Quercus glauca aka Ring Cup Oak

Ring Cup Oak’s native range is E. Asia - China, Japan, Himalayas.

Ring Cup Oak should be watered regularly, allowing the soil to dry out between waterings.

Ring Cup 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.

Ring Cup Oak requires abundant, bright, and direct light to thrive. The best placement for this plant is within one foot of a window to ensure it receives enough light. If you live in an area with more extreme weather, such as hot summers or cold winters, you may need to adjust the placement of the plant accordingly. During hot summer months, it is important to place the plant away from full sun, as this can cause the leaves to yellow or burn. During cold winter months, it is best to move the plant closer to the window to take advantage of the extra light that can help it survive. By keeping an eye on the current weather in your area, you can make sure your Ring Cupped Oak is always in the right place to thrive.

The Ring Cup Oak is characterized by its slow growth and doesn't need fertilization in addition to its potting soil. By renewing the soil in its pot once a year, it should have enough nutrition. Remember, plants get their energy from sunlight, not from any fertilizers.
