Like other trees and shrubs, crape myrtles in North Texas are not adapted to hard freezes like we had in February 2021. However, crape myrtles are hardier than many other area plants, and should recover completely, although they may bloom a little late.

Don’t Give Up on Your Crape Myrtles: WAIT!

Like with live oaks, we will have to wait a few weeks to know how crape myrtles handled the freezing weather. Even though they survived the freeze, the cold temperatures were a shock to the trees’ systems, and recovery takes time.

• We expect to see crape myrtles budding and leafing out 2 to 4 weeks later than usual.
  • May be less new growth and fewer buds
  • If the trees were healthy before the freeze, should recover completely.
• We recommend leaving new sprouts growing from the base until the crape myrtle is blooming normally.
  • If there are dead trunks, these sprouts can grow to replace them.
• Keep an eye out for common crape myrtles health issues as the trees recover from the freeze:
  • Aphids
  • Crape myrtle bark scale
  • Sooty mold
  • Powdery mildew
• If crape myrtles have shown no new growth by the end of April:
  • Remove all dead wood down to the highest level of living tissue
  • May need to trim down to ground level and let sprouts replace all trunks
• If your crape myrtles survived the frost, consider a plant health care program to keep them healthy
• Finally, as always, DO NOT TOP CRAPE MYRTLES!
  • For guidance on proper trimming, consult an ISA Certified Arborist

At Texas Tree Surgeons, we love trees and we love our community! The freezing weather in February 2021 will continue to have effects on area trees for years to come. Frost-damaged trees will need extra care and attention. We offer conprehensive plant health care programs that help stressed trees get the nutrients they need and fight pests. Our staff of ISA Certified Arborists are available to assess your trees and see if they need immediate action, or if it is best to wait and see how they recover. For questions about crape myrtles or any other tree, get in touch!

Can Palm Trees Survive Being Frozen?

Another installment in our series of posts where Texas Tree Surgeons answers your tree questions. Are you having problems with your trees and want to know what’s wrong? Let us know!

I sometimes hear the term “tree doctor;” is that a real thing?

We are used to going to the doctor when we are sick. We go to the dentist for our teeth, and take our pets to the veterinarian, but what about our trees? Is there such a thing as a “tree doctor?” How can I find a “tree doctor” near me?

Luckily, there are “tree doctors,” and like human doctors, they have to undergo education, have experience, and can have certain specializations. Also like human doctors, “tree doctors,” called “certified arborists,” rely on many other professionals to provide the highest standard of care.

What is a Tree Doctor?

• In the tree care industry, “tree doctors” are called “certified arborists.”
  • When we use the term “certified arborist,” we mean a tree worker with a specific set of skills and training.
• The organization that sets the standards for arborist certification, like the licensing boards for physicians, is called the International Society of Arboriculture (ISA).
  • The ISA has chapters all over the world, and covers every state in the US.
• In order to be certified by the ISA, an arborist must demonstrate experience caring for trees, pass a written exam, and earn a certain amount of continuing education credits.
  • Certification must be renewed every three years.

If ISA Certified Arborists are tree doctors in general practice, then ISA Board Certified Master Arborists are like specialists.

• To become a master arborist, one must be a certified arborist for a certain number of years or have a degree in arboriculture, forestry, or a related field.
  • On top of that, one must have demonstrated experience as an arborist for a period of time, pass a difficult written exam, and be individually approved by the ISA Board of Examiners.
  • To maintain board certification, the master arborist has to complete extensive continuing education in different subject areas every three years.

What Does a Tree Doctor Do?

Certified arborists are trained in all aspects of tree care, including proper trimming, health assessments, pest and disease diagnosis, watering and fertilization, planting, and basic tree safety protocols.

• Depending on their particular job, an arborist may have more experience in one area than another, or may have additional skills, like tree climbing.
• In general, certified arborists should know how to trim a tree to keep it healthy; how to identify diseases, pests, or stressors that might be affecting the tree; and when to recommend removal for safety reasons.

In addition to the fundamentals of tree care, some certified arborists attain further credentials in a specific area.

• An often-studied subject is how to identify and manage safety risks related to tree breakage or failure.
  • The ISA has established the Tree Risk Assessment Qualification (TRAQ) as a way for certified arborists to demonstrate their knowledge in this area.
• The Texas Chapter of the ISA has also created the Texas Oak Wilt Qualification (TOWQ) to recognize certified arborists who are trained in the identification and management of the virulent oak wilt disease.
• Additionally, there are qualifications available for specialized tree workers, for safety specialists, and for arborists who work around dangerous power lines or perform municipal work.

