How to solve the yellow leaves of geraniums

1. Geraniums.

Geranium, also known as paraffin red and hydrangeas, is native to southern Africa. Geranium has a beautiful and elegant appearance, and it is a popular ornamental plant at present.

2. Causes and solutions for yellowing of geranium leaves.

1. Excessive watering leads to yellowing of geranium leaves: In daily maintenance, many people are worried that the plant will lack water, so they water frequently, resulting in the soil in the pot being too moist for a long time, and if the temperature at this time is very high, it may cause some of the geranium's roots to rot, causing the leaves to turn yellow.

Solution: In daily life, pay attention to control the amount of watering of geraniums, and put the pot in a ventilated and dry place to speed up the evaporation of water, or put the pot on a pile of newspaper or dry peat, so that the newspaper and peat can suck out the excess water in the pot as soon as possible.

2. Geranium leaves are yellowed due to unsuitable temperature: Geraniums like a warm and humid growth environment, and the temperature is too high in summer, which will affect the absorption of iron by the roots, which may cause the phenomenon of iron deficiency in the newly grown leaves.

Solution: When the sun is strong in summer, it is best to put it in a ventilated and cool place, you can also spray and water chelated iron solution, spray once a week, and after spraying 3 times, the leaves will basically return to normal.

3. Geranium leaves are yellowed due to the invasion of pests and diseases: If geraniums are attacked by pests and diseases, it may lead to leaf spot and gray mold, which makes the internal tissues of the leaves problematic and causes the leaves to turn yellow.

Solution: At this time, it is necessary to spray pesticides in time, and you can spray 1000 units of agricultural streptomycin or 1000 times of 50% sterilizer.

4. Improper fertilization leads to yellowing of geranium leaves: Generally speaking, plants need an appropriate amount of fertilization during the growth period to promote plant growth. But if too much or too little fertilizer is applied, it will lead to the opposite result.

Solution: At this time, fertilizer control is required, if there is too much fertilizer, the soil in the pot should be replaced immediately, the roots should be rinsed with water, and the plant should be replanted.

The reason for the yellowing of geranium leaves: the lack of fertilizer causes the yellowing of new leaves, if the fertilizer has not been topdressed for a long time, the plant growth is weak, and the topdressing can be given appropriately. In addition to the lack of fertilizer, there is also a very important reason for excessive humidity, usually the pot used is high and deep pots, the soil is relatively dry, and the bottom of the pot 1 3 is still very wet.

Geranium is a kind of flower that is more difficult in summer, and the leaves are yellowing and affect growth, and the leaves are dry, falling leaves, and the whole plant is dead. The most common problem of geraniums in summer is that the new leaves turn yellow and white, which is thought to be caused by too high temperature, and it will be normal when the temperature drops in autumn. The direct cause of the yellowing and white of the new leaves of geraniums is that the weather is too hot, but waiting is not the way, some can survive the high temperature to usher in autumn, and some die directly in the high temperature.

Therefore, for the yellow and white new leaves of geraniums, it is still necessary to solve the problem, so that Xiaotian can usher in autumn as much as possible.

The main reason is that the weather is too hot and the temperature is too high to affect the synthesis and decomposition of chlorophyll, resulting in a decrease in the chlorophyll content per unit area of the new leaves, thus turning abnormal yellow or white. When the new leaves of geraniums are yellow-green, it means that there is still chlorophyll in the leaves, but the content is relatively small, and the chlorophyll content is not as much as in normal leaves. When the new leaves of the geranium are completely pure white, it means that there is almost no chlorophyll in the leaves, and it cannot maintain normal growth.

Therefore, the whiter the new leaves of geraniums, the more severe the condition, and the more likely the leaves are to dry up and fall off or die as a whole.

