only one branch can be transformed into a whole plant (e.g. willow, moonflower), and one leaf can also be (e.g. begonia).

So is it not true that even if there is no root, it is not true, the air pineapple almost does not have a root, and the tumbleweed has no roots at a certain stage, so this is not a criterion for judgment.

Therefore, I personally believe that the criterion for the death of plants is that all cells can no longer absorb water and mineral nutrients, and if the grain of rice does not enter, then it is really waiting for death.
