Category: Tree Care Tips

October is one of the more useful months of the year for looking at your trees. As leaves thin out and drop, the structure of each tree becomes visible again. Cracks, dead limbs, odd lean, cavities, and fungal growth that were hidden under a full canopy all summer are suddenly easy to see from the ground.

That visibility matters because winter in our part of Maryland brings wind, heavy wet snow, and ice loading. A limb that was already compromised in October is carrying extra weight in January. Below is the fall tree inspection checklist we walk through on properties around Burtonsville, Silver Spring, and the rest of Montgomery County, plus a clear split between what a homeowner can reasonably handle and what belongs to a trained professional.

Why Fall Is the Easiest Time to See Tree Problems

Trees hide a lot behind their leaves. A full summer canopy can mask a dead leader, a split union, or a pocket of decay. Once leaves drop, you get a clean view of branch architecture, bark condition, and how the crown is balanced over your house, driveway, or play area.

Fall also gives you useful clues from the leaves themselves. Pay attention to how a tree dropped them:

• A section of the crown that browned and dropped leaves well ahead of the rest of the tree may have a root or vascular problem.
• Leaves that turned brown but stayed attached on one limb often point to a branch that died during the growing season.
• A tree that held green leaves much longer than its neighbors of the same species can also be a sign of stress worth watching.

Another fall advantage: the ground is often firm and the undergrowth has died back, so you can walk the base of each tree and actually see the root flare, the soil surface, and any mushrooms or soil heaving. In summer, groundcover and weeds hide all of that.

Start at the Base: Roots, Flare, and Soil

We always begin at the ground because root problems are the ones homeowners miss. Walk a full circle around each large tree and look for these things.

• The root flare. A healthy trunk should widen where it meets the soil, like the base of a wine glass. If the trunk goes straight into the ground like a telephone pole, soil or mulch may be piled too high against it.
• Mulch volcanoes. Mulch mounded against the bark holds moisture against the trunk and encourages decay. Pull it back so it forms a flat ring a few inches away from the bark.
• Mushrooms and conks. Fungal fruiting bodies at the base, on exposed roots, or on the lower trunk often indicate decay inside the wood. Note where they are and take a photo.
• Lifted or cracked soil. Soil heaving on one side of a tree, especially the side opposite a lean, can mean roots are moving. This is a serious finding.
• Cut or damaged roots. Think back to any trenching, driveway work, utility work, or grading near the tree in the past few years. Root loss shows up in the canopy long after the digging is done.

Many yards in the Burtonsville area sit on clay-heavy soil that drains slowly. After a wet stretch, saturated clay holds roots less firmly, and that combination of soggy ground and winter wind is a common factor in trees that fail.

Work Up the Trunk: Cracks, Cavities, and Lean

Next, look at the trunk from a few different angles. Standing in one spot hides a lot. We like to view each tree from at least three sides and from across the yard so you can judge the whole form.

• Vertical cracks or seams. A long split in the bark can indicate internal separation. Note the length and whether it runs into a major branch union.
• Cavities and hollows. Openings in the trunk are not automatically a reason to remove a tree, but the amount of sound wood remaining around the cavity matters.
• Bark that sounds hollow or sloughs off. Loose, peeling bark on a patch of trunk with no new growth underneath suggests dead tissue.
• Lean. A tree that grew with a lean is different from a tree that recently started leaning. New lean, combined with disturbed soil on the opposite side, deserves attention from a professional.
• Co-dominant stems. Two trunks of similar size splitting from one point, especially with dark, included bark pinched between them, create a weak union. Older maples, Bradford pears, and silver maples around here commonly show this.

Take photos with your phone as you go and date them. Comparing this October’s photos to next October’s is one of the simplest ways to track whether something is changing.

Look Up: Deadwood, Hangers, and What Is Over Your Roof

With leaves down, scan the canopy against the sky. Dead limbs stand out as bare, gray, often stub-ended branches with no fine twigs. Also look for hangers, which are broken limbs that did not fall all the way and are resting in the crown. Wind or snow can bring those down.

Then shift your attention from the tree to the target. Risk is about what is underneath. Ask yourself:

• What sits under the heaviest limbs? A roof, a deck, a driveway where cars park, a bedroom, a fence, a neighbor’s property?
• Do branches touch or rub the roof, gutters, or siding? Contact wears shingles and gives squirrels a path indoors.
• Are limbs growing into the service drop that runs from the pole to your house?
• Does the canopy block light from reaching your walkway or driveway, where ice can linger?

A dead limb over an unused corner of the back yard is a different situation than the same limb over a bedroom. That difference is exactly what a formal tree risk assessment is designed to sort out, by weighing the likelihood of failure against what would be affected.

What Is Safe for a Homeowner to Do This Fall

There is real work you can do yourself without getting into anything hazardous. All of it happens with both feet on the ground.

• Inspect and document. Walk the property, take photos, and write short notes on each tree. This record is genuinely useful when an arborist arrives.
• Clear the base. Pull mulch back from trunks, remove string trimmer damage sources, and clear piled leaves away from the root flare.
• Rake and manage leaf litter. Leaves under trees that had fungal leaf problems this season are worth removing rather than leaving in place.
• Water during dry fall stretches. Trees planted within the last few years benefit from deep watering until the ground freezes.
• Mulch correctly. A two to three inch layer of mulch, spread wide and kept off the bark, insulates roots through winter.
• Prune small, reachable stuff. Thin twigs and small suckers at ground level, cut with hand pruners while standing flat on the ground, are fine.
• Protect young trunks. Deer rub on thin-barked young trees in fall. Trunk guards help.

Here is the line we ask homeowners not to cross: no ladders, no chainsaws overhead, no climbing, and nothing near utility lines. Most serious homeowner tree injuries involve a ladder, a running saw, and a limb that moved in a direction nobody predicted. Standing under a limb to cut it also means standing where it lands.

When to Bring in a Professional

Call for a professional evaluation when your checklist turns up any of the following:

• Mushrooms or conks at the base, on roots, or on the trunk.
• A crack running into a major union, or two trunks with dark bark pinched between them.
• New lean, or soil lifting on one side of the tree.
• Dead or broken limbs above a roof, driveway, deck, or anywhere people gather.
• Any limb near the lines running to your house.
• A tree that leafed out thin, dropped leaves early, or has a dead section in the upper crown.
• A large tree that had construction, trenching, or grading near its roots in recent years.

At Hometown Tree Experts, we provide tree risk assessment, tree pruning, arborist service, storm damage tree service, lot clearing, and dumpster rental for homeowners in Burtonsville and the surrounding Montgomery County communities. A risk assessment looks at the whole picture: species and its typical failure patterns, the defects present, site conditions and exposure to wind, and what sits in the fall zone. From there you get options, which often include pruning to reduce weight on a weak limb rather than removing a healthy tree.

If your October walk turned up something that made you pause, write it down, photograph it, and reach out. Looking at a questionable limb in the fall, while you can still see it clearly, is a lot more straightforward than dealing with it after it has come down in a winter storm.
