Orchid Cultivation

In nature orchids (Family Orchidaceae) living epiphytic on twigs of trees and other plants, but in order to grow orchids can be grown in pots filled with certain media. There are several factors that affect plant growth, such as environmental factors, such as sunlight, humidity and temperature as well as maintenance such as: fertilizing, watering and pest control.

In general, cultivated orchids require the temperature 28 + 2 ° C with minimum temperature 15 ° C. Orchid soil is generally more refractory than the orchid pot. But high temperatures can cause dehydration which can inhibit plant growth.

Relative humidity (RH) needed for orchids ranged between 60-85%. The function of high humidity for plants, among others, to avoid evaporation is too high. At night, humidity is maintained so as not too high, because it can cause root rot on young shoots. Therefore, it is cultivated for the media in the pot should not be too wet. While a very low humidity during the day can be overcome by providing a spray mist (mist) around the plantation with the help of sprayer.

Based on the pattern of growth, orchid plants can be divided into two types namely, simpodial and monopodial. Orchids are orchids simpodial type that has no main stem, flowers out from the tip of the stem and flowering plants that come back from the child grows. Except in the orchid species Dendrobium sp. who may issue the new flower stalks on the sides of the trunk. Examples of orchid simpodial types include: Dendrobium sp., Cattleya sp., Oncidium sp. and Cymbidium sp. Orchid type simpodial in general are epiphytes.

Orchid monopodial type is characterized by the point of orchids that grow there at the end of the stem, pertumbuhannnya straight up on one stem. Flowers out of the trunk between the two axillary panicles. Examples of types of monopodial orchids are: Vanda sp., Arachnis sp., Renanthera sp., Phalaenopsis sp., And Aranthera sp.

Habitat orchid plants can be divided into 4 groups as follows:

* Epiphytic orchid, orchid growing is riding on another tree without harming their host plants and require shade from sunlight, for example, Cattleya sp. require light +40%, Dendrobium sp. 50-60%, Phalaenopsis sp. + 30%, and Oncidium sp. 60-75%.
* Terrestrial orchid, the orchid that grows in the soil and require direct sunlight, for example Aranthera sp., Renanthera sp., Vanda sp. and Arachnis sp.
Terrestrial orchid plants need sunlight 70-100%, with afternoon temperatures ranged between 19 - 380C, and at night 18-210C. As for the orchid species Vanda sp. which requires very little shade broadleaf.
* Orchid litofit, the orchid that grows on rocks, and resistant to full sunlight, such as Dendrobium phalaenopsis.
* Orchid saprophyte, the orchid that grows in media containing humus or dry leaves, and require little sunlight, such as Goodyera sp
