Oak trees are particularly prone to a disease known as California oak root rot. This is caused by the fungus Amalaria. This fungus is always present in the soil but does little or no damage to healthy growing trees and plants with good culture, which are desirable moisture, fertility, light and temperature. The difficulty here is that what is good culture for a lawn is not good culture for oaks. Your lawn likes to be heavily watered and fertilized all summer. The fertilizer does not damage the oaks, but the water can be deadly. This is particularly true of water that falls on the trunk and exposed roots.

Many people have modified their irrigation system to avoid any water falling within ten feet of the base of the tree and then covered these areas with a layer of decomposed granite or mulch. Installing rocks around the base of the tree is not recommended due to moisture and heat being trapped and possibly encouraging the fungus to become more active. You can also reduce the watering of your lawn within the drip line of the tree (the furthermost extension of the limbs) to the minimum required to keep the turf alive and growing. However, if you want your Coast Live Oak to outlive you, your children, and probably their children, you should remove all the irrigation within the drip line and declare this a dry zone. To maintain this area, simply allow it to become covered with a layer of oak leaves and remove any volunteer plants that may come in. The oak leaves will build a layer of natural forest soil or duff that will have a culture beneficial to the trees.

San Marino offers Oak Tree Preservation Program
The City of San Marino is widely recognized for its many beautiful, mature oak trees. But these trees, known for their mighty strength, are at risk. Excessive watering and improper ground cover, including turf and rocks, often adversely affect oak trees. These practices can lead to root decay, trunk failure, overall decline in tree health and the eventual death of the tree. The California Live Oak is especially susceptible to these conditions and is the main focus of the City of San Marino’s Oak Tree Preservation Program.
