What if the tip of the leaves of Ping an is blackened, caused by flooding / lack of light (including countermeasures)

Ping an tree is famous for its large leaves, which can grow to 10-22 cm and have a metallic luster, so it is highly ornamental when placed indoors or outdoors, but some people will encounter the phenomenon of blackening and mildew of the leaves, which seriously affects the beauty of the tree. what about the black tip of Ping an leaves? What if the leaves of Ping an tree are moldy? The editor sorted out the main reasons and solutions for everyone.

What if the tip of the leaves of Ping an tree is black?

There are three main reasons for the blackening of the leaves of Ping An Tree, namely: improper watering, lack of light, diseases and insect pests. Therefore, when solving the problem of blackening the leaves of Ping An Tree, different measures need to be taken according to different situations.

1. Improper watering

Watering is a very important link for planting any plant, and the requirement for water content of Ping An Tree is not too low. If too much watering will lead to flooding of roots, the phenomenon of blackening of leaf tips and drooping of leaves will occur. We have introduced how to do with drooping leaves of Ping An Tree before, and the solution to blackening caused by watering is as follows.

Solution: Pour out the accumulated water in the pot soil, stop watering and wait for the pot soil to dry slightly before watering. It is necessary to pay attention to the use of dry and wet exchange to keep the pot soil moist.

2. Lack of light

Although the peace tree has a happy negative, but it also needs enough light, many people often put it indoors and the light is not sufficient, it may lead to blackening of the leaf tip, at this time the peace tree leaf tip black how to do? The method is as follows.

Solution: Move it to a ventilated and light-transmissive place. If it is in summer, do not move it directly to the outside, as long as there is enough light. If it is in winter, do not put it in a cool and hidden place.

3. Caused by diseases and insect pests

Pests and diseases are one of the main culprits affecting the health of Ping An tree, and it is also one of the reasons for blackening the leaf tip. For example, brown spot disease will cause brown spots on the leaves, and then small black spots will appear. Therefore, it is necessary to do a good job in pest control of Ping An tree.

Solution: If the tip of the leaf due to pests is black, the diseased leaves should be removed first, then sprayed with professional drugs, and the rotten roots should be cut off, and replaced with clean fresh soil, and gradually the tree will return to normal.

What about the peace tree leaves?

Under normal circumstances, moldy leaves are caused by pests and diseases. What should be done at this time is to carry out prevention and control. The correct practice is as follows:

1. Apply the disinfectant to the leaves;

2. Spraying special pesticides for prevention and control;

3. Loose soil. Available loose soil tools inserted around the basin, and then gently shake the basin soil, is the basin soil can have a gap, so that the soil can be better permeability;

4. Move the tree to a ventilated place and water it properly. After the moldy problem has been alleviated, spray it with white signs and then water it heavily. Pay attention to ensuring that it can be poured thoroughly. Stop watering after spraying with moisture.

Summary: Whether the leaves are black or moldy, it is a very headache. In addition to mastering the correct cultivation method of the peace tree, it is necessary to treat the black and moldy plants. As long as the method is correct, it can make the peace tree rejuvenate.

How to do when the leaves of the peace tree droop, watering/soil change/temperature control can return to normal

Under normal circumstances, the leaves of the peace tree are tall and shiny, but sometimes they may encounter drooping leaves, so what about the drooping leaves of the peace tree? Need to understand the cause of its droop, and then take the appropriate measures to make it normal.

What about the peace tree leaves?

The growth of the leaves of the peace tree will be affected by many factors, so there are many reasons for its drooping, so what about the drooping leaves of the peace tree? As long as we find the cause, we can really solve the problem, and in the process of leaf drooping, it is divided into normal drooping and abnormal drooping. Here we will introduce it from these two aspects.

I. Normal droop

The so-called normal drooping means that it is not caused by the cultivation method of Ping An Tree. For example, it is normal for the newly bought Ping An Tree to droop due to the replacement of pot soil. You can check whether its roots have rotten roots and blackening signs. If not, it is not drooping due to pathological changes.

