How to Overwinter Hydrangeas in Pots

Hydrangeas are a beautiful addition to any garden and are easy to grow in containers. However, while they are easy to grow, it can be a bit tricky to overwinter them outdoors in cold climates. Here are a few tips and tricks to help you get your potted hydrangeas through the winter:

1. Choose Hardy Varieties

When choosing hydrangeas to overwinter in a pot, it’s important to pick varieties that are hardy in your climate Zone. Most hydrangeas are hardy in Zones 5-9, but you need to make sure of the variety you have, as some are hardier than others.

2. Prune to the Ground

When hydrangeas go dormant in the fall, it’s a good idea to prune them to the ground to help protect them from the cold. This will help keep the roots warmer and reduce the chances of the plant being damaged.

3. Provide Protection

During the cold winter months, you’ll need to provide extra protection for your hydrangeas in pots. Wrapping the container in bubble wrap or burlap can provide some additional insulation and protection from the cold.

4. Bring the Pot Indoors

One of the best ways to overwinter hydrangeas in pots is to bring them indoors during the coldest months. If you have a greenhouse or a sunroom, this is a great way to ensure that your plants stay safe from the cold weather.

5. Add Mulch

Adding a layer of mulch to the pot can help provide insulation for the roots of your hydrangea in cold weather. Be sure to use an organic mulch such as wood chips or straw, and avoid using plastic or rubber sheeting that can retain cold temperatures for too long.

6. Check for Water

You’ll want to make sure that you check the soil of your potted hydrangea regularly to ensure it has enough water. Hydrangeas are prone to drying out during the winter should the soil get too dry. Keeping the soil moist will help your plant make it through the cold months.

7. Fertilize in the Spring

When the temperature starts to warm up in the spring, it’s a good idea to fertilize your hydrangea to help it come out of dormancy. After fertilizing, the new growth should start to appear and your plant will be ready to go for the new season.


By following these simple tips and tricks, you’ll be able to overwinter your potted hydrangeas with ease. Hydrangeas are an easy and beautiful addition to any garden, and with the right care they can thrive through the winter months.
