Arborist ServicesOn staff we have Certified Arborists (certified by the International Society of Arboriculture), member of American Society of  Consulting Arborists, Texas Oak Wilt Qualified Arborist, and Tree Risk Assessment Qualified Arborists.   

Insect, Disease, and Injury Diagnosis

A thorough tree diagnosis by a certified arborist from Dallas Tree Surgeons can best determine a plan to bolster growth, help prevent disease, or strengthen a tree’s defense system against injury. Diagnosis of tree problems requires a thorough knowledge of plants, botany, soil science, climate, horticultural practices, entomology, and pathology.

Symptoms (abnormalities)

Indicators of disease are leaf spots and blotches, stem dieback, cankers, poor growth, wilting, yellowing, and galls.

Causal Agents of Tree Stress

Causes of injury or disease can be either biotic or abiotic. Abiotic stresses (environmentally caused) would include nutrients, water, air, temperature, and salt stresses from excess fertilizer. Biotic stresses include insects, bacteria, fungi and viruses. Since many diseases spread from tree to tree, it is important to treat problems as they arise.

Leading Causes of Tree Stress

  • Over and under watering (The reason why a large percentage of new trees fail)
  • Over and under fertilization (Over fertilization can cause the soil to actually pull water out of the roots)
  • Physical root damage due to construction or building renovation
  • Poor soil quality 

Tree Care Tips

  • Water trees less frequently to make trees more drought resistant
  • Mulch to provide beneficial nutrients, shade the roots, prevent weeds from competing for water and nutrients (1 to 3 inches only)
  • Trim trees to promote a more efficient nutrient transport

Tree Construction Mitigation

We recommend hiring a Certified Arborist before you begin any construction on a new home, add an addition, or clear a building site. Most trees can be saved if one plans ahead and brings in a Certified Arborist at the start of the project. Often-times it is too late to save a tree after damage has been done. Several construction factors that lead to the slow decline or immediate death of a tree are:

Change in soil grade – causes loss of valuable microbes from the soil when the top layers are removed and roots suffocate

Soil Compaction – leads to root suffocation or can reduce water movement through the soil.

Mechanical Injury –  damages roots, and compacts the soil.
