The reason for the yellow leaves.

Golden diamond is a plant of Araceae, belonging to a kind of angiosperm, native to South America such as Brazil and Paraguay. The golden diamond is a perennial evergreen herbaceous plant. Its stem is almost cute compared to its strong, slender petiole and broad and huge leaves. According to the largest height known to be found, the golden diamond can reach more than 1.5 meters, and it is full of vitality with clusters of dense green leaves.

Golden diamond leaves yellow according to its occurrence characteristics, there are the following situations:

1. Water yellow: the young leaves are dark yellow and dull, the old leaves have no obvious change, the branches are small and yellow-green, and the new shoots are not long, indicating that they are overwatered. Remove the flowers from the pot and place them in a ventilated, cool, self-drying soil mass and then put them back into the basin.

2. Dry yellow: the yellow of lack of water is not the same as that of much water, the yellow of lack of water is withered or dry at the tip or edge of the leaf, and the old leaf is withered and yellow from the bottom up, but the growth of the new leaf is relatively normal. Pay attention to watering enough and thoroughly.

3. Burning yellow: strong sunlight shines directly on some shade-loving flowers (such as orchids, peacocks, taros, hairpins, etc.), which can easily cause withered leaf tips and edges, and yellow spots in the sunny part of the leaves. Just move to the shade.

4. Lack of light and yellow: put in a shady environment for a long time, the leaves can not get enough sunlight, can not form chlorophyll, the whole leaves turn yellow and then fall off, supplementary light can avoid the disease.

5. Fat yellow: flowers yellowing caused by excessive fertilization or excessive concentration, showing dry brown at the tip of new leaves, thick and dull leaves, and concave and convex leaves that do not stretch, and old leaves are scorched yellow. Fertilizer should be stopped immediately and some fertilizers should be washed with a large amount of washing. How to treat the yellowing of golden diamond leaves? prevention and treatment of yellowing of golden diamond leaves

The golden diamond has a good name and looks good. It can be farmed in the office or at home. It can purify the air and make you feel better. But when breed can send cash drill leaf turns yellow, how to do? Today, let's introduce the prevention and treatment of golden diamond leaves yellowing.

The reason for the yellowing of golden diamond leaves

1. The reason of basin soil

Poor selection of soil will affect the growth of golden diamond, when the lack of nitrogen, phosphorus, potassium, magnesium and other trace elements in the soil, it will cause leaves to yellowing.

Nitrogen deficiency in basin soil: the leaves are small, the leaves are yellowish, the lower leaves are yellow first, the whole plant loses green gradually, and the lower part is more yellowish. Phosphorus deficiency in basin soil: the leaves are curly, the leaves are dark green, and the veins of the lower leaves are yellowed.

Potted soil is deficient in potassium: the edge of the lower leaf is brown and easy to lodge.

Magnesium deficiency in basin soil: chlorosis and whitening at the edge and middle of leaves from bottom to top.

Iron deficiency in basin soil: scorched brown spots dried up in the leaves.

2. Improper watering

Too much or too little watering will cause the leaves to turn yellow, but the performance of the two is slightly different.

The golden diamond is overwatered, the young leaves are dark yellow and dull, the branches are small, the new shoots grow slowly, too little watering, the leaf tips and edges wither, the old leaves wither and fall off from top to bottom, but the new leaves grow normally.

3. if the light is not suitable, the golden diamond is a shady plant, and the proper scattered light can grow well, if the light is too strong, the leaves will burn and turn yellow; if placed in a shady place for a long time, without light, the plant will yellowed due to slow growth.

4. Golden Diamond is a foliage plant, which mainly harms the leaves, slows down the growth of the plant, the leaves are dull, and the whole plant dies when it is serious.

Prevention and treatment of yellowing of golden diamond leaves

1. Temperature control and humidification

Golden Diamond likes a warm and humid environment with a temperature of about 20 ℃ and no less than 10 ℃. At the same time, it should be placed to avoid heating, air conditioning and cold air. Indoor humidity should also be relatively increased, controlled between 50% and 70%, less than 50% gold drill is prone to yellow leaf dry edge phenomenon. Air humidity can be increased by spraying and sprinkling water.