Coping method: Put the peace tree in a ventilated place and water it. The principle is to irrigate the soil thoroughly, keep the whole flowerpot moist, and at the same time let the excess water be removed from the bottom. Do not let the basin accumulate water. Generally, after 1 day, the drooping leaves can be improved.

II. Abnormal droop

1, caused by light

The normal growth of peace trees requires sufficient light. If they are placed in an environment with insufficient light for a long time, they will cause their leaves to droop.

How to deal with it: Move it to a window or balcony, and shade it in summer.

2. Temperature

We know that the optimum temperature for peace trees is 20-30 degrees, and if the temperature is too low or too high, it may cause the leaves to droop.

Coping method: observe the temperature of the environment where the tree is located. If it is too cold or the temperature is too high, adjust the ambient temperature in time.

3, caused by excessive watering

Ping An Tree likes a humid environment, so its requirements for moisture are high. Frequent watering is one of the methods, but sometimes because too much watering will lead to problems at its roots, such as rot, etc., which will produce a series of chain reactions. The intuitive feeling is that the leaves droop.

Coping method: When watering the peace tree, be sure not to overdo it, ensure that the pot soil is moist, and do not pour too much water at one time. In winter, less watering can be done by spraying water.

4. Caused by too high soil alkalinity

Although the requirements of the peace tree for the soil are not high, but prefer acidic soil, for alkaline soil may not adapt to the situation, so planting peace trees in the north is easy to appear leaf droop, at this time peace tree leaves droop how to do? The answer is to change the soil or water strategy.

Coping methods: When watering, acidic substances can be added to the water, such as ferrous sulfate, vinegar, etc. After a period of time, the acidity in the soil will increase, and the leaves will gradually return to normal.

Summary: Leaf drooping is caused by light, temperature, soil and watering problems. Of course, this situation may also occur in the newly bought peace tree. In the face of these problems, we should find out the cause as soon as possible, and then take reasonable measures to avoid drooping phenomenon.

