WANT TO GROW ORCHID AT YOUR HOME?

NORTHERN & EASTERN EXPOSURE
Many orchids can be grown and flowered on a windowsill. Choose the brightest windows in your house that are not shaded by nearby trees and buildings. If you only have clear northern exposure, or even partially obstructed Eastern exposure, you should still be able to grow some orchids. If you have some outdoor space, even a small balcony, your orchids will enjoy a summer vacation outdoors in bright indirect light.

What You’ll Need
Windowsill growing requires no special fixtures, other than a humidity tray on which to place your potted plants, and a nearby spray bottle to mist your plants occasionally. Supplemental artificial light, especially in winter, may be needed in northern exposures.

Growing Guide
Keep your plants as close to the glass as possible. Light intensity falls off rapidly even a foot away for a window. After light, maintaining adequate humidity is probably the biggest problem in windowsill growing, especially in the winter months. Group plants, and spray them often with a water mister to help increase humidity. Be sure to keep moisture-loving orchids well watered at all times. Watering and fertilizer will also need to follow a more natural seasonal schedule with greatest frequency during the brighter warmer summer months and less during winter.

Insect pests can be gently washed or scraped off your plant, or treated with a natural insecticidal soap or horticultural fine oil. Isopropyl alcohol, which is available at drug stores, can also be used to spot treat plants. Be sure to carefully read all instruction labels on insecticides and only use those recommended for indoor use.
