Are Orchids Cold Hardy
Last Updated on July 8, 2023
Orchids are a beautiful and popular type of flower, but many people don’t know that they can actually be quite hardy. Orchids can tolerate colder temperatures than most other flowers, making them ideal for growing in cooler climates. In fact, some types of orchids can even survive frost!
Orchids are a type of flower that is known for being delicate and finicky. They are often associated with warm, humid climates and tropical jungles. However, there are actually many different types of Orchids, some of which are quite hardy and can tolerate cold temperatures.
There are two main types of Orchids: terrestrial and epiphytic. Terrestrial Orchids grow in the ground, while epiphytic Orchids grow on trees or other plants. Epiphytic Orchids are generally more sensitive to the environment and need more care than terrestrial Orchids.
SomeOrchid species that are cold hardy include: Bletilla striata, Brassia arachnitiformis, Cypripedium calceolus, Dendrobium moschatum, Hardy Vanilla (Vanilla planifolia), Masdevallia Veitchiana , Miltoniopsis roezlii , Oncidium Sharry Baby ‘Sweet Fragrance’, Ophrys apifera , Sophronitis coccinea , Stanhopea oculata , Sympodiale Orchids (Bletilla striata). These varieties can withstand frost and some even survive in snow!
If you live in an area with cold winters, you can still enjoy growing Orchids!
Just be sure to choose a variety that is appropriate for your climate zone.

What Temperature is Too Cold for an Orchid?
When it comes to orchids, temperature is everything. They are tropical plants that prefer warm, humid conditions. In general, anything below 50 degrees Fahrenheit is too cold for an orchid.
However, some species can tolerate cooler temperatures better than others. For example, the Phalaenopsis orchid can withstand temperatures as low as 40 degrees Fahrenheit. On the other hand, the Cattleya orchid needs warmer conditions and will not do well in temperatures below 60 degrees Fahrenheit.
If you live in an area with cool winters, you will need to take steps to protect your orchids from the cold weather. One option is to grow them indoors under artificial lights. Another option is to use a greenhouse to create a warm, humid environment for your plants.
If neither of these options is available to you, you can try wrapping your pots in bubble wrap or burlap and placing them in a sheltered spot outdoors (such as against a south-facing wall). Just be sure to bring them back inside before the temperatures start dipping into the 50s!
Can Orchids Be Kept Outside in Winter?
It’s a common misconception that orchids can’t be kept outside in winter, but the truth is, they can! Here are a few tips to help you successfully keep your orchids outdoors during the colder months:
1. Choose a location that gets plenty of indirect sunlight.
Orchids need bright light to thrive, but direct sunlight can scorch their delicate leaves. A spot near a south-facing window is ideal.
2. Protect your plants from drafts.
Cold air coming from open windows or doors can damage your orchids, so make sure they’re not in direct line with any airflow.
3. Bring them inside if the temperature drops below 50 degrees Fahrenheit. While some species of orchids can tolerate cooler temperatures, most will start to suffer when it gets too cold.
If you see any signs of stress (such as wilting leaves), bring your plants indoors until conditions improve.
4. Water regularly, but don’t overdo it. Orchids like to have moist soil, but too much water can lead to root rot.
Stick your finger in the soil to check for moisture levels; if it feels dry an inch below the surface, it’s time to water again.
How Do You Keep Orchids Alive in the Winter?
If you’re like most orchid enthusiasts, you probably can’t wait for winter to be over so that you can get your hands on some new plants. But what about the orchids you already have? How do you keep them alive during the coldest months of the year?
The good news is that with a little extra care, your orchids can survive the winter just fine. Here are a few tips to help you out:
1. Bring them inside.
If possible, bring your orchids inside before the first frost hits. This will give them a chance to gradually adjust to lower temperatures and higher humidity levels.
2. water less frequently.
During the winter, your orchids will need less water than they do during other times of the year. Allow the potting mix to dry out completely between watering sessions, and don’t be tempted to add more water just because it’s cold outside.
3. Give them some light.
Orchids need bright light to grow well, but direct sunlight can be too much for them during the winter months. Place your plants near a south-facing window where they’ll get plenty of indirect light without being exposed to too much heat or cold drafts.
4. Keep an eye on temperature fluctuations .
One of the biggest dangers to orchids during winter is sudden changes in temperature (think: opening and closing doors). If possible, try to keep your plants in an area of your home that doesn’t fluctuate too much in temperature throughout the day and night.
