Our Certified Arborists are certified by the International Society of Arboriculture. We provide a full tree inspection and gather the tree’s history from the customer when determining possible reasons for a tree’s decline.
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 defensive system against injury. Diagnosis of tree problems requires a thorough knowledge of plants, botany, soil science, climate horticultural practices, entomology and pathology.
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, and some diseases can spread to other trees in the area.
Leading Causes of Tree Stress
- Over and under watering (This is where 90% 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, adding an addition, or clearing 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 the tree after the damage has been done. Several factors that lead to a slow decline or immediate death of a tree due to construction are:
Change in soil grade – causes loss of valuable microbes from the soil when the top layers are removed and roots can suffocate if the grade is raised.
Soil Compaction – is a big problem on construction sites and can lead to root suffocation or can reduce water movement through the soil.
Mechanical Injury – from the movement of bulldozers and other heavy equipment that can gouge the tree bark, damage roots, and compact the soil.
