How to raise green leaf orchid?

The green leaf orchid is one of the common family foliage flowers that people like. It is a perennial evergreen herb of the Liliaceae. It has bright green leaves, leaf shape such as orchid, fresh and elegant, and has a very strong function of absorbing poisonous gases. In general, the poisonous gas in the air can be completely absorbed. Let's take a look at how to raise the green leaf orchid together.

Growth habits of Cymbidium chinense

The green leaf orchid prefers warm, humid, semi-shady environment, strong adaptability, drought tolerance, not very cold tolerance, no choice of soil, and grows better in well-drained, loose and fertile sandy soil. Light requirements are not strict, generally suitable for growth in medium light conditions, but also resistant to weak light. The suitable temperature for growth was 15: 25 ℃, the overwintering temperature was 5 ℃, and the growth stopped above 30 ℃. The plants could grow normally at room temperature above 12 ℃ in winter. If the temperature was too low, the plants would grow slowly or dormant, and chilling injury would occur if the temperature was lower than 5 ℃.

The Propagation method of Cymbidium

1. Cutting: it can be carried out at any time from spring to autumn, cut the clustered stems and leaves on the stolon and plant it in a flowerpot directly, pour through water and keep it in the shade, be careful not to bury it too deep, otherwise it is easy to break your heart.

2. Ramet: when the plant is divided, the plant can be pulled out of the pot, the old soil and rotten root can be removed, and the old root can be cut open, so that there are three stems on the divided plant, and then transplanted and cultured respectively.

3. Sowing: it is carried out in March every year, because the seed particles are not large, the covering soil above the seeds should not be thick, generally 0.5 cm. Under the condition of 15 ℃, it can sprout for about 2 weeks, and then transplant and culture after the seedlings take shape.

How to raise green leaf orchid?

1. Light: the green leaf hanging orchid likes the semi-shady environment and is very sensitive to light. the leaves will wither and yellow in summer and autumn when the sun shines directly, even the whole plant will die. In winter, because the sun is not strong, it can make the green leaf orchid accept some direct sunlight properly.

2. Temperature: green leaf Cymbidium prefers warm and humid climate, can not tolerate severe cold and heat, the optimum growth temperature is 15: 25 ℃, and the room temperature in winter should not be lower than 5 ℃. Avoid strong light in high temperature, but see more sunshine in low temperature and cold.

3. Watering: the green leaf hanging orchid likes water, has strong drought resistance, and needs more water during the peak growth period from March to September, so it is necessary to water and spray frequently to keep the basin soil completely moist. In the winter dormant period, you can wait until the surface of the basin soil is about 1 cm deep dry before watering.

4. Fertilization: the green-leaf orchid is a more fertilizer-tolerant plant, the scorched head is easy to grow old when the fertilizer and water is insufficient, the leaves turn yellow and lose the ornamental value. If the green-leaf orchid that has begun to grow plantlets is applied nitrogen fertilizer once a half month, it is OK not to apply nitrogen fertilizer to the green-leaf orchid that grows well.

5. Soil: green leaf hanging orchid should use light and fertile sandy loam, which requires that the soil contains humus and strong permeability. Pot cultivation can use the same amount of humus or peat soil, garden soil and river sand as substrate.

6. change the basin: the green leaf hanging orchid should change the basin once a year in March. If the basin is deeper and the base fertilizer is sufficient, the basin can be changed once every two years. When turning the basin, the plant will be knocked out of the basin to cut off the withered roots and excess roots, replace with new culture soil and apply sufficient base fertilizer.

7, diseases and insect pests: green leaf hanging orchid is generally not easy to occur diseases and insect pests, the disease is generally caused by stagnant water in basin soil and poor ventilation, so it should be sprayed and prevented in time. The dense plant clusters are poorly ventilated and are vulnerable to scale insects, so prevention should be given priority to.

8. Pruning: the green leaf hanging orchid should cut off the yellow leaves at any time, turn the basin once in March every year, and cut off the old root, rotten root and excess fibrous root. The old leaves of Cymbidium can be cut off in the first and middle of May, which will promote the germination of more new leaves and small green leaves.
