How to plant Cymbidium seeds?

Cymbidium is a perennial evergreen herb of Liliaceae. It likes warm, moist and semi-shady environment. It has strong adaptability, drought tolerance, but not cold resistance, and is not demanding on soil. The suitable temperature for growth is 15-25 ℃, and the overwintering temperature is 0 ℃. It can be propagated by cutting, ramet, sowing and other methods. Let's take a look at how to plant Cymbidium seeds.

How to plant Cymbidium seeds?

The seeds of Cymbidium can be sowed in March every year, but because the seed particles are small, the covering soil above the seeds should not be thick, generally 0.5 cm. Under the condition of 15 ℃, the seeds of Cymbidium can germinate for about 2 weeks, and then transplant and culture after the seedlings take shape. It is worth noting that when the varieties with leaf art are propagated by seeds, their offspring are degenerated into all-green varieties.

Planting substrate of Cymbidium

1. Matrix: Cymbidium has strong adaptability to all kinds of soil, and it is very easy to cultivate. Fertile sandy loam, humus, peat or fine sandy soil can be used as pot soil with a small amount of base fertilizer.

2, containers: hanging orchid planting flowerpots are relatively casual, but white porcelain flowerpots or plastic flowerpots are better, with a height of about 15 to 20 centimeters, which is quite fresh and elegant when matched with hanging orchids.

The Culture method of Cymbidium

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

2. Temperature: hanging orchid likes 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: Diaolan likes water, has strong drought resistance, and needs more water during the peak growth period from March to September, so it should be watered and sprayed 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: Cymbidium is a more fertilizer-tolerant plant. If there is not enough fertilizer and water, it is easy for the scorched head to grow old, and the leaves turn yellow and lose its ornamental value. For those who have begun to grow small plants, nitrogen fertilizer is applied once every half a month, and those with good growth are not allowed to apply nitrogen fertilizer.

5, change the basin: the hanging orchid should change the basin once every March, if the basin is deeper and the base fertilizer is enough, the basin can be changed once every two years. When turning the pot, knock the plant out of the basin, cut off the withered roots and excess roots, replace it with new culture soil and apply sufficient base fertilizer.

6, diseases and insect pests: hanging orchid is generally not easy to occur diseases and insect pests, the occurrence of diseases is generally stagnant water in basin soil, poor ventilation caused by root rot and root rot, should be timely spray control. The dense plant clusters are poorly ventilated and are vulnerable to scale insects, so prevention should be given priority to.

7. Pruning: the orchid should cut off the yellow leaves at any time and turn the basin once a year in March to 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 Cymbidium.
