Never discount the importance of unseen dangers when tending to tree diseases, tree fungal treatments, and the overall health of your trees and shrubs. It's possible that microscopic organisms like fungi, germs, and birds aren't as obvious to the naked eye. However, they still pose just as great a threat to your family and your home.
The tree's leaf, wood, trunk, or even other sections may become infected with the fungus. Keep an eye out for the telltale signs of the most prevalent tree diseases, and then either take precautions to halt them in their tracks or treat any illnesses that have already taken hold. The goal of our tree care and pest management services is to ensure the long-term health of your trees and bushes.
Homeowners' anxiety and confusion over their trees' conditions are common results of their attempts to determine what is wrong with them. Can you explain this? What caused this to occur? Are there any risks to the tree? In what ways can you be helped? If you have tree problems, it's best to call a local arborist who can assess the situation and recommend a course of action. You may do a few things to keep your tree healthy in the meanwhile. It's ideal to take preventative measures. Trees that are strong and healthy will usually be able to stave off disease on their own.
The Top Ten Tree Diseases (And What to Do About Them)
In order to preserve the value of a landscape, trees must be kept in good condition. 10 of the widespread tree diseases and their treatments are detailed below.
Anthracnose
Sycamore, ash, and oak trees are particularly susceptible to anthracnose, a disease that affects deciduous trees. Shrubs, even secluded ones, aren't immune. Leaf spots, stem spots, flower spots, and fruit spots are all disfiguring side effects.
Since anthracnose fungus require water to propagate and infect, this disease is more common in the spring when it is damp and cold. Anthracnose typically doesn't need treatment because it's more of an aesthetic problem than a major threat to tree health.
Pruning affected branches and twigs during the tree's dormant season and properly disposing of fallen leaves are two cultural practices that can help limit the spread of this disease. Your trees, if well cared for, will flourish and rapidly cover any empty spaces in your yard.
Apple Scab
Scab can also affect mountain ash and pears in addition to apple and crabapple trees. The disease is caused by a mold that spreads through the plant's leaves and fruit, rendering them unfit for human consumption. Spots on leaves start out olive green but eventually turn black. Brown, corky, and misshapen are the final results of infection in fruit.
If you want to grow apples, choose a variety that can withstand apple scab. To find apple cultivars well-suited to your area that are also resistant to scab, contact your county's cooperative extension service. In order to reduce the likelihood of apple scabs in subsequent years, it is recommended that you rake and dispose of leaves well before the onset of winter. Infected trees can't be treated with fungicides, but healthy trees can be protected from apple scabs. The importance of timing cannot be overstated.
Canker Diseases
Cytospora canker, which affects pines, poplars, spruces, and willows, is just one of many canker diseases that attack trees. Infected bark or sapwood leads to canker illnesses caused by fungi or bacteria. When a tree's vascular system becomes obstructed, it stops receiving the nutrients it needs to survive. This obstruction may result in the death of branches, depending on the location of the canker. Wrapped all around the trunk, it might kill the tree from the inside out.
Trees that are under stress due to their surroundings, animal browsing, mechanical harm, etc., are the most at risk. Preventative strategies include pruning infected limbs, using resistant tree varieties, planting in suitable locations, and protecting trees from the elements throughout the winter. Use a bleach solution of 10 percent to disinfect the pruning instruments in between each use.
Cedar-Apple Rust
Cedar-apple rust is indeed a fungus, and its life cycle necessitates two hosts: cedar (Juniperus spp. ), and apple as well as crab apple (Malus spp.). Hawthorn trees are susceptible to another rust fungus called cedar-hawthorn rust.
This fungus lives on the cedar for its first year. The spores infect a second host the following spring, typically within a few hundred feet but occasionally up to a mile away.
Stunted branches and foliage become covered in vivid yellow-orange spots, and the fruit develops large fruiting bodies due to the illness. Premature leaf and fruit drop is possible. Planting a resistant variety to cedar-apple rust is one kind of cultural management (check with your local cooperative extension for recommendations). If you want to prevent symptoms from appearing, spraying a fungicide in the spring is a good option. A number of submissions are required.
