The miniature Phalaenopsis orchid is a hybrid variety created to produce small flowers in cooler temperatures. Miniature Phalaenopsis orchids bloom in the fall and spring by producing spikes with many flowers lasting about two months. To produce flowers, this type of orchid requires a night temperature of 55 degrees F for several weeks and a daytime temperature of 75 to 85 degrees F. Warmer temperatures and bright light will force more vegetative growth in the plant.
Plant the miniature Phalaenopsis orchid in a porous mixture of a medium grade orchid potting mix. Place a handful of potting mix into the bottom of the container and gently spread the roots over top. Fill the container with potting mix and gently firm the mix around the stem and roots to hold in place.
Place the orchid in an east window offering low to medium light conditions or a shaded south or west window. Artificial lighting may be needed in areas where winters are predominantly overcast. Place the lighting 6 to 12 inches above the plants for 12 to 16 hours per day.
Provide a humid environment around the orchid plants at a minimum of 50 percent humidity. Increase humidity around the plant by filling a tray with stones or gravel and adding water. Place the plant on top of the stones so it doesn't sit directly in water.
Water the miniature Phalaenopsis orchid once the potting mix begins to dry out. Use rainwater or water with a pH lower than 7.5 as the orchid prefers slightly acidic conditions. Mist the plant at each watering to increase humidity levels.
Fertilize the orchid with a high-nitrogen orchid fertilizer twice a month when you water if you are using a potting mix that is bark based. If you have a soil-based potting mix, use a balanced fertilizer.
Repot the orchid into a larger pot once the roots begin wrapping around the inside of the pot. Orchids require repotting every two to three years. Repot the plant in the spring months after flowering is complete. Choose a pot that allows the roots to spread on the bottom and just touch the sides. Remove all potting mix from the roots, trim soft or rotted roots and repot in fresh potting mix.
