Quercus garryana aka Garry Oak
Taxonomy
Quercus garryana, also known as the Oregon white oak, Oregon oak, or Garry oak, is a member of the Fagaceae family and is found in the Pacific Northwest region of North America. Its range stretches from southern California to southwestern British Columbia, growing at altitudes ranging from sea level to 5,900 feet. There are three recognized varieties of this tree, named after Nicholas Garry, deputy governor of the Hudson's Bay Company. In the northern part of its range, Quercus garryana can reach up to 90 feet in height, while in the southern part, it is more commonly a shrub that grows up to 20 feet tall. The tree has large, lobed leaves that it sheds in the winter and is important for wildlife. Additionally, Brewer Oak is a rare houseplant that requires regular watering and well-draining soil. It thrives in direct light and should be placed less than a foot away from a window. Repotting the plant each time it doubles in size eliminates the need for fertilizers.
Common names
Garry Oak, Oregon Oak, Oregon White OakHow to care for Garry Oak
Difficulty
Even if you don't have a green thumb, you can successfully care for Garry Oak due to its easy-going nature.
Water
Garry Oak should be watered regularly, allowing the soil to dry out between waterings.
Soil
Garry Oak loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.
Lighting
To ensure optimal growth, the Garry Oak prefers bright diffused light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.
Dormancy
During the wintertime, it's common for Garry Oak to go dormant and their growth may slow down, so waterings should be spaced out more.
Toxicity
Ploi does not possess verified information regarding the toxicity of this particular plant. In the event that you, a member of your family, or a pet ingests plant material with an unclear toxicity level, it is highly recommended to seek the advice of a medical professional.
Fertilizer
The growth of Garry Oak is gradual and it doesn't necessitate any additional fertilizers. Replacing the soil in its pot once a year should suffice to provide the plant with sufficient nutrition. It's important to keep in mind that plants derive their energy from the sun's rays, not fertilizers.
Region of origin
Garry Oak’s native range is Western N. America - British Columbia to California.
