How Cold Can Hydrangeas Get

Fact Checked By | Post Updated On:

Hydrangeas are a type of flower that can withstand colder temperatures than most other flowers. They can tolerate temperatures as low as -30 degrees Fahrenheit. This makes them a good choice for gardeners who live in colder climates.

Hydrangeas are also relatively easy to care for, and they require little maintenance.

The hydrangea is a tough plant that can withstand a wide range of temperatures, but there is a limit to how cold they can tolerate. In general, hydrangeas can withstand temperatures as low as -30 degrees Fahrenheit, but they may suffer damage at lower temperatures. If the temperature drops below -30 degrees, the plant will start to experience frost damage.

The leaves and flowers will turn brown and wilt, and the plant may die.

Protecting Hydrangeas for Winter

Do you need to cover hydrangeas for frost?

Hydrangeas are one of the most popular flowers in the world. They are loved for their large, showy blooms and their ability to thrive in a variety of climates. However, hydrangeas are not immune to frost damage.

If you live in an area that experiences freezing temperatures, it is important to take steps to protect your hydrangeas from the cold. There are a few different ways that you can cover hydrangeas for frost protection. One option is to use a frost cloth or tarp.

This will create a barrier between the cold air and the plants. Another option is to use a light bulb to create a mini greenhouse effect. Simply place a light bulb near the plants and cover the area with a frost cloth or tarp.

The heat from the light bulb will help to keep the plants warm. If you cannot cover your plants, there are still a few things that you can do to help them survive the cold. One option is to water the plants deeply before the frost hits.

This will help to insulate the roots from the cold. Another option is to mulch around the plants. This will also help to insulate the roots and keep the plants warm.

No matter what method you use to protect your hydrangeas from frost, it is important to keep an eye on the plants. Frost can cause damage quickly, so it is important to check on the plants regularly. If you see any signs of damage, take steps to protect the plants immediately.

With a little bit of care, your hydrangeas will be able to withstand the cold and continue to thrive.

Should I cover my hydrangeas for a spring freeze?

If you’re wondering whether or not to cover your hydrangeas for a spring freeze, the answer is yes! Here’s why. Hydrangeas are delicate flowers that can be easily damaged by frost or freezing temperatures.

Even a light frost can cause the flowers to brown and wilt, so it’s important to protect them from the cold if there’s a chance of freezing temperatures. The best way to protect your hydrangeas is to cover them with a frost blanket or tarp. This will create a barrier between the cold air and the plants, and will help to keep them warm.

Make sure to secure the tarp or frost blanket so that it doesn’t blow away in the wind. If you can’t cover your plants, you can also try to water them before a freeze hits. This will help to insulate the plants and keep them from freezing.

Just be sure to not water them too close to the freezing point, as this can actually cause the plants to freeze. With a little preparation, you can keep your hydrangeas looking beautiful all spring long – even if there’s a little freeze!

Can hydrangeas withstand a freeze?

Depending on the variety, hydrangeas can withstand temperatures as low as -30 degrees Fahrenheit. However, the plant’s foliage is usually damaged by frost and will need to be pruned back in the spring.

Can hydrangeas survive winter in pots

Hydrangeas are a popular choice for gardens and landscaping because of their showy flowers and ability to thrive in many different climates. One common question about hydrangeas is whether or not they can survive winter in pots. The answer is yes, hydrangeas can survive winter in pots, but there are a few things you need to do to prepare them.

First, choose a pot that is large enough to accommodate the roots of your hydrangea. Be sure to use a pot with drainage holes to prevent the roots from sitting in water. Next, fill the pot with a high-quality potting mix and water well.

Place the pot in a location that receives indirect sunlight and protect it from windy conditions. Once the weather begins to cool, stop watering your hydrangea and allow the soil to dry out. This will help to prevent the roots from rot.

When the temperature drops below freezing, move the pot indoors or wrap it in burlap to insulate the roots. With a little care, your hydrangea can survive winter in a pot and provide you with beautiful blooms next spring.

Is 40 degrees too cold for hydrangeas

If you’re thinking of planting hydrangeas, you might be wondering if 40 degrees is too cold for them. The answer is, it depends. Hydrangeas are native to Asia and North America, so they’re used to a wide range of climates.

However, the most common type of hydrangea, the bigleaf hydrangea (Hydrangea macrophylla), is not cold hardy below Zone 6. That means that if you live in an area that gets colder than -10 degrees Fahrenheit in the winter, your hydrangeas will probably not survive the winter. There are, however, some varieties of hydrangea that are more cold hardy, such as the Oakleaf hydrangea (Hydrangea quercifolia) and the Panicle hydrangea (Hydrangea paniculata).

These varieties can tolerate colder temperatures, down to -20 degrees Fahrenheit or even colder in some cases. So if you live in a colder climate and you’re determined to grow hydrangeas, you may want to look into these more cold-hardy varieties. Of course, even if you live in a cold climate, there are ways to protect your hydrangeas from the cold.

One option is to plant them in a sheltered spot, such as against a south-facing wall. You can also mulch around the base of the plant to help insulate it. And if you’re really worried about the cold, you can always bring your potted hydrangeas indoors for the winter.

So if you’re wondering if 40 degrees is too cold for hydrangeas, the answer is maybe, but it depends on the variety and how you protect them.

How cold can potted hydrangeas tolerate

If you live in a climate where the temperature routinely dips below freezing in the winter, you’ll need to take some extra steps to protect your potted hydrangeas. These delicate flowers are native to tropical and subtropical regions and can’t tolerate cold temperatures for long. When the mercury starts to drop, move your potted hydrangeas indoors to a cool, sunny spot.

If possible, keep them near a south-facing window where they’ll get plenty of light. Once they’re indoors, stop watering them as often. Allow the soil to dry out slightly between watering.

In very cold weather, you may need to give your potted hydrangeas a little extra protection. Place them in a cool room or basement where the temperature won’t dip below freezing. You can also wrap the pots in burlap or bubble wrap to insulate them further.

With a little extra care, your potted hydrangeas will survive the winter and bloom beautifully come spring.


Hydrangeas are one of the most popular garden plants, but many people don’t realize how cold-sensitive they can be. The plant’s roots are particularly vulnerable to freezing temperatures, so it’s important to protect them during the winter months. There are a few different ways to do this, including covering the plant with mulch or a frost cloth.

If the temperatures are expected to dip below freezing, you may also want to bring the plant indoors to prevent it from being damaged by the cold.
