Here are a few orchid species that are known to thrive in Colorado:

  1. Cymbidium Orchids: These orchids are known for their ability to tolerate cooler temperatures, making them a great choice for Colorado’s climate.

It is important to research and choose orchid species that are well-suited for Colorado’s climate to increase your chances of success.

Providing the Right Growing Conditions

Creating the right growing conditions for your orchids is essential for their overall health and well-being. Here are some key factors to consider:


Orchids require the right amount of light to thrive. In Colorado, where the sun can be intense, it is important to provide your orchids with filtered or indirect light.

Placing them near a north or east-facing window is ideal. If you notice that your orchids are not getting enough light, you can supplement with artificial grow lights.


Colorado’s temperature can vary greatly throughout the year. Orchids generally prefer temperatures between 60°F and 80°F during the day and slightly cooler temperatures at night.

It is important to protect your orchids from extreme temperature fluctuations, especially during the winter months.

Consider using a humidifier or placing your orchids on trays filled with water to increase humidity levels and maintain stable temperatures.


As mentioned earlier, orchids thrive in humid environments. However, Colorado’s dry climate can make it challenging to maintain adequate humidity levels.

To increase humidity around your orchids, you can use a humidifier, place a tray filled with water near your orchids, or mist them regularly.

Grouping your orchids together can also help create a microclimate with higher humidity levels.


Proper watering is crucial for orchid care in Colorado. Orchids should be watered thoroughly but allowed to dry out between waterings. Avoid overwatering, as this can lead to root rot.

It is recommended to water your orchids in the morning to allow any excess water to evaporate throughout the day.

Potting Mix

Choosing the right potting mix is important for orchid care. Orchids require a well-draining mix that allows air to circulate around the roots.

A popular choice for orchids is a mix of bark, sphagnum moss, and perlite. Avoid using regular potting soil, as it retains too much moisture and can lead to root rot.

Common Orchid Pests and Diseases

Like any other plant, orchids are susceptible to pests and diseases. Here are a few common pests and diseases that you may encounter when growing orchids in Colorado:

  1. Aphids: These small insects feed on the sap of orchid plants and can cause damage if left untreated. Use insecticidal soap or neem oil to control aphids.
  2. Spider Mites: Spider mites are tiny pests that can cause webbing and damage to orchid leaves. Regularly misting your orchids and keeping humidity levels up can help prevent spider mite infestations.
  3. Root Rot: Overwatering or using a potting mix that retains too much moisture can lead to root rot. Ensure that your orchids are potted in a well-draining mix and avoid overwatering.


Growing orchids in Colorado’s unique climate can be challenging, but with the right knowledge and care, it is possible to create a thriving orchid garden.

By selecting the right orchid species, providing the right growing conditions, and being mindful of common pests and diseases, you can enjoy the beauty of orchids in your Colorado garden.
