ORCHIDS
Orchids are far tougher and hardier than most people think. Orchids are
different from other houseplants as they do not grow in soil. Orchids can be
grown in pots filled with bark, stones, orchid potting mix or other loosely
packed material. Do not use any soil. Roots can even be exposed to the air
and misted with water. Nothing kills an orchid faster than letting it sit in
water.
Watering:
You can water the orchids thoroughly about twice per week. If you are
unsure if you need to water your orchid, wait a day. Also, keep in mind that
orchids need less water during their dormant period. You can water them
about once per week in the winter.
Temperature:
Another difference between orchids and many houseplants is that in nature
most orchids experience a big difference between day and night
temperatures. Manipulating the temperature of the home so it will drop at
least 10 degrees at night, especially in fall and winter when many orchids
initiate buds, will induce the orchids to set flower buds more readily.
Warm-growing orchids, such as phalaenopsis, droop if temperatures drop
much below 60 F. Intermediate growers, such as cattleyas, prefer winter
nights around 55° F. Cool-growing orchids, including cymbidiums and
odontoglossums, are accustomed to winter nights of 50 F. At the other
extreme, most orchids perform poorly when exposed to temperatures above
90° F.
Light:
Most orchids enjoy medium light, but vary greatly. Be sure to provide at
least six hours a day of lgiht. Many orchids can withstand more or less than
the amount of recommended light, but providing more light enhances
flowering potential. Conversely, inadequate light prevents orchids from
flowering, although they will grow.
