How to Care for Intermediate-Growing Orchids

By eHow Home & Garden Editor

Rate: (4 Ratings)

Intermediate-growing orchids, including cattleyas, dendrobiums, many oncidiums and some paphiopedilum, prefer nighttime temperatures between 55 and 60 degrees F and daytime temperatures between 65 and 80 degrees F. Here's how to keep them healthy and beautiful.

Instructions

Difficulty: Moderately Easy

Things You’ll Need:

Step1
Give orchids a humid environment - they require between 30 and 40 percent humidity. Bathrooms and kitchens are usually good, humid environments.
Step2
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.
Step3
Give orchids bright but not direct light. Place the pots on a shelf by an east- or south-facing window or under a skylight.
Step4
Grow orchids under a wide-spectrum fluorescent light if you don't have enough light from windows.
Step5
Spray the orchids with a fine mist of water daily.
Step6
Water orchids that are in pots less than 8 inches in diameter twice a week. Water orchids in pots bigger than 8 inches once a week.
Step7
Fertilize weekly using half the recommended amount of specially designed orchid fertilizer.
Step8
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 11/22/2005 Even if you don't have a humidifier, a quick way to give your orchids a boost every now and then is to set a kettle near them after you've boiled water. I do it every time I have a cup of tea.
