Trees that survived the severe storm damage are going to need special care over the next few years. The loss of canopy will reduce the trees’ ability to photosynthesize for food and to take up water. We are entering the hottest part of the year; after the rains have passed, increased watering and fertilization are key. It is up to tree owners to supplement the nutrients that trees need, but can no longer absorb from their environment. Your arborist can discuss fertilization options, including our comprehensive, year-round Plant Health Care programs. Contact us to make sure you are taking the best care of your damaged trees.

While fertilization goes a long way toward helping damaged trees recover, they are also more susceptible to disease and pest infestations. With the recent wet weather, fungal issues are increasingly common, but insect activity and environmental stress are also a danger. Over the coming months and years, we expect to see:

Tree Failure and Death in Some Cases

While trees have the ability to store energy to last them for years, as these stores are depleted due to damage and infestation, the trees will slowly die.

Oak Wilt

Already a major concern in North Texas, the oak wilt-carrying beetles are drawn to open wounds and damaged areas. Until we have temperatures consistently above 90 degrees, the beetles and the fungus they carry will remain active.

Sunburn and Sun Scald

With reduced leafy canopy, the branches and trunks of trees will be exposed to more direct sunlight, which can cause further damage. Red oaks are especially prone to sun-related damage.

More Broken Limbs and Tree Damage

Trees grow in response to their surrounding, especially other trees. When one tree in a group is damaged or removed, other trees are exposed to the environment in ways they have not been before. As future storms and wind move through the area, the newly-exposed trees may not be adapted to their exposed conditions, and may not be able to withstand the elements. Ask your arborist to see if tree cabling and bracing might be recommended to reinforce your trees.

As you are considering fertilization, also talk to your arborist about treatment for fungi, bacteria, and pests. While treatments have varying effectiveness, depending on the specific situation, your arborist can discuss options for your trees. Contact us to have an arborist come out for a post-storm assessment.

After such a loss, the best remedial measure is to plant new trees. The best time to plant trees is the winter, so use the intervening months to consider where and what kind of trees to plant. It may not be the best idea to replace a removed tree with the same species. Talk to your arborist about types of trees that would thrive in your particular conditions, and to discuss the best place in your yard to plant a tree. (Even if you have had a tree removed, we don’t recommend replanting in the same place, as underground root systems may hinder the new tree’s growth.) Choose native species that can better cope with our North Texas weather. If you don’t have room for more trees, consider supporting a community organization that is replanting for those who need them.

When the storm hit, one of our arborists was trapped in her home due to fallen branches, two staff members had flooded cars, two arborists were out of town, and our operations manager was stuck at a gas station, out of gas, waiting for the power to come back on. Our office was without power for three days, and those of us with power worked from home, the rest on the road, despite spotty cell service. Still, we tried to respond as quickly as we could, and have been able to assess over 700 properties for damage and deal with storm damage at nearly 200 homes. Visit our Facebook page for some photos of the damage we have seen!

At Texas Tree Surgeons, we love trees, and we hate to see such widespread damage. We are proud to call North Texas home, and we are grateful for the opportunity to care for your trees, and the continued support of our community. If you ever have any questions or concerns about your trees, please let us know!

If it’s time for a new look in your yard, or you recently lost some trees due to storms and are looking for replacements, our owner and ISA Board Certified Master Arborist Amy Langbein Heath has put together a list of her ten favorite ornamental trees for North Texas. Here is the second installment. If you have questions about what trees might be best for your specific landscape, let us know!

RedBud

When we say “redbud,” we usually mean the Eastern redbud (Cercis canadensis), but there are two other cultivars, Texas redbud and Mexican redbud, that are also common. All three varieties have heart-shaped leaves and pink/purple blossoms. The redbud is a relatively small tree. It has a short trunk, spreading branches and can grow to about 20 feet tall. It is often added to gardens and houses because it is one of the season’s earliest flowering trees and adds a lot of color with its burst of pinkish/purplish flowers. The redbud’s green leaves, stunning blossoms, and seed pods make it a beautiful decorative tree choice all year round. The redbud does best in full sun or light shade and the Mexican and Texas varieties are drought-tolerant.

