Phalaenopsis Orchid Care: The Beginner's Guide to Moth Orchids

Phalaenopsis—"moth orchids"—are the most popular orchids for good reason: they're forgiving, widely available, and bloom for months. With basic attention to light, water, and humidity, anyone can grow them successfully.

Light: Bright, Indirect, or Artificial

East or south-facing windows (sheer curtain diffused) are ideal. No direct afternoon sun—it scorches leaves. If natural light is insufficient, fluorescent or LED grow lights work beautifully. Keep plants 12–24 inches from the source.

Water: Thorough, Then Dry

Water when the bark mix is nearly dry—usually every 7–10 days. Soak the pot thoroughly; let drain completely. Never let roots sit in standing water. In winter, stretch to 10–14 days. Morning watering lets foliage dry by night, preventing rot.

Humidity: 40–60%

Homes are often drier. Use a humidity tray: pebbles in a shallow tray with water (pot sits above water line). Group plants to create a microclimate. Avoid misting leaves—it invites fungal spots.

Potting & Repotting

Use orchid bark mix in a clear plastic pot with drainage holes. Repot every 1–2 years after blooming, when new roots emerge. Trim dead roots (brown/mushy); keep firm, white/green ones.

Fertilize Weakly, Weekly

Use balanced orchid fertilizer at ¼ strength weekly during growth. Flush with plain water monthly to prevent salt buildup.

With these habits, your Phalaenopsis will reward you with elegant blooms year after year.
