The Basics of Tree Life

Trees are complex organisms that rely on a delicate balance of biological processes to survive. Key components include:

  • Photosynthesis: The process by which trees convert sunlight into energy.
  • Transpiration: The movement of water through the tree from roots to leaves.
  • Respiration: The process of breaking down sugar to release energy.

Signs of a Healthy Tree

A healthy tree typically exhibits:

  • Vibrant Green Leaves: Indicative of active photosynthesis.
  • Flexible Branches: Signifying adequate hydration and nutrient flow.
  • Stable Root System: Providing support and nutrient absorption.

Dead Or Dormant

Determining whether a tree is dead or merely dormant can be confusing, but several straightforward methods can help clarify its condition. Here’s how you can assess the vitality of your trees:

1: Examine the Buds 

Trees produce new buds from their crown even in dormancy, serving as an indicator that the tree is not dead. These buds can vary in color—from brown to deep red—depending on the tree species. A lack of buds on the branches typically signals that the tree is dead.

2: The Snap-Snatch Test 

This test helps detect the presence of green cambium, a layer beneath the bark that remains vibrant in dormant overgrown trees. To perform this test, make a small incision in the bark with a knife to expose the cambium. If this layer is green, the tree is likely dormant; if it’s dry, the tree may be dead.

3: Inspect the Bark

 The condition of a tree’s bark is another good indicator of its health. Healthy trees periodically shed their bark to make way for new growth, while those in decline may fail to regenerate bark effectively.

4: Assess the Roots and Soil

 Damaged or rotten roots can doom a tree. To check the roots’ health, move aside some soil at the base of the tree. Look for signs of damage or fungal growth, which often presages the tree’s demise.

5: Inspect the Trunk 

The trunk is crucial for the tree’s survival, channeling water and nutrients from the roots to the branches and leaves. Check for warning signs such as cavities, cracks, splits, or missing bark, which could indicate serious health issues. Also, look for evidence of lightning strikes, such as a long strip of missing bark accompanied by browning leaves.

6: Additional Diagnostic Tests 

Further tests can include checking for deep cavities at the tree’s base, which might suggest internal decay, or looking for sawdust around the tree base, a possible indication of termite or ant activity which could lead to the tree’s collapse.

Is Your Tree Dead or Just Sick?

A healthy tree is typically strong and robust, yet it can deteriorate due to various environmental factors such as wind, rain, and extreme temperature fluctuations. While these conditions are beyond control, it’s crucial to monitor trees for any early signs of distress.

Regular inspections are essential for maintaining tree health, ideally once each season and particularly after severe weather events. Although a tree may exhibit a full, lush crown, appearances can be deceiving—trees can still be unwell even with green foliage. Here are some indicators of poor tree health:

  • Dead Wood: This appears dry, lifeless, and snaps easily. Unlike healthy branches that flex with the wind, dead branches are brittle and prone to breaking, posing significant hazards.
  • Cracks and Cankers: Vertical cracks through the bark can signal a tree’s decline, while cankers—areas where bark is absent—may lead to breaks near the affected area.
  • Weak Branch Unions: These occur where branches grow close enough for bark to develop between them, compromising the joint’s strength since bark is weaker than wood.
  • Decay: Often starting from within, decay can be hard to detect early on. Signs include fungal growth like mushrooms, peeling bark, and wood that feels soft or crumbly.
  • Poor Tree Architecture: Imbalanced growth, such as a tree leaning or growing lopsidedly, often results from storm damage or improper pruning.

If you suspect your tree is ailing, consulting with an arborist is advisable. Arborists are skilled in diagnosing tree diseases and can recommend appropriate interventions.

While not all diseased trees require removal, dead tree should be promptly taken down to prevent hazards. Tree removal should always be handled by professionals to ensure safety and prevent damage to property or people.

Saving a Diseased Tree

Preventing disease is always better than treating it, and this is especially true for trees, as a healthy tree is more resistant to disease. To maintain the health of your trees and help them thrive, consider these preventative steps:

  1. Avoid Weed Fertilizer Near Tree Roots: Fertilizers designed for lawns can harm trees if applied near their roots. These substances may interfere with the tree’s natural nutrient uptake.
  2. Proper Mulching: When mulching around a tree, leave some space around the trunk. This prevents the wood from rotting by allowing air circulation and reduces the risk of fungal infections.
  3. Careful Root Handling: If your tree has exposed roots, avoid damage by trimming these areas by hand. Avoid using lawn mowers or sharp tools around the roots to prevent cuts that could become entry points for pathogens.
  4. Watering During Droughts: In dry conditions, water your trees adequately as their roots may rise towards the surface in search of moisture, weakening the overall root structure and making the tree more vulnerable.
  5. Correct Pruning Techniques: Proper pruning is crucial for maintaining tree health. Incorrect cuts can expose trees to diseases. Since pruning requirements vary by species, consult a local nursery or a tree care specialist for guidance tailored to your tree type.

Neglecting these care steps can lead to severe consequences. For instance, Dutch Elm Disease (DED) has been particularly destructive, wiping out large populations of American Elm trees. This fungal disease obstructs the vascular tissues, preventing water transport within the tree. Elm bark beetles exacerbate the problem by breeding in diseased trees and spreading the fungus as adults move to new trees.

Moreover, once a tree is infected, the disease can quickly spread through interconnected root systems, potentially killing entire rows of trees. The lack of water supply eventually leads to the crown dying, causing the tree to wilt and ultimately die. By implementing these preventative measures, you can significantly reduce the risk of such devastating outcomes.

Trees can greatly enhance the beauty of your lawn when they are healthy and flourishing. However, if a tree begins to show signs of serious decline or death, it’s important to consider removing it for safety reasons. A dead tree poses several risks, including the potential to fall and cause damage to your property or neighboring properties, or even injure people or pets. The liability associated with a tree falling on a person or damaging property can lead to significant financial burdens, including costly repairs and medical expenses. 

Additionally, dead branches that drop from the tree could injure someone, damage vehicles, or knock down crucial utility lines. Given these risks, removing a dead tree is a necessary measure to ensure the safety and security of your home environment.

Can Dead Tree Roots Kill Your Grass?

Some trees develop roots that extend above the ground, which can create various problems. These surface roots can harm the surrounding grass by blocking sunlight and absorbing moisture, leading to patches of dead grass. Additionally, if these roots are in the path of a lawn mower, they can cause damage to the mower blades when struck.

Moreover, trees planted near sidewalks or pathways can pose a risk if their roots grow large enough to crack or uplift the pavement, creating tripping hazards for pedestrians. Neglecting to address surface roots can lead to more significant and costly issues over time.

To prevent these problems from escalating, it’s advisable to consult with a professional. A tree specialist or arborist can assess the situation and recommend solutions, such as safely trimming the problematic roots or adjusting the landscape to accommodate the tree’s growth while minimizing damage to your property and ensuring safety for passersby.

Why Should You Remove Dead Trees?
