Like comfortingly aged family members, mature trees grace our properties with their beauty and familiarity. But just as aging bodies require diligent health monitoring, so too do our aging arbor friends.
Without careful inspection, hollowed trunks and damaged limbs go unnoticed, posing hidden home hazards. Just one falling branch during a storm can mean a crushed roof, damaged car, or injuries.
By identifying the red flags and warning signs of compromised tree health, we can take action before calamity strikes. Through vigilant monitoring and care, our wise old trees can continue thriving for years to come, without putting property and people at risk.
This guide will highlight what to look out for, so you can keep your home safe and preserve your aging green guardians. Read on and you’ll know precisely when to call in the arborist cavalry.
Hollowed Trunk and Decay
Like a rotten tooth, the hollowed trunk of an aging tree signals decay within. Fungal growths sprouting on the bark are another giveaway. If left unchecked, the fungi feast on moist wood, creating instability.
Trees with advanced internal decay become prone to dropping branches or even snapping entirely in strong winds. The cracks and crevices provide the perfect access point for pests and pathogens too. Stop them before they infest the whole yard.
- Check the base of trees for mushrooms, conks, or shelf fungi emerging from cracks or wounds.
- Examine the trunk all the way around, looking for small holes or soft spots that you can push a finger into.
- Listen for a hollow sound when tapping on the trunk with a hammer.
Cracks in Bark
Jagged cracks in a tree’s bark that penetrate deep into the trunk or major branches spell trouble. Unlike shallow fissures from normal growth, these run vertically down the trunk or branch.
While not an immediate threat, the cracks signal structural instability and expand over time as the tree sways. Eventually they create a breaking point, much like a crack in a sidewalk steadily widening. Look for splintering or flaking bark around the edges.
- Check for vertical seams with partially detached bark that you can slide a tool into.
- Examine areas where branches meet the trunk for vertical cracks spreading upward or downward.
Branches Growing Outward
Branches extending straight out from the trunk or other branches, rather than growing upward, indicate structural weakness. They are more likely to break and fall, especially loaded with leaves or snow.
Upward growth shows a tree’s natural strength while horizontal growth is a red flag. Branches growing sideways cannot adequately support their own weight long term. When they do collapse, they often take down other connected branches too.
- Look for long, straight branches sticking out at 90 degree angles from the trunk or other major branches.
- Check for V-shaped forks, which tend to split easier than U-shaped branch attachments.
- Branches that sag or droop could be a prelude to complete failure.
Damaged Roots
A tree’s extensive root system is its foundation and support network. But roots weakened by soil erosion, damaged during construction, or choked by weeds can render a tree unstable.
Without healthy anchoring roots, trees can lean or even topple over completely. Underground root rot is harder to detect but can also undermine the root system’s strength.
- Look for trees leaning to one side, which signals anchoring roots in that area are compromised.
- Check for mushy soil or depressions around the base, indicating root or soil issues.
- Have an arborist inspect if the ground rises around a tree, which may mean obstructed surface roots.
Leaning Trunk
A visibly leaning tree trunk is a red alert, signaling extensive root damage. The tree is already being pushed beyond its physical limits. Add the weight of leaves and rain, and collapse is imminent.
Even a slight lean indicates a major imbalance or loss of anchoring strength on one side. It’s unsafe to simply remove branches from the heavier side and call it a day. For a leaning tower of tree, removal is the only permanent solution.
- Use a level tool to determine if the trunk deviates from perfectly vertical at all.
- Stand away and view the tree from multiple angles, looking for any tilting silhouette.
- Have an arborist do an internal inspection for decay that may be causing the lean.
Dropping Limbs and Clumps
Scan the ground around your trees. Do you see sticks, clumps of leaves, or other debris accumulating? Like red flags, these droppings signal dying branches that could fail and fall without notice.
Dead wood high up is difficult to spot from the ground. But mounds of debris below offer clues, especially just after storms. Don’t ignore the warning signs right at your feet.
- Notice new piles of sticks that are living branches snapped by high winds or the weight of snow.
- Look for clumps of leaves that fell early, indicating dying branches.
- Keep yard areas tidy so fresh debris stands out clearly after storms.
With vigilant monitoring and proactive care, your wise old trees can thrive for years while staying sound. But at the first signs of trouble, take steps to restore their health or remove hazards. The seasoned warriors guarding your home deserve both affection and protection.
