What To Do About “Hangers” In Your Tree?

Recently our area has experienced multiple severe wind events. You may have noticed some light to moderate damage to some of the trees in your yard. You may have even experienced severe damage or a complete failure of a tree on your or a neighbor’s property. While a complete failure or severe damage pose obvious hazards and need removal, it is the more minor to moderate damage that often raises questions on how to address the issue. Hanging broken branches are often called “Hangers” in forestry or tree care circles. These are often smaller to mid-sized branches which have partially broken off but are still lodged in the tree. After several weeks to a month the foliage starts to die and turn brown, and these “hangers” become obvious in trees that received damage. How do you assess these and when should you get a professional involved? Do they pose a potential health issue if not removed?

These broken limbs are becoming quite noticeable as they die and turn brown. It is important to make good decisions on how to handle these hanging dead branches and how to maintain your tree. Often these hangers are more unsightly than anything else, especially if they are small. Larger ones may pose a risk of damage or injury if they are located over a structure or may fall in an area frequented by people. Most of these hangers will break and dislodge over time, especially in wind events. You should consider the risk posed by the hanging limb, the difficulty and cost of addressing it, and the risk posed by the limb falling. For trees that got noticeable damage with several larger limbs broken, having some repair and rejuvenation pruning done is often good for tree health. You may be able to address some issues yourself if you are handy with a pole pruner and the broken limb is in reach. Anyone attempting even light tree work should be aware of risks posed by falling limbs and use of pole saws. Remember to never attempt to climb trees yourself or perform tree trimming from a ladder or height, as this is fundamentally unsafe. Even limbs which may be safely reached from the ground with a pole pruner can pose risks of injury. If you are attempting to remove some of these hangers with a pole pruner, be very cautious and use good safety techniques. You need to make sure the branch has a landing zone, and you are well clear of it when using a pole saw or pruner. Be aware of vines and other entanglements, and do not work around or within the right of way of electrical or other lines. Larger limbs and those not reachable from the ground should be considered outside the scope of homeowners and left to professionals.

Here is a quick reference guide for how to size up any broken or damaged limbs in your tree and address the situation

  1. Small branches and branch tips with a diameter of the broken branch is 1 inch or less and the branch is hanging or lodged. These size hangers pose little risk and are mostly unsightly. They should fall out of the tree on their own over time. These may be trimmed out slightly behind the break of those within reach of a pole pruner.
  2. Small to Medium branches-1-3 inches in diameter. The branch has partially broken or has completely broken and is lodged in another branch. Branches this size can do some light to moderate damage if they fall on a roof, fence, or other structure. If the branch overhangs areas where people or pets frequent it could cause injuries if it fails. If the branch does not pose a hazard or danger it should dislodge on its own over time. Consider removing these if they pose a risk. They can be removed from the ground with a pole pruner or pole saw but be very cautious as branches this size can easily injure someone that is in the fall zone. Consult a professional if a lift or climbing is required.
  3. Large Canopy Branches 3 inches and larger. These are significant branches and can hold a significant amount of weight. If they are partially broken, hung, or lodged in the tree they may come out at any time and do significant damage or cause injury. These branches are beyond the tools and scope of homeowners, and the damage may require some recovery pruning to keep the tree healthy. Consult with a professional and consider having the damage removed and tree properly trimmed.
  4. Main Branch and Trunk Failures- This is significant damage to the tree which can make it unsound or susceptible to disease in the future. If large main branches have failed, the top has completely failed, or part of the trunk has cracked or split from the damage; major damage has occurred and the tree may not recover. If your tree has suffered this level of damage consult a professional with a tree service and have a certified arborist examine the tree.

