What if the leaves of Codonopsis pilosula turn yellow

Copper money grass for umbelliferous perennial herbs, spreading ability is very strong, for excellent ground cover plants, many people like to cultivate at home, because lovely, good to feed, but the breeding process is not always smooth, there will always be some accidents, such as copper money grass leaves yellow, let's take a look at copper money grass leaves yellow how to do it!

The reason for the yellow copper leaf.

1. Pouring "half water", that is, watering is not thorough, and there is no seepage phenomenon in the basin bottom.

2, winter cold, roots have frostbite.

3, after winter, eager to go out of the room, put in a warm place in the sun, temporarily unable to adapt to the sudden change of climate.

4. The basin soil has been too wet or dry for a long time, and it has not been watered when it is dry.

5, long-term placed in poor ventilation conditions of the environment.

6, the leaves are not sprayed for a long time, dust accumulation, hindered photosynthesis.

How to prevent yellow copper leaves

1, full hydroponic words easy to lack nutrition, grow not as good as soil culture. The whole soil culture is often not enough water, and it is poured to the bottom of the basin every day. Half-water and half-soil cultivation is best.

2, the sun should be very enough, a little shade will grow bad.

3, the roots grow very fast, will keep the site up and accumulate in the basin, a long time to absorb too much nutrition, but the leaves are not enough nutrition. So every two or three months, you have to clean up and change the pot. Throw away the excess roots and leave a small section. Copper money grass is a cheap plant, very easy to survive. A small stem with a little root can grow into a large pot.

4, a little fertilizer every month will grow better.

The cultivation method of copper flower grass

1, soil: copper money grass on the soil requirements are not strict, whether it is yellow loam, red loam or black loam, even in poor soil can also grow. However, its drought resistance is not strong, and it is most suitable for growth in fine, acidic, humid and low fertility loam. It is suitable for cultivation in fertile and loose soil with large water absorption and good water retention. It can also be cultivated in moist river banks, swamps, grasslands or fresh water with low hardness. The cultivation soil can be mixed with rotten leaves, river mud and garden soil in a ratio of 5:2:2.

2, light: copper money grass shade tolerance, to half sunlight or shade is the best, avoid strong direct sunlight, the more shade the environment is more likely to lead to plant leaves rot. The copper flower grass does not compete for glory, but if the copper flower grass receives 4 to 6 hours of scattered light every day, or gives it 8 to 10 hours of artificial light, it will make the copper flower grass grow better.

3, temperature: copper flower grass likes warm and humid environment, but not cold, in the temperature environment of 10~25℃ grow well, summer temperature rises to 32℃ above, will stop growing, winter temperature shall not be lower than 5℃.

4, fertilization: copper copper grass on the fertilizer demand is more, the growth stage copper copper grass every 2 to 3 weeks topdressing. If planted in potted plants or containers, a small amount of fertilizer is required, such as quick-acting fertilizer Huabao No. 2, which can maintain fertilizer efficiency for a long time in water and ensure that the water quality is slightly acidic or neutral.

5. Watering: Copper flower grass likes to grow in a humid environment. Because of its many leaves and large transpiration, it is often necessary to spray water to the plants in summer to maintain a high air humidity, and the leaves should be kept clean to facilitate photosynthesis. Winter basin soil to partial dry is appropriate, watering follow the principle of wet rather than dry, avoid ponding, otherwise easy to rot roots. The tap water in the north should be used for 1~2 days after standing in the sun. Water every 2~3 days during the growth period to keep the pot soil moist. Water is changed once every 7~10 days in spring and summer, and once every half month in autumn and winter. If water is maintained, change the water once a week and add special nutrient solution for foliage plants. If soil culture is used, it must be kept water for a long time. Water should be poured once a day in the morning. The moisture should not be too sufficient. The bottom outlet should be used to ensure that the basin soil is soaked.

6. Pests and diseases: There are very few pests and diseases in copper coins. Strong growth adaptability, no need for deliberate care. After a period of cultivation, the copper money grass will fill the entire container. Water is often sprayed on the leaves to keep them green and shiny. After dense growth, ventilation should be paid attention to, otherwise the plant is easy to yellow.
