On your property, insects and microorganisms abound. If this is news to you, don’t go running for the sprays and bug bombs. This is a natural and beneficial state. Insects and microorganisms are essential components in plant-nutrient recycling and decomposition. This article covers how to help your trees resist pests with integrated pest management.

“A landscape without insects and microorganisms would be a very unhealthy environment,” notes Tchukki Andersen, BCMA, CTSP* and staff arborist for the Tree Care Industry Association. “The trick is to balance the threshold of healthy plants. Having too much of a good thing is when the naturally occurring insects and diseases become a problem. This is where integrated pest management (IPM) program may benefit your landscape plants.” Even if your goal is to have the best-looking yard on the block, it will look better if it is naturally healthy.

Periodic outbreaks of destructive tree pests and diseases occur as part of natural fluctuations in ecosystems. When homeowners take unguided actions against these pests, they often make these outbreaks worse. With guidance regarding the use and importance of IPM, a homeowner can lessen pests’ impact locally. IPM provides the steps needed to promote a healthy landscape, prevent destructive pest outbreaks, and ensure diversity and vigor on a property.

Begin by keeping your healthy trees healthy. Monitor for pests and use preventative and cultural controls. Controls include proper irrigation and mulch. Many qualified plant health care companies can assist you in this first step.

Increase Diversity

Many property owners have just a single tree or a few trees. Others have small backyard woods, which have become an important component of the urban environment. Small woodlands with a mix of tree species are often less

susceptible to pest outbreaks than woods with a single species.

A diversity of tree ages also reduces the risk of pest outbreaks. As with species diversity, age diversity increases the complexity and stability of the ecosystem. A natural balance of organisms is more likely to develop as age

diversity increases. For example, potential pests of young trees can be regulated by parasites and predators from well-established older trees.

“A healthy landscape is less susceptible to pest outbreaks and is more resilient if an outbreak does occur,” stresses Andersen. “When trees overcrowd the root zone, competition for light, water, and nutrients results in increased stress. Trees under stress are more likely to be attacked by pests.”

The first clues of a tree health problem may include yellowing needles or leaves, thinning foliage, or dieback on upper limbs. These problems may be caused by insect pests or disease pathogens. They may also arise from the “abiotic” factor. Abiotic factors include lawn maintenance activities, construction damage, drought, compacted soil, or fertilizer/pesticide misuse.

Avoiding Tree-Related Wildlife Problems: 3 Ways to Prevent Homeowner Headaches https://treecaretips.org/avoiding-tree-related-wildlife-problems-3-ways-to-prevent-homeowner-headaches/diseases-pests/ https://treecaretips.org/avoiding-tree-related-wildlife-problems-3-ways-to-prevent-homeowner-headaches/diseases-pests/#respond Mon, 28 Dec 2020 20:51:29 +0000 https://treecaretips.org/?p=2213 Trees are obviously important to local wildlife, but many arborists and tree-care professionals fail to consider the way their services

Tree-related wildlife causing damage to tree.

Trees are obviously important to local wildlife, but many arborists and tree-care professionals fail to consider the way their services influence local birds, bugs, and other critters. This not only includes things like the way you decide to prune the trees on a given property, but also the species you recommend clients install.

In some cases, these influences are generally positive – helping wildlife is generally a good thing. But in other cases, supporting local animals can cause headaches for homeowners and property managers. So, consider some of the ways your work will affect local wildlife species and be sure that you aren’t causing problems for your clients down the road.

We’ll talk about three different ways you can help avoid creating these kinds of problems and address existing issues so that your clients can enjoy a harmonious relationship with the local fauna.

Use Discretion When Installing Nut- or Fruit-Bearing Trees

Many beloved tree species – including oaks, apples, and cherries, among others – make excellent additions to client properties. But when installed haphazardly or without forethought, they can cause more problems than they’re worth. Accordingly, you’ll want to be sure to consider the way these edible items will attract wildlife when making recommendations.

But that doesn’t mean these trees should be completely avoided – far from it.

For example, an old white oak growing in the middle of a wide-open lawn may very well attract some squirrels and jays. But because it is growing away from fence lines, bushes, and other sources of cover, the aesthetic and monetary value of the tree may far outweigh the problems caused by a few bushy-tailed rodents.

