Preparing Your Trees for Storm Season in Pennsylvania

Pennsylvania storm season is no joke for homeowners with mature trees. From late spring through early fall, fast-moving thunderstorms roll across Bucks County and Montgomery County with little warning, bringing straight-line winds that can snap limbs and split trunks in seconds. Summer derechos, microbursts, and severe thunderstorm warnings are common from Warminster to Lansdale and from Doylestown to Horsham. When those storms arrive, the difference between a tree that survives and one that crashes through your roof often comes down to preparation.

At McCreesh Tree Service, we see the aftermath of every major storm. We have cleared fallen oaks from driveways in Richboro, removed split maples from power lines in Willow Grove, and dismantled storm-damaged trees leaning against homes in Newtown and Blue Bell. The homeowners who fare best are the ones who prepared their trees before the storm arrived. This guide explains exactly what storm preparation looks like and why it matters.

If you live anywhere in southeastern Pennsylvania and have mature trees on your property, the time to prepare is now, before the next severe weather forecast.

Pennsylvania sits at the intersection of multiple weather systems. Warm, moist air from the Atlantic clashes with cooler continental air from the west, creating unstable atmospheric conditions that spawn severe thunderstorms, especially during spring and summer. Our trees have evolved to handle normal wind and rain, but severe storms deliver forces that exceed the structural limits of even healthy trees.

The suburban and semi-rural landscapes of Bucks County and Montgomery County add another layer of risk. Many neighborhoods were built around mature trees that predate the homes themselves. These trees grew in open conditions with balanced canopies and strong root systems. Then houses, driveways, sidewalks, and utility lines were added around them. The trees adapted, but their root zones were compressed, their canopies became asymmetric as they grew toward light gaps, and their structural balance was altered by decades of proximity to buildings.

Storm preparation is about recognizing these vulnerabilities and addressing them before the wind starts blowing. A properly prepared tree is not stormproof, but it is dramatically more likely to survive severe weather without catastrophic failure. And a prepared property is a safer property for your family, your neighbors, and your home.

Deadwood removal is the single most important storm preparation step for most homeowners. Dead branches are brittle, weak, and completely unable to flex under wind load. When a storm hits, dead limbs are the first things to break, and they often break into large, heavy pieces that can crush roofs, vehicles, fences, and anything beneath them.

A professional deadwood pruning removes all dead, dying, and detached branches from the canopy. This reduces the overall sail area of the tree, which is the portion of the canopy that catches wind and creates leverage against the trunk and roots. Less sail area means less force transmitted to the tree’s structure during high winds. It also eliminates the most likely failure points.

In neighborhoods like Southampton and Feasterville, where mature oaks and maples dominate the landscape, deadwood removal should be done annually or at minimum before every storm season. McCreesh Tree Service uses ANSI A300 pruning standards to remove deadwood without damaging living tissue or creating wounds that invite decay. Proper deadwood pruning makes the tree safer and healthier, not just less likely to fail in a storm.

Homeowners sometimes ask if they can just remove deadwood themselves. For small ornamental trees, careful hand pruning of obvious dead twigs may be fine. For anything larger than a shrub, professional deadwood removal is strongly recommended. Climbing mature trees with chainsaws, identifying hidden deadwood deep in the canopy, and making proper pruning cuts that promote healing are all skills that require training and experience. DIY deadwood removal on large trees is one of the most common causes of homeowner injury we see.

Canopy thinning is a specialized pruning technique that reduces the density of the tree’s crown without altering its overall shape or size. By selectively removing specific branches throughout the canopy, thinning allows wind to pass through the tree rather than hitting it like a solid wall. This dramatically reduces the wind load on the trunk and roots.

Thinning is especially valuable for dense-canopied species like Norway maples, Bradford pears, and some oak varieties that are common in Yardley, Langhorne, and Newtown. These species naturally grow thick crowns that act as sails in high wind. A properly thinned canopy lets air flow through the interior branches, reducing the total force pushing against the tree while maintaining the tree’s shade value and aesthetic appearance.

