Genus of forty species of epiphytic and terrestrial orchids, native to central and southern Asia and Australia; many hybrids exist on the market, with showy coloured flowers. They produce several flattened pseudobulbs, bound together by short fleshy rhizomes; every year, the plants produce new pseudobulbs, each of them carrying about ten long rigid leaves, ribbon-like, slightly curved, of a bright green colour, which can reach the 90-100 cm of length.
In spring, at the base of the pseudobulbs, develops a long erect stem, fleshy, which carries up to 15-20 big fleshy flowers, of white, yellow or pink colour. Several hybrids exist on the market, even with small or very big flowers. The flower is usually of a pale, pastel colour, and has a conspicuously mottled labellum; they remain in flower for weeks, for this reason they are among the most diffused orchids as cut flowers.
The most common Cymbidiums on the market are of Asian origin, and come from the mountainous areas of Central Asia, so they love places not too hot, with summer temperatures below 30 ° C, and cool winters, do not fear short frosts, although usually during the winter are grown in apartment or in cold greenhouse.
To promote flowering is good to grow the plants outdoors, in a cool place, until the arrival of the first cold winter, then bring the plant of cymbidium indoors or place it in a place protected from frost. Let’s remember to grow in a position that is not too sunny, but well-luminous and windy.
The ideal temperature for the cultivation of cymbidium orchids is around 18 °.C.
E When grown at home, place the cymbidium plants in well-ventilated rooms with a good degree of humidity.
It is essential to guarantee these orchids a high degree of brightness, so much so that in poorly lit environments, especially in winter, it is necessary to resort to artificial lighting to ensure the right degree of light to the orchids.

Cymbidium orchids, in nature, grow both as terrestrial plants and as epitife varieties, i.e. they have aerial roots and grow leaning against other plants that support them.
The home-grown cimbidium are all epitife; for this reason they are cultivated in a light, neutral or alkaline compound, formed by 1 part of garden soil, 2 parts of osmunda and 1 part of sphagnum, with the addition of pieces of bark, polystyrene or other incoherent material.
These orchids are to be repotted approximately every 3 years and the operation makes after flowering, so the period can be variable, although, for the health of the plant, it would be advisable to avoid the operation in the vegetative period.
In case your orchid has not produced flowers, the best time for repotting is in spring.
To proceed with this operation it is advisable to wet the roots, so that they are less fragile and there is no risk of breaking them.
Then all the old substrate that degrades over time must be eliminated, to provide the plant with a fertile and solid support.
It is essential to check that the substrate offers an excellent degree of drainage because water stagnation is very dangerous.
During the summer period, it water frequently, avoiding that the surface of the substratum dries between one watering and the other. Watering should be less frequent in winter. During the summer, or even in winter in the case of specimens grown at home, we frequently vaporize the foliage, to cool it and to provide an abundant humidity environment.
It is important to check that the substrate maintains the right level of humidity but that it is not soaked because the roots and the plant itself would be affected quickly.
Compared to other varieties, these orchids do not require a very high level of humidity, the right level is around 50 %.
After the flowering, it is possible to divide the tufts of pseudobulbs, repotting them individually; we remind you that the Cymbidium seem to bloom more easily if cultivated in little capacious containers, which allow the substratum to dry up more quickly and not to keep for too long an excess of water.
The new heads must be equipped with a certain number of pseudobulbs, at least 3 or 4 in order to have more possibilities of development.
Cymbidium – Cymbidium: Pests and Diseases
The leaves and stems can be infested by cochineals, which make the plants sticky and sooty, slowing down their growth. To eliminate the problem if it is not very common, it is possible to intervene manually, eliminating the cochineals with the help of a cotton ball with alcohol. These orchids can also be affected by aphids that must be countered with the use of special pesticide products available on the market to be used with moderation and care.
If subjected to sudden changes in temperature, humidity or lighting, they can easily lose their buds and flowers. Radical rottenness can occur in case of excess moisture, while poor lighting can lead to a lack of flowering and a deterioration of the plant.