Conversely, a row of young northern red oaks growing alongside a client’s driveway may cause huge problems. As the trees approach maturity, they’ll begin showering the area with acorns. This will not only attract rodents (and represent potential trip hazards for humans), but the nooks and crannies along the driveway will likely provide cover and shelter for the rodents too.

Allow this to persist for a few years, and your clients will likely need the services of an exterminator. And the exterminator will likely tell them that the trees – which you may have installed – will need to go.

What’s the best way to avoid tree-related issues? Learn more in this blog.

Help Homeowners Keep Tree Limbs Away from Rooflines

Trees don’t only provide food and shelter for wild animals; they also provide travel routes. This is especially true for squirrels, chipmunks, rats, and other rodents, who’ll often use branches to move between trees and your client’s home.

So, if the trees in your client’s yard are providing the local wildlife with easy access to the roof and attic, serious problems are essentially guaranteed. This is particularly true if the offending trees are of the nut- or fruit-producing variety.

Fortunately, addressing this issue is relatively straightforward: Simply recommend that your clients allow you to prune these branches and establish a roughly 10-foot gap around the roofline. Just be sure to plan your pruning cuts carefully and perform them in a manner that won’t cause structural problems for the trees.

As a bonus, keeping tree limbs away from rooflines will also reduce some of the fire-safety concerns that are important in some areas.

Deal with Stumps in a Sensible Manner

Living trees serve as an important resource for wild animals and wildlife, but it is important to note that dead stumps can also be very important for small animals – particularly rodents, snakes and stinging insects. As a tree stump begins to decay and the soil around it begins to soften, animals will often begin making and inhabiting tunnels and burrows in the area. Over time, these stumps can transform into veritable ecosystems and represent a serious threat to the health and safety of your clients.

Unfortunately, there aren’t many hard-and-fast rules regarding the best way to remove stumps to prevent rats and other critters from moving in and setting up shop. You’ll often find that grinding the stump down as flush with the ground as possible is the best plan of action, but at other times, it may be wiser to dig up the bulk of the stump and roots and then pack the area with fill dirt. In other cases, chemically “dissolving” the stump may prove to be the wisest option.

Essentially, you’ll just have to rely on your experience and expertise to decide on a prudent plan.

Final Thoughts

Ultimately, your primary job as a tree-care professional is to maintain your clients’ trees. But, because they are important components of the local habitat, the trees you recommend, prune and service will affect the local critters. And the activities of these animals will in turn affect your clients.

So, be sure to think about how wildlife will interact with the trees on a given property and recommend services that’ll help your clients avoid wildlife-related problems. They’ll appreciate it, which will likely help convince them to retain your services far into the future.

Most insects and pests hide away for the winter months, but that doesn’t mean they’re gone. Hiding within trees is one of the most common survival tactics these pests have. They do this to survive, but they can also cause serious harm to your trees and plants if you allow them to nest unchallenged. Here are a few examples of the common pests your trees might face this winter.

Red Spider Mites

One insect you have to worry about in winter are red spider mites. They can attack all sorts of plants but they are generally associated with apple trees. These little pests are very active in the spring and fall. In winter, they hide near the tree trunks in little crevices where they can stay as warm as possible until the temperature returns to normal.

When it comes to these pests, you could have an infestation brewing without even knowing. They spin webbing like normal spiders on plants so take a close look if you’re seeing that sort of thing. They’re extremely small so they might only look like a small red dusting on a plant.

They repopulate very quickly which can make them difficult to get rid of in other seasons. In the winter, however, a pest specialist should have no trouble getting rid of them in the colder weather.

Codling Moth Grubs

Have you ever seen one of those pictures of a worm crawling around an apple? These moth grubs do the same thing. They like to be around fruit-bearing trees and even some that produce nuts. In winter, they’ll spend the colder months in the crevices of a tree waiting for spring.

They’ll reveal themselves in the spring right as the fruit is beginning to grow. It will usually take a professional to find them in the winter, however. You’ll want to communicate that to your pest specialist before flowers start to bloom.

Aphids

Aphids aren’t the most threatening-looking insects in the world. What’s scary about them, however, is their numbers. Over 4,000 species of aphids are known across the world and they can quickly overwhelm a plant and cause it to yellow or stop growing entirely. In fall, they lay eggs in trees that will remain dormant for the winter months.

