| The only important consideration when pruning hydrangeas is to remember that they bloom on shoots produced on old wood. So, if you cut your shrub all the way to the ground, you'll sacrifice next year's blooms. You can cut some of the old stems all the way back, and cut only one-half or one-third off of others, and you're sure to get flowers next year. In order to keep hydrangea's looking neat and trim, prune them lightly each year, cutting back all of the stems that have flowered, and leaving the others. That way, the shrub will constantly renew itself, and you'll always have flowers. |
