The leaves of the podocarpus are yellow, what is going on? How can the cause be determined by the sy

Recently, there has been no light supplementation, and there is not much watering, so the leaves are yellow, and it is possible that they are infected with the virus. If the yellowing of the leaves is severe and spreads from the middle to the edges, it means that the virus has been affected.

Lack of water and nutrients and lack of light will cause the leaves to turn yellow, but judging from the yellowing of the light, it is necessary to conduct experiments for each factor, add an ingredient to check the situation, and return to normal, indicating that a certain condition is missing.

There are many reasons why podocarpus leaves turn yellow. If it is due to soil compaction, it is necessary to replace the soil with new soil in time. If it's because of the dry climate, you need to water it regularly to moisturize.

If it is due to a lack of nutrients, it is necessary to dress appropriately during the growing period, but pay attention to the concentration. If it is because of root rot, it is necessary to cut off the rotten roots in time and control the amount of water and fertilizer.

This is because of too much fertilization or too much light. In such a situation, you should learn relevant professional knowledge in time, and you can also go to the Internet to query.

1. Soil compaction.

Long-term irrigation of P. huashanensis with water and fertilizer can easily lead to soil compaction, affecting the respiration of the root system and the infiltration of water. In the long run, it is easy to cause the leaves to turn yellow. In this situation, it is necessary to replace the potting soil in time and replant the loose and fertile new soil, so that the plants will resume their growth and the yellow leaves will disappear.

Second, the climate is dry.

Rohansong prefers a humid climate. If the environment is too dry, it exacerbates the transpiration of the leaves, resulting in rapid loss of water, and yellow leaves will also appear. Therefore, in addition to regular watering, it is also necessary to sprinkle water around the area to improve air humidity.

At the same time, good ventilation is maintained to avoid the growth of bacteria in humid climates.

3. Lack of nutrients.

The growth of Huashan pine requires certain nutrients. If the fertility in the soil is insufficient, plants tend to grow poorly, causing the leaves to turn yellow. The plants are placed in pots and should be given sufficient base fertilizer, generally organic fertilizer. During the growing season, fertilizer should be applied appropriately, but pay attention to the concentration of fertilizer and avoid burning roots.

Fourth, root rot.

If the root system of podocarpus is weakened, the plant's ability to absorb water and nutrients is weakened, and it is easy to turn yellow. For rotten roots, it is necessary to remove the pot and repair it as soon as possible, and do a good job of disinfection to avoid wound infection. The amount of water and fertilizer should be controlled to prevent root rot.

In addition to green chlorophyll, the leaves also contain orange-yellow carotene and yellow lutein, and the decrease in chlorophyll will make the leaves yellow, and the main reasons for the yellowing of the leaves of podocarpus are:

1. The light is too strong, and the light is too strong will cause the burn of the leaves, so that the chlorophyll loses the activity of the slag and makes the leaves yellow

2. Dry yellow section cover, too dry indoors will affect the photosynthesis of plants, affect the synthesis of chlorophyll, and make the leaves yellow and wild

3. Lack of nutrients, plants do not have enough nutrients, which affects the synthesis of chlorophyll and makes the leaves yellow.

Podocarpus is an evergreen plant in all seasons, so it is a common indoor cultivated plant, but it will appear in our cultivation processThe leaves of podocarpus are yellowIn fact, this is a common problem in the process of cultivating podocarpus, so what to do if the leaves of podocarpus are yellow?Below we will bring you the analysis of the causes and solutions of the yellowing of podocarpus leaves, hoping to help you.

What should I do if the leaves of podocarpus are yellow?

Analysis of the causes of yellowing of podocarpus leaves:

If the leaves of podocarpus have a yellowish color and a slight wilting. It may be that there are boring pests in the branches;Whether there is foot rot or other rot diseases in the branches that affect the transport of nutrients and water;Whether the rhizosphere is over-fertilized or the organic fertilizer that is not fully decomposed is applied, causing root rot and affecting the absorption;Whether it is drenched with too much water and poor drainage and rotten roots;Whether the air humidity is not enough due to the high temperature in the planting area, etc., the above are the reasons why the leaves of podocarpus may turn yellow.