How to Treat these Pests

Luckily, the winter’s a great time to treat for these sorts of pests; they next in the colder months and prepare to hit the ground running in the spring. Here’s a handy guide to keep your trees healthy:

Weed and Prune in the Fall – Keep things neat and tidy around your trees before the winter sets in. It’ll make it easier to spot nesting insects or other infestations beforehand.
Spray your trees with a Winter Wash – There are organic, oil-based washing sprays that you can apply to your tree without any fear for its safety. They won’t harm pets or children, either. You can also go with traditional insecticide, but some of them can potentially harm your trees as well.
Use Glue Bands – It’s exactly how it sounds: A band of glue around the trunk of a tree. It prevents insects from crawling up your trees to nest.
Call a Specialist – If you’re not the type to get your hands messy around bugs, feel free to skip to a specialist who’s experienced in this sort of work.

Plant health care, also called PHC, offers a total health approach to landscape and plant health. Your arborist will monitor your property, watching for potential or actual problems in your landscape that might be best avoided or dealt with by implementing a PHC treatment program.

Traditional landscape pest control programs rely on “cover sprays.” The pest-control sprays offered to the client are based on the company’s knowledge of common pest problems and control measures in the service area. The cover-spray type, method, and timing are pre-determined by the company. The homeowner may have the option to choose from several pest-control programs. Traditional pest control programs are not necessarily obsolete or “bad” for the environment and maybe the best option for clients who have overriding concerns about program costs or are only concerned about one specific pest problem.

In contrast, plant health care technicians consider the landscape when deciding how to best care for plants. PHC technicians manage plant problems through careful monitoring of the landscape environment. Chemical controls may be part of the treatment, but they are not necessarily used in every treatment. Because of this, every PHC program is customized to fit the client’s property and expectations.

The PHC technician maintains landscaped plants by:

  • evaluating the landscape’s environment
  • noting the causes of plant stress (stressors)
  • maintaining plant performance through proper cultural practices
  • investigating the landscape through monitoring
  • identifying and treating problems as they occur

The following are examples of some common problems:

  1. Improper matching of the plant’s requirements to the landscape site
  2. Improperly planted
  3. Subjected to improper maintenance practices
  4. A combination of improper plant siting (wrong plant/wrong site), improper planting and improper maintenance techniques can cause plant stress and decline.

Your expectations

A PHC technician also will consider your expectations when deciding how to implement a PHC treatment program. One important question is, when do you, the client, want to resort to chemical control of pest problems? Some clients will tolerate a greater percentage of plant damage before requiring action. Other clients will tolerate very little plant damage. Often a client will tolerate less damage on a prized ornamental specimen tree located in the front yard as opposed to a group of shade trees growing in the backyard. This requires the PHC technician to apply a higher action threshold to some trees and/or sections of the landscape than others. Here, communication and understanding between the client and plant health care technician are key.

A professional arborist can examine your trees to find the source of a problem and recommend what, if any, treatments are required, including thinning dense woods, planting new trees, correcting soil deficiencies, increasing water and nutrients, or managing pests.

The post Wasp Nest In Garden Trees: Everything You Need To Know appeared first on Tree Care Tips.

Knowing the ins and outs of the insects that can craft a home on your trees is an important part of maintaining the upkeep of healthy and functioning plant life. Wasps often live in your gardens and can be seen among the tree branches. Knowing more about a wasp’s behavior can help you keep safe in your garden. For any homeowner who owns a garden with trees, keeping on top of the ecosystem is vital. When a nest is spotted, people will rush to call for solutions.

Before you search to get this treated by a professional, read these facts.

Identify

So how do you know whether there is a wasp nest in your tree? Firstly, you need to know what you are looking for. Wasps can build their own structure or inhabit spaces such as hollowed trees or empty foxholes (to name a few locations).

Where there are no obvious structures that indicate a wasp nest in your garden, you can keep an eye out for consistent entry and exit points. Places in your tree where it seems as though wasps appear to be entering and exiting frequently. When wasps decide to pitch up their home on the branches of your tree, their nest will be easily distinguishable.

