How to solve the problem of yellowing and blackening of Cymbidium leaves

Nowadays many people like to keep some plants at home. Among all the plants, hanging orchid is estimated to be a kind of indoor plant that many people will choose. If plants want to grow well, it has something to do with not only the technology of the people who raise the plants, but also the environment in which the plants are planted. Today, I will briefly introduce to you the planting method of Cymbidium, and the solution of yellowing and blackening the leaves of Cymbidium.

What if the leaves of Cymbidium are soft?

1. The softness of Cymbidium leaves is due to lack of water.

Under normal circumstances, hanging orchids will appear the phenomenon of soft leaves, because of the lack of water. There are two main manifestations of water shortage, one is that the soil is short of water, and the other is that the air is too dry. Therefore, in the cultivation of hanging orchids, watering should be supplemented from two aspects. First of all, the soil should be well watered to keep the soil dry. The second is to maintain a high air humidity, culture Cymbidium can not be too dry, too dry easy leaves scorched tip, leaves soft or even broken, at this time need to often spray water to leaves, keep moist.

2. The leaves of Cymbidium are soft and rotten.

In fact, it may cause the leaves of Cymbidium to become soft and its roots are rotten. In fact, there are many reasons for the rotten roots of Cymbidium, the more common is improper watering, too much watering leads to too moist soil, and even stagnant water, which makes it difficult for the roots to breathe and rot roots. After the roots begin to rot, the plant will appear listless and the leaves will be soft. When raising Cymbidium, we must pay attention to its growth status to avoid the phenomenon of rotting roots. In particular, watering, although the orchid is more like wet, but too much water, it is easy to rot.

The solution of yellowing and blackening of Cymbidium leaves

1. Improper fertilization: excessive fertilization causes yellowing of leaves, which exceeds the needs of the plant. At first, the leaves are bright and uneven, and then the roots rot, and the leaves are yellow.

Treatment method: should stop fertilizing, irrigate more water, or turn the pot to clean the root and replace the new soil.

2. Nutrient loss: all kinds of nutrient elements in the basin soil have been exhausted, the three elements of nitrogen, phosphorus and potassium have not been replenished in time, the plant is lack of nutrients, and the leaves are yellow and thin.

Treatment method: fertile loam and fertile water should be replaced in time.

3, lack of sunlight: although the orchid is a semi-negative flower, it should see more than four hours of astigmatism at least every day, otherwise the chlorophyll will decrease and the leaves will turn yellow.

Treatment: should set aside free time every day to put the orchid in the sun for a few hours, but not too much exposure to the sun.

4. poor air permeability and water permeability of basin soil: stagnant water in basin soil does not dry for a long time, root respiration is difficult, which leads to leaf yellowing.

Treatment method: loosen the soil and control moisture in time. Fifth, it is impervious to water for a long time. The roots of Cymbidium lose water, and the lower old leaves turn yellow. It should be watered thoroughly to keep the basin soil warm and moist.

Causes and Control methods of Leaf Tip withering of Cymbidium

1, the lack of light, light long-term shady environment, the leaves of Phnom Penh are easy to gold and green, easy to whiten and yellowing. The leaves are easy to grow, and the leaves are slender and soft, losing the bright gold and green, which is enough to enhance the light.

2. Another reason is the excessive application of nitrogen fertilizer and the lack of phosphorus fertilizer and potassium fertilizer. If there is too much nitrogen fertilizer, it is easy to make the plant leaves bigger and thinner and grow crazy. But there will be a lack of green, few blossoms and light colors. Phosphate fertilizer can promote the flowering and fruiting of plants and make the leaves green and flowers bright.

3. If too much water is watered, the root system will rot. Reduce the amount of water and recover after a period of time. Another possibility is that there is too little light, so just increase the light.

What to do after the orchid blossoms?

1, the hanging orchid likes the warm, humid, semi-overcast environment, want to let it bask in the sun more, but the summer should avoid the light, because the light is too strong will burn the hanging orchid.

2. Don't water too frequently, it mainly depends on the season and leaf conditions. For example, in summer, if you water it once in the morning or evening, you must water it thoroughly, taking the seepage of the basin bottom as the standard. In addition, it is found that the leaves have shrunk and have not spread out, and they also need to be watered thoroughly. Is there any sign of the flowering of the orchid? how to take care of the flowering of the orchid?

3. In terms of soil nutrients, Cymbidium should choose sandy soil with good drainage, loose and fertile soil, and apply more phosphorus and potassium fertilizer, which has a good effect on flowering and promoting flowering. Of course, you can also properly apply bone powder, eggshells and other retting organic fertilizer, diluted with water every half a month, can promote the flowering of the orchid.

Have you all learned the planting methods of hanging orchids introduced to you above? In fact, raising some plants indoors can improve the indoor air. Therefore, if there are conditions at home, it is recommended to plant some plants indoors. It can be an orchid, or it can be some other plant that is suitable for growing indoors.