It can be hard to tell from the ground what level of damage a tree sustained until the brown foliage appears past the break. Once you can identify what type of damage occurred you can better determine what action is needed. For small branches it may be best just to wait for them to come out naturally or prune them out if this can be done safely with a pole pruner. For larger branches or more severe damage a professional is the best bet. For those hangers that pose a risk to structures or people in an area removal is best, as these could fall at any time and cause damage or injury. Remember never to attempt tree work yourself especially if it involves climbing or working from heights. You can find a certified arborist at www.treesaregood.org to address large limbs and significant damage. A good arborist can help you rehabilitate a tree that has had only moderate damage from a storm. If you are unsure of where to start with a tree that has wind damage, consult your local extension office for some advice.

Selecting Wind-Resistant Trees for Hurricane Season

Selecting Wind-Resistant Trees for Hurricane Season

The Pensacola area has had its fair share of rough weather lately. While the recent storms were not hurricanes, the rainfall totals rivaled many tropical storms, and the lighting and wind were disastrous. A tornado caused significant damage, including a tragic death, with more tumultuous weather in the forecast. Our rainy hurricane season has just begun, so it is worth talking about tree selection, management, and preparing for storms.

After the busy 1992, 1995, 1998, and 2004-05 hurricane seasons, several University of Florida researchers undertook an exhaustive on-the-ground project to look at tree damage statewide. Their goal was to determine which species survived high winds, and which trees were the most vulnerable during storms. Their findings were consistent, and have held up over the past few decades. A full description of the project can be found online, along with several publications that go over proper pruning and maintenance of trees, both before a storm and after recovery.

For the “coastal plain” of north Florida, the most wind-resistant species are: live and sand live oaks (Quercus virginiana/Q. geminata), American holly (Ilex opaca), Sabal palm (Sabal palmetto), Southern magnolia (Magnolia grandiflora), bald cypress (Taxodium distichum), Florida scrub hickory (Carya floridana), dogwood (Cornus florida), sweet gum (Liquidambar styraciflua), and crape myrtle (Lagerstroemia indica). The live oaks and sweet gums do have a tendency to lose branches, so it is important to undertake proper pruning in the off season to trim up potential problem limbs.

Live oaks, and sand live oaks (which live on coastal sand dunes) are slow-growing trees with extraordinarily dense wood. This protects them in hurricane-force winds. Part of the working theory on why bald cypress, holly, and magnolia do well in storms is their pyramidal shape, which seems to allow wind to whip circularly around the trees and avoid damage. Sabal palms are botanically considered part of the grass category and not trees, so their single, flexible trunk allows them to handle the onslaught of wind. Sweetgums are particularly hardy in tornadoes, due to their sturdy root system and shorter, “stout” branches. Smaller understory trees like crape myrtle and dogwood are likely dodging the strongest winds, but also have strong branch structures and dense wood. These two species, along with sand live oak, also lost an average of more than 80% of their leaves. This defoliation is an adaptation to heavy winds, with trees that lost leaves performing better overall than species that held onto their leaves but toppled at the trunk.

The least wind resistant species, according to the studies, included: sand pine (Pinus clausa), loblolly pine (Pinus taeda), and spruce pines (Pinus glabra)laurel and water oaks (Quercus laurifolia/Q. nigra), Southern red oak (Quercus falcata), Southern red cedar  (Juniperus silicicola), Carolina laurelcherry (Prunus caroliniana), black cherry (Prunus serotina), Loquat (Eriobotrya japonica), pecan (Carya illinoensis), sycamore (Platanus occidentalis), tulip poplar (Liriodendron tulipifera), Bradford pear (Pyrus calleryana), and red maple (Acer rubrum). A couple of pine species—slash and longleaf—performed in the medium range. In my experience post-hurricane, many of these trees that survived were stressed and ended up with pine bark beetle infestations. Water and laurel oak are common trees in Florida home landscapes, but typically have much shorter lifespans than live oaks. They are faster growing but have weaker wood, and are vulnerable to storms.

Another list of tree survivability was developed for residents in tropical and subtropical regions of the state. If you have friends or family in south-central Florida, be sure to share this information with them.

