It can reach up to 25m in height and thrive in a diverse range of habitats. This durable oak is difficult to topple, making it a perfect choice for windy areas and parks. The English oak is a long-lived species, which can attract wildlife such as birds, squirrels, and bees. Its acorns are a valuable food source for many species, and its foliage provides protection from the elements. Along with its hardy nature and beauty, the English oak is a valuable asset to any landscape.

watering

English oak should be watered when the top 2-3 inches of soil feels dry. It is best to water the tree deeply, approximately once every 7-10 days. It is important to avoid over watering as this can lead to root rot or poor plant health. During the hot summer months, it may require more frequent waterings. Deep watering is especially important for newly planted oaks as they establish their roots. Supplemental water may be needed during times of extreme drought.

sunlight

English oak plants grow best with an abundance of sunlight. This plant should be exposed to full-sun for at least 5-6 hours per day, preferably in the morning or late afternoon, as the intense midday sun can be too hot for the plant. English oaks can tolerate partial shade, but this should be limited to the summer months when the sun is strongest. In winter, it’s best to keep the plant in full-sun to avoid potential winter weather harm, such as early bud burst or cold winter damage.

pruning

Pruning an English oak (Quercus robur f. fastigiata) should be done carefully and regularly. Every 2 to 3 years, the oak should be pruned to shape it and keep it healthy. Pruning involves removing dead limbs, crossing branches, and suckers, and thinning out the crown, if necessary. For more formal plantings or gardens, the desired shape should be achieved by the removal of excessive growth. It is important to prune English oak tree carefully so as not to damage the tree, and pruning should be done in late winter or early spring. Pruning during this time will help reduce the chances of diseases such as oak wilt, and oak wilt spreads more easily when pruning occurs during other parts of the year. Be sure to use clean, sharp tools, and never top the tree. Topping results in an unnatural shape and can weaken the tree.
