Do Potted Orchids Come Back?

Sunlight

• Most orchid species thrive under tree canopies in nature; they are not subjected to direct sunlight. Place your potted orchid about 3 feet away from a west- or south-facing window. Using thin curtains to filter the sunlight, your orchid uses the indirect rays to photosynthesize without heat stress. Excessive sunlight bleaches the foliage as plant cells die back; chlorophyll fails and leaves appear yellow or cream-colored. Darkened locations, in contrast, force orchids to produce more chlorophyll to compensate for reduced sunlight exposure. Light green leaves turn deep green as orchids struggle during energy production.

Temperature

• Depending on the variety, orchids respond to temperature fluctuations between night and day by signaling a new blooming period. For example, indoor winter temperatures should drop to approximately 60 or 62 degrees Fahrenheit at night while daytime reflects a temperature of 70 to 80 degrees Fahrenheit for the best blossoming trigger. As days pass with these fluctuations, flower spikes form and buds slowly emerge. Enhance temperature fluctuations with water trays under your potted orchid as well. Without setting the plant directly in the water, spread gravel in a water tray and place the pot on the rocks. Water evaporates around the orchid to increase humidity as flowers develop.

Watering

• If you can see your potted orchid's roots, like in a transparent container, they should appear white with green tips as they enter an active growing period. Your medium is typically sphagnum peat moss or fir bark. In general, water peat moss medium every two weeks compared to bark that requires weekly irrigation. Only water when the medium is truly dry to a half-inch depth to avoid rot and soggy conditions. Apply rainwater or distilled water to your orchids for the best growing results; high-mineral tap water often stunts orchid growth. Although winter growth is minimal, requiring little water, your potted orchid's return to a flowering state needs ample moisture to support the blossoms.

Repotting

• Do not immediately repot your orchid to encourage its return. Although they may seem root-bound, orchids prefer a snug root environment. After about two years, repot your orchid with fresh medium. You can use a slightly larger pot if growth has been vigorous, but the main reason for repotting is medium decay. Both peat moss and bark break down over time; your orchid cannot thrive in a potting soil habitat as large particles become smaller.