The minimum temperature of geranium chlorophyll formation should not be less than two degrees (when the temperature is too low, the chlorophyll synthesis is less, and the leaves will turn red), the maximum temperature should not be higher than forty degrees, and the most suitable temperature for chlorophyll formation is thirty degrees (the temperature here is not an absolute value, it is about this number, and there will be one or two degrees, two or three degrees of variation space before and after). In general, when the temperature is higher than 35 degrees, the new leaves of geraniums may produce less chlorophyll than they decompose, causing changes in leaf color.

In addition to temperature, light, water, oxygen, trace elements, and soil acidity and alkalinity all affect the chlorophyll synthesis of geranium. When the light is insufficient, the watering is too little, the oxygen is insufficient, the trace elements are missing, the soil is acidic or alkaline, the new leaves of geranium are also easy to lose green and turn yellow or white, here we focus on the effect of the lack of trace element iron ions on chlorophyll synthesis.

Normal update. The first time you raise geraniums, you may have little experience, and the small leaves that have just grown, dull in color, are normal, and they can recover after a while. There is also a situation where the plant is growing very well, but the leaves near the potting soil start to yellow and fall off, which is the normal metabolism of the plant.

Don't worry.

Abrupt changes in the environment. When the temperature of many flower friends changes, they move geraniums from the outdoor flower stand to the indoors, or from the south balcony to the north balcony, or from the outdoor to the corridor with full sunshine, etc., in these cases, the maintenance environment suddenly changes the source nucleus, which will cause the old leaves of geraniums to turn yellow and the buds to dry up. As long as the dead leaves are cut off in time, the plant will adapt to it after a while, and it will naturally recover.

High temperature. In summer, the leaves turn yellow, which affects the normal growth of the root system. The main reason is that the environment is hot and stuffy, and the roots and hail trembling digging system cannot absorb nutrients from the soil, resulting in the yellowing of new leaves, and in severe cases, there are dead spots and gradually scorched and fallen off.

This situation is not to be worried, the iron solution can be sprayed and watered appropriately, once a week, and basically recovered after 3 waterings. In addition, with proper cooling and ventilation, the leaves will slowly recover.

Improper watering. Watering too often, or not watering for a long time, can cause the leaves of the plant to turn yellow. With less watering, the potting soil is dry, the geranium leaves turn yellow and fall off from the bottom to the top, and the petioles droop and wilt when severe; Watering a lot, the potting soil is wet, the old leaves have no obvious changes, the young leaves turn pale yellow, and the root system rots and the plant dies when it is serious.

Water in moderation, and if you water too much, place the pot on top of newspaper or peat to suck out the excess water. Or simply depot, dry the plant, and replant.

1) Specific reasons: When the high temperature comes, some flower friends will suddenly move the plants indoors, or from full sunlight to semi-shaded places. These sudden changes in the environment can easily make the plants unable to adapt for a while, and the leaves will turn yellow.

2) Solution: There is no need to worry too much about this situation, the plant itself has an adaptation process. Just make sure that the conditions are right, and the plant will slowly recover.

1) Specific reasons: too many times or amounts of watering, the soil is too wet for a long time, and the root system will rot. Next, the young leaves will turn yellow, and there will be no obvious change in the old leaves.

2) Solution: Immediately control the water. And loosen the potting soil and put it in a ventilated and dry place to speed up the evaporation of water inside.

1) Specific reasons: After the exposure to the sun during the long filial piety bending period, the leaves turn yellow, which is called burning yellow.

2) Solution: Put the plant in a cool place immediately, and it will recover quickly.

1) Specific reasons: Plants have requirements for air humidity, and if the humidity is too low and the air is dry, the leaves will turn yellow.

2) Solution: You can spray or sprinkle some water appropriately, but don't spray too much on the leaves.

1) Specific reasons: the temperature is too high, so that the plant is hindered from absorbing iron, and yellow leaves appear.

2) Solution: It needs to be placed in a cooler place, such as an air-conditioned room.

