How to give first aid if the leaves of the peace tree are dead

Hurry up and change the soil for a large pot, add nutrient soil and organic fertilizer, and water the second water ten days and a half months after watering.

It is necessary to depot and prune off the rotten root system, disinfect and dry the root system, and finally replant it with new soil. If the soil is alkaline, it is necessary to add new soil appropriately and loosen the soil frequently.

As long as the root system is good, it can still be saved, and it should be carefully cared for.

1. Illumination. Give it an ambient temperature of 10 to 35 and give it plenty of sunlight.

Irradiation, but when the sun is strong, avoid direct sunlight and give it proper shade.

2. Moisture. The air humidity of the surrounding environment is required when the tree is cultivated.

Try to be larger, the potting soil can be slightly dry, do not water too much, and usually spray the leaves of the peace tree frequently to increase the humidity of the air, generally speaking, when the relative humidity of the air.

When it is greater than 80%, it will be able to grow vigorously.

3. Fertilizer. The demand for fertilizer and water is not particularly high, but in the growing season, liquid fertilizer should be added once in almost 10 days, and Bika fluid fertilizer can be selected, which can promote its relatively strong growth. After autumn, phosphorus fertilizer is added 1 or 2 times to improve its cold resistance.

If too much fertilization will cause the leaves to turn yellow and fall off, at this time it is necessary to take out the plant, carefully check whether the root system has rotten roots, if rotten roots occur, it is necessary to cut off the rotten roots, and at the same time cut off a part of the branches and leaves, and replace the soil.

<> the temperature rises to keep warm, it is necessary to move the tree to a warm room, and the maintenance temperature is too low to dry out the leaves of the tree; After the leaves of the disinfected root system are dried up, they need to be taken out of the pot, placed in carbendazim solution for disinfection, and then re-potted; To adjust the soil quality, it is necessary to water the diluted ferrous sulfate solution into the soil to alleviate the soil alkalinization, which will dry up the leaves of the peace tree.

After the leaves of the tree are dry, they should be removed from the pot in time and the roots should be soaked in carbendazim solution for disinfection. The later maintenance needs to strictly control the amount of watering, need to water every 2 3 days, and ensure that the soil is in a slightly moist state when watering, so as to avoid the soil from producing water and making the leaves of the safe tree dry out.

The diluted ferrous sulphate solution needs to be poured into the soil to make it slightly acidic. The tree is suitable for growing in slightly acidic soil, if the soil socks are too alkaline or planted with alkaline soil, the leaves of the tree will fall.

After the leaves of the tree fall off, it is necessary to transfer it to a warm room for maintenance in time, and control the room temperature above 10. The cold tolerance of the peace tree is poor, and if you do not take warm measures in winter, the leaves will be frostbitten and turn yellow and fall.

If the fall of the leaves of the safe tree is more serious, it is necessary to prune the yellowed and dry leaves in time for centralized destruction, and then evenly spray the diluted zinc-manganese solution on the leaves. In the later maintenance of the safe tree, it is necessary to open the window frequently for ventilation to ensure the circulation of indoor air, if it grows in a closed environment for a long time, it will make the leaves of the safe tree yellow and fall. The town is easy to change.

1. Uncomfortable temperature.

In winter, when the temperature is relatively low, if it is not moved indoors in time to keep warm, its leaves may be frostbitten and cause yellowing.

Prevention and control: the temperature in winter shall not be lower than 5 degrees, before cooling down, the peace tree should be moved indoors to keep warm, if it has been frostbitten, then gradually increase the room temperature, and the yellow leaves that have been frostbitten are removed.

2. Discomfort of light.

Strong light and lack of light, strong light exposure will burn the leaves and make them yellow; If there is a lack of light for a long time, the leaves will also turn yellow and even fall into serious cases.

Prevention and control: In summer, it should be shaded, if it has been burned, move it to a semi-shaded bench environment for maintenance, and remove the yellow leaves. In spring, autumn and winter, it is necessary to maintain a relatively long period of light.

3. Improper watering.

The peace tree likes a moist growth environment, but it is not suitable to accumulate water, which will cause rotten roots, so that it can not absorb nutrients from the soil normally, and the leaves of the peace tree will turn yellow if there is a lack of nutrients.

Prevention and control: The safe tree can keep the potting soil slightly damp. If the water is large, you can raise the pot to let the water evaporate quickly, if it has caused root rot, you should take out the whole plant, prune off the rotten roots, and disinfect with carbendazim before replanting.

4. Ventilation problems.

Poor ventilation will cause stuffy roots, and if there are rotten roots, the leaves will also grow rotten and make rotten spots, and finally cause the whole plant to fall off, and the top will wither from top to bottom.

Prevention: Maintain good ventilation, after watering under the condition of ventilation and light, the water on the soil surface can quickly volatilize, the soil is in a wet but not silted state, and its root system is not short of water and then supplement fertilizer growth will be very good.
