Fall is quickly approaching and you need to prepare your trees for the winter ahead. Don't wait until you hear the crunching of leaves below your feet to start. Your trees need nutrients, hydration and a good growth environment to continue to strive through the colder months. Contact us today to find out exactly what you can do to give your trees what they need to come back taller and fuller in the spring. 

3 Things your trees need:

   1. Nutrients


   3.Good Growth Environment

Things to watch for:

Sudden Oak Death

Sudden oak death (SOD) is the common name for a fatal tree disease caused by Phytophthora ramorum, a species of oomycetes that are similar to fungi.  SOD is one of 59 species of Phytophthora, all of which cause disease in plants.  Many Phytophthora species attack roots in poorly drained or anaerobic soils.  The primary hosts are coast live oak, California black oak, Shreve oak, tan oak, and canyon live oak.  Many more cultivated species are likely susceptible to P. ramorum.  Symptoms in other species are often expressed as leaf blight. P. ramorum can cause foliar disease in Douglas-fir, coast redwood and California bay laurel.  Unlike many Phytoph


Iron or manganese chlorosis (interveinal chlorosis) describes a condition in which a tree’s foliage loses its healthy green color and fades to a pale green or yellow hue. This condition, if allowed to progress, will cause slow growth, leaf loss, and eventually tree death. Chlorosis is often caused by deficiencies of the micro-elements iron and manganese, and is particularly prevalent in oak. In alkaline soils, iron and manganese become insoluble and unavailable to the tree. Trees growing in poorly drained soils are also susceptible to iron chlorosis thora species that infect roots, P. ramorum is mainly a foliar pathogen.

Oak Wilt

Oak wilt is a disease caused by the fungus Ceratocystis fagacearum that is specific to oaks (Quercus spp.). The fungus is spread through root grafts between neighboring trees and by insects.  Red Oaks are particularly susceptible to oak wilt. The infection causes leaf discoloration, defoliation and death in a very short period of time (from two months to one year).  Fungal mats will form under the bark and force outwards, cracking the bark of the tree.  White oaks are more tolerant of oak wilt infection.  Fungal mats will not form and it will take much longer for the tree to succumb to the disease.  White oaks will show infected annual rings when viewed in cross section.

Root Rot

Phytophthora is a genus of oomycetes that are similar to fungi.  There are 59 species of Phytophthora , all of which cause disease in plants.  Phytophthora ramorum is the species responsible for Sudden Oak Death.  Phytophthora are natural and universally occurring soil organisms which attack roots in poorly drained or anaerobic soils.  As infected roots discolor and decay, the result is wilt, canopy dieback, cankers on the trunk, general decline and death.  Phytophthora species are host specific attacking many types of trees including ash, cherry, pine, spruce, hemlock, fir, pear and dogwood.