2. Shading fertilization

The golden diamond likes the light and avoids the strong direct light, the growth environment had better be maintained under the condition of semi-shade or scattered light, and should not be placed in the shady environment for a long time, otherwise the leaves are very easy to turn yellow. Fertilization should be based on the principle of diligent application of thin fertilizer and mainly nitrogen fertilizer.

3. Proper water control

Watering is best carried out when the surface of the basin soil is dry, and it can be kept moist during the high temperature in summer. If the ambient temperature is lower than 15 ℃ in winter, it needs to be watered alternately.

4. Pest control

The main pests are red spiders, which are generally caused by air dryness, which can be effectively prevented by spraying water frequently and wiping leaves. When there are insect pests, special insecticides need to be sprayed for prevention and control, such as triclofenac and so on. Usually as long as the environment is suitable, what diseases and insect pests will disappear!

What if the golden diamond leaves turn yellow? Causes of yellowing of golden diamond leaves and its solutions

The golden diamond can also be called the golden diamond vine green velvet, which has the nickname of the evil king. The reason why it is called the evil king is mainly because the golden diamond belongs to shady plants and has the function of purifying the air in order to absorb all kinds of poisonous gas nutrients. It is one of the more popular indoor ornamental plants. Today, the editor will briefly talk about the causes of the yellowing of the golden diamond leaves and the solving measures. I hope it can be helpful to everyone.

1. Astigmatism irradiation

1. Planting golden diamond needs proper scattered light. If the light is too strong, it will burn the leaves and make them yellow.

2. Golden diamond plants grow slowly and turn yellow when they are kept in a cool place for a long time and lack of light.

3. Put the golden diamond in the place where the astigmatism is irradiated to avoid excessive light and exposure.

4. Appropriate shading measures should be taken in summer.

Temperature and humidity control

1. Growth habits of golden diamond

High temperature and humidity requirements, if the temperature is too low or too high, humidity does not meet the growth of the gold diamond, will lead to the golden diamond yellow leaf phenomenon.

2. the most suitable temperature and humidity for the growth of golden diamond.

A, temperature: the most suitable temperature is 20 degrees, not less than 10.

B, humidity: the most suitable humidity is in the range of 50-70%. If the humidity is less than 50%, the dry edge of yellow leaves will appear.

3. Humidity in the air can be increased by spraying and sprinkling water.

Third, rational watering

1. Although the golden diamond likes the moist growth environment, it can not be too wet for the basin soil, so it needs reasonable watering.

2. Spring and summer: keep the soil moist; autumn and winter: dry and wet; when the winter temperature is lower than 15 degrees, dry and wet alternate watering is needed.

3. Too much watering is harmful: the young leaves are dark and yellow, the branches are small, and the new shoots grow slowly.

4, too little watering harm: withered leaf tips, old leaves withered and yellow shedding.

4. Select good soil and apply fertilizer skillfully

1. When there is a lack of trace elements such as nitrogen, phosphorus, potassium and magnesium in the golden drill soil, it will cause the leaves to yellowing, as shown as follows:

2. Nitrogen deficiency in basin soil.

The leaves are small and yellowish, and then the whole plant loses green.

3. Phosphorus deficiency in basin soil.

The leaves are curly, dark green and yellowing between veins.

4. Potassium deficiency in basin soil.

The margin of the lower leaf is brown, easy to lodge.

5. Iron deficiency in basin soil

The scorched brown spots on the leaves dried up.

6. Magnesium deficiency in basin soil

The margin and middle of the leaf became greenish-white.

7. Therefore, when cultivating golden diamond, it is necessary to maintain the fertility and drainage of the soil, fertilize properly and supplement what trace elements are lacking.

V. Pest control

1. Pest damage

It mainly harms the leaves, slows down the plant growth rate, and in serious cases, it will lead to plant death.

2. Major insect pests

Red spider.

3. Methods of pest control

A, spray water frequently and wipe the leaves to prevent red spider pests.

B, spray professional pesticides for control, such as triclofenac, which is common, etc.