There is a right way and a wrong way to thin a canopy. Aggressive overthinning, sometimes called lion’s tailing, strips interior branches and leaves only foliage at the ends of limbs. This actually makes trees more dangerous in storms because the remaining branches become long, unbalanced levers. Proper thinning removes branches evenly throughout the canopy, maintaining the tree’s natural architecture while reducing density. McCreesh Tree Service’s certified arborists understand the difference and never compromise tree structure for short-term convenience.

Canopy thinning should ideally be completed in late winter or early spring, before trees leaf out and before storm season begins. This timing allows the tree to heal pruning wounds during the growing season and ensures the structural improvements are in place before the first severe weather event.

Branch unions are the points where two branches meet or where a branch attaches to the trunk. A strong branch union has a distinct collar of overlapping wood fibers that create a solid connection. A weak branch union, often caused by included bark, is a structural defect that makes the branch far more likely to split off in wind or ice.

Included bark occurs when bark becomes trapped between two growing branches, preventing the wood fibers from interlocking. From the outside, the branch union may look normal. But inside, the connection is essentially two separate pieces of wood pressed together without any real structural bond. When wind loads the branch, the weak union simply splits apart. This is one of the most common failure modes in storm-damaged trees.

Weak branch unions are especially common in certain species that are prevalent in our area, including Bradford pears, silver maples, and some oak varieties. They are also common in trees that have been topped in the past, because topping cuts stimulate multiple weakly attached shoots to grow from the same point. In Buckingham and Warrington, we frequently find weak branch unions in previously topped trees that were butchered by unqualified cutters years ago.

A certified arborist can identify weak branch unions during a pre-storm inspection and recommend appropriate action. Depending on the severity and location, options may include structural pruning to reduce weight on the weak union, cable and brace installation to reinforce the connection, or removal of the affected branch or the entire tree if the defect is too severe to manage safely.

Even with the best preparation, severe storms can damage trees. Knowing how to inspect your property after a storm helps you identify hazards that need immediate attention versus issues that can be addressed during your next scheduled maintenance.

Start with a ground-level walk-around of every tree on your property. Look for new leaning, soil disturbance around the root zone, fresh cracks in the trunk, and broken or hanging limbs. Check for branches that have fallen but gotten caught in the canopy rather than reaching the ground. These hanging limbs, sometimes called widowmakers, are extremely dangerous and need professional removal.

Examine the canopy from multiple angles. Look for sections where the crown appears thinner or damaged. Check major branch unions for fresh splits or cracks. Pay special attention to trees that are within falling distance of your home, garage, driveway, or power lines. A damaged tree in an open field is a lower priority than the same tree leaning toward your bedroom.

Document any damage with photos from a safe distance. These will be useful for insurance claims and for communicating with your tree service. Do not climb on ladders, roofs, or into the tree to get better photos. If you see damage near power lines, stay away and call your utility company immediately. If you see cracks, leaning, or hanging limbs, call an emergency tree service.

McCreesh Tree Service provides post-storm assessments across Bucks County and Montgomery County. We can evaluate storm damage, stabilize immediate hazards, and recommend follow-up care to restore your trees to safe condition. Our emergency response team is equipped to handle everything from single hanging limbs to multi-tree storm disasters.

The most effective storm preparation is not a one-time cleanup before the forecast. It is an ongoing relationship with a professional tree service that understands your property and keeps your trees healthy year after year.

Regular pruning maintains strong branch structure, removes developing problems before they become emergencies, and keeps trees in balanced condition. Annual inspections by a certified arborist catch issues like early disease, pest infestations, and subtle structural defects that a homeowner might miss. Soil management, mulching, and proper watering support root health, which is the foundation of storm resistance.

McCreesh Tree Service works with many homeowners on annual maintenance programs. We visit in late winter to assess each tree, perform necessary pruning, and identify any trees that should be monitored or scheduled for future work. This proactive approach costs far less than emergency removals and property repairs, and it keeps your trees looking beautiful and healthy in every season.

If you are a homeowner in Warminster, Doylestown, Lansdale, Horsham, or any nearby community, consider establishing an annual tree care plan. Your trees will be safer, healthier, and better prepared for whatever Pennsylvania weather sends their way.