Mostly grey in color, they often look as though the grey paper has been stuck together. This then forms, what looks like, a small paper mache football. It is important that you catch the nest sooner rather than later. A nest can grow rapidly in size, over only a short period of time. So keep an eye out for these on the branches of your trees and watch a wasp’s flight patterns. This way you will identify when you may need to take action.

Dangers Of A Wasp Nest In Garden Trees

Wasps have accrued a rather fearsome reputation as one of the most aggressive and feared pests in the UK. There are people, such as those with allergies, children or the elderly, who are greater affected by a wasp sting. This is why, depending on how actively you use your garden, treating the nest is often the best solution. With greater activity in the garden, people come into contact with the tree that homes the wasp nest on a more frequent basis. And when a wasp becomes distressed, it is a bad sign.When aggravated, they emit a pheromone that signals nearby members of the colony. Wasps will then come flying from your tree to the defensive aid of their comrade.

If your trees bear any fruit, they are also at risk! Wasps will tend to burrow into the flesh of fruit such as pears and apples, to get to the sugary juices within. There is often little that you can do to combat this. Your only option is to pursue the removal of the entire nest from your garden tree.

Benefits Of A Wasp Nest In Your Garden Tree

For all the bad rep that these insects get, they do serve a purpose to the ecosystem in your garden. One of their primary food sources include caterpillars and other insects, which they feed to their grubs. A healthy population of wasps in your garden will help to keep the population of these pests from getting out of control. This will keep the leaves on your trees from being overrun and destroyed. Although this may not be a good enough reason to keep an active wasp nest in your tree, it at least gives you an understanding of their existence.

A small crumb of comfort to a recent sting victim, we know. Having said this, wasp nests in trees should only be removed if they pose a health and safety risk to the public. Which, in your garden, is often the case.

So, What Attracts A Wasp To Your Garden Tree In The First Place?

Besides the more obvious reasons such as easy access to set up a nest and easy food sources, there is another lesser-known reason. The reason you have a wasp nest on your garden tree often means you have an Aphid problem. Not a wasp problem.

What is an Aphid you may ask?

They are small insects that suck sap from the leaves of trees, particularly poplars, aspen trees, and evergreens. When they feed on the leaves they leave behind a sweet and sugary trail. This attracts the wasps to the tree and they begin to swarm towards it to feed on the honeydew. The Aphids are particularly fond of trees that have been weakened by under-watering, as the leaves are more rich in protein and a far more appealing meal. So, the best way to deter wasps from your trees is to treat the Aphids themselves. Therefore, a different treatment method will be needed.

Treatment For Your Trees

It is important to wait a short period of time before attempting to treat the nest. Nests can often move within the first 48 hours.  Regardless of the size of the wasp nest in your garden tree, when a Queen decides that they want to move the nest, the wasps listen. Usually, they will deem the environment to be unsatisfactory within the first 48 hours and move to a more suitable location. Where no nest is present, it indicates the wasps are swarming around your tree. Observation is needed, looking out for signs of a nest being built. But when you spot an obvious nest, establish that it has been active for some time, and deem it a health and safety risk, you need to act.

DIY solutions are never optimal. They put you at risk of aggravating the nest. Not to mention a few too many stings for anybody’s liking, also. Over-the-counter treatments are not as strong. They are not as effective as the chemicals that are used by trained pest controllers. It cannot be guaranteed that pesticide treatments will never cause any additional harm to non targeted insects, wildlife or plants. But treating with pesticides is not dangerous when controlled and undertaken by a professional.  The pesticides used are fast-acting, manufactured to eliminate the wasps and break down quickly. Pesticides are designed to cause as little effect to your trees as possible. Learn more about pesticides now!

To Conclude…

Hopefully, this article has shed some light on why, where and what wasps are doing in your trees. If you ever have any problems that you believe needs treating, remember to spot if there is a nest or entry point first.  Keep calm, stay clear, and if they do not move on, seek assistance to keep your mind at ease!

The post Smart Use of Fall Pesticides appeared first on Tree Care Tips.

As fall approaches, homeowners and green industry professionals take steps to prepare landscapes for the winter. Leaves are swept away for composting or disposal, perennials, and shrubs are pruned, hedges are trimmed and pesticides are applied in anticipation of next year’s growing season.

For professional arborists and landscapers, fall and early winter are an effective time to use pesticides, a broad term that includes products that kill insect pests and also kill weeds (herbicides).

