Quercus macrocarpa, commonly known as the bur oak, is a large deciduous tree native to North America. It is part of the Fagaceae family and the Quercus genus. The bur oak is known for its impressive size and longevity, often living for several centuries. It has a thick, corky bark and large acorns, which are a key food source for wildlife. The tree undergoes a dormancy period during the winter months.

DETAILS
Care Instructions
Bur oaks require full sun and thrive in moderate temperatures. They are relatively drought-tolerant once established but benefit from occasional deep watering during prolonged dry periods. The tree prefers moderate humidity levels and can tolerate a range of soil conditions, although it grows best in well-drained soils.Soil
Bur oaks prefer loamy soil with good drainage. They can tolerate a range of soil types, including clay and sandy soils, but they thrive in nutrient-rich, well-drained loam. The soil should be allowed to dry out between waterings to prevent root rot.Fertilizer
Bur oaks generally do not require fertilization if planted in nutrient-rich soil. If necessary, a balanced, slow-release fertilizer can be applied in early spring to support growth. Over-fertilization should be avoided to prevent damage to the tree.Repotting
As a large tree, bur oaks are not typically repotted. Instead, they should be planted in a permanent location with ample space for growth. Transplanting young saplings should be done in early spring or fall to minimize stress.Propagation
Bur oaks can be propagated from acorns. Collect acorns in the fall, remove the caps, and plant them in a well-draining soil mix. Keep the soil moist but not waterlogged. Germination typically occurs in the spring. Seedlings should be transplanted to their permanent location after one or two years.Pruning
Pruning is essential for maintaining the shape and health of bur oaks. Prune in late winter or early spring before new growth begins. Remove dead, diseased, or crossing branches to improve air circulation and reduce the risk of disease.Toxicity
Bur oaks are not toxic to pets or humans. However, the large acorns can pose a choking hazard to small animals and children if ingested.Additional
Bur oaks are highly valued for their strong wood, which is used in furniture and flooring. They also provide significant ecological benefits, offering habitat and food for various wildlife species. Regular monitoring for pests and diseases, such as oak wilt, is recommended to ensure the tree's health.REVOLUTIONIZE YOUR PLANT CARE
