Orchids are classified into three categories: warm-growing, cool-growing, and tropical. Warm-growing orchids thrive in temperatures between 50° and 80°F (10° to 27°C), while cool-growing orchids thrive in temperatures between 15-21C (60-70F) and 10-12C (50-55F). Orchids generally prefer warm temperatures and humidity, and their optimal daytime temperatures are between 50° and 80°F (10° to 27°C).
To keep orchids warm during winter, proper watering, fertilization, sunlight exposure, and temperature control are essential. Warm-growing orchids typically thrive between 55° to 90°F (12.7° to 32.2°C), while cool-growing orchids thrive between 15-21C (60-70F) and 10-12C (50-55F). Most orchids thrive at room temperatures between 20°C and 28°C, but it is important to ensure the temperature does not fluctuate too much and avoid sudden temperature swings.
Orchids originate from warm tropical Asia, making homes ideal environments for them, as they thrive in temperatures between 17–26 degrees. Temperature triggers blooming in orchids, and they need a 10°-15° temperature drop at night.
In summary, orchids are classified into three categories, with normal room temperature being safe for growing. However, if you have a “pre-war” home, you may experience temperature swings. Proper watering, fertilization, sunlight exposure, and temperature control are crucial for maintaining the health and happiness of your orchids during winter.
📹 Temperatures for Indoor Orchids: Does Temperature Influence Blooms?
Finding the correct temperature for growing your orchid is essential for it to bloom. You can water, apply humidity, provide light, …
What temperature is too hot for orchids?
Orchids are classified as cool-, intermediate-, or warm-growing depending on their temperature needs. These ranges are typically defined as warm 80-90F days and 65-70F nights, intermediate 70-80F days and 55-65F nights, and cool 60-70F days and 50-55F nights. These ranges are for winter conditions, as cattleyas and many oncidiums can tolerate summer days into the 90s. However, temperatures above the low 90’s cause physiological stress on plants, which is tied to a significant drop in night temperature and the short duration of summer heat.
These ranges are safe estimates, as the ability to survive temperature extremes is closely tied to environmental and cultural practices and the duration. For example, a few hours of temperatures in the 40’s will have a remarkably different effect on phalaenopsis than a whole growing season of too-cool conditions.
Plants grown under uniformly warm conditions will be more stressed by sudden cold snaps than those grown under gradually acclimated conditions. Wet plants can be more easily damaged by cold than dry plants. Some clones are more tolerant of extreme conditions, which is the basis for the development of warmth-tolerant or cold-tolerant landscaping plants.
Where is the best place to put a orchid?
Orchids thrive in east or south-facing windows, as they provide enough light for growth. Avoid west and north-facing windows, as they can be too hot and dark. Use a sheer curtain to cast light shade. Avoid direct light, as it can cause sunburn. Reposition plants as seasons change and avoid leaves touching the glass. Leaf color indicates the amount of light, with a grassy green color indicating sufficient light for bloom. Orchid DealWire offers exclusive savings and promotions for orchid vendors. Remember to avoid touching the windowpane in cold climates.
Do orchids like hot sun?
Orchids prefer bright light but not direct sunlight, especially in hot, dry weather. They prefer cooler temperatures and prefer east or west-facing windows and bathrooms. A humid climate with indirect light is ideal. Avoid placing your orchid near a fruit bowl as it may lose all its flowers overnight. If your orchid roots are dry and shrivelled, remove them from the bark, but leave them if they are green and healthy. Rotten roots are usually due to overwatering.
Is it okay to put orchids outside in the summer?
Orchids thrive in humid jungles, attaching their roots to tree branches for support and soaking in filtered light. To keep them healthy and blooming in your backyard garden, mimic their natural habitat by providing regular misting and watering. Outdoor orchids need more natural protection, such as tree branches with filtered light, or planting them in pots under a tree canopy. Attaching orchid roots with cotton string or planting them in pots can help them decompose naturally over time.
Monitoring outdoor temperatures is crucial for orchids’ health. They prefer temperatures between 50 and 90 degrees F by day, making summer in a Mediterranean climate optimal. At night, they need a temperature drop of 10 to 15 degrees F, which they usually receive naturally outdoors. Orchids can tolerate warmer temperatures as long as they receive plenty of air flow, so provide space for them to enjoy the breeze.
What climate is best for orchids?
Orchids thrive in temperatures of 75°F or higher during daytime and 65°F or higher at night. However, winter temperatures may not be ideal, so it’s crucial to prevent them from being exposed to temperatures significantly colder. If you experience damage, investigate if cold damage may have been the cause and determine when it occurred. If you suspect cold damage, take steps to prevent it from happening in the future.
What happens if an orchid gets too hot?
Phalaenopsis orchid leaves are robust and healthy; however, when exposed to high temperatures, they begin to wither and develop a wrinkled appearance. It is imperative to closely observe these leaves during periods of elevated temperatures to identify any potential health concerns.
Should orchids be in a warm room?
Orchids prefer cool, bright rooms and bathrooms, but should not be placed near fruit bowls or fruit ripening. They are sensitive to ethylene gas produced by ripening fruit, especially bananas. Orchids need water once a week, but in high temperatures, it should be twice. To absorb water, dunk the plant in water for a few minutes or run it under tap water for 20 seconds. Orchids are adaptable and can adapt to any water source, making them a versatile and beneficial plant.
How hot is too hot for orchids?
