Quercus suber – The cork oak, a centuries-old bonsai for your garden
A 24-year-old outdoor bonsai with a majestic presence and an ancient character. Quercus suber, known as the cork oak, is one of the most fascinating oaks of the Mediterranean basin: evergreen, slow-growing, and remarkably long-lived. What makes it unique is its bark: thick, rough, and soft to the touch - the famous cork, which naturally regenerates over time. A tree that tells the story of decades of life and that, in bonsai form, becomes a piece of living art.
Important notes: The shape and dimensions of the bonsai are approximate (including the pot). The color and shape of the pot may differ from the photographs. As living plants, their appearance changes with the seasons; the images are therefore purely illustrative and do not constitute a contractual obligation.

Interesting facts
The bark of Quercus suber is the cork we all know: lightweight, waterproof, thermally insulating, and completely renewable. Harvesting it does not harm the tree - the bark grows back every 9-12 years. Cork has been used for centuries to seal wine bottles, as well as in construction, the aerospace industry, and fashion. Having a cork oak in bonsai form means caring for a piece of nature that is exceptionally useful and sustainable.
Placement
Place it outdoors in full sunlight all year round. Quercus suber is a quintessential Mediterranean species: it loves warmth, direct sunlight, and fresh air. It tolerates brief frosts but must be protected from prolonged and severe cold.
Watering
Moderate and regular: the cork oak is naturally adapted to periods of drought. Allow the substrate to dry out between waterings. Reduce watering significantly in winter and avoid waterlogging completely.
Fertilization
From spring to autumn, use the Hiryo Gold organic-mineral fertilizer or the fast-acting Nutribonsai fertilizer. Stop fertilizing in winter during vegetative dormancy.
Repotting
Every 3-5 years, in spring before vegetative growth resumes. The oak has a robust root system that requires adequate space. After repotting, watering with Mistral Bonsai's Vitabonsai revitalizer is recommended to speed up the plant's recovery.
Substrate
Terrabonsai - a special bonsai substrate that meets water and nutritional needs while promoting root development and overall vigor. Alternatively: 60% Kiryuzuna + 40% Akadama, which provides excellent drainage.
Pruning
During the winter months, while the plant is dormant. Make clean cuts, always leaving buds on the branch to ensure regrowth in spring.
Pinching
During the growing season: when the shoot has developed 4-6 leaves, cut it back, leaving 1-2 leaves to encourage branching and maintain a compact shape.
Wiring
Can be carried out all year round, preferably in spring. Pay attention to the faster spring growth to avoid marks on the corky bark, which is particularly sensitive.
