In the wild, orchids feel right at home in the steamy, warm environment of tropical rainforests. To get those stunning blooms we all love, we need to recreate that cozy climate right in our own living rooms. Getting the temperature just right is the secret sauce for helping these exotic beauties truly thrive.
Finding the Sweet Spot
Orchids are definitely warmth-lovers. Whether you’re growing them as houseplants or keeping them outdoors during the summer, they need consistent warmth. Most species are happiest when it’s around 77°F (25°C). During the winter, they don’t mind a little “cool down,” but make sure the thermometer doesn’t dip below 60°F (16°C).
Different Strokes for Different Orchids
Not every orchid has the same “comfort zone.” While the popular Phalaenopsis (Moth Orchid) loves that 77°F average, other varieties like Ascocentrum, Cattleya, Miltonia, Odontoglossum, and Oncidium share similar tastes. If you’re growing Cymbidium, Dendrobium, or Vanda, these guys are real sun-seekers and can easily handle temperatures up to 86°F (30°C) in the summer.
Keep It Steady
Orchids aren’t big fans of surprises. You’ll want to avoid major temperature swings of more than about 5 degrees. A pro tip? Grab a “minimum-maximum” thermometer for your plant shelf. It’s the easiest way to keep an eye on the highs and lows so you can catch any drafty spots or overheating issues early on.
The Perfect Combo: Light and Heat
Temperature is a big piece of the puzzle, but it’s not the only thing. To get those show-stopping flowers, your orchid’s location needs a few more perks:
- Plenty of bright, indirect sunlight (avoid that harsh, scorching midday sun!)
- High humidity—aim for at least 60%, though they’ll love you even more if it’s higher.
When you combine the right warmth with the right light and humidity, your orchid will reward you with incredible growth.
Using a “Cool Down” to Boost Blooms
While we usually want to keep things steady, a little strategic temperature change can actually jumpstart new flowers. If your Phalaenopsis is being a bit stubborn about reblooming, try this trick:
About four weeks after the last blooming cycle ends, move your orchid to a cooler spot—somewhere around 60°F (15-16°C). Let it chill there for about six weeks, then move it back to its favorite warm sunny spot. Usually, it won’t be long before you see new buds starting to peek out!
