"perennial evergreen vine" what are the breeding methods and matters needing attention? What if the leaves turn yellow and the leaves fall?

Cymbidium angustifolia is another name: Cymbidium angustifolia, Niukouteng, Cymbidium angustifolia, Polygonum polygonum, which is not only different genera but also different families, is two different plants. Cymbidium is a perennial evergreen vine of Polygonaceae, which has full plant shape, whirling branches and leaves, and has high ornamental value. The following is to introduce the breeding methods and matters needing attention of Cymbidium.

Cymbidium is native to New Zealand. The plants of Cymbidium are creeping or overhanging, and their slender stems are reddish brown. Leaflets alternate, leaf blade cordate or rounded. Its full plant shape, whirling branches and leaves, with high ornamental value, suitable for hanging pot planting or put on the top of several shelves, cabinets, stems and leaves naturally drooping, covering the whole flowerpot, like a green ball, very good-looking.

Culture methods and matters needing attention of Cymbidium

1. Temperature

Cymbidium likes warm and humid climate and is not resistant to cold. It grows fastest at 20 ℃ and stops growing at more than 30 ℃. The leaves are prone to yellowing and dry tip. Therefore, summer heat prevention and cooling should be paid attention to ventilation, and cultivation should be carried out in the greenhouse in winter. The overwintering temperature should be 10 ℃, not lower than 5 ℃.

2. Lighting

Outdoor cultivation in summer should pay attention to shading, so as not to make the light too strong, otherwise sunburn is very easy to occur. Pay attention to daylighting when overwintering in the shed in winter to prevent the lack of light and the color of the leaves.

3. Soil

In pot cultivation, rotten leaf soil or peat soil, garden soil and river sand are often mixed with a small amount of base fertilizer as substrate. Change the basin every 2-3 years and re-prepare the culture soil.

4. Watering

The fleshy root of Cymbidium has well-developed water storage tissue and strong drought resistance, but it needs more water during the peak growth period from March to September, so it should be watered and sprayed frequently to increase humidity; the basin soil should always keep moist and spray branches and leaves with water close to room temperature to prevent dry tip, but can not accumulate water. The amount of water gradually decreased after autumn to improve the cold resistance of the plant.

5. Fertilization

During the peak growth period, dilute liquid fertilizer was applied twice a month. Nitrogen fertilizer is the main fertilizer, but Jinxin and Phnom Penh varieties should not apply too much nitrogen fertilizer, otherwise the line spot of leaves will not become obvious.

6. Pruning and changing pots

As the plant grows, the old leaves at the base should be cut frequently in order to maintain a good plant shape. In addition, the orchid has strong sprouting power, fast growth, easy to grow all over the basin, and the basin should be changed every two years.

7. Pest control

The dense plant cluster of Cymbidium is poorly ventilated and is vulnerable to scale insects, so prevention should be given priority to. If scale insects occur, 50% marathon emulsion 1000Mel 1500 times can be sprayed once every 7 days, and 2 Mel can be sprayed for 3 times.

[tip] Chiba can also be hydroponically cultured, using tap water that precipitates for a day and changing it once a week. It usually grows well without nutrient solution in summer. When changing water, take the clover out of the basin, rinse the root with water, and put it directly into the precipitated water. Hydroponic containers should be shorter, bigger bellies, and look better. Remember that hydroponics should also sprinkle water on the leaves every day.

The leaves of Cymbidium are yellowing.

The reason for the yellowing of the leaves of Cymbidium

The light is too strong, or the lack of light is one of the reasons, and another reason is the high temperature.

Chiba prefers semi-shady environment, and the suitable growth temperature is between 20-24 ℃. This determines that Chiba is not suitable to grow in an overheated temperature, of course, this growth habit shows that Chiba also has high requirements for light.

If the light is too strong or insufficient, the leaves will easily turn yellow, lack of vitality, and lose their due ornamental value. The temperature should not be too high, if the temperature is more than 30 ℃, thousands of leaves will stop growing, and the leaves are prone to yellowing and dry tip.

What if the leaves of Cymbidium are yellowing?

The solution to the yellowing of the leaves of Cymbidium is also very simple.

If it is the cause of lighting, it is necessary to find a solution in this respect. Choose a semi-overcast environment, but to ensure that Chiba can receive enough sunlight every day, and must pay attention to shade in summer to avoid burns.

If it is the temperature, it is necessary to find a way to cool down the temperature.

The thousand-leaf hanging orchid shed its leaves.

The reason for the loss of leaves in Chiba

The loss of leaves is basically caused by lack of water or poor ventilation.

Chiba has a great demand for water during the growing period, so it should be watered and sprayed frequently to increase humidity. If it is not watered enough, it will not only not meet the growth needs of Chiba, but also lead to leaf fall.

Poor ventilation can lead to poor breathing, rotten roots, fallen leaves, and other problems such as the breeding of pests. Pests can also cause the loss of leaves.

What if Chiba loses its leaves?

Control moisture, reasonable watering, to ensure adequate moisture, but to avoid watering caused stagnant water, causing decay.

Peacetime maintenance is to pay attention to more ventilation, to ensure ventilation, but also to reduce the occurrence of diseases and insect pests.
