What's wrong with the yellowing of keel leaves? too much watering, excessive fertilization / light is the key.

Dragon bone flower, also known as the measuring ruler, it is a plant type fitness, has a good ornamental, but also can bear dragon fruit plants. In life, raise dragon bone flower person is very much, can raise raise, many people can encounter the symptom of leaf yellow, that dragon bone flower leaf yellow is how? In this regard, Xiaobian summarized the reasons for the yellowing of six keel leaves, and went to understand them together.

1. Yellow leaves of keel flower, find out the cause

Dragonflower is rare indoors, and has only been known in recent years, so there are many novices who raise it. This situation also caused many flower friends not to know the cultivation method of dragon bone flower. As a result, yellow leaves appeared when they were raised. What happened to yellow leaves of dragon bone flower? To this, flower friends can not be anxious, but need to calm down to find the cause, and then solve. How to do it, let's see below.

2. Causes and solutions of yellowing of keel leaves

1. Environmental mutation

There are many reasons for the yellowing of dragon leaves, but environmental factors are the first thing to consider. The reason for this is that nowadays everyone's dragon bone flowers are purchased online, which is easy to cause a large geographical span, dragon bone flowers can not adapt for a while, resulting in yellow leaf symptoms.

Solution: Communicate with the store in time to understand the growth environment before buying keel flowers, and then we change to the same environment at home. Then slowly change until fully adapted to the current environment, after a period of time, the plant will return to health.

2, improper lighting

Light is an indispensable part of the growth process of keel flowers, but it is also the main factor causing yellow leaves. There are two kinds of improper illumination: one is too strong illumination, and the other is insufficient illumination.

① too strong light: dragon flower avoid strong light, once the light is too strong, it is easy to damage the leaves, resulting in yellow leaves. Solution: Move the flowerpot to a ventilated astigmatism, and pour the right amount of water, which can be restored after a while.

② Insufficient light: keel flower likes the environment with weak light, but it grows without light. Once the light is insufficient, the leaves lack photosynthesis. For a long time, the symptoms of yellow leaves will also appear. Solution: Move the flowerpot to a place where there is light. If the light is strong, you need to shade it properly.

3. Too much watering

Watering is the key to cultivating keel flowers, but once watered too much, it is easy to cause yellowing of keel leaves. Because too much watering will cause ponding in the basin, affecting the nutrient absorption of the root system, the root rot phenomenon, so there will be yellow leaves.

Solution: immediately stop watering, and move it to the ventilated astigmatism, let the water evaporate quickly; serious, pull out the keel flower, replace with fresh culture soil, and then replant.

4. Excessive fertilization

After watering, let's talk about fertilization. In the process of life, although the keel flower needs less fertilizer, proper fertilization can make it grow better, but once the fertilizer is excessive, or the frequency of fertilization is too fast, it may lead to yellowing of the keel flower leaves.

Solution: immediately water keel flowers, dilute fertilizer, and let excess fertilizer from the pot loss; serious when the same, replace the pot soil to save.

5. Diseases and pests

In addition to the above points, we should also consider the impact of pests. Therefore, once it is entangled by pests, the leaves of keel flowers will also appear yellow symptoms. At this point, we only need to find the cause, and according to the dragon flower pest control to do it.

6, normal conditions

If the reason for the yellowing of the keel leaves can rule out the above, then everyone has to consider whether this is a normal physiological process. It is understood that keel flowers will be accompanied by yellow leaves and other phenomena when falling leaves, which belongs to a very normal phenomenon, at this time we do not have to be nervous, just need to remove the yellow leaves can be.

In general, dragon flower is not difficult to raise, but because many flower friends are novices, it is inevitable that there will be symptoms of yellow leaves. However, after reading the full text, I believe everyone has a bottom in mind, and the problem of leaf yellow appears according to the above method. With regard to the yellowing of keel leaves, Xiaobian introduced this, hoping to bring help to everyone.

How does the yellow leaf of the dragon flower cause the yellow leaf?

Dragon bone flower is a common family flower, indoor culture is conducive to purifying the air. In addition. The keel column has the name of "universal rootstock", so what about the yellowing of keel leaves?

