Orchids like a day temperature of about 70F during the summer and 60F during the winter, with a 10 degree drop at night. Cool nights are important to the health and flowering ability of your plant. Orchids require 10-15 hours of light each day, so you may need to supplement natural light with artificial light during the winter months when the days are short. Orchids like moist soil and appreciate being misted once or twice each day. To increase humidity around the plant, place the pot on a layer of rocks in a tray of water. As the water evaporates it will provide moist, humid conditions around your plant. Orchids bloom best when slightly rootbound so they will need repotting only every 3-4 years. When it's time, choose a container just slightly larger than the one it is growing in. Fill the container part way with a bark nugget based orchid mix potting soil and set the roots of your orchid in the pot, then fill around with additional potting mix. Following the above advice should result in lovely blooms on your orchids!
