Month: December 2022

Here at Red’s Tree Service of Memphis, we’re proud to be your locally owned and operated one-stop shop for all your tree-related needs. This includes keeping you informed about critical safety concerns, such as the signs of a dying tree. 

You may not realize it, but dead and dying trees can pose a severe safety hazard! In fact, research performed by the Occupational Safety and Health Administration (OSHA) demonstrates that dead and dying trees pose a greater risk to human health and safety than sharks! It turns out that every year, falling trees kill more than 100 Americans. Sharks? Less than 5. 

So how do I know if I’m dealing with a dead or dying tree? Well, that’s just what the subject of today’s reading is all about. So read on to learn the signs of a dying tree, and ensure that your family and property stay safe! 

Signs of a Dying Tree 

When it comes to identifying sick or dying trees, there are plenty of tell-tale signs if you know what to look for. For example: 

Sticks all over the ground 

A healthy tree has flexible twigs and branches that are less likely to break. It isn’t normal for a healthy tree to shed sticks at such a rate that you notice them all over the place! If your tree doesn’t exhibit signs of green wood in its branches, you can be sure something is wrong and should take action immediately. 

Bark Peeling 

Although different species of trees will exhibit varying degrees of peeling in bark, one sign that something is wrong is the excessive shedding of the outer protective layer of the tree. If you notice lots of peeling bark, then the tree isn’t getting enough nutrients. Similar to human skin, problems in the bark can indicate much bigger problems. 

 The Presence of Rot and Fungus 

Nothing is more of a surefire sign of a dying tree than considerable rot and fungus. There are numerous types of rot, all of which require intervention to save the tree in many cases. Different tree rot types include Brown Rot, the most severe form of tree rot, and causes the tree to dry up and literally crumble away. White Rot, while also very serious, causes the tree to feel excessively moist and spongy instead. 

Regarding fungal infections, Rhytisma acerinum and R. punctatum are the most common in the United States. Both appear most often in late spring and early summer, and both are characterized by black tar-like raised structures on the upper surface of leaves appearing alongside yellow spots.

Leaning 

A leaning tree will often have some underlying structural issue that indicates poor health. Unless you know this tree grew at an angle, you should take action immediately to avoid catastrophic damage from an imminent fall. 

Open Wounds 

While trees respond well to careful cutting and trimming, a large open wound in a tree, like that caused by excessive storm damage or lightning, can weaken and eventually kill the tree. 

That’s not all – Give us a Call! 

Thanks for taking the time to learn more about tree health and safety. The signs of a dying tree are numerous and should never be ignored, so if you have any questions or concerns, please give us a call.

Prevent your trees from rapid decline and death when wood-boring insects attack. Knowing how to control wood-boring insects will help you keep your Marietta, Georgia, trees healthy and thriving.

toddsmariettatreeservices.com gathered wood-boring insect species, identification, and control information to help you keep your Marietta, Georgia, trees safe.

Wood-Boring Insects

Wood-boring insects include a range of arthropods that cause damage to trees and wooden structures. This group of insects features an array of insect species at different life cycle stages (from larvae to adults). Wood-boring insects are seen as pests due to the potentially severe damage they cause in urban and rural areas.

Wood-Boring Insect Control

Systemic insecticides applied via trunk injection, bark sprays, or as a soil drench are effective against flathead borers and may be the only practical method for treating tall trees. Popular systemic insecticides include:

• Bonide Systemic Granules
• Mighty Mint Insect and Pest Control
• Natria Neem Oil Spray

Tip: Apply a systemic insecticide for trees when it is in the growing season.

Contact pesticides control wood-boring insects when they come in direct contact with the pest. Systemic insecticides are absorbed by and transported through plant tissue. Such products can render some or all of a plant toxic to insects that feed on it. Some common contact insecticides are:

• Pyrethroids (bifenthrin and permethrin)
• Chlorantraniliprole
• Imidacloprid
• Dinotefuran
• Emamectin benzoate
• Azadirachtin

Note: Each state has its own standards regarding pesticide use. Make sure you can legally use a pesticide before applying it to your tree(s).

Tip: Hire a professional tree service to treat your trees and alert regional representatives of any potential widespread infestations.

Wood-Boring Insect Species

Wood or tree borers could be bark beetles, twig pruners, or flat-headed borers, among other species. All boring insects are a hazard to a tree’s health, surrounding structures, and people. Consider the following species information:

1. Bark Beetles (Scolytinae)

Bark beetles tunnel under tree bark, cutting off its supply of food and water needed to survive. Bark beetles can kill a mature tree in two to four weeks during warmer months.

