[what to do if the golden diamond leaves turn yellow] how to raise the golden diamond

Golden diamond vine green velvet is a popular evergreen foliage plant in recent years. Golden diamond leaves are evenly matched, moderate tension, thick and green leaves, rigid brightness, high ornamental value, but if the maintenance and management is not proper, it is easy to appear the phenomenon of yellow wilting of golden diamond leaves, which will not only affect the beauty of the plant, but also affect the growth of the golden diamond, and seriously cause the death of the plant. Therefore, when the golden drill appears the phenomenon of leaf yellowing, we should find out the cause in time and correct it.

What if the golden diamond leaves turn yellow?

The main causes of leaf yellowing are discomfort of temperature, low humidity, discomfort of light, excessive fertilization, frequent watering and pests.

The temperature needs to be kept at about 20 ℃, not less than 10 ℃, and to avoid heating, air conditioning and cold air.

Air humidity is required to be kept between 50-75%, less than 50% of the dry edge of yellow leaves, often by spraying and sprinkling water to increase air humidity.

Like the light and avoid 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 a shady environment for a long time, otherwise the leaves are very easy to yellowing.

Prevention and control methods:

1. The temperature needs to be kept at about 20 ℃, not less than 10 ℃, and to avoid heating, air conditioning and cold air.

two。 The air humidity is required to be kept between 50% and 75%, which is less than 50% of the dry edge of yellow leaves. Water spraying and sprinkling are often used to increase air humidity.

3. Like the light and avoid 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 a shady environment for a long time, otherwise the leaves are very easy to yellowing.

4. Fertilization should be based on the principle of diligent application of thin fertilizer and mainly nitrogen fertilizer.

5. 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.

5. Diseases are mainly caused by maintenance or environmental discomfort, which can be prevented by good maintenance and management, and can be prevented by spraying carbendazim and chlorothalonil. 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.

Hydroponic method of gold drill

The hydroponic flower root system is soaked in the nutrient solution, and the buffer capacity of the nutrient solution is worse than that of the substrate. Due to the metabolism of plants, new roots continue to grow, and the roots may also secrete some toxic substances, which have adverse effects on root growth and development. In addition, because different flowers have different absorption of nutrients, it is selective, so it often causes nutrient imbalance in the nutrient solution.

Sometimes it will cause physiological diseases caused by element deficiency, and it will also cause imbalance due to the effect of temperature on PH, especially in hydroponic culture. Therefore, hydroponics should be changed regularly. The liquid was changed once a month in winter, spring, autumn and each season, and once every 25 days in summer. Therefore, a good nutrient solution must have a strong buffer capacity, which can stabilize the plant growth environment and ensure the balance of nutrients.

Culture method of golden diamond

① soil: Golden diamond does not have strict requirements on soil, and it is better to grow in sandy loam soil rich in humus and good drainage. Potted soil is often mixed with peat and perlite to prepare nutrient soil.

② lighting: except for strong shading in summer, try to give golden diamond better light in other seasons, especially in winter, the light must be sufficient.

③ watering: in addition to keeping the gold drill basin soil moist at high temperature (above 26 ℃), the topsoil must be watered thoroughly after the topsoil is dry.

④ fertilization: a small amount of fertilizer can be applied for many times between 16 and 30 ℃, and no fertilization should be applied as far as possible when the temperature is below 15 ℃ or above 30 ℃.

⑤ ventilation: if the outdoor temperature can be above 15 ℃, ventilation as much as possible, which is beneficial to the growth of gold diamonds.

⑥ pruning: if the golden diamond leaves turn yellow, sometimes normal physiology will appear, as long as it is cut off.

⑦ humidity: it is best to keep it above 75%, the golden diamond is not resistant to dry, like wet environment!
