Hydrangea Not Blooming: Stop Miracle‑Gro, Use Miracid, Ensure Acid Soil

Three Hydrangeas, Five Years, Zero Blooms

Full sun, southern exposure, large green plants, limed soil, Miracle‑Gro every two weeks – still no flowers.

Immediate Fixes

1. Stop Miracle‑Gro – high nitrogen prevents blooming.
2. Switch to Miracid (or similar acid‑plant fertilizer) – hydrangeas need acidic soil.
3. Don’t prune until after bloom (if they ever bloom). Remove dead wood only.
4. Keep soil moist but well‑drained.

Why Lime Was Wrong

Hydrangeas are acid‑loving; lime raises pH, making nutrients unavailable. Miracid helps lower pH and provides proper nutrients.
