Orchids That Can Only Bloom in One Place

Moving Orchids

• If your orchid regularly flowers, avoid moving it. If a move is unavoidable, duplicate its conditions as much as possible. Measure the temperature and light intensity. Provide the same humidity levels and air circulation in the new location. Understanding your orchid’s exact requirements help to make it flower again.

Light

• Orchids flower when kept in bright, indirect sunlight and at the right nighttime temperature. Orchids are grouped into cool-, intermediate- and warm-temperature types, according to the University of Vermont's Leonard Perry, Ph.D. These require night temperatures of 45 to 50 degrees Fahrenheit, 55 to 65 F, and above 65 F respectively. Orchids flower when day temperatures are 15 to 20 degrees above night temperatures.

Light Levels

• Orchids thrive in bright, indirect sunlight and do not flower in low-light conditions. An east-facing or shaded west- or south-facing windowsill is the ideal location for indoor orchids.

Water

• Water your orchid when its growing medium is almost completely dry. Soak it thoroughly and allow all excess water to drain. Never leave orchids standing in water, as their roots die and rot. Placing your orchid on a dish of damp gravel raises local humidity levels. Misting the leaves keeps them clean and discourages spider mites. Use rainwater or low-mineral bottled water for orchids, as salts and other minerals damage them.

Other Factors

• Using a low-powered electric fan provides air circulation. Fertilize your orchids regularly with a liquid formulated for orchids. A high-phosphorus fertilizer during the autumn encourages flowering. Protect orchids during moves, as cold shock damages leaves and causes bud drop.

Flower Problems

• If your orchid develops but then sheds flower buds, move it away from the fruit bowl, as the ethylene gas from ripe fruit causes bud drop.
