Plant orchids seeds in a small to medium sized pot in a mixture of potting soil, bark and perlite. Potting soil alone produces an environment that is too dense for orchid seeds to properly germinate and grow. The porous nature of the bark and perlite mixture provides the soft-soiled environment in which orchids thrive.
Place the pot outside or inside the home in an area with regular, indirect sunlight. Common indoor areas include tables and desks near windows. Outdoor areas include porches with an awning. Direct sunlight may not prevent the germination process, but it does adversely affect the orchid's ability to grow to its full potential.
Water the orchid thoroughly each morning. With a watering pot or a sink faucet, slowly run water around the pot until you drench the soil. Allow the excess water to drain from the pot, and place the orchid back in its designated area.
Add water-soluble fertilizer to the soil at least once a week to ensure that the soil remains fertilized with the proper nutrients for germination.
Point a house fan at the orchid and put it on a low setting. Orchids need constant air circulation for germination and growth. A ceiling fan also works. If you are trying to germinate the orchid outdoors, the open air environment usually provides enough circulation without any additional work on your part.
Keep the temperature around the orchid between 60 and 85 degrees Fahrenheit for the best germination results. Use an outdoor or indoor thermometer to measure temperatures throughout the day and to determine the best location for your orchid.
