Orchids are tropical beauties. They are available in a wide variety, in fact there are more than 900 species of dendrobium orchids. Orchids are somewhat troublesome to grow, but if you know some basic facts the process is much simplified.

Orchids are becoming easier to grow in the home. If you have ever successfully grown a houseplant, you can grow orchids. There are several varieties available. Follow the directions for each different variety. The following is for general Orchid care.

LIGHT: No houseplant or Orchid will do well without adequate light. Most orchids will do well on a bright east or west windowsill or a lightly shaded south windowsill. A north window will rarely provide sufficient light. Do not compensate for poor light by extending hours of light. In fact, this may be detrimental to the plants health and may prevent flowering. Most orchids grown in northern climates will appreciate a summer vacation outside. Be especially aware of direct sun and protect shade-loving plants.

TEMPERATURE: Most orchid plants will be happy where you are comfortable, temperature wise. Typical home temperatures of 55-65°at night and 75-80° during the day are fine for most varieties. Watch for excessively low or high temperatures near the window glass.

WATER/HUMIDITY: Provide as much humidity as possible by grouping your plants and/or placing on a pebble-filled tray partially filled with water, being careful to keep the pots above the water level. Care must be taken to water only when needed. Usually plants in less light require water less often. A warmer, brighter environment will necessitate watering more often. Be sure to follow the watering requirements for each variety. Unless directed otherwise, do not allow the pot to sit in water. Feed with every watering with a liquid fertilizer mixed to 1/4 the recommended strength. Flush with clear water monthly to remove any excess salts.

Most orchids are grown in a loose, well-drained mix. This may be a bark mix, coir-based mix or sphagnum moss. Each has its own water-retentive properties so care must be taken to match water requirements of the plant and environmental factors with the right potting mix.

Varieties include Phalaenopsis, Dendrobium, and Oncidium-types. They may be available in 4" pots, but more commonly in 5" clay and 6" pots. Watch for unusual varieties that become available on a very limited basis.

Your local florist is a great source of information on dendrobium and other ochids on how to care for them. The more you know the longer your tropical orchids will last. All you have to do is call or stop at your flower shop. Satisfaction is only a purchase away.