Flowering Dogwood

Flowering dogwoods are a much-loved feature of gardens both in East Texas and the DFW Area. Dogwoods generally exhibit white blooms, but may also show pink or other colors. They bloom for 3-4 weeks in the springtime, and looks particularly spectacular during that time, but are a great decorative choice all year long. Fall brings crimson foliage, giving way to red berries in the winter. In their natural environment, dogwoods are understory trees, protected and surrounded by other trees. Because of this, flowering dogwoods prefer at least partial shade to thrive.

Yaupon Holly

Yaupon holly is a versatile, multi-trunk shrub or small tree. Yaupon can be trimmed into a hedge or left to grow as an individual tree, making it a popular choice for residential and commercial landscaping. A hardy evergreen, yaupons produce small white flowers in the spring and the female plants produce bright red berries that stay until fall. Yaupons are drought-tolerant and can reach a height of 25 or 30 feet. The dense foliage and berries are attractive to birds throughout the year. Additionally, the yaupon is the only caffeine-containing plant that is native to North America. The leaves can be dried and used for tea!

Japanese Maple

A graceful and elegant addition to the right landscape, the Japanese Maple is a local favorite for good reason. There are numerous varieties available, with foliage in a range of colors. Japanese maples start out with green leaves in the spring, which quickly mature into shades of red and ochre. These medium-sized ornamentals love the shade and thrive under larger plants or shaded by houses. One of the common issues we see with Japanese maples is too much sun, but if you have space in the shade, they can be a welcome addition.

Desert Willow

Looking for a low-maintenance, full sun, drought-tolerant tree? Meet the desert willow. The small tree or large shrub has a spreading crown with willow-like light green leaves. In the mid-summer, these have fragrant, pink flowers that form in clusters at the tip of the branches. This native tree can withstand the heat of our North Texas summers and its flowers are a great hummingbird and bee attractor!

At Texas Tree Surgeons, we love trees and we love our customers! While we don’t plant trees ourselves, we are always happy to give recommendations to help you find the perfect tree for your yard. Contact us online or give us a call and we’ll see what we can do to help!

At Texas Tree Surgeons, we love trees, but sometimes we need to remove them. This cottonwood had root rot and posed a danger to persons and property. The owner decided to take it down, and Texas Tree Surgeons was there to help. No problem.

If you have a tree that you are concerned about, or want to make sure that you are doing all you can to prevent hazardous situations, let us know, and we are happy to have one of our Tree Risk Assessment Qualified arborists out to take a look!

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!

Dear Texas Tree Surgeons,

A lot of my bushes, especially the red tip photinias, are starting to wilt and have reddish-brown spots on their leaves. What can I do about that?

Red Tip Photinias have long been a staple of North Texas flowerbeds and hedgerows. Hardy and fast-growing, the evergreen shrub can be trimmed to various heights and forms a good privacy barrier with its broad leaves. New growth has red leaves, giving the red tip photinia its name. Unfortunately, red tip photinias are particularly susceptible to leaf spot diseases.

This fungus Entomosporium mespili causes leaf spot on all members of the rose family, including red tip photinias. Starting as a red, brown, or black dot on leaves, the leaf spot expands outward as the fungus grows. Eventually, the red spots turn into a gray area rimmed by red. As the fungus spreads, it disrupts vascular function in the leaves, which eventually fall. The fallen leaves collect moisture at the base of the shrub, increasing fungal growth. As wet conditions continue, the fungus can spread its spores within water droplets, such as splashing from rain or irrigation. Left unaddressed, the fungus will spread throughout the photinias, causing wilting and dieback.

Environmental control

The first line of defense against fungal leaf spot, as with many fungal diseases, is to monitor watering and drainage. Fungi thrive in wet conditions of a moderate temperature, so the spring and fall are when we see the most activity. In periods of wet weather, the clay soil common to much of North Texas can hamper proper drainage, causing the area around the red tip photinias to become waterlogged. This moisture, mixed with the fallen and decaying organic material creates the ideal conditions for fungal growth. Even if the soil drainage cannot be improved, it is important to curtail watering so as not to make the situation worse.

