Phalaenopsis Post-Bloom Care: Watering, Fertilizer, and Spike Management

After the Flowers Fall

Your white Phalaenopsis with purple center bloomed since December. Now flowers are gone, leaves are healthy, a new leaf is emerging—but the pot stays wet a week after watering.

Critical Watering Correction

Stop watering on a schedule. Phalaenopsis need the mix to become almost dry between waterings. Constant wetness rots roots. Check with a bamboo skewer—if it feels moist, wait.

• Ensure pot has drainage holes.
• Water thoroughly in morning, let drain completely.
• Frequency varies by season, mix, humidity—typically 7–10 days.

Fertilizer Advice

• Better-Gro at ½ label strength is acceptable short-term.
• Switch to a balanced orchid fertilizer (e.g., 20-20-20) at ¼ strength weekly when new growth appears.

Spike Management

Cut the spent spike 1–2 inches above the base. Some hybrids rebloom from nodes, but most benefit from a full rest.
