What to do if the leaves of podocarpus are black? What should I do if the leaves of podocarpus are d

Leads to podocarpus.

There are many reasons for the blackening of the leaves, it is recommended to loosen the soil frequently, make the compacted soil breathable, change the soil regularly every year as it grows stronger, and prune off the damaged and rotten roots. When you find that the leaves are yellow and black, prune off the yellow leaves in time, observe whether the leaves have insect pests, and consult professional flower sellers, purchase the corresponding insecticides and spray them in time, so that they are placed in a sunny and ventilated place to avoid exposure to the sun, keep the soil moist, and should not be watered too much.

Let me start by saying that podocarpus is a neutral species, prefers warm, moist and sunny environments, is drought tolerant, semi-shade tolerant, has a certain cold tolerance, and grows best in loose, well-drained and fertile sandy soils. If the leaves are blackened may be due to overwatering or over-watering, because podocarpus is more drought-tolerant, don't water too much, and it has turned black, consider strengthening ventilation and finding a slightly drier place with good ventilation so that it can breathe freely. Pay attention to fertilization, do not apply too much fertilizer at one time, a small amount of many times, and do not fertilize too often.

Pesticides that can kill aphids. In order to effectively eliminate the pests and diseases of podocarpus, the first thing is to strengthen the daily management of water and fertilizer, strengthen the plants, and improve the disease resistance. The second is to inspect more daily, once there are signs of pests and diseases, treat them immediately, spend less money, and have good results.

Personally, I feel that it is very likely to be the harm of aphids, if it is harmed by aphids, then it is necessary to use 1000 1500 times of imidacloprid wettable powder or 2000 2500 times of acetamiprid emulsifiable concentrate for spray control.

For the tall tree-shaped podocarpus, it can be treated by root irrigation, using 2000 3000 times of imidacloprid wettable powder or 4000 5000 times of acetamiprid emulsifiable concentrate for root irrigation, and the control effect can be maintained for several months or even half a year.

Excessive fertilization, if thick fertilizer is used, bonsai podocarpus can not withstand such a large fertility, so when fertilizing, a small amount of dilution, thin fertilizer is applied frequently, do not fertilize when the temperature is low, and less fertilization should be applied when the temperature is dormant.

The potting soil should not be too wet, especially after the temperature drops in autumn and winter, the potting soil remains slightly dry, if it is watered too much, it will lead to water accumulation and easy root rot. It is also easy to blacken the leaves.

The leaves of podocarpus often turn black, so don't raise them like this in the future.

What kind of fertilizer does podocarpus apply to?

If the leaves of podocarpus are dry and yellow, it is recommended to change the soil as soon as possible due to soil compaction, and replace it with soft, breathable and fertile soil, so as to promote its recovery as soon as possible. If the soil is dry due to lack of water, it is necessary to water and spray it as soon as possible. If it is caused by lack of nutrients, it is necessary to top dressing as soon as possible and apply it frequently with thin fertilizer.

If the temperature is too low in winter due to unsuitable temperature, frostbite, you need to take measures to control the temperature and keep warm as soon as possible.

The yellowing and dryness of the leaves of podocarpus is likely caused by soil discomfort. It prefers soft, breathable, well-drained soil. If the soil has not been changed for a long time during the cultivation period.

If the soil is seriously compacted, it will hinder the respiration of the root system, and the leaves will be yellow and dry after a long time. In this case, the soil should be replaced as soon as possible, cultivated with soft, breathable and fertile soil, and slowly recovered;

Podocarpus prefers a humid environment and has certain requirements for air humidity. If you forget to water for a long time during the maintenance period, the soil is dry, or you are in a dry climate environment for a long time, the root system can not absorb water, and the transpiration of the leaves is strengthened, which will lead to too fast water loss, resulting in yellow leaves and dry leaves. It should be watered as soon as possible to make the soil moister, and it is necessary to spray water frequently to improve air humidity and promote faster recovery;

Podocarpus consumes more nutrients during the growth period, and it needs to be fertilized frequently, especially for potted maintenance. If you don't top dressing for a long time, the soil is poor, you can't absorb nutrients, and you are prone to yellow leaves. It is necessary to top dressing as soon as possible, preferably with diluted fertilizer, which absorbs faster and can help it recover its growth as soon as possible;

Podocarpus prefers a warm environment and has poor cold tolerance. If the temperature cannot be well controlled after winter. Long-term exposure to low temperature is prone to frostbite, yellow leaves, and dry leaves.

Measures should be taken to keep warm and keep warm as soon as possible, the potted plants should be moved indoors, and the roots of the ground plants should be covered with straw and old cotton clothes to raise the low temperature;

By looking at the leaves of podocarpus, you can tell what is going wrong, and timely treatment is the key.

