Why is my hydrangea not blooming?

I always recommend that hydrangea gardeners start with the right fertilizer to get the most blooms. Set Yourself up for Blooming Success is a great place to begin to learn about selecting the right fertilizer and knowing when to fertilize. Avoid fertilizers that are high in nitrogen as they will help your hydrangea grow numerous branches and leaves at the expense of flowers. Then, learn about pruning hydrangeas. Prune at the wrong time and you risk cutting off the flower buds. Our planting and care guide has advice on when and how to prune plus other tips for growing healthy hydrangeas.
