The ideal temperature to cover your hydrangeas is between 50-70 degrees Fahrenheit. Anything below 50 degrees will cause the plant to go dormant, and anything above 70 degrees will cause the flowers to wilt.

Protecting Hydrangeas for Winter
If you’re wondering what temperature you should cover your hydrangeas, the answer is simple: it depends on the plant. Some plants are more cold-hardy than others, so it’s important to know your plant’s specific needs. However, as a general rule of thumb, you should cover your hydrangeas when the temperature drops below 50 degrees Fahrenheit.
This will protect the plants from frost damage and help them stay healthy all winter long.
Do I Need to Cover My Hydrangeas for Frost
. . and When?
Hydrangeas are a beautiful addition to any garden, but they can be delicate in cold weather.
If you live in an area with frost or snow, you may be wondering if you need to cover your hydrangeas for protection.
The good news is that hydrangeas are generally hardy plants and can withstand some cold weather. However, if the temperatures are expected to dip below freezing, it’s a good idea to take some precautions.
One option is to simply move your potted hydrangeas indoors during the colder months. If you have space in a sunny spot near a window, they should do well indoors until it’s time to put them back outside in the spring.
Another option is to build a simple frame around your hydrangea bush and cover it with burlap or another breathable fabric.
This will help protect the plant from the cold and wind while still allowing air circulation.
If you’re not sure whether or not to cover your hydrangeas, err on the side of caution and give them some protection from the cold weather. With a little care, they’ll bounce back in no time once spring arrives!
When to Cover Hydrangeas for Winter
When to Cover Hydrangeas for Winter It’s that time of year again when the days are getting shorter and the temperatures are starting to drop. That means it’s time to start thinking about protecting your plants from the cold winter weather.
Can I Leave My Potted Hydrangea Outside
It’s no secret that hydrangeas are one of the most popular flowering shrubs around. They come in a variety of colors and their big, bold blooms are sure to make a statement in any garden. But what about growing hydrangeas in pots?
Can you leave your potted hydrangea outside, or should you bring it inside when the weather gets cold?
Here’s what you need to know about growing hydrangeas in pots:
Hydrangeas are native to temperate climates and can tolerate a wide range of temperatures.
However, they will not survive if exposed to freezing temperatures for extended periods of time. If you live in an area where the winters are particularly harsh, it’s best to bring your potted hydrangea inside when the temperature starts to drop.
When it comes to watering, potted hydrangeas will need more water than those that are planted directly in the ground.
This is because the roots are confined to a smaller space and have less access to moisture. Be sure to check the soil regularly and water as needed – usually every few days – during the warmer months. In cooler weather, you can reduce watering somewhat but be sure not to let the soil dry out completely.
Potted hydrangeas also need regular fertilizing throughout the growing season. A balanced fertilizer applied monthly should suffice. Just be sure not to over-fertilize as this can damage the roots and lead to leaf burn.
When Can I Put My Potted Hydrangea Outside
When the weather outside is warm and sunny, you may be wondering when you can put your potted hydrangea outside. The answer depends on a few factors, such as the type of hydrant you have and the climate in your area.
If you have a mophead or lacecap hydrangea, it is best to wait until after the last frost date in your area before putting it outside.
These types of hydrangeas are not cold hardy and can be damaged by frost.
If you have a panicle or smooth hydrangea, you can put it outside earlier since these varieties are more cold hardy. However, if there is still a chance of frost in your area, it is best to wait until after the last frost date to put them out.
In general, it is best to wait until springtime to put your potted hydrant outside permanently. This will give the plant time to adjust to its new environment and get acclimated to the temperature changes.
Potted Hydrangea Winter Care
If you’re like most gardeners, you’re probably itching to get outside and start planting now that spring is here. But before you do, there are a few things you need to know about how to care for your potted hydrangeas during the winter months.
Hydrangeas are a popular choice for container gardening because they are relatively low-maintenance and can add a pop of color to any patio or deck.
However, they are not immune to the cold weather and need some extra care during the winter months.
Here are a few tips on how to care for your potted hydrangeas during the winter:
1. Bring them inside – The first step is to bring your potted hydrangeas inside before the temperatures start to drop too low.
You’ll want to find a spot that gets plenty of indirect sunlight, such as a south-facing windowsill.
2. Water less often – During the winter months, your plants will need less water than they do during the warmer months. Allow the soil to dry out somewhat between watering sessions, and don’t be tempted to over-water in an effort to keep them alive.
Too much water can actually kill your plants!
3. Prune them back – Once the blooming season is over, it’s time to prune your plants back by about one-third their overall size. This will help encourage new growth in the springtime.

