Most orchids thrive in a warm environment. To encourage bloom, provide a drop of about 10 degrees at night, especially in autumn and winter. The temperature should not fall below 55 degrees at night, with the ideal average being 60-65 degrees. The daytime temperature can go as high as 95 degrees, with 75-80 degrees being the ideal. Over 80 degrees gets dicey, calling for special ventilation and humidity.
Nothing kills orchids faster than sitting in a pool of water.
Water orchids early in the day, so the roots are dry at night. In average conditions, a 6-inch pot would need watering about once a week. If leaf tips turn brown, cut back on fertilizer. It is better to feed more often with a weak solution. Flush occasionally with plain water to prevent salt buildup.
