What happens when yellow orchids grow new leaves and rust dry edges?

The new leaves of orchids turn yellow as soon as they grow, and not just because of soft rot.

Orchid leaves turn yellow and fallMost of the reasons are improper watering, improper light, unreasonable fertilization, and metabolismand other reasons.

Causes and solutions for yellowing and defoliation of orchid leaves:

1. Improper watering

There are also two types of improper watering. One is water shortage, and the other is stagnant water. Orchids prefer a moist growing environment, so if there is a lack of water for a long time, or if the humidity of the surrounding air is low, yellow leaves will appear.

At this time, it is necessary to water the orchid in moderation, and once the orchid soil is found to be dry, it needs to be watered in time.

In addition, the air is drier in summer, so you can put a pot of water next to the plant to increase the humidity of the air.

If there is too much water at the bottom of the orchid pot, it will affect the flow of oxygen. If there is a lack of oxygen, the orchid root system will not be able to absorb the required nutrients normally, so it will cause the leaves to turn yellow and dry and so on.

If the orchid has many yellow leaves and leaves, you can loosen the soil to promote water volatilization, and if there is a lot of leaf loss, you can take the orchid out of the pot, cut off the root system that has been damaged by the water blister, and then transplant it into the new soil.

Second, the light is uncomfortable

Under normal circumstances, orchids should be placed under scattered light, and the appropriate amount of sunlight should be received, so that the leaves can be kept in a relatively healthy state, and attention should be paid to ventilation and placed in a cool place.

3. Improper fertilization4. Metabolism

If the orchid is to grow normally, then its plants must also grow. When new leaves grow, the old leaves will slowly turn yellow and wither and fall off, but this is also a very metabolic process, so there is no need to worry too much.

The yellowing of orchid leaves can be caused by too much light.

At this time, you should first use scissors to cut off the yellowed leaves on the plant, and then move it to a place where there is no bright light. It can also be caused by too low a temperature. At this point, move it to a place where the temperature is between 18 and 25 and wait for it to recover.

It can also be caused by a lack of moisture. At this time, it is necessary to water once to water the flower soil completely, and then increase the frequency of watering appropriately to replenish its moisture.

First, the light is too strong.

1. Reason: Except for a few varieties such as orchids, most orchids do not like strong light. If they are raised in a place with high light intensity, their leaves will be sunburned and turn yellow by strong light.

2. Treatment method: At this time, the leaves that are completely yellowed on the plant should be cut off with scissors. Then, move it to a well-ventilated area without bright light, or use a blackout net to shade it. After waiting for a while, it can be restored.

Second, the temperature is too low.

1. Reason: Orchids like warmth and are not particularly cold-tolerant. If the plant is kept in a particularly cold place for a long time, it will cause it to grow poorly and its leaves will turn yellow.

2. Treatment: First move the orchid to a place with a temperature between 18-25, and then appropriately increase the time it receives light, and wait for it to recover.

3. Lack of moisture.

1. Reason: If you do not water the orchid for a long time when you care for it, it will also cause its leaves to turn yellow.

2. Treatment method: At this time, it should be watered in time. Water thoroughly once first, and water the soil thoroughly, but don't let the soil become waterlogged.

Then increase the frequency of watering to replenish it. If nutrients are lacking, you can also appropriately apply water-soluble fertilizer to fertile leaves, and pay attention to the dilution factor.

Analysis and treatment methods of the causes of yellowing of orchid leaves:

1. Excessive watering leads to yellowing of orchid leaves (water yellow): This is a situation with a high probability of occurring, because watering is not measured, and it is believed that the more watering, the better the orchid grows, resulting in waterlogging at the roots, and then making the leaves yellow.

Solution: So we have to water thoroughly according to the watering requirements.

2. Exposure to the sun causes the yellowing of orchid leaves (burning yellow): Vegetation with large leaves like orchids is very afraid of strong light exposure, which will damage the leaf tissue cells, and the leaves will turn yellow.

Solution: So it's best to put it in a place with low light.

3. Dry air causes yellowing of orchid leaves: Dry yellow, due to long-term lack of watering or dehydration, although the new leaves are normal in color, the lower leaves gradually dry and yellow and fall off and age.

Solution: Watering appropriately, always observe the weather conditions, and do water with the weather.

4. Excessive fertilization of orchid leaves leads to yellowing of leaves (fat yellow): Excessive fertilization is commonly known as "burning" seedlings, which is extremely unfavorable to the growth of orchids and can easily lead to the death of orchids, so the more fertilization, the better.

