Care for Warm-Growing Orchids

Warm-growing orchids, including vandas and phalaenopsis, 

prefer nighttime temperatures between 60 and 65 degrees F

 and daytime temperatures between 70 and 85 degrees F. 

Here's how to take care of these plants.

1. 1. Give orchids a humid environment - between 30 and 40 percent humidity. Bathrooms and kitchens are usually good, humid environments.
2. 2. Increase humidity in the environment by setting the orchid pot on a tray filled with gravel and water; this helps raise the humidity around the plant.
3. 3. Give orchids bright but not direct light. Place the pots on a shelf by an east- or south-facing window, or under a skylight.
4. 4. Grow orchids under a wide-spectrum fluorescent light if you don't have enough light from windows.
5. 5. Spray the orchids with a fine mist of water daily.
6. 6. Water orchids in pots that are less than 8 inches in diameter twice a week. Water orchids in pots bigger than 8 inches once a week.
7. 7. Fertilize weekly using half the recommended amount of specially designed orchid fertilizer.
8. 8. Repot orchids approximately every two years (see "How to Repot Orchids," under Related eHows).
