Arborist Advice

Hypoxylon Canker Fungus
  Hypoxylon Canker

  Hypoxylon Canker is a disease that causes cankers and death of oaks and other hardwoods. It usually does not affect healthy maintained trees, but will readily infect the sapwood of a tree that has already been damaged or stressed. Due to the droughts of the past few summers, many trees have been affected in Southeast Texas. The first sign of this fungus is a thinning crown and/or dieback  of one or more branches. Near or after death, the tree starts sloughing off it's outer bark. This exposes large numbers of spores which become airborne and spread to the surrounding trees. Entry usually occurs through injured surfaces on the limbs and trunk. Chemical treatments are not effective because the fungus is located within the tree. Once a tree is actively affected with Hypoxylon, it will most likely die. The best solution is the removal of the affected tree by a professional. Control is achieved by maintaining your trees in a healthy condition.
   

Unsightly Topped Tree

Do Not Top Your Trees!!!


  Tree topping, also known as crowning is the practice of removing the canopy and large limbs of a tree. This leaves stubs and other lateral branches that are too small to assume the role of a terminal leader. Topping is perhaps the most harmful tree pruning practice known. Trees require a large leaf surface area to provide food for maintenance and growth. Topping cuts off a major portion of the tree's foodmaking potential and depletes the tree's stored reserves. This results in the growth of unsightly water-sprouts (epicormic shoots), which grow into weak and unsafe limbs. Along with a topped tree's ugly appearance, a topped tree will require constant maintenance and has an increased potential to become hazardous. Certified arborists and other legitimate tree professionals do not practice tree topping. If problems caused by a tree can not be solved by responsible pruning practices, it should be removed and replaced by a more suitable specimen. In many cities topping is banned because of the public safety factor and the potential for lawsuits.

Harmful Tree Insect

Harmful Insects


  A wide variety of insects cause harm to the trees in our area. Some of these include scale, southern pine beetles and spider mites. These insects can feed on the trees, depleting their nutrients sometimes resulting in death. Before you decide to take drastic measures, remember that not all insects on trees are damaging. Some are beneficial in pollination or could be predators to tree damaging insects. Our arborists are trained to identify these insects and provide an effective treatment plan that still conserves the beneficial organisms in your area.
