Quercus pubescens 15-30cm

Quercus pubescens, commonly known as downy oak, is a species of oak tree native to Southern Europe. It is a deciduous tree that belongs to the Fagaceae family. Here's a description of Quercus pubescens and some information on its cultivation:

Description:

1. Leaves: The leaves of Quercus pubescens are generally elliptical, with a glossy dark green color on the upper side and a pale, hairy underside, which gives the tree its common name "downy oak." The leaves have deep, rounded lobes and are typically 4-8 cm long.

2. Bark: The bark of downy oak is typically gray-brown and develops deep fissures and ridges as the tree matures.

3. Acorns: Like many oak species, Quercus pubescens produces acorns. These acorns are oval and about 2-3 cm long, with a shallow cup that encloses the base of the nut. They usually take two years to mature.

4. Size: Downy oak trees can reach heights of 20-30 meters (65-100 feet) when fully mature.

Cultivation:

1. Climate: Quercus pubescens is well-suited for Mediterranean and temperate climates. It can tolerate both hot, dry summers and cold winters. It is adaptable to various soil types but prefers well-draining soil.

2. Sunlight: Downy oaks thrive in full sun or partial shade. They require at least 6 hours of direct sunlight each day to grow well.

3. Soil: These trees are not very picky about soil conditions but prefer soils that are well-drained. They can tolerate a range of soil types, including sandy, loamy, and clayey soils. Ensure proper drainage to prevent root rot.

4. Watering: Once established, downy oaks are relatively drought-tolerant. However, they benefit from regular watering, especially during their early years. Water deeply and consistently, especially during dry spells.

5. Pruning: Pruning is not usually necessary for downy oaks, but you can prune to shape the tree or remove dead or diseased branches during the dormant season in late winter or early spring.

6. Fertilization: Fertilize young trees in the spring with a balanced, slow-release fertilizer to promote healthy growth. Mature trees generally do not require regular fertilization.

7. Pests and Diseases: Downy oaks are susceptible to various pests and diseases, including oak gall wasps and oak powdery mildew. Regular inspection and appropriate pest and disease management measures may be necessary to protect your tree.

8. Mulching: Apply a layer of mulch around the base of the tree to help retain moisture, regulate soil temperature, and suppress weeds. Keep the mulch away from the tree trunk to prevent moisture-related problems.

Quercus pubescens is a valuable tree for its aesthetic appeal, providing shade, and supporting wildlife through its acorns. When cultivating this oak species, it's important to consider your local climate and soil conditions to ensure the tree thrives in your specific environment.
