How Chilly Can Orchids Get?

Orchids are sensitive to cold temperatures, with minimum temperatures indicating the lowest they can handle on a winter night. Daytime winter temperatures are generally 10°-15°F warmer than nighttime temperatures, while maximum temperatures range from 50° to 80°F (10° to 27°C). Dendrocoryne dendrobiums and cymbidiums are the most cold-tolerant orchids that can grow in summer heat, accepting temperatures down into the 30°’s. Warm growers should have winter lows between 65°-70°F/ 18.3°-24.9°C.

Orchids prefer temperatures between 50° and 80°F (10° to 27°C), but occasional brief periods of temperatures above 100°F or drops even into the 30°’s (0 C) will not harm most orchids as long as no frost forms on the leaves. Cold injury includes damage from temperatures above and below freezing. For most orchids, low 50°s-60°F/ 10°-15°C is enough of a chill to initiate reblooming. Cymbidiums are very cold-tolerant, with an ideal minimum temperature of 40°F, although they tolerate temperatures into the mid-30’s and will survive light freezes.

Phalaenopsis prefer temperatures below 60 degrees, while cattlyea orchids can survive temperatures below 55°F. Dendrobiums are okay until it goes, and daytime temperatures of 75°F or more and nighttime temperatures of 65°F or more are ideal. In the fall, start bringing all plants indoors or in greenhouses when the nighttime low reaches 55°F/12.7C for the first time. It is better to be more cautious when buying orchids during the colder months, as they are more susceptible to damage.

In summary, orchids require varying temperatures and protection to thrive during winter months. To ensure their survival and growth, it is essential to maintain a consistent temperature range and avoid extreme cold conditions.

How do you save an orchid that got too cold?

In the event that your orchids have sustained damage as a result of exposure to low temperatures, it would be erroneous to assume that they have perished. It is recommended that the medium be allowed to dry and that the plants be maintained in a humid environment away from direct sunlight and high temperatures. It is recommended that the plant be watered only until new growth emerges, after which plain water and a light fertilizer should be used. In some cases, winter chills may facilitate bud initiation and flowering, so it is erroneous to assume that the plants are dead.

How to keep an orchid alive in winter?

Orchids thrive in humid environments, and creating a “humidity tray” can increase the humidity level around your plant. Fill a shallow bowl or saucer with pebbles or stones, place your orchid on top, and fill the tray with water. This low-cost and easy option helps replicate the natural tropical environment of your plant.

Ensure your orchid receives enough light, as winter means shorter daylight hours. Place them in the sunniest room with the most windows, but avoid placing them on window sills that would put too much direct light. Choose an east-facing window for optimal lighting.

Regularly check your orchid’s roots for plumpness and greenness, and check for brown or black roots, soft, slimy roots, dry, or grey roots. Wrinkled leaves indicate a need for extra water.

In summary, orchids thrive in humid environments, and proper care and care can help maintain their health. Regular checks and maintenance can help ensure optimal growth and longevity.

Is it OK to sleep with orchids?

Orchids, such as the Moth Orchid, are non-parasitic plants that absorb water and nutrients from rain and air, making them ideal for the bedroom. They release oxygen through the night, making them a great gift. Houseplants have been proven to reduce street anxiety, improve air quality, and help improve sleep. Photosynthesis, the process by which plants absorb and emit carbon dioxide, is a key factor in promoting better sleep. Plants capture around 25 percent of all carbon dioxide emitted from fossil fuels, making them a valuable addition to any home.

What temperature do orchids like at night?

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.

How cold is too cold for an orchid?

The occurrence of cold damage in orchids is contingent upon the temperature dropping below 30° F (0° C), which causes the water on the leaves to freeze. The symptoms of cold damage to orchids include the formation of pseudobulbs with a soft, brown appearance, the blackening of leaves, the development of brown or black pits on the leaves, and the growth of leaves that are brown and limp. The aforementioned symptoms manifest on the subsequent day following exposure and become more apparent as the orchid warms. It is imperative to maintain an optimal temperature range for orchids.

When should you bring orchids inside?

To ensure orchids can initiate flower spikes, it is recommended to bring them indoors when outdoor temperatures drop below 50°F/10°C. Phalaenopsis and Cymbidiums, two types of orchids, require temperatures below 50°F for flower spikes. Providing proper winter temperatures will enable them to bloom later on. To learn the amount of cold an orchid can take and how much cold they need to rebloom, follow the guide provided.

What room temperature do orchids like?

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.

Can you leave orchids outside in the winter?

Orchids can be placed outside based on their cold hardiness, with Cymbidium being the most cold-hardy. The nighttime low temperature is the most crucial indicator for outdoor placement. Cymbidiums can be placed outside when the lows are 40F/4. 4C or higher consistently. For other orchids, wait until the lows are 55F/12. 7C or higher. In the fall, start indoors or in greenhouses when the nighttime low reaches 55F/12. 7C for the first time.

Be cautious in the fall as frost damage can be irreversible and potentially kill the plant. Outdoor exposure can bring new life to orchids, as some may bloom or grow larger or recover faster from ailments.

What does cold damage on orchids look like?

Cold damage on orchids can cause whitening of foliage and stems, which turns brown as the effected tissue dies. This damage can be limited to unsightly patches or can be infected with bacterial rot, spreading the plant and causing further damage. Softening of edges or oozing of brown fluid indicates bacterial infection. Removal of the leaf or stem is a drastic solution, but cupric hydroxide (Kocide or Champion) and mancozeb (Manzate or Dithane M45) can be effective treatments. A slurry can be created by adding water to the chemicals in a jam, which can be brushed on the lesions.

Can orchids recover from cold damage?

In the event that your orchids have sustained damage as a result of exposure to low temperatures, it would be erroneous to assume that they have perished. It is recommended that the medium be allowed to dry and that the plants be maintained in a humid environment away from direct sunlight and high temperatures. It is recommended that the plant be watered only until new growth emerges, after which plain water and a light fertilizer should be used. In some cases, winter chills may facilitate bud initiation and flowering, so it is erroneous to assume that the plants are dead.

What orchids like the cold?

Dendrobium species, including Dendrobium cymbidium, are the most cold-tolerant orchids, capable of growing in summer heat and withstanding temperatures as low as the 30s.
