Most popular orchidss from the 600 or so species in existance come from the tropics of the Americas, but there are a few which grow in the higher elevations, and therefore require cooler conditions, hybrids are more tolerant than the species, as in most plants. These orchids can be varied in their cultural requirements, the hybrids are tolerant of wide ranges in temperature, and broadly speaking do best in an intermediate environment. There are many varieties however spread throughout the world, and cultural requirements differ widely amongst the species, hence the following is given as a general rule for most hybrids. Minimum night temperatures of 50F, depending on the plants' origin, are needed, but growth in summer is rapid at temperatures up to 88F. A humid atmosphere, propelled by a fan is beneficial. In hot weather shade sufficiently to ensure that the leaves are cool to the touch. If you are growing in the home give a bright situation but not direct sunlight, behind a net curtain, from April to September. These also make good conservatory plants as long as summer shade and good air movement can be provided. From March to September the medium should never be allowed to dry out completely. Water twice a week and fertilize fortnightly with a recommended orchid fertilizer. From October to February, no fertilizer is needed, but water the plants when the medium appears dried out. It is better to underwater as the plants can stand neglect more than over watering.