Light Touch

“Many people might not have to use pesticides at all,” says Tchukki Andersen, CTSP, BCMA* and staff arborist for the Tree Care Industry Association (TCIA). “Professionals may be able to solve landscape problems without pesticides by choosing non-chemical alternatives, such as sanitation procedures and selecting shrubs and ornamental trees that are less susceptible to diseases and insects.

“For example, an infestation last year may only require all the old plant material be cut out,” notes Andersen. “Often, cultural practices (pruning, raking leaves, etc.) will go a long way toward solving pest problems.”

For homeowners who decide to use pesticides, TCIA offers these suggestions:

  • Identify the pest first. There is no use in applying a pesticide that won’t address your pest problem.
  • Don’t be tempted to use agricultural chemicals. Their design is not for use by homeowners. A small miscalculation in the mixing of a small batch could result in drastic overdosing.
  • Buy the least toxic product. Most chemicals available to homeowners use the signal words “caution,” “warning” or “danger” on their labels. Try to avoid those with the “warning” and “danger” labels, as they are more hazardous.
  • Never mix herbicides with other kinds of pesticides, and never use the same equipment to spray herbicides and other pesticides. You could unintentionally kill the plants you are trying to protect.
  • Don’t mix or store pesticides in food containers, and don’t measure pesticides with the measuring cups and spoons you use in the kitchen. Always store pesticides in the original container, with the label intact.

The best choice may be to consult a professional who can diagnose pest problems and recommend chemical or non-chemical alternatives. A beautiful lawn, shrub or tree isn’t worth the trade-off if pesticides are not being used properly.

Herbicides

Fall is a good time to inspect walkways, driveways, and patios for those annoying trapped seeds. Despite drought and frequent sweeping, some seeds from weeds, grasses, and trees will have germinated, lining joints with unsightly green. Other seeds simply lie in wait until the spring. This new growth must be stopped before the growing season arrives and those small cracks become gaping holes filled with vegetation. Herbicides are the most cost-effective way of eliminating unwanted weeds, but homeowners need to be careful when using herbicides! When they are used improperly, they can just as easily kill your valuable mature trees and shrubs as sprouting weeds. Users should read the product label to ensure proper application methods.

“Herbicides should not be applied on or near desirable trees,” cautions Andersen, “or on areas where their roots may extend or in locations where the herbicide may be washed or moved into contact with their roots. Even properly applied chemical applications may be affected by rainfall. Some herbicides can be washed off paved surfaces or soak into the ground through the cracked joints – the very place with the greatest concentration of fine tree roots.”

If you are thinking about using herbicides, hire a professional arborist. A professional arborist will choose the correct type of herbicide for the job.

Ah, summer! We’re certainly in the heat of it now!

It may be too soon to start thinking fall foliage, early changes in leaf-color in late summer can be a sign that your tree is under stress and vulnerable to insect and disease attack. If the leaves on your trees are changing color sooner than similar trees in the area, consult a professional arborist. They can help identify any problems and offer possible solutions.

“Premature color change can be an indication that a tree isn’t vigorous enough to withstand insects and disease organisms that may attack it, not to mention the usual changes that occur when the weather turns cold,” says Tchukki Andersen, BCMA, CTSP* and staff arborist with the Tree Care Industry Association. “Occasionally, only one or two limbs of the tree will show premature fall color. This could be a sign of a disease at work, though only the infected limbs are weakened.”

Next, a common situation is for the entire tree to exhibit premature fall coloration, a phenomenon usually linked to root-related stress. “Trees respond to these stresses by trying to restrict their above-ground growth, which affects leaf color and heath,” adds Andersen.  Root related stress can be caused by many things: extended drought or flooding, construction activities, fertilizer imbalances, and even improper planting.

What to Do

Correcting the symptoms of early leaf color changes – or even early leaf fall – might take a systematic approach to regain tree health. The first step is to get an accurate diagnosis of what stressors are affecting the tree. This is where your qualified tree care provider can offer some advice. Perhaps reversing the effects of tree stress is just as simple as changing the watering regime, fertilization application or even pruning out affected branches. If there is a treatment available, it could take a few growing seasons for the tree to come back into full health.