1. What should I do if the dragon bone flower leaves are yellow?

1, the deciduous period causes the keel leaves to yellow: if it is in the deciduous period, then the leaves turn yellow is a natural thing.

Solution: Clean up the yellow leaves.

2, too much watering leads to yellow keel leaves (water yellow): too much watering will lead to root rot, leaves turn yellow.

Solution: Stop watering. The keel flower can survive even if it is watered only once in 1-2 months when it is dormant in winter. Spring can be separated by 10 or half a month to irrigate water, and with daily water spray. Water once a day in the morning or evening in summer.

3, long-term water shortage leads to yellow leaves of keel flower (drought yellow): leaves are prone to yellow phenomenon under strong light.

Solution: Shade measures should be taken in summer and placed in a place where light can be seen in winter to receive a certain amount of sunlight. Indoor plants had better be placed on the balcony, windowsill and other places where light can be seen.

4. Too much fertilization of keel flowers leads to yellowing of leaves (fat yellow): too thick fertilizer is easy to cause fertilizer damage and root rot problem

Solution: keel flower in the growth period can be applied every 15-20 days a thin fertilizer, such as granular compound fertilizer or self-made alum fertilizer, can promote plant growth.

5. Diseases and insect pests cause the leaves of keel flowers to yellow: they will die when they are ill.

Solution: You can use carbendazim, poured on the roots of plants.

Second, keel flower maintenance experience

1, cultivation soil: keel flowers like loose, fertile, rich in humus soil. Potting soil can be mixed with 1 part of rotten leaf soil and 1 part of coarse sand and added with a small amount of decomposed chicken manure or cow dung.

2, light and temperature: summer should be placed in semi-shady environmental conditions maintenance. Winter requires sufficient light, placed in the indoor sunny place, the temperature should be kept above 10℃, the temperature is less than 10℃ easy to occur freezing damage.

3, water and fertilizer: spring watering should not be too much, every 10-15 days to water once, but every day should be sprayed to the plant, increase air humidity. Water should be watered once a day in summer, preferably in the morning or evening. Winter basin soil should be kept moderately dry, available plastic film wrap basin protection winter. The overwintering cultivation environment should keep both high temperature and high air humidity.

Note: In order to prevent premature aging of keel plants and maintain the vitality of its base, attention should also be paid to pruning frequently. Cut off some old branches that do not bloom much, and remove the weak buds growing below, so that the terminal buds fully develop, elongate and bloom more.

What about yellow leaves?

normal factor

Dragon bone flower will cause its leaves to yellow because of a variety of factors, first of all, dragon bone flower will appear when the leaves yellow phenomenon, usually during the deciduous period of dragon bone flower, then the leaves yellow is a relatively normal phenomenon, we only need to remove the yellow leaves can be.

too much watering

The second phenomenon may be caused by more watering of keel flowers. If we water too much, the roots of keel flowers will accumulate water, which will affect the nutrient absorption of roots and cause the phenomenon of root rot, so that yellow leaves will appear. Once this happens, you need to stop watering immediately. The keel flower will enter dormancy in winter, when it is not suitable for too much water, and it can be watered once or twice a month. In spring, half a month for a thorough watering can be. Summer evaporation is relatively large, every day in the morning and evening time period need to be watered once, so as to avoid yellow leaf phenomenon.

Irrational lighting

The third reason may be because of the problem of light, the intensity of light will affect the leaf color of keel flower, in summer, the sun is stronger, usually we need to take shading measures to avoid being damaged by strong light. Winter sunshine is weak, then it is necessary to carry out appropriate lighting to promote the better growth of the leaves of keel flowers, generally placed in front of the window or under the balcony growth can be.

excessive fertilization

The fourth reason may be that when the keel flower is managed, too much fertilizer is applied. The fertility requirements of the keel flower can be met with a small amount. Generally, during its vigorous growth period, it can grow healthily once a month.

pest

The last reason is that the leaves of dragon bone flower may be damaged by pests, resulting in this phenomenon. We can irrigate with antibacterial agents, which can effectively prevent and control pests.
