Orchid care is not difficult, it is just different. Orchids have a reputation for being difficult to grow when in fact many varieties make excellent house plants. With proper culture an orchid can be in bloom for months each year and can live indefinitely. In this respect orchids are an excellent value as far as blooming plants go. A well cared for and varied orchid collection can provide continuous bloom every day of the year.
With over 800 genera, more than 25,000 species, and hundreds of thousands of registered hybrids, the orchid family is among the most diverse of the plant families. Over half of the orchid plants that are produced are Phalaenopsis. Other genera such as Cattleya, Dendrobium, Cymbidium, Oncidium, and Paphiopedilum.
Repotting orchids is essential to their continued good health and growth. If an orchid remains in the same medium for a very long time the plant will decline. Over time orchid medium decays and compacts and smothers the roots. The amount of time between repotting varies with the type of orchid, and the type of medium.
