- Prune and discard any diseased branches.
- Spray diseased areas with fungicide.

- Ensure your tree is not overwatered. Dig drainage ditches if the tree is in boggy ground.
How do you protect oak trees?
Water deeply, to one to two feet, in the outer two-thirds of the root zone. Alternatively, placing organic mulch under the tree can conserve moisture in the root zone by reducing surface evaporation. Mulch also inhibits the growth of weeds, which can compete with oak roots for moisture and nutrients.
What causes live oak trees to die?
Photo: Richard Sniezko, USDA Forest Service. Sudden Oak Death is caused by a fungal pathogen, actually a water mold, Phytophthora ramorum. It was transported into the Mid-Atlantic area on nursery stock from the West Coast, where the disease has caused widespread oak dieback in California and Oregon.

Can you save a tree from oak wilt?
Once an oak tree is infected with the oak wilt fungus, the tree will die and there is no treatment to save the tree. When an oak wilt infection is confirmed treatment can be applied to the surrounding trees to prevent the spread of this disease.
Can you overwater live oak trees?
In most circumstances it is not necessary to water mature established live oak trees. Shallow watering can in fact cause additional problems. Over watering or improper watering of oak trees may promote the growth of bacteria that can damage the root hairs and the ability of the tree to absorb water from the soil.
How far should you plant an oak tree from your house?
This question all comes down to tree size. After all, the wide-root oak tree that’s 70 feet tall needs much more room than the modest Japanese maple. A good rule of thumb is to start at about 8 to 10 feet away from your home for small trees and scale up to account for the tree’s mature height and spread.
What is the fastest growing oak tree?

Mature oaks usually reach about 80 feet in height with a branch spread of 170 feet in diameter, or 85 feet from trunk to branch tip in all directions. Once mature, live oak can live for several centuries, often up to 250 years, with a maximum lifespan of 500 years.
Will live oaks survive a hard freeze?
Many, if not all, live oaks will show signs of frost damage after a hard freeze. Like other plants, the main symptom will be brown, dead, or wilted leaves. Live oaks may show browning in patches or over a whole tree. Luckily, we expect most live oaks to recover from the freeze!
Can I treat oak wilt myself?
We recommend a trunk injection of Propizol. Propiconazole is a systemic fungicide that will suppress Bretiziella fagacearum. Because Oak Wilt is spread through root grafts and insect carriers, We recommend the treatment of non-infected oaks in close proximity to the infected trees to slow the spread of the disease.
How do you fertilize a live oak tree?
Fertilizer. In natural conditions, live oaks may not require fertilization, but in a managed landscape live oaks benefit from an appropriate fertilizer containing nitrogen, phosphorous and potassium. “We use a 30:10:7 (ratio) slow release fertilizer that will last up to two years.
How do you care for a live oak tree?
Prune out multiple leaders to leave one trunk, and eliminate branches that form sharp angles with the trunk. Caring for live oaks properly means pruning the trees each year for the first three years. Never prune in early spring or the first month of summer to avoid attracting the insects that spread oak wilt disease.