Can You Keep Orchids in an Unheated Greenhouse?
Orchids are a beautiful and popular choice for houseplants, but they can be finicky. One of the main concerns with keeping orchids is providing them with the right amount of humidity. If you live in a dry climate, an unheated greenhouse can be the perfect solution for growing healthy orchids.
The key to success with growing orchids in an unheated greenhouse is to choose a variety that is suited for your climate. Some orchid varieties are more tolerant of cooler temperatures than others. Once you’ve selected a variety, make sure to provide plenty of ventilation in your greenhouse.
Good air circulation will help prevent fungal diseases and encourage healthy growth.
Another important consideration is watering. Orchids like to have evenly moist soil, but they don’t like to sit in waterlogged conditions.
Allow the top inch or so of soil to dry out between wateringings, and make sure your pots have drainage holes to prevent soggy roots. In general, it’s best to water early in the day so the leaves have time to dry before nightfall when humidity levels are higher.
With proper care, you can successfully grow healthy orchids in an unheated greenhouse!

Phalaenopsis Temperature Tolerance
Phalaenopsis are tropical plants that originated in Southeast Asia. They are used to warm weather and high humidity. When growing Phalaenopsis, it is important to maintain these same conditions in order to keep the plant healthy.
The optimum temperature range for Phalaenopsis is between 70-80 degrees Fahrenheit during the day and 60-70 degrees Fahrenheit at night. If the temperature gets too cold, the leaves of the plant will turn brown and drop off. The flowers will also be affected and may not open properly or may not last as long.
If the temperature gets too hot, the leaves will turn yellow and wilt. The flowers will also be affected and may not open properly or may not last as long.
It is important to have a consistent temperature when growing Phalaenopsis so that they can flower correctly.
If there are sudden changes in temperature, it can cause stress on the plant which can lead to bud blast (when buds fall off before they have a chance to bloom).

Phalaenopsis Temperature Range Celsius
When it comes to the temperature range that Phalaenopsis orchids can tolerate, they are actually quite versatile. In fact, they can thrive in a wide range of temperatures, as long as there is a significant difference between night and day.
Ideal daytime temperatures for Phalaenopsis orchids fall between 21-29 degrees Celsius (70-84 degrees Fahrenheit). During the night, however, these same plants prefer cooler conditions and will do best when nighttime temperatures dip down to around 16 degrees Celsius (61 degrees Fahrenheit).
It’s important to note that Phalaenopsis orchids cannot tolerate extended periods of cold weather.
If temperatures drop below 10 degrees Celsius (50 degrees Fahrenheit) for an extended period of time, these plants will likely suffer damage. For this reason, it’s important to take measures to protect your plants if you live in an area with cold winters.
Overall, as long as you provide your Phalaenopsis orchid with a temperature range that includes both warm days and cool nights, they should be happy and healthy!
Dendrobium Cold Tolerance
Dendrobium is a vast and diverse genus of orchids, many of which hail from tropical and subtropical regions where they grow epiphytically on trees. However, there are also a good number of species that come from temperate climates, and these tend to be the ones that are most popular with hobbyists in colder parts of the world. While most dendrobiums will not tolerate frosty conditions, there are a few that can take a light dusting of snow without too much trouble.
One such species is Dendrobium nobile, which originates in the Himalayan mountains. This tough little orchid can withstand temperatures as low as 5 degrees Fahrenheit (-15 degrees Celsius), making it one of the most cold-tolerant dendrobiums out there. Another option for those looking for a dendrobium that can handle some cold weather is Dendrobium densiflorum, which comes from Japan.
This plant can tolerate temperatures down to 20 degrees Fahrenheit (-6 degrees Celsius).
If you live in an area with very cold winters, your best bet might be to grow your dendrobiums in pots so that you can move them indoors when the temperature starts to drop. With proper care, these beautiful plants will thrive and provide you with years of enjoyment.
What Temperature is Too Hot for Orchids
Orchids are a very popular type of flower, and they come in a wide variety of colors. They are also relatively easy to care for, which makes them a great choice for people who want to have flowers in their home but don’t want to deal with the hassle of caring for them. However, there is one thing that you need to be careful about when it comes to orchids: the temperature.
Orchids are tropical plants, which means that they like warm temperatures. But just how warm is too warm for an orchid?
The short answer is that anything above 80 degrees Fahrenheit is too hot for an orchid.