The ecological habit of kidney bean tree likes the environment of high temperature and humidity, sunshine foot; high temperature tolerance, cold intolerance, suitable humidity, avoid dryness, born in valley or flat sparse forest. The cultivation of kidney bean trees should be loose, fertile, well-drained, rich in organic matter loam and sandy loam. The cultivation technique temperature of kidney bean tree likes warm and hot environment, and the suitable temperature for growth is 20℃ to 30℃. During the summer heat, when the ambient temperature reaches above 30℃, it is necessary to properly shade the canopy, increase the environment and spray water on the leaves, or move it to a ventilated and cool place with shade for summer. Fall late autumn, when the ambient temperature dropped to about 10℃, it should be moved to the shed in time. During the winter, it is best to maintain the greenhouse temperature not lower than 8℃, and the minimum temperature shall not be lower than 5℃, so as to avoid cold damage to leaves or fallen leaves. Family potted plants can be moved indoors with air conditioning or electric heaters to ensure that the room temperature is not lower than 8 ° C so that they can survive the winter safely. Note: In winter, the temperature of the greenhouse for planting kidney bean trees should be kept not lower than 8℃, otherwise it is easy to have cold damage or even death of the whole plant. Light kidney bean tree is a light-loving plant, but also a little shade, full sunlight, semi-shade environment can be. Its seedlings are more tolerant of shade, summer to build a shed shading. Potted plants should be placed in front of a well-lit window or indoors during indoor display. If it is placed indoors in dim light for a long time, it is easy to cause falling leaves. Family potted plants, during winter can be placed in front of the window or balcony before the higher parts, so that it can receive more light. Water cultivation of kidney bean trees requires a relatively moist soil and display environment. Seedling period, to keep the seedbed moist, summer after the high temperature and drought season, more attention should be paid to water supply. Potted kidney bean tree, in order to make it not grow too tall, in the spring when the new shoots, can be properly controlled watering, maintain the pot soil can be relatively moist. In addition to keeping the pot soil moist, the potted plants displayed indoors should be sprayed with water 2 to 3 times a day in high temperature seasons. Summer, autumn put in outdoor maintenance of plants, must strengthen the plant and the surrounding small environment spray, for its creation of a cool and humid suitable environment. Winter placed in the indoor plants, because the general indoor temperature is lower than 10℃, the plants into a dormant state, not too much watering, so as not to appear water rotten roots, can be every 2 days to 3 days in fine weather around noon, with a little warm water spray plants once, in order to maintain its delicate appearance, but also increase the environmental humidity. In addition, kidney bean trees can also be hydroponic. Potted kidney bean tree soil, should choose loose fertile, good drainage permeability, rich in organic matter culture soil. Usually 5 parts of garden soil, 3 parts of rotten leaf soil, 1 part of decomposed organic fertilizer and 1 part of river sand are mixed and prepared. During the growing season, loosen the soil once a month to ensure that the roots are always in a good state of permeability. During plum rain season, potted plants placed in the open air should be checked in time after each heavy rainfall. If there is accumulated water in the basin, it should be removed as soon as possible, and the basin should be turned over and replaced after the soil is dried. Under normal circumstances, small and medium-sized plants as family potted plants can be turned over once a year at the beginning of April to meet the requirements of soil fertility for their annual growth. Fertilizer potted kidney bean tree, in addition to the requirement to add appropriate amount of decomposed cake fertilizer and 3% of the multi-element compound fertilizer in the culture soil, but also should be given continuous topdressing. During the growing season, quick-acting liquid fertilizer can be applied once a month, usually with decomposed cake fertilizer water. A small amount of potted plants in families, or large-scale potted plants displayed in public places for a long time, can be regularly buried with a small amount of multi-element slow-release compound fertilizer particles, or can be irrigated with 0.2% urea plus 0.1% potassium dihydrogen phosphate mixture. Potted in northern China, 0.3% potassium dihydrogen phosphate solution can be continuously applied for 2 to 3 times after Mid-Autumn Festival to increase the cold resistance of plants and help them survive the winter safely. When the temperature is higher than 32℃ in summer and lower than 12 ℃ in late autumn and early winter, topdressing should be stopped. The propagation method of kidney bean tree can be sown at the end of December. When the capsule is close to dehiscence and the seed is fully mature, the elongated capsule is harvested, the winged seed grains are detached after drying, the membranous seed wing fragments are removed after kneading, and the dry storage is carried out until the next spring. It can also be soaked for 2 to 3 hours and then mixed in wet sand, thinly spread in a large plastic basin in the shed, keep the seed and sand moist, check frequently to prevent mildew, and sow on the ground after the seed germination. The dried seeds are soaked for 3 to 4 hours from March to April, then taken out and aired slightly, mixed with sand and spread on the prepared seedbed, lightly covered with thin soil, covered with thin film to keep moisture, removed after the seeds emerge, and shaded by a sparse shade. For sale. Cutting March to April, when the ambient temperature reaches about 15℃, cut 1 - 2 years old lignified branches, about 15 cm to 20 cm long, delete all leaves, the best incision is located at 0.5 cm below the node, cutting it on the sandy soil seedbed, cutting into the soil depth of about 1 /3 to 1/2 of the ear length. During the period of its undercutting healing and rooting, water should be sprayed to keep the seedbed moist. After it grows a complete root system, it can be transplanted to the pot with soil mass, preferably 2 to 3 plants, which can be formed and sold as soon as possible. The layering can be carried out in a ring under the nodes of 2-year-old strong branches or stems from March to April, and the peeling width is generally 2 to 3 times the diameter of the stems. Tie a 15 cm x 20 cm piece of plastic film under the girdling opening. The water mouth, and tie it against the thick trunk, to prevent drooping by the wind break. At the end of autumn, after the girdling mouth grows a better root system, it will be cut off from the mother plant and planted separately in the pot. The disease of kidney bean tree prevents leaf spot disease to be in high temperature, high humidity ventilated bad environment, its leaf is easy infection leaf spot disease. Control methods: Whether indoors or outdoors, ventilation and light transmission should be strengthened to avoid long-term water stagnation on leaves and reduce the possibility of leaf spot disease.
