Trees can be harmed—and even killed—by both biotic factors (such as humans, pests, bacteria, and competing plants) and abiotic factors (like drought, poor soil conditions, lack of sunlight, or water deprivation).

The first step in restoring your tree’s health is to identify the root cause of the problem.

Human Activity: A Common but Overlooked Threat

Surprisingly, many tree health issues begin with unintentional human actions. In fact, human interference is one of the leading causes of tree stress. Some of the most common problems include:

• Construction damage that disrupts or severs roots
• Soil compaction caused by heavy machinery or foot traffic
• Trunk injuries from lawn mowers or string trimmers
• Over-mulching, which can trap moisture and suffocate roots

These stressors can weaken trees, making them more vulnerable to pests and disease.

Recognizing the Signs of Tree Stress

Early signs of a stressed tree often include:

• Crown dieback (thinning or dead branches at the top)
• Leaf discoloration or premature leaf drop
• Stunted growth or smaller-than-normal leaves
• Cracking or peeling bark

These symptoms are frequently linked to abiotic stressors such as drought, high winds, poor drainage, compacted soil, or extreme temperatures. However, once a tree is weakened, it becomes susceptible to biotic threats—especially pests and fungal infections that rarely affect healthy trees.

Tree Diseases Can Spread Fast

Unfortunately, symptoms of tree illness are often subtle in the early stages. By the time visible damage appears, it may be too late to reverse the decline.
