Oak Tree Care and Diseases

Oak Tree Varieties, Disease Diagnosis, Treatment & More

A noble American tree, oak trees are found in many landscapes and communities, adorning us with their stature and shade. There are nearly 400 different species of oaks, both deciduous and evergreen. Some of the most common species found in the Northeast include the Red Oak, White Oak and Black Oak. Depending on the species, oak trees can have gray, scaly bark or black furrowed bark. Leaves are typically green and can be serrated or rounded, turning red in the fall. The yellowish-brown flower of the oak tree is produced in the spring and is called a catkin. Acorns are the fruit housing the seed which is enjoyed by squirrels and other wildlife.

How to Grow Oak Trees: Oaks are durable trees which prefer rich, well-drained soil and have a long life span if given the proper care and room to grow.

Size of an Oak Tree: Oak trees range from 60-70 feet with spread 40-50 feet

Oak Tree Care and Service

Watering, pruning and using oak tree fertilizer on a regular basis will help keep oak trees healthy and better able to tolerate stress, insect and disease conditions or other tree problems.

Newly planted oak trees benefit from ArborKelp®, SavATree’s exclusive seaweed biostimulant fertilizer which aids in tree establishment, promotes root growth and heightens stress tolerance.

Mature and established trees benefit from oak tree fertilizer feedings of organic-based macro and micronutrients for the nutrition necessary to sustain their health.

If you’d like to establish oak trees in your landscape, we have access to consulting arborists that can help you select, purchase and plant new oak trees. For a complimentary consultation with a certified arborist to discuss the oak tree varieties that would work best in your landscape contact the location nearest you.

Oak Tree Pruning

Lateral, wide spreading branches give oak trees their strength and broad crown. A young oak tree should be pruned to develop a strong central leader.  Mature and developing trees should be pruned to remove dead or broken branches. Tree pruning helps promote healthy growth and structural integrity.

Your SavATree certified arborist is equipped with the latest techniques and state-of-the-art equipment to keep your oak trees healthy, beautiful and safe. Contact us today for information on tree pruning or any of our other oak tree care services.
