What Range Of Temperatures Orchids Prefer?

Orchids have a wide range of tolerance to day and night temperatures, with minimum temperatures being the lowest they can handle on a winter night. Daytime winter temperatures are 10°-15°F warmer than nighttime temperatures, while maximum temperatures are the highest temperatures orchids can tolerate in the summer. To promote flowering, it is important to place plants outdoors when the nighttime low temperature is 40F/4.4C or higher.

There are three distinct categories for temperatures: cool, intermediate, and warm-growing orchids. Cool orchids tolerate temperatures between 60-85°F during the day and 55-65°F at night. To ensure orchid health, it is crucial to maintain a day-night temperature swing of 10-15°F. Warm-growing orchids prefer temperatures between 18-30°C or 65-85°F, with the most commonly recommended range being 55º to 90°F (12.7º to 32.2ºC).

Phalaenopsis orchids grow best when there is a 10- to 15-degree difference between daytime and nighttime temperatures. Warm growers need daytime temperatures approximately 70°-85°F (20°-30°C) and should not go below 65°F/18°C. They thrive only when night temperatures are kept between 14° and 16°C with a daytime rise of about 10°C. Most orchids will love temperatures between 20°C to 32°C, but hybrid orchids can tolerate slightly higher temperatures.

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.

Can orchids grow in hot climates?

Love Orchids, a Hampshire-based nursery, offers orchids for various occasions, including summer. To grow them, they recommend adding extra water, plant food, and a position away from direct sun. Orchids can flower for months and last for years, and there are various types to choose from. During the Covid pandemic, the nursery struggled to find customers, so they switched to selling online. They have since continued to create beautiful orchid gifts for various occasions. To stay updated on their orchid offerings, sign up for their newsletter, as they offer them to their Orchid Club at cost price to help them find homes.

Can orchids get too hot?

Orchids, particularly those in cooler, shadier environments, can suffer from heat stress during hot summer months due to intense midday sun and bright sunshine. These plants, particularly sensitive ones like phalaenopsis, pleurothallids, paphiopedilums, and miltonias, can burn quickly. To treat this, apply fertilizers sparingly and flush the growing medium with clean water between applications. Be cautious of pests, as insects and viruses are more likely to attack weakened plants. During hot days, orchids require frequent watering to prevent dehydration, as high temperatures can quickly dry out mounted, basketed, and potted plants.

Is 60 degrees too cold for orchids?

Phalaenopsis, commonly grown orchids, are the most tender and sensitive to cold temperatures. They are strongly induced to bloom by temperatures in the mid-50s (12-13C), with a few exposures below 60F (15C) producing desired spikes. Vandas, on the other hand, are stimulated to bloom with sharp drops of temperature into the 50s at night, especially when temperatures can be induced to climb into the 80s (27-32C) by day. They can tolerate brief excursions into the upper 40’s but are best kept above 50 degrees.

Oncidiums of the “mule ear” type with thick fleshy leaves have warmth requirements similar to vandas, but thinner leaves can take temperatures into the 40’s with ease. Many hybrids in this group have been bred to Miltoniopsis and Odontoglossum to increase their cold tolerance. However, wind can strip heat rapidly from their thin leaves, making their cold tolerance greater in still air.

Are orchids sensitive to temperature?

Growing orchids indoors is a challenge, as they can be exposed to cool temperatures. Some warm-growing dendrobiums may drop their leaves if temperatures drop below 65° F/15. 5° C. To protect your orchids from cold, dry them off in the morning, water them in the morning, and wait until spring to fertilize if they go dormant. Temporarily enclosing them with plastic sheets, bedsheets, or freeze cloth can create a warmer microclimate. Move the orchids to a warmer location, and use incandescent Christmas lights and seed mats to slightly raise the temperature.

Greenhouses are an ideal method for regulating temperatures, with heaters, coolers, waterproof thermostats, shade clothes, ventilators, and partitions between warmer and cooler areas. These measures help ensure your orchids receive the ideal temperatures for optimal growth and health.

Do orchids like heaters?

It is imperative to ensure that orchids are not subjected to dry heat, as this can have a detrimental impact on their wellbeing. Therefore, it is crucial to refrain from positioning them in close proximity to vents or space heaters. A general guideline is that the temperature should be maintained at a level that is comfortable for the human occupant of the space, and that this temperature should also be suitable for the orchid.

Is it OK 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.

Is heat good for orchids?

Orchids, particularly those in cooler, shadier environments, can suffer from heat stress during hot summer months due to intense midday sun and bright sunshine. These plants, particularly sensitive ones like phalaenopsis, pleurothallids, paphiopedilums, and miltonias, can burn quickly. To treat this, apply fertilizers sparingly and flush the growing medium with clean water between applications. Be cautious of pests, as insects and viruses are more likely to attack weakened plants. During hot days, orchids require frequent watering to prevent dehydration, as high temperatures can quickly dry out mounted, basketed, and potted plants.

What conditions do orchids like?

Houseplant orchids prefer bright light but not direct sun, and prefer regular watering and misting with rainwater or boiled water. They need bark-based compost and prefer a medium in between. Tropical orchids don’t thrive in dry air, so mist leaves regularly. Tap water can be harmful, so use boiled or rainwater if possible. Avoid leaving them standing in water, as it can rot the roots. Phalaenopsis, the most widely grown houseplant orchid, is ideal for centrally heated homes and produces exotic displays of large blooms. They require minimal maintenance and are ideal for beginners.

What is considered high temperature 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 do orchids prefer?

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.