Identification – Bark beetle adults are tiny, cylindrical, hard-bodied insects about the size of a rice grain.
Tree Damage – Some trees slowly fade in color from green to brown, while others may die within a few weeks of infestation (these trees may not show signs of chlorosis, fading, or decline for several months.
Control Method(s) – If trees are infested, prune and dispose of bark beetle-infested limbs. If the tree’s trunk is extensively infested, the entire tree should be removed.

Note: The only effective treatment for bark beetles is preventative.

Vulnerable Tree Species: Bark beetles are attracted to tree species that are stressed, diseased, or injured.

2. Twig and Branch Pruners (Elaphidionoides and Agrilus species)

This insect is considered a secondary invader of trees in decline. The twig pruner attacks healthy twigs and small branches (the female lays an egg in the bark, and when the eggs hatch, the legless grubs bore into the twig). Mature larvae chew concentric cuts outward in the white wood without chewing through the bark. The infested branch eventually drops to the ground with the larva inside.

Identification – The twig pruner is a slender grayish-yellow, long-horned beetle about ½ inch long.
Tree Damage – Twig and branch pruner larvae feed beneath the bark, girdling twigs and branches.
Control Method(s) – Pick up and destroy any detached twigs. The insect’s life cycle is completed inside these fallen twigs. Eliminating the litter interrupts the twig pruner’s life cycle, so they never have a chance to mature and reproduce.

Vulnerable Tree Species:

• Hickory (Carya)
• Maple (Acer)
• Oak (Quercus)
• Pecan (Carya illinoinensis)
• Redbud (Cercis canadensis)
• Elm (Ulmus)

3. Bronze Birch Borer (Agrilus anxius)

The bronze birch borer is found throughout birch ranges in the US and Canada. It attacks and breeds in birch trees but has been spotted in beech and aspen stands.

Identification – Bronze birch borers are ¼ to ½ inch long, slender, dark iridescent, and bronze colored.
Tree Damage – Signs of this insect include off-color and thinning foliage in a birch’s upper canopy, dead branches in the upper crown, and swollen ridges on the tree’s trunk and branches.
Control Method(s) – Between May and June, you can spray infested trees with horticultural oil, permethrin, or bendiocarb to kill hatching larvae and adults emerging from the bark and feeding on leaves.

Vulnerable Tree Species:

• Paper birch
• Yellow birch
• Gray birch
• Western birch
• Water birch
• Sweet birch

4. Emerald Ash Borer (Agrilus planipennis) (EAB)

The emerald ash borer (Agrilus planipennis or EAB) is an invasive wood-boring beetle. Despite their color and appearance, these beetles are difficult to spot in the wild!

Identification – Adult EABs are bright, metallic green, with red metallic abdominal segments beneath their wing covers. This beetle is about ½ inch long and 1/8 inch wide with a flattened back.
Tree Damage – Larvae feed on the inner bark of ash trees from early summer to mid-fall, causing hydraulic failure and death. Infested native ash trees are all susceptible to attack.
Control Method(s) – When caught in an infestation’s early stages, emerald ash borer can be controlled by using systemic insecticides that are taken into the tree and move to areas where they can kill adults (leaves) or the flathead borer larvae (cambium).

Vulnerable Tree Species: In North America, all ash tree species can be attacked by EAB.

5. Carpenter Ants (Camponotus)

Carpenter ants get their common name because they excavate decayed wood to build their nests. Their excavation results in smooth tunnels inside wood. Similar to termites, this excavation activity can severely compromise a tree’s structural soundness.

Identification – Carpenter ants are about a half-inch long and completely black with yellowish hairs on the abdomen.
Tree Damage – This species does not eat wood; they only tunnel and chew through it to create nests. Typically, these ants burrow into trees already compromised by disease, softening their hardwood and facilitating the insect infestation.
Control Method(s) – A soap and water mixture is toxic to carpenter ants. Mix one part dish soap with two parts water in a spray bottle. Spray this mixture on the ants and around their nesting site as needed to kill them and eliminate their pheromone trails. Continue treating problem areas until the ants no longer return.

Vulnerable Tree Species: Any tree species compromised by a fungal infection.

Tip: Some insects are affected and can be contained without toxic checmicals, so read the following to learn how to make homeade bug spray.

Keep treatable diseases from infecting and killing your pine trees. Recognizing the signs of disease and taking action to stop them will help you keep your pine trees robust and stable.

72tree.com gathered the following information and tips about pine tree disease signs, treatments, and prevention.

