Oak Tree Maintenance: Diseases and Care

Posted on April 7th, 2016 by Prunin Arboriculture & Landscape

Oak trees are majestic hardwoods that provide your home with an abundance of shade as well as make your property visually appealing. There are around 400 different species of oak trees, including both evergreen and deciduous. Some of the common species include White Oak, Red Oak, Live Oak and Black Oak. As they are low-maintenance plants, regular maintenance will keep them healthy for a lifetime.

Maintaining General Health
Oak trees prefer full sun and well-drained soil. They enjoy a natural change of seasons, with regular irrigation while the tree is establishing its root system. However, when the roots are established water them only once a month. As well as select only drought-tolerant plants that don’t require summer watering, when planting around oak trees. You can also lay 2 to 3 inches of mulch around the base to keep the soil from drying out and preventing growing weeds that might steal nutrients from the tree.

Proper Oak Tree Care
For the trees to remain healthy, they need proper tree care and regular maintenance.

Fertilizing
Newly planted oak trees, as well as those that are already established, will benefit from being fertilized. Oak trees are extremely durable, but fertilizing on a regular basis helps them to establish and maintain a strong root base.

Watering
Watering is also a necessity, as oak trees are very large and need an abundance of water. While their roots go deep into the soil to extract water, occasionally supplementing the amount of water they receive will ensure the tree gets what it needs to thrive.

Pruning
Oak trees also need to be pruned to remove branches and twigs that are not growing sufficiently or are hampering the growth of other areas. Pruning helps oak trees to develop the strong, sturdy branches that give the tree its stature. Pruning not only strengthens the tree it gives the tree the room it needs to flourish. But don’t prune them from March through July, as this is when small beetles can transmit oak wilt, a fungal disease.

Landscaping
Select drought-tolerant plants while planting around oak trees. Plant them at least 6 feet away from the base of the oak trees. Lay 2-3 inches of mulch around the base of oak trees to prevent weeds and soil from drying.