Most homeowners with landscaped yards enjoy the thought of an inviting outdoor space they can show off and enjoy. But creating a beautiful outdoor living space takes effort and patience.

“Attempting to force beauty onto trees and shrubs with bad pruning methods and overzealous spraying for pests is a haphazard approach that wastes time and money,” says Tchukki Andersen, BCMA, CTSP* and staff arborist for the Tree Care Industry Association (TCIA). “The result is usually only sickly plants to show for all that effort.”

“A plant health care (PHC) program is like health insurance for your trees and shrubs. It can take the struggle out of your landscape work and give you back the time you envisioned having to enjoy the results,” she says.

What is plant health care?

Plants, and trees especially, are valuable assets for your landscape. As such, they require long-term, quality care in order to provide return on your investment. A PHC program accomplishes this by using specialized monitoring and problem-solving methods designed to prevent high-cost plant/tree replacement in the long run.

How does PHC work?plant health care technician

The goal of PHC is to maintain tree and plant health in your yard by providing proper growing conditions for the plants. Most health problems associated with trees can be linked to past environmental stress or declining growing conditions. Healthy trees have natural defenses, but when a tree is stressed, it is more vulnerable to harmful insects and diseases.

“PHC technicians work closely with homeowners to reduce those tree stressors and manage pest problems before they become harmful,” says Andersen. “Managing plant pests and problems rather than eliminating them offers a proactive and holistic approach to maintaining tree and shrub health.”

Who can do this for me?

An arborist qualified to provide plant health care will make proactive visits to your property to inspect for signs of any plant health problems. Considering your landscape goals, the PHC technician will help guide your plant-health regime. Your expectations and concerns about your trees are vital to the success of the PHC program.

Managed landscape plants sometimes require specialized “treatments,” as many living things often do. In the past, landscape pest control treatments were primarily pesticide or fertilizer applications made regularly, regardless of need. PHC spray treatments are not necessarily obsolete or “bad” if performed by a qualified technician for a specific pest. In fact, some spray treatments may be the best option for clients who have cost concerns or are only concerned about one specific pest problem. Nowadays, though, good plant health care provides specific treatments at specific times, which better targets pests and reduces waste.

But the best treatment methods are those that work in combination with natural processes or are the least environmentally intrusive. A PHC technician may recommend any one or a combination of the following treatments:

  • Maintenance or restoration pruning
  • An integrated pest management (IPM) program to deal with any insect and disease issues
  • Mulching bare soil beneath tree canopies
  • Testing to determine any nutrient deficiencies/toxicities and a program to address them
  • Evaluation and correction of current irrigation practices
  • Planting pest-resistant varieties of trees and shrubs suited to your specific site

But can it help my trees?

Most people want to know what the pest problems or the overall problems are in their landscape. Your PHC provider observes your trees and shrubs for changes in their health and will work closely with you to devise solutions. A custom-designed PHC program for your trees and shrubs will, over time, provide a beautiful and healthy landscape that will add value to your home.

Have you ever heard of the children’s book, The Giving Tree by Shel Silverstein? It’s a story about a tree that gives a boy everything it has, such as apples, wood and shade, to make him happy throughout his life.

Every tree is a giving tree, isn’t it? Trees are wind obstructors, fresh air makers, pollutant reducers, shade producers, and block us from the cold. They entertain kids for hours with tree houses and swings. Trees let us relax with a hammock and a good book. One of the best parts about trees is they only require a little maintenance and care in return.

But what happens when your tree looks a little down in the dumps? An undiagnosed sick tree could kill your other surrounding trees, leaving your yard treeless. It could also fall, which can harm you and your property. Therefore, it is crucial to keep an eye on your tree to be aware of any symptoms that point to it being unhealthy. Here’s some information to help you know what to do when your tree is dying.

