How to Water a Phalaenopsis: The "Barely Moist" Rule

Your new Phalaenopsis (deep purple/pink flowers, 4 blooms, 6 buds, bright green leaves) sits near a south-facing kitchen window (bright, no direct sun, blinds regulate). Humidity normal, no cooking. How to water?

Water by Mix Condition, Not Schedule

Phalaenopsis like moisture around roots but not constant wetness. Water when the potting mix becomes **barely moist**—not on a fixed day count.

• Summer (warm): every 3–7 days.
• Winter (cool): every 7–10+ days.

Ideal Conditions

• Temp: 60–85°F
• Humidity: >50%
• Light: bright indirect (east window ideal; south with blinds works)
• Air movement: occasional breeze
• Fertilizer: balanced orchid food at ¼ label strength

Bloom Trigger

Early fall: 3 weeks of 55°F nights (days >65°F) initiates spike formation.
