Introduction to Orchids
Orchids are the largest family of flowering plants on Earth, with over 25,000 species found on every continent except Antarctica. As houseplants, the Phalaenopsis (Moth Orchid) is by far the most popular and widely grown, prized for its elegant, long-lasting blooms in virtually every color of the rainbow and its surprisingly easy care requirements. Native to the tropical forests of Southeast Asia, Phalaenopsis orchids are epiphytic — they grow on trees rather than in soil — which means their care requirements are quite different from typical houseplants. Once you understand their unique needs, orchids are incredibly rewarding and can bloom for months at a time.
Light Requirements
Phalaenopsis orchids thrive in bright, indirect light. They cannot tolerate direct sunlight, which scorches their leaves and flowers. An east- or west-facing window is ideal. A good indicator of correct light: the leaves should be bright, medium green — dark green indicates too little light, yellowish-green indicates too much. Adequate light is essential for reblooming.
Watering
Water your orchid once a week by thoroughly soaking the roots and allowing excess water to drain completely. Never let the orchid sit in standing water, which causes root rot. The roots should be bright green when wet and silvery-green when dry — water when the roots begin to look silvery. Use room-temperature water and avoid getting water in the crown (center) of the plant, which causes crown rot.
Humidity & Temperature
Phalaenopsis orchids prefer temperatures between 65–85°F (18–29°C) during the day and slightly cooler at night (55–65°F). They love moderate to high humidity (50–70%). A pebble tray with water placed beneath the pot (without the pot touching the water) is an excellent way to increase humidity without risking root rot.
Potting Medium
Orchids should never be planted in regular potting soil. Use a specialized orchid bark mix that provides excellent drainage and aeration around the roots. Repot every 1–2 years in spring when the bark begins to break down or the roots outgrow the pot. Clear plastic pots are ideal as they allow you to monitor root health.
Fertilizing
Feed weekly with a diluted orchid fertilizer (quarter strength) during the growing season, or use the 'weakly, weekly' approach. Reduce fertilizing after blooming. Flush the pot with plain water monthly to prevent salt buildup.
Encouraging Reblooming
After the blooms fade, cut the flower spike just above a node (the small bump on the stem). With the right conditions, a new spike will emerge from this node. The key to reblooming is a temperature drop of 10–15°F at night for 4–6 weeks in fall — this temperature differential triggers new spike formation. Consistent bright light and regular fertilizing also help.

Common Problems & Solutions
Yellow leaves: Overwatering or too much direct light — reduce watering and move to indirect light. No reblooming: Insufficient light or no temperature drop — increase light and provide a cool night period in fall. Root rot (brown, mushy roots): Overwatering — remove affected roots and repot in fresh bark. Wrinkled leaves: Underwatering — water more frequently.