In addition to moisture, the fallen photinia leaves contribute to the growth of the Entomosporium fungus. Keeping the area around the plants clear of debris can help slow fungal progression. In a similar way, dense foliar growth on the interior of the red tip photinias can collect moisture. Where possible, thin out dense areas to allow light and air to circulate. When trimming, make sure to remove any areas already showing leaf spot. Removed material, especially infected leaves, should be buried or disposed of in a plastic bag.

Chemical Control

Fungicides can be used to control Entomosporium leaf spot, but the process can be costly. Furthermore, treatment will be ultimately ineffective if the environmental factors are not eliminated. For valuable hedges, a continuous process of multiple-week treatments in the spring and fall may be recommended. In other situations, it can often be more cost-effective and better in the long-term to remove the affected plants and replace with a less-susceptible species. 

While there is no quick solution for red tip photinia leaf spot, we hope this information can help homeowners mitigate the damage to their shrubs, and decide if treatment or removal might be warranted. At Texas Tree Surgeons, we love trees (and shrubs! and hedges!) and we love our customers, and we always want to give our community the best, most accurate information regarding their plants. If you would like one of our arborists to come out and see how your photinias, or anything else, are doing, let us know!

When people talk about tree care, they can use different words to talk about the same thing. You may hear “trim,” “prune,” or “cut,” just as you may hear “limb” or “branch.” At Texas Tree Surgeons, we are often asked the difference between a branch and a limb, or between tree pruning and tree cutting. Unfortunately, there is no industry standard definition for many common terms, and that can cause confusion.

A NOTE

If you visit our Facebook page, you may notice that we are categorized as a “tree cutting” business. In other places, we may be listed as “landscaping services.” Unfortunately, because there is no universal standard term for what we do, we have to find the best fit under the circumstances. At Texas Tree Surgeons, we use the term “tree trimming” to refer to the work we do.

Proper Tree Trimming Is the Key to Healthy Trees

Trees are living organisms, and every cut that’s made on a tree has long-term effects. Additionally, every tree is unique and has different needs dictated by its environment and history. A heavy trim may have no adverse effects on a large, healthy tree, but a tree that is under pre-existing stress or has a potential for health issues might be irreparably damaged by removing too much canopy. Furthermore, safety and stability issues may restrict the amount and type of trimming that can be performed. It is important when trimming trees to take all of these factors into account, as well as to be mindful of the weather and seasons. Improperly trimming a tree at the wrong type of year can lead to severe decline and death. 

While there are no universal standards for tree trimming, there are two sets of guidelines for the tree service industry that we at Texas Tree Surgeons follow. The first is from the International Society of Arboriculture, or ISA. The ISA is the premier international credentialing and membership organization for the tree care industry. In addition to establishing the Certified Arborist and Board Certified Master Arborist credentials, the ISA provides a wealth of resources for tree owners. The ISA guide to tree trimming (they use the term “pruning”) covers the basics of how to properly maintain mature trees. In addition to the ISA, the Tree Care Industry Association (TCIA) oversees tree service providers in the United States. In collaboration with the American National Safety Institute (ANSI), the TCIA has developed comprehensive guidelines for tree care and management. These guidelines provide the basis for all of our work proposals and trimming. Adherence to these guidelines is the best way to care for trees of all kinds, and all our certified arborists are equipped to assess individual trees and determine the best — and healthiest — way to care for them. 

Trimming visible growth is only part of tree care. Without a proper understanding of what’s happening below the ground and underneath the bark, a beautiful trim is of little use. Certified Arborists are trained to spot the signs of environmental stressors, diseases, and insects. Poor drainage and soil condition, competition with turf grass, and proximity to structures can all affect a tree’s growth. Beyond just trimming a tree, certified arborists are able to evaluate the tree holistically in order to provide the best care possible. 

Whether It’s “Tree Trimming” or “Tree Cutting,” Cheaper Isn’t Always Better

Ultimately, what is important is the tree care itself, not what it is called. To give your trees the best chance to grow and thrive, look for tree trimming companies that employ certified arborists. If you have any doubts, ask for their certification number, or look for the arborist’s name on the ISA website. A properly-trained arborist should never recommend topping or lion-tailing, and should take proper precautions during oak wilt season (February-July). Never be afraid to get a second opinion. Give us a call anytime, and we are happy to have a certified arborist come out and discuss what work needs to be done and provide a free quote!
