Propagation and Cultivation of Cymbidium hybridum

It is usually propagated by the method of dividing plants. The ramet time is longer than that after flowering and before the new bud grows, this short dormancy period takes place. It should be properly dried before ramet and operated when the roots are slightly whitish and soft. Those with strong growth usually split once in 2-3 years, and each clump of orchid seedlings should have 2-3 pseudobulbs, one of which must be newly formed in the previous year.

To avoid wound infection, you can apply sulfur powder or carbon powder. Put it in a dry place for 1-2 days and then plant it separately, that is, it will become a new plant. After planting, it should not be watered immediately. It is found that if it is too dry, a small amount of water can be sprayed to the leaf surface and basin surface to prevent the leaf from drying up, falling off and the false bulb from shrinking seriously. Wait for the new bud base to produce new roots before watering.

Cymbidium can use 2 parts of fern root, 1 part of charcoal moss or 1.5-2 cm diameter bark as pot substrate, and can also add some granular materials such as broken bricks and charcoal. Flowerpots should choose high tube flowerpots with a diameter of 15-20 cm, with 2-4 seedlings in each pot.

Flower Cymbidium likes higher air humidity, spring, summer and autumn, while giving sufficient water to the roots, it should often spray water on the leaves. However, during the short dormancy period after flowering in early spring, Cymbidium must be watered less and more watering only when the new buds grow larger and new roots.

The plant of Cymbidium is large, its growth is luxuriant, and it needs more fertilizer than the general national orchid, so fertilizer should be strengthened in the growing season. Generally, the fermented cake fertilizer and so on can be mixed with 1x3 clay, then add water to make a ball about 2 cm in diameter, dry and set aside.

Put in the basin in spring, there is a certain distance from the new bud, fertilizer can slowly release nutrients for orchid growth. Can be applied twice a year, several grains in each basin, can also be used to apply fermented liquid farm fertilizer, every 1-2 Mondays, can also be sprayed to the leaves and basin at 1:1:1 nitrogen, phosphorus and potassium compound fertilizer, the concentration should be 3-5%, 1-2 times a week. Stop fattening at the end of autumn.

Cymbidium flowers are more resistant to diseases and insect pests than ordinary Chinese orchids, but they are still attacked by various diseases in the process of growth. therefore, strengthening prevention is an important measure to cultivate Cymbidium. Generally, 1000 times diluted solution of chlorothalonil or carbendazim was sprayed on both sides of orchid leaves alternately every 10 days.
