As the temperatures begin to drop and winter approaches, it is important to prepare your hydrangea plants for the cold weather. Winterizing your hydrangeas will ensure that they survive the winter and come back strong and healthy in the spring. In this article, we will discuss some tips and tricks for winterizing your hydrangea plants.

Understanding Your Hydrangeas

Before we dive into the winterizing process, it is important to understand the different types of hydrangeas and their specific needs. There are six main types of hydrangeas: mophead, lacecap, oakleaf, panicle, smooth, and climbing. Each type has its own unique characteristics and requirements. It is important to identify which type of hydrangea you have in order to properly care for it.


If you are unsure about the type of hydrangea you have, consult a gardening expert or do some research to identify it.

Preparing Your Hydrangeas for Winter

The first step in winterizing your hydrangea plants is to prepare them for the cold weather. This involves removing any dead or diseased branches, cleaning up fallen leaves, and adding a layer of mulch around the base of the plant. Mulch will help insulate the roots and protect them from the cold.


When adding mulch, be careful not to cover the base of the plant or the stems, as this can lead to rotting.

Protecting Your Hydrangeas from the Cold

Once your hydrangeas are prepared for winter, it is important to protect them from the cold temperatures. This can be done using burlap or frost blankets to cover the plants. Be sure to wrap the plants loosely so that they have room to breathe and do not become damaged.


If you live in an area with heavy snowfall, it is important to shake off any excess snow from the branches of your hydrangeas to prevent them from breaking.

Watering Your Hydrangeas in Winter

During the winter months, it is important to keep your hydrangeas properly hydrated. While you do not need to water them as frequently as you would in the summer, it is important to check the soil regularly to ensure that it is not too dry. Watering your hydrangeas in the winter will help prevent the roots from drying out and becoming damaged.


Be sure to water your hydrangeas during the daytime when the temperatures are warmer to prevent the water from freezing.

Pruning Your Hydrangeas in Winter

Pruning your hydrangeas in the winter is not recommended, as it can damage the plant and prevent it from blooming in the spring. Instead, wait until the spring to prune your hydrangeas, when the new growth has begun to appear.


If you must prune your hydrangeas in the winter, be sure to only remove dead or damaged branches, and avoid cutting into healthy wood.


Winterizing your hydrangea plants is an important step in ensuring their health and longevity. By following these tips and tricks, you can help protect your hydrangeas from the cold temperatures and ensure that they come back strong and healthy in the spring. Remember to identify the type of hydrangea you have, prepare the plant for winter, protect it from the cold, water it properly, and avoid pruning it until the spring. With a little bit of care and attention, your hydrangeas will thrive year after year.
