Evergreen oak
Quercus rotundifolia, commonly known as Evergreen Oak, Balearic Oak, or Corsican Oak, is a captivating evergreen tree that hails from the Mediterranean region, particularly the Balearic Islands and Corsica. This oak species is characterized by its rounded canopy, glossy green leaves, and charming yellow-green catkin flowers that grace its branches in the spring.
Plant Care:
Sunlight: Balearic Oak thrives in locations that receive full sun to partial shade. Ensure it has access to sunlight for healthy growth and development.
Soil: This oak species prefers well-draining, sandy, or loamy soil. A soil pH ranging from 6.0 to 7.5 is ideal. To create an optimal planting environment, mix the native soil with compost to improve its drainage and nutrient content.
Watering: Once established, Balearic Oak is relatively drought-tolerant. Water deeply and thoroughly during the initial stages of planting to encourage root establishment. Afterward, allow the soil to dry out slightly between waterings to prevent overwatering, which can lead to root rot.
Fertilization: Provide a balanced, slow-release fertilizer in early spring to support healthy growth. Avoid excessive fertilization, as it can lead to overly lush growth at the expense of the plant’s natural form.
Pruning: Prune sparingly to shape the tree and remove any dead or diseased branches. It’s best to prune during the dormant season, typically in late winter or early spring.
Pest and Disease: Balearic Oak is generally resistant to many pests and diseases. Regularly inspect the tree for any signs of infestation or disease, and promptly address any issues that arise.
Mulching: Apply a layer of organic mulch around the base of the tree to conserve soil moisture, suppress weed growth, and provide some insulation to the root system.
Landscape Use: Balearic Oak makes for an excellent shade tree and ornamental specimen in Mediterranean-style gardens and landscapes. Its evergreen foliage and unique growth habit add visual interest year-round.