Solution: This should be fertilized in the right amount and applied in the right amount.

5. Long-term lack of fertilizer in orchid leaves leads to yellowing of leaves (lack of fertilizer yellow): Nitrogen fertilizer has a good effect on supplementing the chlorophyll of leaves, and if orchids lack nitrogen fertilizer, it will also cause yellowing of leaves.

Solution: Nitrogen fertilizer can be applied appropriately.

6. Pests and diseases cause yellowing of orchid leaves: In this case, it is necessary to carefully observe the leaves of the yellowed part to see if there are insects eating or ulcerating.

Solution: If there is, there is a pest or disease that needs to be treated.

There are four reasons why orchid leaves turn yellow and fall off:One is that the soil is not suitableThe soil used is clayey or contains insufficient nutrients, and it is easy to have yellow leaves and dry leaves for a long time. Change the soil as soon as possible.

The second is the lack of moisture, it prefers moist environments and is not drought tolerant. If you don't water for a long time, there will be a dry yellow situation, so replenish water and spray water as soon as possible. The third is that the light is too strong, need to be blacked out as soon as possible and moved to a cool and ventilated place.

Fourth, it is infected with pests and diseasesIn severe cases, medication is required.

Soil discomfort:The growth of orchids is very demanding on the soil. If the soil used during the cultivation period is too viscous or the nutrients contained are insufficient, the root system will not breathe well in such an environment, and will not be able to absorb nutrients and water, and the leaves will be prone to yellowing and drying up after a long time.

It is advisable to change the soil as soon as possible to ensure that the soil used is soft, breathable and rich in humus, so that the soil can grow vigorously.

Lack of moisture:Orchids like to grow in a humid environment, if you forget to water for a period of time, the soil is dry and water-deficient, it is prone to drought and yellow. It is necessary to water it as soon as possible and move the orchid to a well-ventilated environment.

In addition, it is important to pay attention not only to the moisture of the soil, but also to the humidity, which needs to be sprayed regularly when the climate is dry.

The light is too strong:Orchids are semi-negative plants that are afraid of strong light and direct light. If it is left in an environment with direct light for a long time during the maintenance period, it is easy to get sunburned, and the leaves will dry up and turn yellow.

In this case, it is necessary to shade the sun as soon as possible, move to a cool place, and spray water frequently to promote a quick recovery.

Infected with pests and diseases:The yellowing and drying of the leaves of the orchid may also be due to the unsuitable environment and the infection of pests and diseases, which leads to the recommendation to cut off the diseased part and spray the sterilization and disinfection drugs. If there is an insect infestation, kill it as soon as possible, and after treatment, maintain it in a ventilated place, and it will slowly resume growth.

Causes of yellowing and solutions:

1. Water yellow. Caused by over-frequent watering, it is characterized by no obvious change in old leaves and yellowing of young leaves; Water should be controlled immediately.

Second, dry yellow. Due to lack of water, caused by drought, it is characterized by the old leaves from the bottom to the top of the first yellow, if the lack of water for a little longer, the whole plant yellow leaves, or even death, should be watered in time. 3. Fat yellow.

Caused by excessive fertilization or high concentration, the extra round brother point is that the young leaves are hypertrophied, shiny, orange cracked and uneven; Fertilizer, cultivation and watering should be controlled.

Fourth, hungry yellow. If the source is caused by insufficient fertilizer, low fertilization concentration, and the fertilization interval is too long, it is characterized by young leaves, young stems are yellow first, if this phenomenon is not fertilized in time, 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.

How to deal with the yellow leaves of orchids, orchids as one of the top ten famous flowers in China, is one of the flowers that many flower friends chase and plant, in fact, it is not difficult to plant good orchids, it is not so easy to say easy, only the yellow leaves of orchids can stump many people, and I share how to deal with the yellow leaves of orchids!

The yellowing of the leaves of orchids is often caused by improper watering or excessive sunlight exposure to sunlight. On the one hand, it is necessary to prune off the yellowing leaves that cannot be saved as soon as possible, and on the other hand, it is necessary to adjust the amount of water and improve the light intensity. If the yellow leaves are caused by rhizome problems, the roots should be repaired in time and the soil should be replaced.

