Oakleaf hydrangeas are a type of deciduous shrub that is known for its large, showy flower clusters. While these shrubs are relatively lowmaintenance, they do require some pruning in order to keep them looking their best. Now that the summer is in full swing, it’s time to prune oakleaf hydrangeas!

Here are some tips on how to prune oakleaf hydrangeas:

1. The best time to prune oakleaf hydrangeas is after flowering stops in late summer, but a light trim at any time of the year is good! This will help keep your hydrangeas looking neat and tidy.

2. Start by removing any dead, diseased, or damaged branches. You can do this any time of the year as soon as you notice damaged branches. Broken branches can allow diseases to enter the plant, weakening the overall system of your hydrangea. 

3. Next, thin out the shrub by removing any overcrowded or crossing branches. When the branching structure starts to cross, it crowds the flowers, and when they get larger they’ll start to rub up against one another and bruise. Simply pick which brand you want to keep, new growth or older growth. Pay attention to the direction of growth, and don’t cut too flush with the plant. Removing crossing branches opens up the structure of the plant and allows airflow to enter.

4. A harsh pruning isn’t necessary for oakleaf hydrangeas. Simply keeping their branches neat and tidy and removing dead branches will go a long way for the health of your plant.

Pro tip: always use clean, sharp pruning shears when pruning oakleaf hydrangeas. By following these tips, you can keep your oakleaf hydrangeas looking neat and tidy.

With a little bit of care, they will continue to produce beautiful flower clusters for many years to come. To learn how to choose the right hydrangea, read our blog here!
