Why are the leaves of my fortune tree yellow?

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.

The reasons for the yellow leaves of the fortune tree are: improper watering, improper light, and too much fertilizer.

Reason 1: Improper watering

Fortune trees prefer warm and humid climates, and too much or too little watering will cause the leaves to turn yellow.

Overwatering, the soil in the pot is often kept too wet, the roots of the fortune tree do not breathe well, the rhizome rots, and then gradually affects the branches, and finally the leaves turn yellow, wither and fall off, and the whole plant dies in severe cases. If there is too little watering, the potting soil will be moist at the top and dry at the bottom, which will not only affect the absorption of nutrients, but also cause the leaves to be dull and dull, and gradually wither and fall off from the bottom to the top.

Solution: Ventilate, turn the pot or rehydrate in time.

Reason 2: Improper lighting

Fortune trees like sunlight, but they are not tolerant of direct sunlight, and scorching sun exposure or long-term shade will also cause yellowing of leaves.

Placing the fortune tree in the corner of the indoor wall, paying too much attention to the ornamental effect, resulting in the long-term shady environment of the fortune tree, will cause the new branches and leaves to grow yellow, and the old leaves are dull and fall off in large quantities. In the scorching summer, you can only blow the air conditioner in the house, and how can the fortune tree withstand the impact of the scorching sun. If you forget to move it to a shady place around noon, you can only accept the yellowing of the leaves.

Workaround: Move to a semi-shaded area.

Reason 3: Too much fertilizer

The nutrients absorbed by the Fortune Tree are quantitative, and if too much fertilizer is applied, after the plant has absorbed enough nutrients, the remaining fertilizer will burn the rhizome of the Fortune Tree, resulting in yellowing of the leaves.

Solution: Root trimming and soil replacement.

Your flowers are right for yourself.

One is water yellow: caused by excessive watering, it is characterized by no obvious change in the old leaves and yellow young leaves, which should be controlled immediately.

The second is drought yellow: due to lack of water, caused by drought, it is characterized by the first yellow leaves from the bottom up, if the lack of water for a little longer, the whole plant yellow leaves, and even death, should be watered in time.

the third is fat yellow: caused by too frequent fertilization or too high concentration; It is characterized by thick, shiny, and uneven young leaves; Fertilizer, cultivation and watering should be controlled.

Fourth, hungry yellow: caused by insufficient fertilizer, low fertilizer concentration, and long fertilization interval; It is characterized by the first yellow of young leaves and young stems, and if you do not fertilize in time after seeing this phenomenon, it will also cause the whole plant yellow leaves or even die; For flowers lacking fertilizer, avoid applying a large amount of thick fertilizer at one time, so as not to cause root burning.

Fifth, iron deficiency yellow leaves. Due to the great change of soil fertility conditions, the phenomenon of yellow leaves often occurs in greenhouses, which is characterized by obvious young leaves, light old leaves, yellow mesophyll, green leaf veins, and the formation of a typical network. It can be solved by applying ferrous sulfate aqueous solution, and the method is: 7 parts of cake fertilizer, 5 parts of ferrous sulfate, and 200 parts of water are prepared into multiple liquid water.

When the water is large, the fortune tree should be watered less.

There are parasites in Shili, put some Leguo medicine, dichlorvos, and less chloride.

The leaves of the fortune tree raised indoors suddenly turned yellow, mainly due to insufficient light, excessive watering, hard potting soil, poor air circulation, insufficient nutrients in the pot and other reasons.

One: The potted fortune tree is placed indoors in a sunny position, which is conducive to photosynthesis and reduces the symptoms of yellow leaves. Move outside for 2-3 days a week, and the sun is better in the morning and evening for 1-2 hours a day.

Two: usually placed in the indoor sunny and ventilated place, good ventilation is not easy to cause pests and diseases, so that the leaves will not be destroyed and yellowed.

Three: usually watering is not easy to be too wet, too wet is easy to cause root rot, produce yellow leaves die, it is best to do dry watering is not easy to cause the symptoms of rotten roots.

Four: about 2-3 months to loosen the soil, so that the potting soil is loose, breathable and drainage, which is conducive to the growth of the root system and is not easy to appear yellow leaves.

Five: at least twice a year to apply fertilizer, 4-5 months, 8-9 months each apply a compound fertilizer, according to the amount of instructions, in order to prevent fertilizer damage caused by excessive fertilizer, fertilizer can be equipped with some mineral additives and other fertilizers.

Six: change the pot once a year, you can change the pot after winter or next spring, the main thing is to increase the nutrients in the pot, and you can bury some long-lasting base fertilizer at the bottom when changing the pot.

I looked at the big picture, not like a pest. Also available.

Excluding light and temperature, it looks like rotten roots.

If your fortune tree is planted together with multiple trees, it is likely that the roots of the yellowed branch have rotted, pulled out and thrown away!! Because I can't see how many they are, I'm not sure.

If the whole plant is generally yellow, I think it is a problem with fertilizer, and nitrogen fertilizer can still be used this season. Get some nitrogen fertilizer and follow the instructions. Get some phosphorus and potassium fertilizer and spray the foliage according to the instructions.

Most of it has something to do with the lack of light. If the leaves are yellowed as a whole, and the water on the leaves is still sufficient when they turn yellow, it means that they are overwatered or the temperature is low. If it's just the leaf tips turning yellow and a little brown, it's too little watering.

Although the fortune tree likes shade, it still needs a little sunshine. Put it in a place with scattered light, warmth, and ventilation...

Environment [The temperature is low, and the temperature difference between day and night is too small. Insufficient light, low accumulation of photosynthetic products] is not suitable for cause, it is recommended to put it back on the balcony and take care of it for a while.

Fortune tree likes fertile and loose, breathable and water-retaining sandy loam soil, likes acidic soil, avoids alkaline soil or clay soil, is more resistant to water and moisture, but also slightly drought tolerant, spotted bamboo is not the soil has poor air permeability, suffocation.

Moreover, the fortune tree likes high temperature, humidity and sunlight, and cannot be shaded for a long time, so it is recommended to bask in the sun quickly.

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.
