Understanding the natural growing habitats of orchids helps us to understand where they should be happiest in our home. In nature, most orchids grow in tropical climates with lots of humidity, ventilation, and filtered light. Here are a few tips for growing orchids indoors and outdoors.
Finding the Perfect Indoor Spot
Find a window that provides good filtered light throughout the entire day. In nature, most orchids grow in trees or within the landscape under trees and get filtered light from daylight until dark. Make sure the light your orchid receives is filtered with a sheer or screen. Don’t place a plant in a window with direct light as glass can actually intensify the light and cause burn.
Orchids do well in bathrooms as they provide plenty of humidity. However, not all bathrooms have a window which is needed to ensure proper lighting. If you don't have a sunny window, grow lights are an alternative option.
Also remember that humidity levels are important when growing indoors. Your air conditioner and heater are designed to remove humidity from the air. So you will need to provide additional humidity by misting your plants daily. Another alternative is to create a water reservoir with pebbles and a shallow dish filled with water to the top of the pebbles. By setting your orchids on top of the pebbles, your plants won't sit directly in the water - but humid air will rise around the plant to provide the humidity your plants need.
Outdoors with a view
Back porches, lanais or pool areas provide a great growing environment for your orchids. Just remember to place your orchid where it won’t receive direct sunlight. Be sure to check the light levels throughout the day as shadows and light patterns may change from the morning to the afternoon.
Typically, an outdoor environment provides natural humidity, but it’s still a good idea to keep an eye on the weather. During certain times of the year, the humidity can be very low and you may need to mist your plants. Also pay close attention to the type of orchids that you are growing. For example, vandas often require daily waterings.
Another benefit to outdoor growing is natural ventilation. However, during certain times of the year, the wind may be stagnant. Most plant diseases and insects thrive in hot, stagnant areas. A simple box fan can provide the circulation needed to keep diseases and insects at bay.
While the information above offers good rules of thumb (a green thumb!), keep in mind that different types of orchids have different requirements. To learn how to care for specific orchid varieties, visit our common orchid varieties page for more details.
