Bigleaf hydrangeas are perhaps the most well-known type of hydrangea. They are known for their large, round blooms and are often seen in shades of blue, pink, or purple.

 

Oakleaf hydrangeas have unique leaves that resemble oak leaves and produce cone-shaped clusters of white flowers. Smooth hydrangeas have large, round blooms that are typically white or pink.

 

Panicle hydrangeas have cone-shaped clusters of flowers that start off white and turn pink as they mature. Climbing hydrangeas are a climbing vine that produce white flowers.

 

When it comes to pruning hydrangeas for winter, it is important to understand the specific type of hydrangea you have. Bigleaf hydrangeas, for example, should not be pruned in the fall as it can damage the new growth that will produce blooms in the spring.

Instead, wait until the summer to prune them after they have finished blooming. Oakleaf hydrangeas should be pruned in the summer as well, while smooth and panicle hydrangeas can be pruned in the fall or early spring.

 

In general, hydrangeas do not require much winter care. However, it is important to keep an eye on them during the winter months to make sure they are not damaged by harsh weather conditions.

 

If you live in an area with severe winters, you may want to consider covering your hydrangeas with burlap or another protective material to keep them safe from the elements.

Hydrangea Blooming Patterns

 

Hydrangeas are known for their beautiful blooms, but did you know that the timing of their blooms can vary depending on the species? Understanding the blooming patterns of hydrangeas is important when deciding whether or not to cut them back for winter.

 

Color Variations of Blooms

 

One of the most fascinating aspects of hydrangeas is the ability of some species to change color based on the pH level of the soil. For example, a blue hydrangea can turn pink if the soil becomes more alkaline. However, this color change is not related to the blooming pattern of the plant.

Blooms and the Growing Season

 

Hydrangeas can bloom on either old wood or new wood, which refers to the previous year’s growth versus the current year’s growth. Knowing which type of wood your hydrangea blooms on is important when deciding whether or not to cut it back for winter.

 

Hydrangeas that bloom on old wood, such as the ‘Endless Summer’ variety, produce flower buds in the fall and winter that will bloom in the summer. These types of hydrangeas should not be cut back in the fall or winter, as it will remove the flower buds and prevent blooming in the summer.

 

Hydrangeas that bloom on new wood, such as the ‘Annabelle’ variety, produce flower buds in the spring that will bloom in the summer. These types of hydrangeas can be cut back in the fall or winter without affecting their ability to bloom in the summer.

Pruning Hydrangeas

 

If you want to keep your hydrangeas healthy and looking their best, pruning is an essential task. Pruning helps to remove dead branches and spent blooms, which can help promote new growth and encourage your hydrangeas to produce more flowers. However, it’s important to know when and how to prune your hydrangeas to avoid damaging the plant.

 

Pruning Different Types of Hydrangeas

 

Different types of hydrangeas require different pruning techniques. For example, hydrangeas that bloom on old growth, such as bigleaf hydrangeas, should be pruned immediately after their flowers have faded. This will help to promote new growth and ensure that your hydrangea produces plenty of blooms the following year.

 

On the other hand, hydrangeas that bloom on new growth, such as panicle hydrangeas, should be pruned in the late winter or early spring just before the critical new growth has started. This will maximize the amount of new growth and the number of flowers your shrub produces.

 

Pruning and Hydrangea Health

 

Pruning is not only important for the appearance of your hydrangeas, but it can also help keep them healthy. Removing dead branches and stems can prevent the spread of disease and pests, which can quickly take hold in a weakened plant.
