Orchids Not Blooming After 3 Years: Fertilizer Switch and Epsom Salts

Fertilizer Problem

All-purpose high-nitrogen fertilizer (e.g., Miracle-Gro 24-8-16) promotes leaves, not flowers. Year-round use suppresses blooming.

Bloom-Inducing Strategy

1. Late summer/fall: switch to low-nitrogen, high-phosphorus fertilizer (e.g., 10-30-20).
2. OR stop fertilizing in winter; water only.
3. Add Epsom salts (1 tsp/quart) 3× over 3 weeks in fall—magnesium triggers bloom cycle.

Other Factors

• Light: some need full sun, some deep shade—ID needed.
• Temp: some need cool nights.
• Repot annually in fresh bark.
