Care tips
It requires full sun for optimal growth and tolerates drought well once established, though it appreciates occasional watering in very dry summers. It prefers well-drained, slightly acidic to neutral soils, and does not tolerate waterlogging. A common mistake is attempting to prune the bark prematurely or incorrectly, which can damage the tree and its cork production capacity.