Abstract Hello, a big reason why the stem of podocarpus turns black is because of too much watering, too much watering will cause the branches and leaves to turn black, and even fall down, and the leaves will fall directly down when touched.

You can cut off the blackened branches and leaves, and then loosen the top layer of the soil, and put it in a ventilated place to dry, it is really not possible, you need to change the pot and change the soil, and then disinfect the roots with carbendazim and then plant and maintain it in pots, it will gradually return to normal growth.

Is the same treatment for large podocarpus?

Large podocarpus trees can be cut off from the blackened branches, and carbendazim can be applied at the same time to disinfect and increase soil nutrients.

Tips for dealing with dried leaves of podocarpus:

When the leaves of podocarpus begin to appear yellow and wilted, and the withered leaves gradually increase, it needs to be treated in time. The first thing is to dig the podocarpus out of the potting soil, inspect its root system, and cut off the rotten roots and lifeless roots. Apply carbendazim to the roots and let the wound dry for a few hours.

In addition, cut off some small dry leaves, withered branches, and re-prepare the potting soil, it is best to disinfect the potting soil with carbendazim, and do not add fertilizer to this soil, it is best to be plain soil, or sandy soil, sand. After planting, water the root water once, you can spray a little methyl tobuzin solution, and then put it on the windowsill or balcony in a ventilated and shaded place.

Spray a little water once in a while and let the soil get a little damp. After half a month, it will gradually return to its normal state and grow a lot of young leaves.

Tips and methods for maintaining podocarpus at ordinary times:

Podocarpus likes a cooler and humid environment, so in the summer or early autumn season, when the temperature is too high, Xiaoya suggests that you must not put the podocarpus potted plant under the sun, but need to be placed in a cool and ventilated place, and you need to put it under the awning, or other large plants to block the sun, otherwise the leaves will be dry and yellow and wilted.

When watering, pay a little attention, as soon as the potting soil is dry, you should water it in time, and occasionally spray some water on the leaves, especially when the weather is particularly dry, when the temperature is high, if you do not water for several days, a drought, the leaves will lack water, and the root system will become shriveled, which will cause the leaves to dry up and wither.

If the potting soil is very compact, barren, and not breathable and draining at all, it will not be conducive to the growth of podocarpus. In addition, when fertilizing, the amount of fertilizer must not be too much, using raw fertilizer, too much fertilization will burn leaves and roots, you can use an appropriate amount of trium water-soluble fertilizer.

If you take care of the podocarpus in this way, it will grow lush and beautiful, and the more the leaves grow, the more you grow.

Summary. Hello, the leaves of podocarpus can be caused by improper management, and if the soil used to cultivate it is too compact, or if it is too barren, the leaves will dry up. It prefers moisture, and prolonged drought during growth can cause the leaves to dry out.

There is also in its growth period to fertilize in time, if there is a lack of nutrients, the leaves will dry up due to lack of fertilizer, to do a good job of fertilization and watering at ordinary times.

Hello, the leaves of the podocarpus may be caused by improper management, and if the soil used to cultivate it is too compact, or if it is too barren, the leaves will dry up. It is moist and moist, and a long period of drought during the growth period will cause the leaves to dry out. There is also in its growth period to timely fertilization, if the lack of nutrients, the leaves will be disturbed by the lack of fertilizer dry up, to do a good job of fertilization and watering at ordinary times.

Hello, the leaves of podocarpus are dried up and the remnants of the leaves may be caused by three reasons. One is the lack of light, if it is placed in a dark place for a long time, the photosynthesis will be weakened, and the leaves will dry up. It should be moved to a sunny place and let it bask in the sun.

The second is low-temperature frostbite, which likes warm environments and is not cold-tolerant. If the temperature is not controlled in winter, it will be frostbitten and the leaves will dry up. The third is the lack of nutrients, the nutrients consumed in the peak growth season, if not timely top dressing, easy to grow poorly, the leaves will be yellow, dry up.

Can you change the pot now?

Hello, yes, pay attention to maintenance.

1. Be sure to prune the rotten branches and leaves in time, after all, the existence of these branches and leaves will only consume nutrients and affect the beauty of the ornamentation.

2. After taking out the roots, repair them with scissors in time to remove the rotten roots, and then apply carbendazim to the wound and put it in a cool place for 24 hours, and then reformulate the new soil, so that the plant can have stronger growth and will soon exude vitality.

3. Check whether the potting soil is breathable, if you see that the soil has agglomeration, the performance of ventilation and drainage is not strong, so you need to replace the new soil in time, otherwise it is easy to have stagnant water when watered, and the roots will easily rot. When turning the pot, you can put some tiles at the bottom, so that you can have a more prosperous growth.

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 should I 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 to 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 excessive fertilization or insufficient organic fertilizer is applied in the rhizosphere, resulting in root rot and affecting absorption; Whether it is drenched with too much water and poor drainage and the roots are rotten; 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.
