Quercus suber aka Cork Oak
Taxonomy
Quercus suber, commonly known as the cork oak, is a medium-sized, evergreen oak tree in the Quercus sect. Cerris section. It is native to southwest Europe and northwest Africa and is an ancient species with fossil remnants dating back to the Tertiary period. The cork oak is the primary source of cork for wine bottle stoppers and other uses, such as cork flooring and cricket ball cores. It endures drought and is regarded as a defense against desertification. Cork oak woodlands are home to a multitude of animal and plant species. However, these forests are at risk as cork is increasingly being displaced by other materials as a bottle cap. This puts animal species such as the Iberian lynx and imperial eagles at risk of extinction. Trees are commercially grown in several European and African countries, most notably in Portugal and Spain. Cork is usually not harvested until a tree reaches the age of at least 30-40 years. Trees can mature to 40-70 feet tall and have leathery, wavy-toothed, ovate, shiny dark green leaves. The thick, rough, deeply fissured, corky bark with reddish-brown furrows is a unique beauty, particularly on older trees. Cork oak is also a rare houseplant that is easy to grow and needs regular watering to thrive. It prefers long-lasting, direct light and well-draining soil. Repotting when it doubles in size should supply enough nutrients, and it should be less than 1 foot from a window.
Common names
Cork Oak, Sr, Cork Bark OakHow to care for Cork Oak
Difficulty
Even if you don't have a green thumb, you can successfully care for Cork Oak due to its easy-going nature.
Water
Cork Oak should be watered regularly, allowing the soil to dry out between waterings.
Soil
Cork 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 Cork 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.
Toxicity
No verified data on the toxicity of this plant exists within Ploi's records. Should you, someone in your family, or your pet ingest plant material with an unknown toxicity level, it is recommended to seek medical advice.
Fertilizer
The Cork Oak is known for its slow growth and doesn't require fertilizing beyond its potting soil. Replacing the soil in its pot once a year should offer it sufficient nutrition. It's essential to remember that plants get their energy from the sun, not from fertilizers.
Growth-pattern
Cork Oak grows vertically and new growth emerges from the top of the plant.
Region of origin
Cork Oak’s native range is S. Europe to N. Africa.