Will A Tree Doctor Trim My Trees?

While all ISA Certified Arborists should understand proper tree trimming for health and safety, that does not necessarily mean that it is the arborists themselves who do the actual trimming or other tree work.

• In the case of larger, more established tree care companies, certified arborists will establish protocols and methods for tree care.
  • Guidelines for tree care are published by the ISA, the Tree Care Industry Association, and other professional associations,
  • The instructions of certified arborists will be executed by trained tree workers, who may not hold arborist certifications themselves.
• Similarly, if trees need fertilization or pest control, the individuals who apply the products are usually experienced in the application process, not the diagnosis.

It may be helpful, again, to compare a “tree doctor” to a medical doctor. In most cases, especially in a larger clinic or hospital setting, the primary care doctor will diagnose an illness or condition and write orders for further testing, prescriptions for medications, or referrals to specialists.

• Certified arborists oversee the entire process of care for a particular tree, deciding on a course of action.
  • From there, the certified arborists assign certain tasks to certain other team members who are experienced and trained in that area.
• The tree climbers and other tree workers are like the physician’s assistants and medical technicians who perform the specific tasks of patient care.
• The plant health care technicians are like the pharmacists who distribute medication.
• Certified arborists even have access to a lab for performing tests on samples — in Texas, the experts at the Texas Plant Disease Diagnostic Laboratory provide lab services for arborists all over the state.

Nurses and patient care professionals are tasked with the day-to-day activities of treating disease, and the diverse members of a tree care team each have a particular set of skills that lead to trees receiving the highest level of care.

Do Tree Doctors Know Everything About Trees?

Additionally, just as medical doctors recommend second opinions or refer patients to specialists, effective certified arborists consult with others in their field to offer better tree care. As mentioned before, master arborists have a greater depth of knowledge and experience in many areas, and can provide support to other arborists as well as primary tree care themselves.

• Certified arborists with a credential in a specific disease or in tree risk assessment may be asked to consult on a particular project.
• In some instances, such as when a tree’s monetary value is in question, even master arborists may seek the services of an American Society of Consulting Arborists registered individual who has received training in the area of tree valuation.
• Ultimately, the best certified arborists in your area may not individually have detailed knowledge of every particular of tree care, but they should know how to find it.
• When you are considering hiring an arborist, be sure to ask about what resources (experts, labs, etc.) they use to diagnose and care for trees.

Like a trustworthy medical doctor, a reliable tree doctor knows when to ask for help, to make sure your trees are expertly cared for.

At Texas Tree Surgeons, we are proud to employ ISA Certified Arborists and Board Certified Master Arborists holding both Tree Risk Assessment and Texas Oak Wilt Qualifications. Our arborists are committed to continuing education and growing in the knowledge and practice of their profession. Our full-service tree care team includes experienced crews who train under an ISA Board Certified Master Arborist, Texas Department of Agriculture Licensed Applicators who apply our plant health care products, and a diverse support staff who handle all aspects of our locally-owned and family-run business.

Another installment in our series of posts where Texas Tree Surgeons answers your tree questions. Are you having problems with your trees and want to know what’s wrong? Let us know!

The leaves on our oak trees are looking diseased, with bumps all over them. Is this oak wilt?

Oaks are the most common trees in our North Texas urban forest, and they can suffer from many different health issues. If your oak is showing misshapen leaves with bright green bulges on them, it is most likely a fungal disease that may look bad, but is not usually harmful to the overall health of the tree.

Oak Leaf Blister 

• Oak leaf blister is caused by the fungus Taphrina caerulescens, which enters the new leaf buds during cool and moist spring weather.
• The fungus causes the young leaves to develop blister-like bumps on their surfaces, with coloration ranging from light green to brown.
  • In more severe cases, the leaves may fall off altogether.
  • The fungus does not affect mature leaves, only new growth.
• Like other fungal diseases, oak leaf blister is more prevalent during periods of cooler weather with increased rainfall in the spring, and cannot survive the summer heat.

Does Oak Leaf Blister Kill the Tree?

Oak leaf blister and the T. caerulescens fungus do not pose a serious risk to the health of affected trees.