1. Prune the leaves

If the orchid has yellow leaves, the situation is relatively light, you can leave it on the branch first, and slowly restore its greenness according to the follow-up maintenance techniques. The yellow leaves are more serious, and if they are dry, wilted, drooping, etc., they should be pruned with a clean and sharp pruning knife, and all the petioles should be pruned down and burned in a concentrated manner.

2. Adjust the humidity

Water quantity and humidity are one of the main factors causing the yellowing of orchid leaves, and excessive watering will cause yellowing, which is manifested as wet leaves and become wilted. Too little watering will cause a dry yellow condition, which is manifested as dry and fragile leaves, which will break when touched. Adjust the humidity in the potting soil according to the specific situation.

3. Control the lighting

When the leaves of orchids are exposed to strong direct sunlight, the leaves will be sunburned, and a large number of sunspots will appear on the leaves, and they will become wilted and yellow, and there is no growth activity. After pruning the leaves, move the orchid to a ventilated one. In the environment, accept direct light of moderate intensity, or use scattered light instead.

4. Trim the roots and change the pot

There is no problem with the maintenance of light, water, etc., and if the orchid is still yellow leaves, it is necessary to check whether the cause is on the rhizome. If the rhizome is broken or rotten, the orchid cannot properly divert nutrients, and it is easy to yellow the leaves. Remove the orchids from the old potting soil, prune the rhizomes, disinfect and sterilize, and replant them into the new potting soil.

First, the light is too strong

1. Reason: Compared to an environment with sufficient light, orchids are more suitable for growing in a semi-shaded environment. If the bulge is firm, it may sunburn it and give it a yellow leaf.

2. Treatment method: Move the sun-dried plants to a semi-cool place and keep them ventilated. Then cut the scissors from the yellow leaf and wait for it to grow new leaves.

2. Overwatering

1. Reason: Orchids are fragile and cannot grow normally in the substrate in the case of stagnant water. If overwatering during maintenance allows water to accumulate in the substrate, it may soak the roots and yellow leaves.

2. Treatment: First take out the plants from the original pots, and then cut off all the rotten yellow leaves with scissors. It is then planted in new soil without standing water, pausing watering for a while and waiting for it to recover.

Third, the fertilizer is too thick

1. Reason: It likes chemical fertilizers, but it does not like thick chemical fertilizers, because thick chemical fertilizers may burn its root system. If the concentration of flower fertilizer applied during the curing process is too high, it may damage its root system and cause its leaves to turn yellow.

2. Treatment method: first rinse the remaining flower fertilizer in the soil with water, then place it in a ventilated place to dry the soil, then temporarily stop fertilizing for a period of time, and then wait for recovery.

The dry tip of the orchid leaf may be due to the lack of water in the plant, rotten roots, too low ambient temperature and too strong light, there are many reasons, first cut off the dry part, find out the reason, and then correct.

Dividing can be carried out in both spring and autumn, generally once every three years. All plants with strong growth and dense false corms can be divided, and at least 5 connected false corms should be kept in each cluster after dividing.

Irrigation should be reduced before dividing the plants to make the potting soil drier. When potting after dividing, first cover the hole at the bottom of the pot with broken tiles, then lay coarse stones, accounting for 1 5-1 4 depth of the pot, then put coarse soil and a small amount of fine soil, and then plant with sandy loam soil rich in humus. The planting depth is to bury the false bulb in the soil, leave 2cm along the edge of the pot, spread the green cloud grass or fine stones, and finally water thoroughly, put it in the shade for 10-15 days, keep the soil moist, gradually reduce watering, and carry out normal maintenance.

Answer: Hello, there may be three reasons for the yellowing and drying of orchid leaf tips: 1. Environmental mutation causes orchid leaves to turn yellow: environmental mutation includes environmental changes when turning the table, turning over is very good for orchids, but if it is not turned properly, it will cause orchids to not adapt, resulting in temporary yellowing of leaf tips.

Solution: At this time, it is best to repot and make sure that the orchid root system is intact. 2. Long-term lack of water leads to yellowing of orchid leaves (dry yellow):

Caused by lack of water and drought, it is characterized by the first yellow leaf tip of the old leaves from the bottom up, and if the lack of water is a little longer, the whole plant will be yellow and even die. Solution: It should be watered in time, but not too much at one time, first water a small amount of water, and gradually increase the amount of water.

3. Yellowing of orchid leaves due to air drying: Orchid leaf tips turn yellow, and the new shoots are smaller, which may also be caused by dry air. Workaround:

Orchids prefer a ventilated environment, and it is best to transplant them in a well-ventilated place.