In fact, even temperatures in the low 80s can be problematic for these delicate flowers. If the temperature gets any higher than that, your orchid will start to experience stress and may even die.
So what should you do if it starts to get too hot outside?
The first step is to move your orchid inside if possible. If it’s not possible to move it inside (for example, if you live in an apartment and don’t have any outdoor space), then you can try putting it in a cool spot such as a basement or cellar. You can also try running a fan near your orchid to help keep it cool.
If you find that none of these solutions work and your orchid is still struggling in the heat, then you may need to consider getting rid of it. I know this sounds drastic, but sometimes it’s the best thing you can do for your plant. Orchids are very sensitive creatures, and sometimes they just don’t do well in certain climates.
Orchid Hardiness Zone
Orchid Hardiness Zone
Orchids are one of the most popular houseplants. They are known for their beautiful flowers and wide range of colors.
But did you know that orchids can also be grown outdoors? Yes, with the right care, you can grow these lovely plants in your garden!
When choosing an orchid for your garden, it is important to consider its hardiness zone.
Orchids are native to tropical and subtropical regions around the world. In the United States, they are typically found in zones 10 and 11. However, there are some varieties that can tolerate colder temperatures down to zone 5.
To find out what hardiness zone you live in, simply enter your zip code into this website: http://planthardiness.ars.usda.gov/. Once you know your zone, you can choose an orchid variety that will thrive in your climate.
Some of the most popular outdoor varieties include Phalaenopsis (moth orchids), Cattleya (lady slipper orchids), and Dendrobium (tree orchids).
These plants prefer full sun to partial shade and well-drained soil. With proper care, they will bloom prolifically year after year!
Cymbidium Orchid Temperature Tolerance
Orchids are one of the most popular flowers in the world, and Cymbidium orchids are some of the most popular of all. But what many people don’t realize is that these beautiful flowers are actually quite delicate, and their temperature tolerance is a big part of that.
Cymbidium orchids like it cool, with average daytime temperatures between 68 and 72 degrees Fahrenheit and nighttime temperatures between 60 and 65 degrees.
That said, they can tolerate a wider range of temperatures than many other types of orchids, which is one reason why they’re so popular. They can even handle short periods of time outside of this ideal range without too much stress.
However, it’s important to remember that Cymbidiums are still sensitive to changes in temperature, so sudden shifts should be avoided.
If you live in an area with extreme heat or cold, it’s best to keep your Cymbidiums indoors where you can better control the temperature. And if you do need to move them outdoors for any reason, make sure to do it gradually so they have time to adjust.
With proper care, your Cymbidiums will thrive and provide you with beautiful blooms for years to come!
Can Calla Lilies Survive in Zone 6?
Calla lilies’ hardiness in zone 6 is a topic of concern for gardeners. Zone 6 experiences cold winters, but with proper care, calla lilies can survive. These perennials thrive in well-drained soil and need protection during freezing temperatures. Mulching the soil and adding a layer of organic material can help insulate the bulbs and ensure their survival in Zone 6.
How to Protect Orchids from Cold Weather
Orchids are beautiful, delicate flowers that can brighten any room. But did you know that they’re also quite sensitive to cold weather? If you live in an area with cooler temperatures, you’ll need to take some extra care to protect your orchids from the cold.
Here are a few tips:
1. Bring them indoors. If the temperature outside is going to drop below 50 degrees Fahrenheit, it’s time to bring your orchids inside.
Place them in a sunny spot near a window where they’ll get plenty of indirect light.
2. Give them some humidity. Orchids like humid conditions, so try placing them on a tray of pebbles and water.
You can also mist them lightly with water every day.
3. Keep them away from drafts. Cold air coming from a vent or open window can damage your orchids’ fragile blooms, so make sure they’re not in direct line with any drafts.
4. Don’t let them get too dry (or too wet). Be careful not to let the potting mix your orchids are growing in get too dry or too wet – both extremes can be harmful to the plants. Water when the top inch of soil is dry, and always allow the potting mix to drain well after watering so that the roots don’t sit in soggy soil.
Conclusion
Orchids are a type of flower that is known for being delicate and finicky. However, there are some types of orchids that are actually quite hardy and can withstand cold temperatures. The trick is to choose the right type of orchid for your climate.
For example, if you live in an area with cold winters, then you will want to choose an orchid that is specifically labeled as being cold-hardy.