Besides planting wind-resistant species, the research team shared other observations related to tree planting and arrangement, too. Single trees are more vulnerable than trees planted in clusters, as they protect each other from incoming winds. Older trees, and those with preexisting damage, are more likely to fall. Trees with plenty of space around their roots do better—if a tree is surrounded on two or more sides with buildings or other hard surfaces, they cannot spread adequately. Detailed information on identifying damaged or poorly structured trees, along with maintenance and pruning tips, can be found in the “Urban Forest Hurricane Recovery Program” series of articles written by the UF tree specialists involved in the studies. The publications include good diagrams and photos of specific examples.

Tree Removal…After the Storm

Tree Removal…After the Storm

Moderate to strong El Nino conditions were predicted for this summer and I think this revelation has come true. The heat and humidity in the latter part of June were on the verge of being unbearable and the precipitation cycle is unpredictable. In the middle of the month, a series of storms with strong winds hit a number of areas in the panhandle, bringing down some large trees. University of Florida/IFAS Extension recommends removing large branches and trees that pose a threat to damaging your home and other structure before the start of each hurricane season. However, sometimes we just don’t get around to removing these trees until after they fall.

Luckily only the tops of the trees in the photo above fell on the roof of the house. These are laurel oaks (Quercus laurifolia) which are fast growing but not tolerant of wind. In this situation, four trees fell together and are laying on the corner of the roof. The trees also pulled down the power, cable, and phone lines to the house.

So where do we go from here? Unfortunately the trees were uprooted and pose the potential for additional harm to the house if not removed correctly. In this situation, a tree service that owns a crane was recommended to remove the trees without administering more damage to the home and other trees and plants in the landscape and to avoid knocking down the powerlines again.

The tree service utilized a boom lift and a crane to safely lift the trees away from the house and utility lines. The employee on the lift connected each section of the tree to the crane before each cut. The boom was then moved to a safe location before each tree section was lifted away to the road to be cut into smaller pieces.

In this situation, the homeowner was lucky. There was no damage to the house other than a couple bent panels on the metal roof. However, this little bit a damage could have been totally avoided if these weak trees had been removed before the storm hit.

The trees featured in this article fell during a thunderstorm and possible tornado. If these trees had fallen during a weather event that was Federally declared, then a portion of the cost for their removal and cleanup might have been eligible to be considered an itemized deduction on Federal income tax forms.

Nuttall Oak – A Great Shade Tree for Panhandle Yards

Nuttall Oak – A Great Shade Tree for Panhandle Yards

After Hurricane Michael indiscriminately felled millions of trees in the Florida Panhandle five years ago, I’ve gotten much more selective with which trees I recommend to shade-seeking homeowners.  Category 5 hurricanes don’t strike every year, or even every decade, but Michael reminded us that 150 mph+ wind events are possible, and we should choose the trees we plant accordingly.  Keeping Michael’s lesson in mind, the shade tree I’ve recommended most to area homeowners lately is the ultra-wind resistant Nuttall Oak (Quercus texana) *.

While probably not native to our area (Nuttall is native to Mississippi River Valley bottomlands and nearby Gulf Coast regions), Nuttall Oak is a well-adapted deciduous oak species perfect for the Panhandle.  The species is a strong, long-lived tree, yet also a quick grower (3-4’ per year in its youth, reaching 60-80’ at maturity).  Unlike many rapidly growing trees, Nuttall is extremely resistant to wind breakage, disease, and other disfiguring issues.  There are several Nuttall Oaks in Panhandle landscapes that survived Michael’s fury completely intact, with little more than wind-whipped leaves as evidence a storm had passed.

Nuttall is also an awesome landscape ornamental and a wildlife magnet in maturity.  The species possesses a strong central leader and a stately, upright-rounded appearance.  In summer, Nuttall leaves are large, dark green, deeply lobed, and pointed, somewhat reminiscent of our native Southern Red Oak.  In fall, trees are capable of Blue Ridge quality color with fiery orange-red foliage, though the foliage show is not as consistent year to year here as farther north.  The bark of Nuttall even has aesthetic appeal – dark and smooth in youth becoming ridged/furrowed with age.  And it’s not just people that find Nuttall attractive, several beneficial insects use Nuttall as a host plant and various wildlife (deer, squirrel, and ducks especially) are fond of the prolific, highly nutritious acorns that mature trees produce in earnest each winter. 

