Step-by-Step Guide

Pruning should ideally occur from late February to early March when new growth begins to appear.

2. Be mindful of the local climate and adjust your timing accordingly.

Start by cutting off the old hydrangea seed heads to promote new growth.

1. Identify the seed heads on the stems.
2. Make an angled cut just above the buds located below the seed head.

Examine the plant for any dead or crossing stems that could hinder airflow.

1. Identify stems that are crossing over each other or appear dead.
2. Carefully snip off these stems to create space and airflow in the center of the plant.

To rejuvenate the plant, you should also cut back a percentage of the old growth.

1. Consider removing 10 to 20 percent of the old stems to encourage new shoots.
2. Focus on maintaining the overall shape while ensuring healthy growth.
