Why do the leaves wither when they wither, and what to do when the tree withers?

Of course, if there is no water, it will shrink, this is not self-protection, but a natural phenomenon, because there is water to make the leaves firm, and without water, of course, it will wilt.

The leaves usually shrivel after losing water and are a form of self-protection for plants.

If the wilting of the tree is caused by rotten roots, the roots need to be pruned, pruned with branches and leaves, and disinfected and replanted. If tree withering is caused by poor maintenance environment, the maintenance environment should be improved in time. If the tree is wilted due to a long-term lack of fertilizer, it is necessary to apply rotten cake fertilizer water every half month during its growth period.

It is mainly caused by the lack of light and poor air circulation. If you keep putting it down, the whole plant may die. It's best to figure out what kind of plant it is, whether it likes shade or yang.

Those who like the sun should often let it bask in the sun in order to grow healthily. As long as the yin-loving ones are often put in the hallway, it's fine.

If only the bottom leaf is withered, it belongs to normal metabolism. The plant absorbs nutrients from the old leaves to supply the growing point, and if the whole plant appears, it may be due to low water supply, atrophy, or too high temperature, and the root system does not absorb enough water.

Pay attention to watering control. It is necessary to see the dry and the wet.

So-called"See Dry"It means that after watering once, wait until the soil surface is white, and the surface and internal soil moisture disappear, and then water the second time, and you can't wait for the potting soil to dry for a long time before watering. The general method is to put your finger inside the soil and feel it dry before watering. If the inside is wet, it is not suitable for continuous watering, which is easy to cause water accumulation in the lower part of the soil, which will seriously lead to root rot.

So-called"See wet"It means that every time you water, you have to water thoroughly, that is, until there is water seeping out of the drainage hole at the bottom of the pot, and you can't water it"Half cut water"(i.e., wet at the top and dry at the bottom), because the roots of a pot of vigorous plants are mostly concentrated at the bottom of the pot and watered"Half cut water"In fact, it is equivalent to not watering.

Adoption"See dry and wet"The method of watering not only satisfies the water required for the growth of such plants, but also ensures the oxygen required for root respiration, which is conducive to the healthy growth of plants.

If there is wilting, you should stop watering immediately, and then put it in a well-ventilated place, away from direct sunlight, and apply fertilizer once a week.

There are three types of plant leaf wilting: lesion wilting, natural wilting, and lack of water wilting.

Judgment method and solution:

1. Observe the soil around the plant, if there is a dry cracking phenomenon and the leaves are wilted in a large area, it belongs to water deficiency wilting;

At this time, the plant should be watered immediately to relieve the symptoms of dehydration.

2. If the soil is moist and the solar term is the harvest solar term of the plant, and the leaves are still tough, it belongs to natural wilting;

At this time, the plant is in normal condition.

3. If the soil is dry and cracked, the normal solar terms factors, the leaves are shriveled and not long, dark yellow and dull, and obviously dry, it is a diseased wither;

At this time, the relevant agricultural should be purchased immediately for the symptoms of the plant.

There are many reasons for the yellowing of plant leaves, too much light will sunburn the leaves of the plant, too high temperature will cause the plant water to evaporate too quickly, too low temperature will cause frostbite to the plant, too much watering will cause the root rot of the plant, too much water will not grow the plant, too much fertilization will burn the roots of the plant, all of these conditions will cause the leaves of the plant to dry up.

Excessive light is the main cause of leaf dryness, there are many trees that are not tolerant of strong light, in the process of summer breeding, if you do not do the corresponding shading measures, strong light will sunburn the leaves of the plant, resulting in its leaves dry up.

For tree breeding, the right temperature is the key to plant growth, different plants have different heat tolerance and cold tolerance, and the temperature of summer and winter has a greater impact on the plant. Long-term high plants evaporate water too quickly, and long-term low temperatures will cause frostbite to the plants, which will cause the leaves of the plants to dry out.

In the process of cultivating potted plants, reasonable watering is very critical, watering should master the principle of seeing dry and wet, and proper watering can be. If you overwater the potting soil, the roots will rot, and if you are too dehydrated, the plant will not be able to grow properly, and the leaves will dry up.

In addition, improper fertilization will also cause the leaves of the plant to turn yellow, we should choose a thin liquid fertilizer when fertilizing properly, if too much fertilizer or too high a concentration of fertilizer, it will burn the roots of the plant, causing its leaves to dry up.