Symptoms of a Sick or Dying Tree

There are several common symptoms of sickness that you can watch out for to determine if your tree needs help. Then, it’s all a matter of diagnosing and taking action! A few common warning signs are listed below:

  • Poor structure
    Sometimes trees can lean more to one side, or have an odd shape that is caused by an unnatural growth pattern. Severe storms and poor pruning are usually to blame for this; rectify this issue soon to prevent the tree from falling!
  • Decay
    This one can be hard to spot, as decay usually affect the inside of the tree first. Visible symptoms include: mushroom-like spores, an expanded base, dead branches, and soft, breakable wood.
  • Weak unions or joints
    These are also an indicator that your tree is sickly. If your tree’s branches don’t look very attached to the tree, there is a problem. This is caused by branches growing close together with bark in between. Weak branches mean they could fall at any time.
  • Cracks
    Cracks in your tree are tricky to diagnose because some are normal and some are not. Overall, the cracks don’t necessarily hurt the tree unless they become too deep and affect the tree’s infrastructure and branches, or if they host detrimental pests.
  • Cankers
    Cankers are areas of dead bark on your tree. A canker is similar to a human canker sore; both are painful sores from a disease caused by stress. A tree canker is caused by bacteria/fungi that infect a tree through an open wound. Once it’s inside, it attacks the tree and causes it stress, and in turn, a canker. Fortunately, these can usually be pruned off the tree.
  • Deadwood
    The last symptom of a sick or dying tree is deadwood. Deadwood is exactly what it sounds like; wood that is dead. The branches are usually easy to break and are dry.

All of these symptoms are warnings that your tree’s health is threatened. The faster you identify these indications, the faster your tree can get back to normal.

Disease Prevention

So now that you’re familiar with some of the common illnesses and symptoms, what about actually saving the tree? Prevention is key.

There are certain things you can do to boost your tree’s health so it won’t get sick in the first place.

  • Avoid injuring your tree while doing any yard work. Wounds on trees are like open cuts to humans; they can easily catch an infection.
  • Watch out for any exposed roots, too, since root rot can be lethal.
  • Take care of your tree’s basic needs. If you have mulch around your tree, leave some room around it so it can breathe and absorb things.
  • Keep an eye on the weather. If you have been in a drought, your trees will need some watering.
  • Properly prune your tree. A pruned tree is a happy and healthy tree because it allows for proper growth and a strong immune system.

Arborists Are Your Friend

If prevention fails and your tree becomes sick, the best thing to do is to consult your local tree doctor, a.k.a., an arborist. They are certified experts that promote tree growth.

What an arborist can help you with:

  • Identify at-risk trees
  • Know the laws about chemicals and deforestation
  • Properly spray trees with chemicals
  • Alert you about any spreading diseases
  • Brace your trees for support
  • Recommend trees that would work well with your yard
  • Identify valuable trees you can sell
  • Give you pruning tips
  • Remove your tree
  • Climb up high
  • Use heavy equipment

An arborist will do all of the dangerous things for you to keep you and your home safe. So no rickety ladders for you! If there is any way to save your tree, an arborist will know and will be able to help. If you have any questions about your trees or see any of the symptoms listed above, give back to your tree and call an arborist in your neighborhood today.

The Massachusetts Department of Agricultural Resources (MDAR) announced today that a single dead specimen of the invasive pest known as spotted lanternfly (Lycorma delicatula) was discovered at a private residence in Boston, Massachusetts. As a result, MDAR urges residents to check for signs of this pest in potted plants received this holiday season. MDAR also asks residents to report any potential sightings of this pest on MDAR’s online reporting form by taking photographs and collecting a specimen if possible.

What is spotted lanternfly?

Spotted lanternfly is an invasive sap-feeding insect from Asia. It was first found in the United States in 2014 in Pennsylvania. The main host plant of this pest is tree-of-heaven (Ailanthus altissima). However, spotted lanternfly attacks a variety of trees, shrubs and vines.adult spotted lanternfly on tree

How did spotted lanternfly come to Massachusetts?

The insect appears to have been transported in a shipment of poinsettia plants from Pennsylvania. There is no evidence that this pest has become established in Massachusetts. Spotted lanternfly dies off when a hard frost hits. However, additional surveys will confirm no other lanternfly are present.

What should I look for?

Residents should look for large, gray insects, about one inch long, with black spots and red underwings.

“Early detection plays an important role in the protection of the economic and ecological resources of our state from invasive species,” said MDAR Commissioner John Lebeaux. “We ask all residents who have received potted plants this past December to help us protect Massachusetts’ environment and agricultural industries by checking for and reporting signs of spotted lanternfly.”

If you’re unsure of what to look for, a qualified arborist can help you identify this invasive pest and build a plan to treat for it.
