Tree Diagnosis

Insect ~ Disease ~ Injury Diagnosis

A thorough diagnosis can best determine a plan to invigorate your trees to prevent or defend themselves from further injury.
Diagnosis of tree problems requires a thorough knowledge of plants, botany, soil science, climate horticultural practices, entomology and pathology.

Symptoms (abnormalities)
Leaf spots and blotches, stem dieback, cankers, poor growth, wilting, yellowing and galls

Causal Agents of Tree Stress
The causes of injury or disease can be both biotic or abiotic and more importantly if it is infectious.

Abiotic stresses would include nutrient, water, air, temperature and salt stresses. Biotic stresses would include insects, bacteria, fungi and viruses to name just a few.

Some Leading Causes of Tree Stress

• Over and under watering
• Over and under fertilization
• Physical root damage due to building renovation etc.
• Poor soil quality

Tree Care Tips

• Water during a drought
• Provide nutrients and a good rooting environment through mulching