Solutions to yellowing of podocarpus leaves:

1. Podocarpus likes fertilizer, should be applied diligently, the fertilizer is mainly nitrogen fertilizer, and an appropriate amount of alum (ferrous sulfate, about 5 grams per plant per year or sprayed with diluent 2-3 times per year) can be added to make alum fertilizer water. Fertilization can be applied once every 1-2 months during the growing period, and fertilization can be combined with watering at the same time (the ratio of water to fertilizer is 9:1).

Potted plants can be sprayed with compound fertilizer or thin cake sedan base liquid water fertilizer each time.

2. Podocarpus is a neutral and negative tree species, which can accept strong light and grow in a shady environment. Although the summer temperature is high and the sun is strong, it is not necessary to shade the podocarpus tree in the summer because it is conducive to maintaining the leaf shape under the conditions of high temperature and strong light. However, due to the tender tissue, the seedlings of podocarpus are not suitable for long-term strong light exposure, so it is recommended to put them in the shade of the tree for maintenance.

3. Podocarpus is not a pine plant and is not drought tolerant. On the contrary, podocarpus is tolerant to shade and dampness, and it is necessary to pay attention to frequent watering during the growth period, but it should not be soaked in water. In the Pearl River Delta region, it is necessary to pay attention to frequent watering on sunny days in summer, generally once in the morning and evening, and often spray foliar water.

Podocarpus is not tolerant to waterlogging, so it is necessary to pay attention to prevent the long sail from accumulating water in time.

The above is what to do if the leaves of the podocarpus are yellow? The entire content of the cause analysis and how to solve it.

Podocarpus is a relatively common evergreen foliage plant in all seasons, often made into a bonsai to appreciate, if there are yellow leaves or falling leaves will reduce its ornamentality, then, what is the reason for the yellowing of podocarpus leaves, what are the reasons, what should we do when we encounter this situation?

The following is Uncle Gardener's analysis of the causes and solutions for the yellowing of the hidden seeds of podocarpus leaves:

1. The impact of pests and diseases.

If there is foot rot, leaf spot, etc., the leaves will be yellow.

Solution: Check whether there are boring pests in the lower branches or roots, prune if the root system is rotten, if it is leaf spot, remove and concentrate on burning the diseased leaves, you can spray 75% Baislow with 500 times of blind fungus clear every other week or so, 25% propiconazole emulsifiable concentrate 1500 times liquid and other fungicides for prevention and control, and spray 2-3 times of continuous alternating medicine.

2. Lack of fertilizer.

Podocarpus likes fertilizer, if it is not fertilized for a long time, then it will have yellow leaves.

Solution: Thin fertilizer is applied frequently, the fertilizer is mainly nitrogen fertilizer, and an appropriate amount of alum (ferrous sulfate, about 5 grams per plant per year or foliar diluent spray 2-3 times) can be added to make alum fertilizer water. During the growth period, fertilization can be applied once every 1-2 months, and fertilization can be carried out at the same time in combination with watering (the ratio of water to fertilizer is 9:

1）。Potted plants can be sprayed with compound fertilizer or thin cake liquid water fertilizer each time.

3. Improper watering.

Podocarpus is tolerant to shade and dampness, but avoid stagnant water, drought or stagnant water will cause yellow leaves.

Solution: You can water frequently, but you only need to keep the potting soil moist and not accumulate water for a long time.

4. Environmental factors.

High temperatures and insufficient air humidity can also cause yellow leaves of podocarpus.

Solution: Do not place podocarpus in an environment with hot air or high heat, if the air humidity is relatively low, you can spray foliar water appropriately.

Picture: Be careful with the maintenance of small potted podocarpus plants.

Tips] If the podocarpus is poorly ventilated, it will be easy to attract insects, and the chlorophyll will be destroyed by long-term shade, and these two conditions will also cause the leaves to turn yellow, so it is best to place it in a place where it can be ventilated and sunny, and do a good job of daily management, so that it can grow better in the air.
