Why are the leaves of my family s fortune tree yellow?

If you compare, the phenomenon of the Fortune Tree showing yellow leaves and falling off is mainly because:

1.Improper watering, fortune tree nature like warm and humid climate environment, potting soil is suitable for moist, but indoor cultivation is generally not dry and watering, watering is watered thoroughly.

2.The light is not suitable, the fortune tree likes light, does not tolerate strong direct light, and is suitable for semi-shade or scattered light, but it needs better light conditions in winter to grow well. If you are in a shaded place or a dark place for a long time, there will be yellow leaves, defoliation, and death in severe cases.

3.Pests and diseases, such as leaf spot, the symptom is that a small number of spots appear, and then the spots gradually expand and extend to the whole leaf, and fall off, can be controlled with carbendazim wettable powder 800-1000 times. Garlic juice can also be sprayed and sterilized in the home.

The insect pests mainly include red spiders, scale insects that harm the fortune tree, and the red spider is small, with a body length close to or less than 1 mm, which can be controlled by mite, mite, dicofol, etc. Individual scale insects vary from species to species, and their colors vary greatly, but they have a common characteristic, that is, they are round or oval, generally do not move, and suck sap close to the stem or petiole of the plant. In many cases, it can be sprayed with the solution of air oil essence and washing powder for prevention and control, and it can also be sprayed with special killers, and the effect is ideal.

If you water too much, the roots will be damaged, and the leaves will turn yellow, so be sure to wait for the soil to dry before watering.

The leaves of your fortune tree are yellow, please compare the following maintenance and management of the fortune tree in winter- The fortune tree is native to Central and South America, prefers warm, moist, sunny or slightly shaded environments, and the suitable temperature for growth is 18 30. The temperature in winter should reach more than 5, otherwise it is easy to freeze damage. In the middle of winter, as long as the temperature is above 18 and the sun is sufficient, it can grow as usual.

When the room temperature is lower than 8, damp, dry and not ventilated, the leaves are prone to water-stained patches, which are bronze and fall off. When the temperature is lower than 5, the leaves all fall, the shoots lose water and dry up, and the whole plant dies when it is serious. Generally, they enter the room for wintering in November and leave the room after the "valley rain".

The fortune tree has a strong adaptability to water, and will not cause waterlogging and drought when watered outdoors or indoors for more than 10 days. However, in winter, the potting soil should be avoided from moisture, and it is advisable to be slightly damp, otherwise the leaf tips are easy to dry and scorch, and even the leaves fall off. If the room temperature is around 12, you can water it once a month.

The Fortune Tree grows faster and has a well-developed root system, and is repotted every 2 years in late autumn or early spring. Do not water before changing the pot, and when the potting soil shrinks and separates from the pot wall, take out the plants with soil, remove some of the compacted soil, replace it with fertile cultivation soil, and replant it. In the outdoor all-sunlight environment, the leaf nodes are short, the leaves are wide, the leaf color is dark green, and the stem base is hypertrophied.

For a long time in low light, the branches are thin, the petioles are drooping, and the leaves are pale green. Therefore, after overwintering, it is necessary to adapt to the light process from indoor to outdoor, otherwise, the leaves will undergo sunburn. In mid to late March of the following year, choose a sunny noon, move the pot out of the outdoors and see the sun directly for 1 2 hours, and then gradually extend the light time until full light management.

1.The ambient temperature is low. If the indoor environment temperature of your fortune tree is kept above 15, the temperature is lower than 18 fortune trees will stop growing, fortune trees are native to tropical America, widely distributed in Southeast Asia, like warm and humid environment, the growth temperature is required to be 18-30, not cold-resistant, spring at the end of March of the lunar calendar or the beginning of May of the solar calendar out of the room, do not lower than 8 room temperature, otherwise frost damage will occur, the light one will fall leaves, and the heavy one will die.

2.Lack of light. Fortune tree likes light but avoid direct sunlight, placed in the indoor scattered light place to raise, winter is placed in the indoor light is better, from the end of April, choose a sunny and warm noon, move the pot out of the outdoor or balcony, directly see the sun for 1-2 hours, gradually extend the time, until the full light management, in the outdoor full light environment, the leaf nodes are short, the leaves are wide, the color is dark green, the crown is plump, the stem base is hypertrophied, and the branches are thin in low light for a long time, the petioles are drooping, and the leaves are light green.

No matter what the environment is raised, the place should not be changed suddenly, and there should be a gradual adaptation process to change the position, such as suddenly transferring the plant from the shade to the sunny place, which will burn the leaves, scorch the edges, and affect the appearance. Long-term lack of light will cause the plant to have yellow leaves and fall off.

3. Lack of water, lack of water leads to yellow leaves.

4.The moisture is too wet. The Fortune Tree does not have high requirements for water, and it should not be watered too much to prevent the potting soil from accumulating water, causing root rot and causing plant death.

Watering once a day indoors in summer, watering once every 5-10 days in spring and autumn, but not an absolute interval, should be flexibly mastered, and should be based on the principle of "seeing dry and wet" in potting soil. Excessive moisture will cause waterlogging, yellow leaves, root rot and falling off of the plant.

5.Too much fertilizer. Rapid growth in the growth temperature period, should be fertilized regularly to ensure that the plant grows luxuriantly, generally about 20 days to apply a thin fertilizer, but to apply less nitrogen fertilizer, to avoid plant growth.

When changing pots, in addition to replacing new nutrient soil, you should also add well-rotted base fertilizer to make it thrive. If too much fertilizer is applied, or if the fertilizer is not ripe, it will burn the roots, yellow leaves and fall off.

You belong to improper maintenance, look at the ** on your yellowing leaves belong to dry yellow, you pay attention to watering in the maintenance Now you can water once every 4-5 days, watering once in 2-3 days in summer, ferrous sulfate in the first half of the month, ammonium sulfate (nitrogen fertilizer) in the second half of the month, so that the leaves will be green and shiny.
