Overgrown Roots

Overgrown Roots

Trees display a variety of outward symptoms that indicate a need for removal. Signs such as unnatural leaning, damaged limbs, or trunk, and/or rotted portions is when you call an arborist. But just as one should not judge a book by its cover, remember that more than a tree’s visible parts affect its health.

If you are concerned about the status of a tree on your property – including issues stemming from its roots – reach out to Advanced Arbor Tree Care. Our team provides professional and affordable tree care options. Clients appreciate the dedication and expertise that we bring to every project. Plus, our certified arborists begin each estimate by inspecting your trees and determining whether trimming may preserve them. They remove trees only when necessary.

Roots provide trees with many of their basic living necessities: water, oxygen, and minerals. All these things come from the soil, and its conditions affect root growth. So, a change in the soil’s conditions will affect the tree – and vice versa.

Several factors can influence these conditions: contaminants, heavy traffic, buildings, and so on. Although these are human-driven causes, people generally do not intend or realize their influence. Thus, our tree experts strive to teach our customers about proper tree care.

First and foremost, overgrown tree roots can disrupt nearby structures.

Damage or block pipes: though roots rarely break pipes, their growth can shift pipes’ positions and damage them. Plus, slight pipe ruptures release water and nutrients, which support further root growth.

Lift or crack pavement: anyone who has walked along a city block with large trees will have seen uneven concrete slabs upset by root growth beneath them. Roots can also crack or break sidewalks and paved roads.

Undermine foundations: while several events threaten buildings’ foundations, roots are occasional culprits. Small roots can grow into cracks but never cause significant damage. Roots may, however, soak water away from soil and lead to house settling.

Overgrown roots may also create hazards in your yard/property.

Surfacing roots: given their adjacent position to the surface, roots can sometimes break above ground. They become both tripping and lawn care hazards. It is a particular problem for areas prone to soil erosion and another reason to let professionals handle storm-damaged trees.

Exposure from regrading: a regular part of any lawn and landscape care, regrading can significantly change the surface of your yard. It may expose overgrown roots or cover previously-exposed ones and allow them to grow further. Either case can result in more surface roots.

Whether you suspect that one of your trees presents a danger or notice one that is down in your yard, call the tree care experts at Advanced Arbor. We offer mulching, stump grinding, emergency removal, and standard tree removal services.

Hurricane Ready Trees

Hurricane Ready Trees

Correct pruning is the most important part of helping trees survive hurricanes. Train young trees so they develop a sturdy, well-spaced framework of healthy branches along a dominant trunk. Maintain this form as far up into the tree as possible by reducing the length of competing stems and branches.

For trees larger than about 15 feet tall, hire a certified arborist (like Advanced Arbor!) to prune your trees before the hurricane season. The arborist will remove dead branches that can fall on houses, cars, and people. Overly long branches should be shortened and branches with cracks removed or shortened. Branches with the same diameter as the trunk will be shortened and the outer edges (not the interior) of the canopy will be thinned, making your tree less likely to be blown over. Low branches that are close to your roof should be removed or shortened, as well. Be sure to have your trees evaluated by Advanced Arbor annually.



Mulch moderates soil temperatures, keeping roots warmer in winter and cooler in the summer. It also helps sustain soil moisture, reducing the water needs of trees. Mulch inhibits weeds, helps reduce soil erosion, and can improve soil, which improves or maintains tree health. To take advantage of all of the benefits of mulch, follow these tips.

Maintain a 2- to 3-inch layer. Coarse materials, such as pine nuggets, may be applied to a depth of 4 inches, but don’t allow mulch to accumulate to a greater depth. Adding more mulch can harm trees because mulch intercepts rain and irrigation meant for plants’ root systems.

Avoid “volcano mulching.” When mulch is piled against the base of a tree, it holds moisture, encouraging rot in the trunk. It also encourages roots to grow close to the trunk, which can kill the tree if roots grow around the trunk.

Mulch to the drip line or beyond. The mulched area around the tree should be at least 8 feet in diameter. Remember that in a forest environment, a tree’s entire root system (which usually extends well beyond the drip line) would be naturally mulched.

Remove old mulch. Some mulches can become matted, preventing water and air from seeping through. Occasionally (every couple of years), you should remove mulch and soil that is against the trunk, together with any roots growing in the mulch. Remove old mulch before adding fresh mulch to the landscape.

Proper Tree Pruning

Proper Tree Pruning

Pruning trees selectively removes branches to provide clearance, reduce risk of breakage, or reduce size. When pruning, follow these steps, and then shred the resulting cuttings to add to the compost pile or use as mulch. (You can also toss the cuttings behind a shrub to decompose.)

Keep it healthy. Remove all dead, diseased, or injured branches.
Keep it strong. Remove or reduce the length of stems that compete with the main leader.
Keep it uniform. Remove branches that cross or touch each other and any that look out of place.
Keep it minor. You should only tackle minor pruning tasks in your landscape. Hire an arborist certified by the International Society of Arboriculture to prune trees taller than about 15 feet. Correct pruning makes trees more resistant to hurricane damage.