Pine Tree Disease

In years with heavy rainfall or severe drought, pine trees may brown in response. Browning is typically caused by the pine tree’s inability to uptake sufficient water to keep its needles fresh and alive. When moisture is overly abundant (and drainage is poor), root rot and other diseases are often the culprits. Consider the following pine tree diseases:

1. Annosus Root Disease (Heterobasidion annosum)

Heterobasidion annosum is a basidiomycete fungus in the Bondarzewiaceae family. It is considered one of the most economically damaging forest pathogens in the Northern Hemisphere. Heterobasidion annosum is widespread in US forests and is responsible for $1 billion in annual pine tree losses.

Appearance – In some cases, resin flow may appear near the root collar as the tree attempts to defend itself against attack. Diseased pines may show crown thinning and yellowing. In pine trees, the disease is most active in the sapwood, killing tissues and heartwood as it progresses.
Treatment – Carefully remove and destroy infected trees and stumps. Any stumps left in the ground should be treated with borax.
Prevention – This disease typically enters a pine tree stand when spores land on freshly cut limbs or stump surfaces. The fungus grows from the stump into nearby live trees via root grafts or contacts. For prevention, treat stumps with borax whenever thinning in a high-hazard area.

2. Diplodia Tip Blight (Sphaeropsis sapinea)

Diplodia blight, previously called Sphaeropsis tip blight, is a common fungal disease of stressed conifers, most typically pines with needles in bunches of 2’s and 3’s.

Appearance – Needles of new shoots will remain stunted, turn straw-colored, and will be glued in place from excess resin. Mature needles on branches end up killed by girdling cankers. Sticky, clear-to-white resin is found on dead twigs, the main stem, or branches with cankers.
Treatment – If you previously had problems with Diplodia, consider applying fungicides as the candles are expanding and then two more applications at 2-week intervals (bud break, half candle, and full candle). This typically prevents any spores from being disseminated from infecting the tree’s succulent new growth.
Prevention – Proper tree care, including increased irrigation during drought, pruning, and equipment sanitation are often effective methods for control of Diplodia tip blight and canker, especially when pines are newly infected.

3. Dothistroma Needle Blight (Dothistroma septosporum)

Pine trees of all ages can become infected. Symptoms are typically first seen at the base of the crown on older needles. Infected needles develop yellow and tan spots and bands, which soon turn red. As the disease progresses, the ends of the needles turn reddish-brown while the needle base oddly remains green.

Appearance – Reddish brown spots or bands appear on needles in the fall. Needle spots girdle the pine’s needles. The needle beyond the band dies and turns brown, leaving the bottom portion of the needle green. Tiny black fungal fruiting bodies will appear in the bands or the needle’s dead areas.
Treatment – A copper fungicide spray is an effective method to prevent needle cast. Other useful fungicides are chlorothalonil and mancozeb.
Prevention – If your trees have a history of Dothistroma needle blight, copper fungicides can protect new needles from infection. Fungicides need to be applied before buds open in the spring.

4. Fusiform Rust (Cronartium quercuum)

Fusiform rust is caused by a curious fungus that produces five spore stages and requires an oak and a pine tree to complete its life cycle.

Appearance – Fusiform rust is caused by Cronartium quorum f. sp. fusiforme. It produces bright orange spores on southern yellow pines, especially loblolly pine, in springtime.
Treatment – Avoid planting any rust susceptible pine tree species in locations where fusiform rust is or has been an issue. Pruning branch cankers and completely removing diseased branches can help lower potential trunk infection. However, once the trunk is infected, branch pruning is no longer recommended (careful tree removal and destruction is).
Prevention – Disease prevention is best accomplished by planting resistant pine species and treating all oak trees growing anywhere in the vicinity of your pine trees.

5. Needle Rust (Chrysomyxa ledicola Logerh)

Pine or spruce needle rust is easily identified by pale, white, or orange blisters appearing on infected needles (in summertime). White blisters will appear on the current year’s needle growth.

Appearance – Yellow-to-orange spots or bands appear on green needles in spring. In late spring to early summer, tiny, raised, white tubes form on needles breaking open to release powdery, orange spores. These infected needles can remain attached to the tree for several years.
Treatment – Needle rust is considered a minor stress on pine trees and typically requires no management efforts. However, when necessary, the most efficient rust disease control is to carefully prune and destroy affected areas and remove any visible galls (abnormal growths) in late winter or early spring before they can produce spores.
Prevention – Follow these best practices to help prevent spruce needle rust:

• Redirect lawn sprinklers away from pine branches and needles.
• Plant your spruce trees far enough apart to allow good air circulation between them.
• Prune out and destroy wilted or blighted stems and branches.

Note: In most cases, pine needle rust is a cosmetic issue, and no management is needed.
