| Which is the best fertilizer for hydrangeas? Miracid or MiracleGro bloom booster(15-30-15)? |
| Either Miracid or Miracle-Gro will work for your hydrangea. Both are slightly acidified which will result in blue flowers and the N-P-K ratio of 15-30-15 is high in phosphorous which will encourage flowering. Best wishes with your hydrangeas! |
