What s going on with the yellow leaves of the boxwood, the fallen leaves, and the withered tips

1 Causes of dry leaves of boxwood trees.

When the leaves of boxwood trees dry out, it is mostly due to improper water and fertilizer or environmental factors. In general, if the leaves of the boxwood tree are dry, it can be saved, as long as the roots do not wither, the boxwood tree can still live.

At this time, we need to find the cause of the dry leaves of the boxwood tree first, and then treat the symptoms according to different reasons. If the root system of the boxwood tree dies, the boxwood will gradually dry up because the leaves cannot absorb nutrients.

2. What to do if the leaves of the boxwood tree are yellow.

Overwatering: If the boxwood is overwatered, it will cause the boxwood leaves to turn yellow, which is characterized by the fact that the old leaves of the boxwood do not change significantly, but the newly grown leaves will turn yellow. At this time, the solution is very simple, that is, you need to control the moisture.

Too little watering: If the boxwood leaves turn yellow from the bottom up, it may be caused by a lack of water. If the water shortage is too long, it can even lead to the death of the whole plant. The solution to this situation is the need for timely watering.

Nutrient insufficiency: Insufficient nutrients in boxwood can also lead to yellow leaves, and if this is the case, then the young leaves and young stems of boxwood will turn yellow first. When this happens, it is necessary to apply fertilizer in time, but it is necessary to pay attention to thin fertilizer and frequent application, so as not to cause root burning.

If the fertilizer is too much, stop the fertilizer immediately, then water it with large water to reduce the amount of fertilizer, and then move it to the sun to dry;

Boxwood likes to be moist, and the maintenance environment must be ventilated, if the ventilation is too poor, it will affect the growth of the plant. When maintaining the plant, move the plant to a sunny place so that the plant can grow more robustly. If the environment is not ventilated and the potting soil is still moist for a long time, then the plant will be prone to root rot.

Whether it is strong or weak light, high or low temperature, too much water or drought, insufficient or excessive fertilizer, pesticide damage, bacterial disease, or combined with yellowing virus, or the soil pH value is wrong, there should be no other conditions.

If the boxwood is overwatered, it will cause the boxwood leaves to turn yellow, which is characterized by the fact that the old leaves of the boxwood do not change significantly, but the newly grown leaves will turn yellow. At this time, the solution is very simple, that is, you need to control the moisture.

<> poplar tree got the medicine that killed the tree two months ago, and then it was alive and well, and now it has grown leaves, and in the past two days, the leaves have withered, and the hail socks have wilted and widened, does it have anything to do with this medicine?

Hello, yes, there is a relationship. The poplar tree was masked because it had been treated with drugs two months ago, which affected the growth and metabolism of the internal panicle of the tree, and eventually caused the leaves to wilt. It is recommended that you ask a professional horticulturist or botanist to come for examination in time and give corresponding ** and care.

At the same time, in the future plant care, it is necessary to avoid the use of inappropriate or excessive drugs to protect the health of the plant.

The yellowing of the leaves of the poplar tree is the yellowing of the seedling.

There are generally only a few reasons for this:

1. Stagnant water. Long-term water accumulation at the roots of poplar trees leads to such a situation, and it is enough to make drainage ditches in the field.

2. Fertilizer and burn seedlings. When fertilizing the water, it did not keep up in time. In such a situation, after the rain, I will slowly get better.

3. Pest and disease hazards. Mainly leaf mites, spraying drugs to kill red spiders can be done.

Methods for the prevention and control of leaf spot, rust, scab, downy mildew and other diseases of jujube, apple, pear and other fruit trees:

At the beginning of the disease, spray 800 times 80% mancozeb wettable powder (Aino Aisheng) + 1000 times "Tianda 2116" (special type for fruit trees), 1 time every 10-15 days, 2-3 times in a row, pay attention to alternate use with Bordeaux liquid.

Usually apply water-soluble fertilizer to enhance resistance.

If the leaves of poplars are yellow, if they are infected with yellowing, they can be sprayed with ferrous sulfate and urea solution**.

The soil is not fertile enough to cause the poplar leaves to turn yellow, you can supplement some iron-rich organic fertilizers to make the poplar leaves more green, and at the same time, you can also add a certain quality of ferrous sulfate to the soil, so that the soil has more nutrients, and effectively prevent and control the yellow leaf disease of poplars.

Send a ** to see, this description is too general.