Finally, Nuttall is among the easiest of trees to grow and thrives in a variety of landscape conditions.  Because it’s adapted to grow in poorly drained bottomlands that are either seasonally flooded or very dry, Nuttall is very tolerant of both compacted, poorly aerated soils common in urban areas and unirrigated, often droughty soils present in many Panhandle landscapes.  However, like any tree, Nuttall Oak performs best with regular water and fertilizer for the first couple of years until established.

If you’ve been searching for a native-ish, hurricane-resistant, quick-growing, low-maintenance, wildlife-attracting shade tree for your property, Nuttall Oak is an excellent option and one I can fully recommend!  For more information on Nuttall Oak or any other horticultural topic, please contact your local UF/IFAS County Extension Office.  Happy gardening!

*Nuttall Oak was recently reclassified botanically from Quercus nuttallii to Quercus texana.

Which are the Sturdiest Trees?

Which are the Sturdiest Trees?

Florida’s state observance of Arbor Day falls on January 21st in 2022. On this day, people are encouraged to plant trees and recognize their importance. Trees provide us with shade and shelter, filter air and water, and increase biodiversity as well as acting as a source of materials for building and industry. Half of Florida’s land area is forested and North Florida has a large timber industry. Given the importance of trees to our wellbeing and the erratic and sometimes extreme weather in our region, the question occasionally arises, “What trees are best to plant here?”.

The answer to that question depends heavily on the needs of the person asking it. A landowner looking for long-term profit from forestry may choose to plant longleaf pines, despite the risks that hurricanes pose. A homeowner desiring a shade tree, however, might want a different answer.

There are plenty of varieties of trees that grow well in the panhandle of Florida, and the further one lives from coastal areas, the greater the options. Particularly along the shores, however, choices are limited by soil types, exposure to high winds, and even salt spray. So which are the toughest and hardiest trees for our area?

A sabal palmetto.

Florida’s state tree is the sabal palmetto. Also called the cabbage palm, this palm is particularly cold tolerant, withstanding temperatures down to 15º F. Once established, they are drought tolerant and fairly resistant to pests and diseases, as well as being particularly sturdy in high winds. Though they may be thought of as “common”, this is a testament to their survivability in our climate and they should not be dismissed as an option for landscapes.

A large, old Southern live oak.

Both the Southern live oak and especially the sand live oak are exceptionally survivable trees. Sand live oak is found closer to the coast, where it tends to grow in beautiful multi-trunked forms slightly inland, or in lower thickets along the dunes. It tends not to reach the same heights as Southern live oak, but does well in the harshest of

conditions, lasting through almost anything nature can throw at it. Even if defoliated by heavy storm winds, these trees survive. Hurricanes claim only the occasional live oak that catch enough wind to uproot and topple the entire tree, which is not a common occurrence.

 

The bloom of a Southern magnolia.

Southern magnolia comes in many sizes, from huge old specimens to more compact cultivars such as ‘Little Gem’, which can be trained to grow as hedges. Tolerating a wide range of soil moisture, these trees are rarely harmed by disease, though scale insects often take up residence on their leaves (which rarely seems to bother the trees, even if infestations are heavy). With gorgeous and fragrant blooms in the springtime, Southern magnolia stands up in high winds and makes an excellent addition to a landscape.

For more information on trees that do well in storms, see our EDIS publication on the topic. Also note that native species, trees that are properly pruned, those that are well established as opposed to newly planted, and trees free of disease or damage tend to survive better in any case. Ensuring that plants of any sort are placed in the right spot can serve the landscaper well in the long run as well – see the Florida Native Plant Society’s website for help in choosing the right plants. As always, your local Extension office is available to assist with questions as well.