Can Oak Leaf Blister Be Treated?

• The spores which carry the oak leaf blister fungus are present on the bud sites over the winter, and once the tree begins showing infected leaves, chemical treatment is not effective.
  • It is possible to apply a preventative fungicide, but this must be done before bud break and while the young leaves are maturing.
• If you have a tree with oak leaf blister, the best course of action is to clean up fallen infected leaves and dispose of them in plastic bags.
  • Do not place leaves in compost, as this may encourage further fungal growth.
• Keeping a tree healthy with proper mulching and fertilization, as well as maintaining soil drainage, will help it resist future health issues.

At Texas Tree Surgeons, we love trees and we love our customers! While oak leaf blister can be unsightly, it is mostly harmless and is not a serious concern to the health of the tree. Of course, there are many oak health issues that can cause long-term damage and tree death. Oak wilt is a major concern. Trimming oaks should be avoided between February and July if possible, and proper precautions taken if trimming cannot be postponed. Oak decline is also a problem, especially in areas where many of the trees were planted around the same time, and are reaching the end of their lifespan. If you have any questions about the health of your oaks, or any other tree care issues, let us know!

Tree trimming or tree pruning in Texas is generally best when done after temperatures cool off in the fall and before buds begin to grow in the spring. Removal of dead, broken, or damaged limbs can be done anytime. The worst time to trim a tree is in the spring just after it has budded out. The tree will already have used its energy to start new growth, and will not be able to recover from the trimming as well or as quickly. At Texas Tree Surgeons, tree trimming is the most common service we provide, and is essential to maintaining health and safety in our urban forest.

Why is it best to trim trees in the fall and winter?

Trimming trees at the right time is crucial to keeping them healthy. During the fall, the tree’s internal systems begin to slow, as it prepares to go dormant (similar to hibernation in animals). Entering a dormant state helps the tree survive the winter cold, frost, and ice. As the weather cools, the water in tree tissue begins to be converted to starch, which insulates cellular tissue against freezing damage. During this period of dormancy, trees are able to heal the wounds made from pruning before the stressors of spring, like disease and insects, arrive.

Proper trimming is not just a matter of timing, however, but also of technique. Trimming your trees at the proper time in the fall or winter cannot compensate for the damage done through over-trimming, lion-tailing, or topping. Even though a dormant tree can better withstand these damaging types of trimming, the overall health of the tree may be irreparably harmed.

Why is it important to use a company with certified arborists to trim your tree?

Every tree is different. Two trees of the same species planted next to each other may still react differently to their surroundings. Having an ISA Certified Arborist examine your trees before trimming is crucial to ensuring proper care. In a yard with different tree species, there may be a range of trimming needs. A certified arborist can assess each individual tree to make the best recommendations for trimming, taking into account species, environment, disease or pest activity, and the tree’s natural life cycle. Improper trimming at the wrong time of year can cause a tree’s health to decline substantially. A certified arborist’s knowledge of tree biology and trimming best practices leads to the best trimming recommendations for your trees.

Is there a best time to trim a particular species of tree?

While it is generally best for all trees to be trimmed in the fall and winter, it is important to be aware of issues particular to a given species.

Oaks:

• The best time to trim oak trees in Texas is in the fall and winter.
  • It is critical to avoid trimming during oak wilt season (February-July) if at all possible.
  • Live oaks typically do a leaf exchange in late winter so it is better to trim them in late fall or early winter.
• Dead and broken branches can be removed at any time.

Maples:

• The best time to trim maples is fall and winter.
  • Pruning in the early spring can lead to sap leaking from the pruning cuts.
  • Maple trees are one of the few trees that have fall color in Texas so pruning after the leaf drop is usually preferred.

Elms:

• Elms are hardy and native to Texas. They are typically the first to get their leaves and the first to lose their leaves.
  Trimming elms in the fall and in the winter is best to avoid sap leaking.
• Elms are prone to rotting where large pruning cuts are made or poor puts are made so conservative trimming is best.
• In the parts of North America where Dutch elm disease is present, elms should be trimmed before March.

Crape Myrtles:

• Crepe Myrtles produce flowers on each year’s new growth.
  • Trimming in the fall leads to more blossoms in the spring.
  • Trimming in the late spring will reduce the number of flowers the following year.
• For the health of the crape myrtle, the best time to trim is winter.
  • Topping crape myrtles is never a good practice.