When Should You Cover Your Hydrangeas?
It’s that time of year again when the temperatures start to drop and we need to start thinking about protecting our plants from the cold weather. One question we get a lot at the nursery is “When should I cover my hydrangeas?”
The answer to this question depends on what type of hydrangea you have.
There are two main types of hydrangeas – paniculata and macrophylla. Paniculata varieties, such as ‘Limelight’ and ‘PeeGee’, are much more tolerant of cold weather and don’t need to be covered. Macrophylla varieties, on the other hand, such as ‘Annabelle’ and ‘Mophead’, are not as hardy and will benefit from being covered in frosty weather.
If you’re not sure which type of hydrangea you have, a good rule of thumb is to cover them if they’re blooming or if they have new growth. This will help protect the delicate flowers and buds from frost damage. To cover your plant, simply drape a sheet or cloth over it, making sure it touches the ground all around so that no cold air can get in.

What Temperature Will Damage Hydrangeas?
Hydrangeas are a type of flower that is native to Asia and North America. They are usually found in shades of pink, blue, or purple, but can also be white. The flowers have a large center cone surrounded by four to five smaller petals.
Hydrangeas require moist soil and partial sun to thrive.
While hydrangeas are fairly hardy flowers, they can be damaged by extreme temperatures. If the temperature drops below -30 degrees Fahrenheit (-34 degrees Celsius), the flowers will freeze and turn brown.
If it gets too hot – over 100 degrees Fahrenheit (38 degrees Celsius) – the flowers will wilt and turn brown at the tips. In both cases, the leaves will also be affected; they may curl up or drop off entirely.
To protect your hydrangeas from damage, it’s important to choose a planting location carefully.
Avoid areas that are subject to strong winds or direct sunlight for long periods of time. You should also mulch around the plants to help insulate them from extreme temperatures swings. And finally, make sure you water them regularly; wilting due to heat stress is often caused by dehydration rather than high temperatures alone.
How Cold Can Hydrangeas Handle?
Hydrangeas are a hardy plant that can withstand cold temperatures. They can handle frost and snow, but they will not do well in freezing temperatures. If the temperature drops below freezing, the flowers and leaves will turn black and die.
The roots will also be damaged and may not be able to regrow the plant.
Will My Hydrangeas Survive a Frost?
If you live in an area where the temperature drops below freezing, your hydrangeas may be at risk of damage from frost. While most varieties of hydrangea are fairly tolerant of cold weather, their flowers are not. If the flowers are exposed to frost, they will turn brown and wilt.
The leaves may also suffer damage, but they will usually recover once the temperatures warm up again.
If you want to protect your hydrangeas from frost damage, you can take a few measures. First, choose a variety that is known to be more resistant to cold weather.
Second, plant them in an area that is sheltered from the wind. Third, Mulch around the plants to help insulate them. And finally, if possible, bring them indoors or into a garage during especially cold nights.
With a little care and attention, your hydrangeas should be able to survive even the harshest winters!
Conclusion
If you’re wondering what temperature you should cover your hydrangeas at night, the answer is probably lower than you think. Most people believe that they need to protect their plants from freezing temperatures, but this is actually not the case for most hydrangeas. In fact, covering them up can actually do more harm than good.
When it comes to protecting your plants from the cold, it’s important to remember that the goal is to keep them from getting too cold, not necessarily to keep them warm. If you cover your hydrangeas with a blanket or tarp at night, they may actually end up getting too warm, which can damage the flowers.
The best way to protect your hydrangeas from the cold is to water them well before the first frost and then let them go dormant for the winter.
This means stopping all fertilizer and watering until spring arrives. Once the danger of frost has passed, you can start fertilizing and watering again and enjoy beautiful blooms all summer long.