1. Boxwood stem base rot.

In the investigation, it was found that boxwood stem base rot did not attract the attention of gardeners, and was always ignored, because the initial stage of the disease was mainly manifested as individual dry branches and dead leaves that were easily mistaken for drought or not completely transplanted to survive, so many times they were allowed to develop, and the best prevention and control period was missed, so that the disease spread more and more in the later stage, and finally a large number of boxwood plants dried up and yellowed and died.

2. Harm plants.

Through long-term investigation and analysis in many places, it was found that boxwood stem base rot not only harmed large-leaved boxwood, but also harmed holly plants such as melon seed boxwood, Phnom Penh boxwood, and bird's-tongue boxwood.

3. Causes of the disease.

High temperature and humidity are external environmental factors for the occurrence of diseases. The fungus is the causative agent of the disease, the pathogen mainly lives in the soil, with the increase of soil temperature, the fungus begins to infect the rhizome parts of seedlings, especially in the high temperature and low-lying areas.

4. Symptoms of harm.

Large-leaved boxwood stem base rot is the main hazard.

The incidence of first- and second-year-old shoots and newly transplanted boxwood seedlings is also higher. In the early stage, the stem of boxwood turned brown, and in the later stage, the damaged part of the stem base turned black, and the cortex shrank, and the xylem color was brown after the cortex was peeled off, and the xylem was gradually deepened from the outside to the inside by transverse incision, and the pith became black in severe cases. With the increase of temperature, the damaged part develops rapidly, the germ invades the xylem, the color of the xylem first changes from brown to black, and the germ invades the xylem, resulting in the death of the whole plant.

5. Prevention and control methods.

1.Strengthen the maintenance and management of seedlings, and drain low-lying places in time to prevent the occurrence of diseases induced by high humidity.

2.In summer, small seedlings should be shaded or planted under large trees to achieve the purpose of cooling.

3.Pharmaceutical prevention and control. When diseased plants are found in the nursery or in the green belt, clean them up in time, and use fungicides such as carbendazim and dimethazim to irrigate the roots, or you can choose a special fungicide to water the roots of Lane Ping'an Yuyuan 1-15 times, or adjust the nozzle of the sprayer to the direct spray mode, and spray it on the rhizome part, which must be sprayed evenly and thoroughly.

6. Summarize that high temperature and high humidity are the external factors that induce the outbreak of the disease, we should pay attention to creating appropriate temperature and humidity to reduce the occurrence of the disease in our daily maintenance work, spray fungicides before the arrival of the high temperature and high humidity season, do a good job of prevention, and observe and deal with the disease in time to minimize the harm of the disease.

The causes of yellowing and drying of boxwood leaves are too low temperature, excessive watering, reduced light, and improper fertilization.

1. The temperature is too low

When cultivating boxwood, it is necessary to take cold and warm measures in time when encountering a low temperature environment, otherwise it is easy to cause the leaves to turn yellow and fall. If the temperature is lower than 0°C, it will also cause frostbite in the potting soil, and the cells of the plant will die one after another, and in severe cases, the whole plant will die. In response to this situation, some cold protection measures need to be taken.

If it is a home-grown boxwood, it can be moved indoors for maintenance.

2. Overwatering

Overwatering can also cause the leaves of boxwood to turn yellow. Overwatering can lead to water accumulation in the pot, which will further rot the root system of the plant and cause yellowing of the leaves. If it is in the growing season, it is necessary to appropriately reduce the amount of watering and reduce the frequency of watering, and it is best to choose a tile pot with good drainage for farming.

In winter, it is necessary to pay attention to reducing watering, otherwise it is not conducive to the growth of plants.

3. Reduce light

Sunlight is indispensable for the growth process of boxwood, and insufficient light can cause the leaves of boxwood to turn yellow. It is necessary to extend the sunshine time appropriately, and in summer and noon, it is necessary to shade at the right time, and avoid direct sunlight.

4. Improper fertilization

Boxwood likes fertilizer, but if the concentration of fertilizer applied is too high, it will cause the problem of burning roots and yellowing of leaves. If too little fertilizer is given to the boxwood, the lack of nutrients will also cause the leaves to turn yellow. For yellowing of leaves caused by high concentrations, it is best to move the plants to a new potting soil.

If the leaves are yellow due to insufficient nutrients, they need to be fertilized in time. In the process of breeding boxwood, we should pay attention to "thin fertilizer and more application", and must not apply thick fertilizer.
