The leaves of fortune tree turn yellow, wither and love h2>
Fortune tree is loved by the majority of flower friends because of its auspicious meaning. However, it will lose its leaves in autumn, which gives flower friends a headache. Pay attention to these points to ensure that your fortune tree branches and leaves are lush p>
1 watering
Watering too much and too often is one of the reasons why the rich tree leaves p>
Fortune tree is a plant afraid of cold. When autumn comes and the weather turns cold, we must control the dry humidity of the soil. If the soil in the basin is not dry, we don't need to pour too much water. Once too much water is poured, there is water in the basin, and the roots can't absorb nutrients, the new leaves will turn yellow, and the old leaves will wither over time p>
As long as there is a correct watering method, this problem can be avoided p>
At ordinary times, pay attention to the watering frequency. For fortune trees maintained indoors, water them 1-2 times a month. Insert your fingers into the soil. If you feel the soil is dry, you can water it. If it is wet, you don't need to water it. At the same time, pay attention to loosen the soil to ensure good ventilation of the soil p>
2 rotten roots
Rich leaves turn yellow and wither. Another possibility is rotten roots p>
Watering too much, or the soil is hardened and airtight, resulting in poor air circulation, will lead to the rotten roots of the rich tree p>
If the root becomes soft and black, take off the basin, cut off the rotten roots, soak the rest of the roots in potassium permanganate solution for disinfection, dry them and then put them in the basin again p>
3 fertilization
Improper fertilization will also cause rich leaves to turn yellow and fall p>
The nutrients absorbed by the fortune tree are quantitative. If too much fertilizer is applied, after the plant absorbs sufficient nutrients, the remaining fertilizer will burn the roots of the fortune tree, resulting in yellow leaves p>
Normal fertilization can make the fortune tree grow healthily p>
The fertilization cycle is controlled at about 20 days, which is not that the more fertilization, the healthier the growth of fortune tree. In case of yellow leaf phenomenon, it is necessary to appropriately reduce the number of fertilization and replace the soil. Small fortune trees can use peat soil or rotten leaf soil. Large fortune trees are generally mixed with garden soil and rotten leaf soil, because rotten leaf soil is not easy to hold large fortune trees, and it is more difficult to fall after mixing with garden soil p>
4 light
Fortune tree is a sun loving plant. If it lacks light and ventilation, its leaves will turn yellow and wither p>
Place the fortune tree in a place with sufficient light and ensure air circulation. However, it should be noted that it cannot be exposed to the sun for a long time. On a sunny noon, it will be exposed to the sun for 1-2 hours, and then slowly extend the time. The fortune tree will grow particularly prosperous p>
5 temperature
The best growth temperature of fortune tree is 20-30 ℃. Too high or too low temperature is not conducive to its growth p>
If the ambient temperature is too high and the water evaporates, the leaves will dry and turn yellow; Too low temperature can even lead to the death of fortune trees p>
If the temperature is too high in summer, the fortune tree can be transferred to the shade and watered to reduce the temperature. In winter, protective measures should be taken to improve the ambient temperature and prevent the fortune tree from frostbite and death p>
6 diseases and insect pests
Diseases and insect pests are a major reason for the yellow and withered leaves of fortune p>
Fortune trees are vulnerable to fungi and bacteria, causing leaf spot disease. In addition, there are red spiders, scale insects and other pests, "coveting" the health of fortune trees p>
For different diseases and insect pests, we should choose the corresponding medicine, spray it in time and apply the medicine to the case. Spray once every 5 ~ 7 days, and spray 3 ~ 4 times, which is basically good p>
What about the rotten leaves, heart and roots of Clivia h2>
Clivia is as beautiful and dignified as its name. Flower farmers also like to raise it. However, because of the habit characteristics of Clivia, it is easy to have the problem of rotten leaves, roots and heart in the process of growth, which is also a headache. Huahua will teach you a few tricks to make your Clivia no longer "hypocritical" p>
1 rotten leaf
Clivia is a fleshy root with poor water absorption. If you water too much or get wet in the rain, the leaves are easy to rot, so you must pay attention to it when watering p>
Pour it on the pot soil along the four walls of the flowerpot. Don't pour it on the leaves, let alone on the leaf center. Water it according to the principle of half dry and half wet. Don't wait for the soil to be dry before watering, and don't completely water it. It's best to mix some liquid fertilizer in the water, which is more conducive to the growth of Clivia p>
In case of rotten leaves of Clivia, cut off the rotten leaves immediately, put them in a place with light and ventilation, sprinkle a layer of plant ash on the rotten wound, dry it slightly, let the ash particles completely attach to the mucus at the wound, and then plant them in a basin again. It should be noted that during the planting process, all roots should be buried in the sand, and the root neck and wound parts should be completely exposed p>
2 rotten heart
When the weather is muggy and the ventilation is not smooth, it will lead to the rotten heart of Clivia p>
If the central part is rotten, the Clivia can be transferred to a cool place to dry the basin soil. First clean the knife edge, and then cut off the rotten part. Do not spray water on the leaves within 1-2 months to ensure that the leaf surface is clean p>
If the stem base of multiple leaf core clumps decays, take the plant out of the flowerpot, clean the old soil of the root, and completely cut off the decaying part p>
Use cotton balls soaked in 75% alcohol to disinfect around the wound, or smear the wound with earth charcoal powder for anti-inflammatory p>
Then put it in a cool place to dry, and then put it back into the pot with plain soil. The pot soil should be kept slightly wet, but not too wet to prevent the root rot of Clivia p>
3 rotten roots
1 cut off the rotten roots of Clivia, and soak the rest in potassium permanganate solution for 2-3 hours p>
2. Dry it in a ventilated place indoors and apply plant ash or soot on the wound p>
3. Insert Clivia into coarse river sand for planting. Pay attention to it in the process of planting. It should not be too deep into the soil p>
4 put it in a cool place for cultivation. After watering, it is not necessary to water again for a week until the soil surface turns white p>
Autumn has come. Remember these moves Huahua told you. No matter how "pretentious" Clivia is, it can grow luxuriantly, and the fortune tree will grow healthily, bringing good luck to everyone p>
