Description

Over the past several years, Sudden Oak Death (SOD), caused by a highly contagious fungus called Phytophthora ramorum, has killed tens of thousands of oaks (Quercus) and tanoaks (Lithocarpus densiflorus) along the fog belt of the northern coast of California and some of the inland counties as well - some ten counties altogether.

There is a list of almost thirty different species besides oaks which are now showing signs of being infected with this fungus.

Symptoms

The pathogen appears to kill the bark around the trees, cutting off its flow of nutrients. Symptoms include bleeding cankers on trunks, leaf spots and browning, and twig dieback. Bark beetles may be associated with later stages of tree decline.

Arborwell Tree Service's Wellness Approach

Arborwell has a specially designed Oak Tree Wellness Program. This program treats all species of Oak including; Valley, Live, Blue, Black, Red, and Pin Oak.

The program includes quarterly visits with seasonal applications:
Winter - Horticultural oil application to control over wintering chewing and sucking insects.
Spring - Tussock Catipillars & Oak Moth control & Powdery Mildew
Summer - Sudden Oak Death (SOD) control applications to combat the disease of Phytophthora ramorum.
Fall - Application of Oak fertilization and Mycorrhizae

Recomendations to improve cultural conditions such as irrigation, mulch and excessive soil around tree trunks will be made as necessary.
