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.

Difficulty: Moderately Easy
Instructions

Things You'll Need:

  1. Step 1

    Give orchids a humid environment - between 30 and 40 percent humidity. Bathrooms and kitchens are usually good, humid environments.

  2. Step 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. Step 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. Step 4

    Grow orchids under a wide-spectrum fluorescent light if you don't have enough light from windows.

  5. Step 5

    Spray the orchids with a fine mist of water daily.

  6. Step 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. Step 7

    Fertilize weekly using half the recommended amount of specially designed orchid fertilizer.

  8. Step 8

    Repot orchids approximately every two years (see "How to Repot Orchids," under Related eHows).

Tips & Warnings
  • Use a device called a hygrometer to measure humidity.

on 5/9/2008 Placing a gravel- and water-filled tray in the home is an excellent way to promote the growth of fungus without changing the humidity even one little bit.
A vanda, in a pot, in an east-facing window will not only never, ever flower, it will decline in vigor for years until it finally dies.
Vandas and phalaenopsis require fairly opposite care - aside from both being heat-tolerant, they have very little in common with regards to growing conditions.
