Injuries from lawn maintenance equipment not only physically damages the tree, but also creates an open wound attractive to diseases and borers, especially the dogwood borer which can girdle the tree, causing it to die back. Dogwoods have relatively shallow roots. Supply supplemental irrigation in the summer and fall if rainfall is short.
Leaves should not be allowed to wilt, resulting in stress. Although dogwoods are hardy here, they are susceptible to stress from varying sources. Drought, too much water flooding, poorly drained soils , too much fertilizer, and herbicides are some common stress factors. Stressed trees are susceptible to various types of borers and root rots which can lead to further problems. Dogwoods do not need much fertilizer, and are quite sensitive to herbicides, so care must be taken for dogwoods growing in maintained lawns.
Some folks may have heard of a disease which is killing many dogwoods on the east coast. The disease is called dogwood anthracnose, and causes leaves to burn on the edges, lower limb die back and eventual death of tree.
Fortunately, this disease does not seem to do well or occur in Texas or in nearby states. Dieback on our local trees is usually due to various stress factors occurring over a period of years, coupled with dogwood borer injury and other insects and diseases. Delivered by FeedBurner.

The disease, whose origin is unknown, kills trees within two to three years of initial infection. Trees in moist sites on lower slopes and bottomlands are most susceptible. Some scientists feel that the blight is so widespread that they hold little hope of saving flowering dogwood in the wild.
Habitat Flowering dogwood grows best in moist soils, but will grow in drier habitats. They like to grow in the shade of larger trees as understory plants. Distribution Flowering dogwoods can be found in eastern deciduous forests as far north as Maine, extending west to eastern Texas and Missouri. Other The common name, dogwood, comes from England. Years ago, people there used the bark of the bloodtwig dogwood Cornus sanguinea to bathe mangy dogs.
Every weekend showcases the historic homes of Palestine, as well as a Dogwood Excursion aboard the Texas State Railroad, a unique way to view the scenic piney woods. An old and beautiful legend has it that, at the time of the crucifixion, the dogwood was comparable in size to the oak tree and other monarchs of the forest. Because of its firmness and strength it was selected as the timber for the cross, but to be put to such a cruel use greatly distressed the tree.
Sensing this, the crucified Jesus in his gentle pity for the sorrow and suffering of all said: "Because of your sorrow and pity for My sufferings, never again will the dogwood tree grow large enough to be used as a gibbet. Henceforth it will be slender, bent and twisted and its blossoms will be in the form of a cross -- two long and two short petals. In the center of the outer edge of each petal there will be nail prints -- brown with rust and stained with red -- and in the center of the flower will be a crown of thorns, and all who see this will remember.