Bradford Pears:

• Bradford pears can be safely trimmed at any time.
• Proper structural pruning when needed is very important for Bradford pears because their natural growth patterns often lead to weakness at branch joints.

Fruit Trees:

• Structural pruning for fruit trees should be done in the winter.
• Trimming for fruit production should be done just after bloom in early spring.

At Texas Tree Surgeons, we love trees and we love our customers. In the winter, it can be easy to forget about our trees, as their leaves are gone and we spend less time outside. However, remembering that winter is the best time to trim trees can lead to healthier, more beautiful trees in the summer. We are always happy to come out and assess your trees for their particular trimming needs. When tree trimming must be done out of season, we are able to make sure that best practices are followed to minimize any negative effects. One of our certified arborists can make personalized recommendations based on your trees. Get in touch today!

With all the storms in 2019, we have seen unprecedented damage to our community. We have previously covered what happens when a tree falls on your house, and we wanted to supplement that information. We reached out to Katie Tu, a content specialist with QuoteWizard, to answer a few questions.

Does home insurance or auto insurance cover a tree falling on your car?

Most people think that their homeowners insurance will cover the costs if a tree falls on their car. However, this is not the case, unless your car happens to be parked in your garage and a tree falls through the garage and damages your car. In most other situations, your auto insurance will be the one you should look to for coverage.

Keep in mind that different insurance companies will handle these types of situations differently than others, and if you have any specific questions, you should contact your agent for clarifications.

What part of my auto insurance covers for tree damage?

Auto insurance comprises of the following elements: liability, collision, comprehensive, personal injury protection (PIP), uninsured motorist, and underinsured motorist. 

In the situation where a tree damages your vehicle, your comprehensive coverage is where you will be covered for it. Comprehensive coverage protects you from things like theft, fire, falling objects (like a tree), and natural disasters. 

Depending on your state or auto lender, you may not be required to have comprehensive coverage. However, if your car does get damaged for some of the reasons mentioned above, it’s a good idea to consider having it.

Are there any limitations to the coverage for tree damages?

That is going to be dependent on your insurance carrier and the coverages they offer. However, we do know that there are a couple things they may not cover:

• Your carrier is unlikely to cover repairs that cost more than the worth of your car. Therefore, if your vehicle is totaled, they are likely to pay the actual cash value of the car instead.
• They may not pay for the removal of the tree. You may think this is something you could do, but you may risk damaging the car even further. We suggest calling professionals to assist you with removing the tree.

What are the next steps after a tree has fallen on my car?

As soon as you notice the damage to your car, contact your agent or a representative of your auto insurance company. Try to provide as much detail and information as you can about what happened, and they can help navigate you on the next steps.

After completing your conversation, here’s what you should do:

• Take lots of photos: Try to get different angles, close-ups, and whole picture.
• Remove the debris: Avoid hurting yourself or doing any more additional damage. If the job is too big or dangerous for you to do yourself, consult with a tree care company for assistance.
• Check your policy: If you didn’t do it over the phone already, check your policy limits and your deductible. You’ll want to make sure you’re also able to pay for your deductible as well.
• See where the tree damage came from: Check to see if it came from your neighbor’s yard or vice versa.

If the tree that fell on my car was my neighbors, whose insurance pays for it?

If you suspect that your neighbor is at fault for the tree damage to your car, their insurer could pay for the damages if you have hard evidence or proof that they were negligent with care. Evidence like a dated letter to your neighbor asking them to cut the tree due to rot or some other reason could help with your case.

Keep in mind that this works both ways, so if you have a tree that could potentially cause damage to your neighbor, you’ll want to make sure you keep maintenance on it. If you ignore certain warning signs, you and your insurance may have to pay for the damages. 

Regardless, if a tree has fallen on your car and you’re looking for coverage, you would need to file a claim with your insurance.

How could I prevent this from happening?

Of course, to prevent any issues in the first place is to be proactive and do maintenance as needed for trees. If you have a tree in your yard, check it routinely, especially before hurricane season or the winter, to see if you may need to trim it.

It’s always a good idea to also check on your neighbor’s trees or talk to your neighbor about keeping their tree routinely checked to avoid any future damages or headaches.

At Texas Tree Surgeons, we love trees and we love our customers, and we hate to see destruction like we had in 2019. If you are concerned about the safety or stability of your or your neighbor’s trees, or have any other questions, let us know.
