TAILIEUCHUNG - Role of potting media in the cultivation of orchids – A review

One of the most important components of pot cultivation of flower crops is the choice of growing medium. It should be well aerated medium with good water retention capacity and good drainage. And ideal growing medium needs to be able to anchor the roots and stems so that the plant will not topple over as it grows larger, yet it should provide adequate moisture, nutrient and aeration to the plant. The cost, local availability and experience in substrate are usually the determining factors for choosing a particular substrate type. Orchids, being an Epiphytic in nature spread their roots over the branches of trees exposing them fully, therefore, the type of media used for growing epiphytic orchids should provide a surface over which the plants can cling to. A good mixture of media is useful in terms of all vegetative and flowering parameters. An ideal growing media should provide healthy environment for roots. It should be inert, porous and resistant to organic decomposition. It should be cheap and easily available (Bose and Bhattacharjee, 1980). The vigorous and healthy root system in epiphytic orchids was first step towards ensuring maximum growth. Hence selection of ideal rooting media provides a high degree of success for profuse root growth. | Role of potting media in the cultivation of orchids – A review
