What is the shape of the black pine leaves hanging down, and what is the larch?

Causes of drooping leaves of black pine:1. Improper watering. Black Pine Bonsai Base said that if the leaves of the trees droop, most of the reason is that they are overwatered, causing the plants to absorb too much water, and the leaves will be heavier if they contain too much water.

2. The water and soil are not suitable. Since the black pine is a shallow-rooted tree species, it should not be too deep when planting, otherwise the root system of the tree will not be able to breathe, it will be difficult to absorb nutrients, and the leaves will slowly wither and droop. Therefore, the same is true when planting black pine bonsai, and it should not be planted too deeply.

And trees prefer slightly acidic soil, do not make the soil pH.

Black pine. The main reason for the loss of water in the leaves is that the root system cannot absorb water caused by the excessive wetness of the potting soil or the hard potting soil and produces the phenomenon of leaf water loss, which is easy to cause root rot due to excessive watering, and the rotten root system can not absorb water normally, resulting in leaf water loss, and the potting soil has not loosened the soil for a long time, so that the water after hard watering of the potting soil board is difficult to penetrate into the soil, resulting in a large number of roots in the potting soil can not absorb the water and produce leaf water loss.

Treatment: Insert the pot around the pot with a loosening tool, and gently shake the pot soil to make the pot soil have a cracked feeling, which mainly plays a role in the loose and breathable pot soil and drainage. If the leaves droop due to excessive watering, do not water.

If the water loss caused by the hard potting soil slab, the soil can be loosened and watered thoroughly. Recently, do not bask in the sun to prevent dehydration and death, put it in a sunny and ventilated place indoors to help it resume its growth, if there is a large amount of yellow leaf defoliation, you can use 800-1000 times the liquid of Duoyinling or Tobuzin for whole plant spraying.

Black pine leaf drooping can be due to several reasons:

1.Improper watering: If the leaves of the black pine droop, it may be caused by too much or too little watering.

Overwatering can cause the roots to be overhydrated, making the leaves overly heavy and drooping. On the other hand, if the soil is too dry, the plant will not get enough water, which can also cause the leaves to droop.

2.Unsuitable soil and water: Black pine is a shallow-rooted tree species, if planted too deeply, it may cause the roots to be unable to breathe, difficult to absorb nutrients, and the leaves will gradually turn yellow and droop.

In addition, black pine prefers slightly acidic soils, which can also cause leaves to droop if the soil is too acidic.

3.Lack of light: Black pine is a light-loving plant, and if left in a low-light environment for a long time, it may cause the leaves to droop.

4.Too high a temperature: If the temperature is too high or too low, it may affect the leaves of the black pine, causing the leaves to droop.

5.Pest and disease infestation: If there is an attack on black pine, it may affect the normal growth of the leaves, causing the leaves to droop.

In response to the above possible causes, you can take the following steps to improve the leaf condition of black pine:

1.Control the amount and frequency of watering: Avoid overwatering or underwatering.

If the soil is too dry, you can water it in moderation to make sure the plants have enough moisture. If you find that your roots have a problem with too much moisture, you can try to place the plant in a well-ventilated area to allow the excess water to evaporate.

2.Adjust the soil and water environment: If you find that the soil is too acidic or too alkaline, you can try to replace the suitable soil. When planting black pine, be careful not to plant too deep to ensure that the roots are able to breathe.

3.Provide plenty of light: Place the black pine in a well-lit environment to make sure it can receive enough sunlight.

4.Adjust the temperature: If you find that the temperature is too high or too low, you can place the plant in a suitable temperature environment to help the leaves return to their normal state.

5.Prevention of pests and diseases: Check the health status of black pine in time, and if there is an attack of pests and diseases, you can take corresponding measures**.

These measures can help you improve the condition of the leaves of the black pine and bring it back to life and beauty. If the problem is serious or you are unable to determine the cause, it is advisable to consult a professional horticulturist or botanist for advice.

Larch (Larix spp.)It is a deciduous tree of the genus Pinaceae, which is the main forest component tree species of alpine coniferous forests in Northeast China, Inner Mongolia forest area, North China and Southwest China, and one of the three main coniferous timber forest species in Northeast China. Larch has a wide natural distribution, it is a cold temperate and temperate tree species, the most hardy among conifer species, and the vertical distribution reaches the upper limit of forest distribution.

It is a pine tree that loses its leaves in winter. Commonly known as larch.

The leaves of the black pine tree are lanceolate, and they are as follows: auspicious.
