What are the breeding methods and matters needing attention of hanging orchids in "asparagus"? What kind of fertilizer does it grow well?

Hanging orchid also known as: hanging pot grass, hanging orchid, fishing orchid, bluegrass, folding crane orchid, air guard, Western Europe, also known as spider grass or aircraft grass, originated in South Africa. There are many kinds of hanging orchids, each with different forms and characteristics. There are five common ones: such as orchids, purple orchids, flower orchids, gold leaf orchids, silver-edged orchids. So what are the breeding methods and matters needing attention of hanging orchids?

Cultivation conditions of Cymbidium

Environment: the growth of Cymbidium is mostly in the shady and humid environment, and most of the potted plants grow in fertile land, like semi-shady environment, and have a strong drought tolerance advantage. Sufficient sunshine is needed for growth, which is suitable for planting in the courtyard and balcony.

Lighting: the hanging orchid is not resistant to cold, and the lighting requirements are random, but the best suitable lighting is medium, preferring weak light.

Temperature: hanging orchid planting, the suitable temperature is 15-25 degrees Celsius, cold winter, can adapt to the lowest temperature of 5 degrees Celsius, while the summer temperature as high as 35 degrees Celsius, the need to cool down, up to more than 30 degrees Celsius, will stop growing.

Propagation method of Cymbidium

There are three propagation methods of Cymbidium, which are cutting, ramet, sowing and propagation.

Cutting method

This kind of propagation method, mostly for spring and autumn to adapt to the season, can also directly intercept the clustered stems and leaves on the strong orchid, and then load them directly into the prepared flowerpots, pour enough water to fix the roots, and maintain them in a cool place. After a week, it can be propagated successfully. The number of propagation of orchids can be changed according to the size of flowerpots, small flowerpots can be cut about 2, while large flowerpots can be cut about 5.

Split-plant method

This kind of breeding method has a very high survival advantage, that is, it directly transplants the growing Cymbidium, because the Cymbidium has the reproductive advantage and the clustering speed is faster. A hanging orchid was lifted out of the flowerpot, then the old soil and old roots were arranged, the roots were cut, and the stems and leaves were reserved for planting respectively.

Sowing method

The flower species of Cymbidium plants are mostly propagated in spring and can be picked in March. Because the flower species of Cymbidium are relatively small, about 0.5 cm, they can be sown mainly, which can adapt to the air temperature of 15 degrees Celsius. In the normal temperature environment, they can germinate after two weeks and wait directly for germination and shaping, and then the seedlings can be transplanted.

Planting steps of Cymbidium

① container preparation: hanging orchid planting, choose flowerpot, you can choose to use glassware to enhance the ornamental value.

② soil preparation: planting Cymbidium, transplanting seedlings should prepare pot soil, can be directly in accordance with the same proportion, sand, peat soil, humus soil mixed, then add a small amount of base fertilizer, put into the planting utensils.

③ transplantation: the prepared or purchased seedlings will be implanted in the soil, and then poured enough water to fix the roots. And the placement of the orchid, usually located in the room with fewer windows, can be planted in the bedroom with the back sun, and should be far away from the sunny ground, kitchen and other areas.

④ light maintenance: daily, should try to avoid direct contact with strong sunlight, otherwise very easy, it will lead to hanging orchid leaves yellowing, can adapt to the temperature of about 15 degrees Celsius, cool low temperature, hanging orchid growth more healthy, leaves oily, yellow Phnom Penh more obvious.

⑤ watering: in hot summer, watering can take a small number of methods, and every day at noon, spray should be used to cool the leaves, not only to maintain moisture, but also to clean up the surface dust, and Cymbidium is a succulent plant, leaves can store water, can exercise its ability to resist drought. In winter, the temperature is as low as 5 degrees Celsius, should be less, basin soil to avoid stagnant water, damp, otherwise it will be yellow because of its leaves.

⑥ fertilization: the most common disease in the planting of Cymbidium is the yellowing of leaves, and the lack of fertilizer and water is the most common cause of this phenomenon. The frequency of fertilization can be maintained every 7 days, choose organic fertilizer, mainly liquid, to avoid direct contact with the root. Secondly, you can also choose bone powder, which can be applied every half month to protect the flowers and leaves and make them brighter. In addition, liquid fertilizer should be maintained once a week, and daily exposure to nitrogen fertilizer should be avoided as far as possible.

⑦ pruning: plant pruning is an important step in cultivation, while Cymbidium pruning is mainly aimed at rotten yellow leaves. While keeping turning the soil every 3 months, old roots and excess fibrous roots should be cut off to promote the reproduction of new buds and new leaves. If it is not pruned for a long time, it will cause too many roots of Cymbidium, which will rot and grow after accumulation.

Matters needing attention in planting Cymbidium

Pest control

1. Mites: Cymbidium breeds mites, mostly in summer, which is mainly caused by lack of daily ventilation and low plant leaf humidity. 1000 times dicofol can be used as the treatment.

two。 Root rot: root rot disease, when serious, need to remove the whole plant, and the disease is mild, you can choose to use wet powder spray, each plant can be sprayed about 2 grams. As for poor prevention, you can choose to fill the root with 1500-3000 times.

3. Whitefly: after the emergence of whitefly disease and insect, it will spread rapidly, at this time, we should choose to use wet powder, its concentration is 500 times, can be used 4 times in a row.

4. Shell insects: this kind of disease and insect will emit a thick, strong smell and sticky leaves in the severe stage. Can be every other week, then spray this omethoate, the concentration is 1000 times, with spray as the treatment.

The leaves turn brown

Hanging orchid leaves are evergreen, brown is an abnormal phenomenon, and there are many reasons for this. If the sunshine time is too long, or the cold winter is frozen, can not be moved to indoor heat preservation in time, the leaves of the orchid become brown, mostly caused by freezing, but this phenomenon will not cause the decay of the whole plant, and the brown part is mostly the edge of the leaf.

At this time, it is necessary to heat preservation the orchid in time, move it to a bright and warm environment, at the same time, prune a dead branch and leaf, and strengthen fertilizer and water management to avoid decaying branches and leaves to absorb nutrients, and brown leaves will recover quickly.

Summary: hanging orchid planting methods and matters needing attention as above, hanging orchid planting, should pay attention to watering, fertilization, secondly, should have professional cultivation knowledge, to the hanging orchid can encounter a variety of diseases and insects, have the ability to prevent and treat.