Some of the common causes of yellowing of geranium leaves are lack of sunlight, unhealthy temperatures, and possibly excessive fertilization. If the leaves of geraniums are yellow due to lack of sunlight, it is necessary to move the plants to a sunny place in time to maintain and increase light. If it is caused by unsuitable temperature, move to a cool place for maintenance if the temperature is too high, and move to a warm place indoors if the temperature is too low.

If it is caused by excessive fertilization, it should be repotted immediately and replanted with soil.

A common cause of yellowing of geranium leaves.

The yellowing of geranium leaves should be caused by improper maintenance, and there are different manifestations, the common manifestations are leaf yellowing and flower buds drying, and there is a yellow leaf symptom that the old leaves on the leaves have no obvious changes, the young leaves turn yellow, and the serious old leaves will also turn yellow and fall off. In general, some of the common causes of yellowing of geranium leaves are lack of sunlight, unsuitable temperature, and possibly excessive fertilization.

Lack of sunlight:If the environment where geraniums are maintained is not sunny enough, the internal leaves of the plant will turn yellow and fall off, and the old leaves will wither after the new branches and leaves germinate.

Temperature discomfort:If the temperature of the environment in which geraniums grow is too high, the roots will not be able to absorb iron, resulting in yellowing of the leaves, and too low a temperature will also cause the leaves to turn yellow.

Excessive fertilization:If you fertilize geraniums too much when you care for them, it will cause the root system to be burned, the root system will rot, and the leaves will turn yellow.

Geranium leaves are treated with yellowing.

1. If the leaves of geraniums are yellow due to lack of sunlight, it is necessary to move the plants to sunny ground in time to maintain and increase light.

2. If the geranium leaves are yellow due to temperature discomfort, move to a cool place for maintenance if the temperature is too high, and move to a warm place indoors if the temperature is too low.

3. If the leaves of geraniums are yellow due to excessive fertilization, they should be repotted immediately, part of the old soil should be removed, rinsed with water, replaced with plain soil without fertilization, and then planted.

Prevents yellowing of geranium leaves.

In order to prevent the yellowing of geranium leaves, in addition to daily proper watering, we should also pay close attention to the growth status of the plant and the situation of pests and diseases, and find and solve it in time, so that geraniums can grow better.

Both high temperatures and poor ventilation can cause geranium yellow leaves, the difference is that hot yellow leaves are usually new leaves yellow, while the lower leaves of poorly ventilated plants are yellow. In the current season, yellow leaves caused by poor ventilation are more common. Recommend that you can:

1. Improve the ventilation condition under the plant, 2. Thin the leaves to enhance the air permeability of the whole geranium. In addition, the yellow leaves are irreversible, so it is advisable to cut them off.

Add a little more, the dry and wet cycle is relatively slow in winter, pay attention to watering not too often, see dry and wet as well. It is particularly important that fertilizers should not be applied when the plants are not in good condition: fertilizer application when the growth is not vigorous enough is easy to cause fertilizer damage.

If the yellow leaf phenomenon disappears, geraniums return to normal growth, and then top dressing with phosphorus and potassium fertilizer.

Thank you upstairs, the first few days I planted it was a rainy day, no sun, these days just began to dry, my balcony sun is not very violent, in short, the leaves are constantly turning yellow, the seedlings are getting smaller and smaller, I don't know if there is a problem with the root system.

Hello friends: Geranium sex likes light sufficiently, but in the summer is not suitable for strong light exposure, watering should not be too much, "rather dry than wet", especially in summer to control fertilization, friends try to see a few days what is the effect?

There are generally two reasons for the yellowing of geranium leaves: one is the yellowing of the leaves caused by sun exposure, and in severe cases, they will die. To control watering, if you water too much, the water cannot be discharged in time, which will also cause the yellowing of geranium leaves.

If there is no obvious change in the old leaves of geraniums, and the young leaves turn yellow, it is often caused by too much watering.