Warm growing orchids typically grow between 55º to 90ºF (12. 7º to 32. 2ºC), but most species can tolerate five degrees Fahrenheit greater in each direction. Plants can tolerate extremes outside of this range for short periods due to air movement and humidity. However, culture variables can affect the actual temperatures a plant can withstand without stress. Orchids are adaptable and can grow outside these ranges, but optimum growth is achieved when grown warm. Orchid DealWire offers exclusive savings and special promotions for orchid vendors.
What temperature hurts orchids?
Orchids typically thrive in temperatures between 50° and 80° F (10° to 27° C), but occasional periods above 100° F or even in the 30s (0 C) can be harmless as long as no frost forms on the leaves. Cold injury, chill injury, and freeze injury are all types of damage caused by temperatures above and below freezing. Symptoms usually appear days after exposure to low temperatures, with the rate of development depending on the severity of the exposure and the conditions in the growing environment.
The post-exposure environment affects the degree of injury and symptom development, with the importance of post-stress handling varying with the severity of cold stress. Overall, proper post-stress handling can significantly influence the damage to plants exposed to extreme temperatures.
Do orchids like air conditioning?
To ensure the health of your orchid, it’s essential to keep it away from direct airflow from air conditioners and vents. Ensure the room temperature is between 65-80 degrees Fahrenheit during the day and 55-65 degrees Fahrenheit at night. Orchids thrive in temperatures between 55-65 degrees Fahrenheit at night, but in direct contact with a fan, temperatures could drop below this range. Therefore, it’s crucial to keep your orchid away from direct airflow and maintain a consistent temperature range.
Can orchids get too much sun?
Orchids can suffer from yellowing leaves, premature loss of foliage, sunburn, and shriveled pseudobulbs if they get too hot. To prevent these issues, ensure proper hydration and increase watering frequency. Orchids can survive winters, as they are adaptable and resilient plants. Bring them indoors before frost arrives. Care tips include avoiding extreme temperatures below 50°F, bringing them indoors, and maintaining their health and beauty.
📹 Orchids suited for warm climates
Orchids are such a diverse group of plants that it’s easy to find those species suited for our environment. So today we will talk …
Hi Danny, I am living in a tropical island, and I have just started to explore growing orchids as a hobby. I already have two phalenopsis and two vandas…the phals I bought with blooms and now they have stopped blooming, how do I water and fertilize them..they are growing in a potted media. The vandas are very young…please share some tips on caring for these young ones watering and fertilizing them.
Another article with great advice. Do you do the audio after editing the article? I admire the integration and continuity of your narration as the scenes change in the article. Maybe you should do a article on how your narrations flow so smoothly from one article transition to another. Your articles are very professionally done.
Thankyou Danni for a fabulous article. I really like Cattleyas, particularly the fragrant ones. I have purchased a Cattleya Chocolate Drop ‘Kodama’AM/AOS x Blc. Mount Sylvan and a Blc Greenwich which are both supposed to have great fragrances. They are due to arrive tomorrow!!! (:D Hooray) I would love to see a article with your suggestions for the most fragrant orchids. The internet is a bit confusing on this subject. I also purchased a Rhynchostylis gigantea and Rhync. retusa…. do you know anything about these – I can’t see anything in your articles (or anyone else I like listening to) about Rhynchostylis’s. Thanks again.
Those Dendrobium Nobiles are real champions, aren’t they? Mine sat in full sun for half the day all summer long in extreme temperatures and not even the slightest sign of burned leaves or any other damage. My poor Nelly Isler on the other hand didn’t make it through the summer which is strange because my Miltoniopsis made it through without any problems. Maybe I was unlucky with this particular individual. I’ll buy another one this winter but if this one too dies next summer, I’m not buying another one ever again.
Hi Danni, Very interesting article, I sometimes wish you lived next door lol Yes you guessed it I’m having problems, All my phals have gone floppy, And leathery looking, And my brand new vanda is going yellow, As is my new nelly isler i got a few days ago, Add to that my beautiful dendrobium nobile also looks a bit yellow, Strange that it all happened in the last few days, Not too bothered about the phals though They don’t do much except take up space. but the rest I pretty gutted about, 🙁
Last one, lol, sorry. What would disturb the growth of the orchids roots? My orchids are fussy with this, it has seemed that with my phals, for example, i have touched accidentally or tease the roots while potting and they get stunted. I thought that if you see growth tips in the roots there are good for a repot or am i getting it wrong?
I live in the southern US where it’s hot and humid but we do get a a slight winter. I have had the hardest times keeping my orchids alive and have never had one re-bloom. What am I doing wrong? I keep them in a bark mix, water only when dry and keep light indirect. I keep them inside, how do I produce humidity in the pots? Is this why some of yours are double potted? Please help!!! I hate seeing these plant babies of mine dwindle and it’s sad they don’t produce flowers again….
hi danny, pardon my ignorance, what is the difference between miltonias and miltoniopsis? i havent read a lot about them but from what i read their wasnt an obvious difference. Also, do you know if the phaleanopsis deliciosa is a species? It looks like it because of the spike that can rebloom, i think but im not sure if that trade is exclusive to species phals?
Complex Phalaenopsis hybrids do very well in warm to hot climates. They can be in bloom/developing flowers all year round. In tropical climate (very dry winter and humid summer), they can be kept attached to a tree with absolutely no care and still be constantly in bloom. It would be easier to list what orchids are not suited for warm climates (which would be highland and temperate orchids), since most of them are equatorial to subtropical plants.