Diplodia Tip Blight
Many different kinds of trees are susceptible to blight, but stressed conifers, especially Austrian pine, are particularly vulnerable to this disease. Stunted new growth that quickly becomes yellow, brown, and dies.
In dry weather, trees are more susceptible to diplodia tips blight, therefore it's important to keep plants mulched and hydrated.
Cones and branch tips that have been infected should be cut off and thrown away, and pruning shears should be disinfected between cuts using rubbing alcohol or even a bleach solution of 10%. In the spring, fungicides are often administered three times: once when buds first open, once before when new growth (called candles) are halfway emerging, and once when they are fully formed.
Dothistroma Needle Blight
This disease causes the tips of pine needles to turn brown. The tip of the needle slowly becomes brown and drops off. Among pine species, Dothistroma needle blight is most common in Austrian pine & Ponderosa pine, and it can be lethal to both.
Mulching and watering trees only at their bases, rather than spraying the leaves, are also effective preventative methods. One other option is to employ a fungicide.
In terms of personal security, nothing beats the privacy afforded by evergreens. Get acquainted with some additional plants that share your talent.
Fire Blight
A tree infected with fire blight will have blackened, withering leaves and branches that seem like they've been burned. A plant infected with fire blight may show symptoms such as dead branches and leaves in different locations. At its most productive in warm, wet weather. You can stop the spread of fire blight by cutting out and burning any affected branches back to healthy wood. Use a bleach solution of 10 percent in between each cut you make with your pruning instruments. However, there are measures you may do to protect your fruit trees against fire blight.
Oak Wilt
The oak wilt fungus only affects oak trees. Species belonging to the red oak group (those with pointed leaf lobes) are killed off by it, whereas those belonging to the white oak family (those with rounded leaf lobes) are now more resistant.
The tree's leaves begin to wilt & turn brown from the top down. Infected oak trees can spread the disease to other trees in the area through their roots or by attracting sap-feeding beetles after they have been cut down. Oak trees, in particular, should not be pruned while they are actively growing.
Using a tree injury sealant after pruning an oak during the planting season will make its wound less appealing to insects. If you take care of your oak trees, you'll be rewarded with gorgeous foliage in the fall.
Powdery Mildew
The white powder that forms on infected plant parts makes powdery mildew easy to see. Early leaf drop occurs as leaves become misshapen, yellow, and wilt. This fungus-caused disease is most prevalent on plants under shady places, and it thrives when there is high humidity but no precipitation.
Crape myrtle & lilac are two examples of plants that are sensitive to this pest, so it's important to use alternative, resistant plant species while landscaping. Provide adequate ventilation for the plants that are already there. Fungicides are another option for protecting your plants against disease.
Phytophthora Root Rot
Root rot caused by the fungus Phytophthora is a problem for plants in areas with inadequate drainage. Leaves on the trees appear to be drooping and turning a pale greenish or yellow due to drought stress.
Root rot can't be cured, but it's possible to stop it from happening in the first place. Do not plant trees in low-lying regions or beneath gutters.
You could also plant trees and shrubs that thrive in moist environments, such as bald cypress, willow, sycamore, and black gum. You should never bury a tree deeper than it was at the nursery; instead, plant it at the same depth or slightly higher.
Frequently Asked Questions About Tree
Arborists charge higher mainly because of the complexity, unpredictability, and risky nature of the tree service. Their overhead costs are also high owing to the high insurance premiums they have to pay.
A level 5 arborist is an arborist who has attained the highest level of qualification and experience that is possibly attainable in the field. Their extensive training, unrivaled tree knowledge, and wealth of experience usually make them ideal consultants.
Trees cost what they cost because someone selected the trees and purchased the liners/rootstock. Purchased the land and cleared it, installed irrigation if needed. Correctively pruned the tree regularly to get a desirable shape. Constantly checked for pests and disease and took corrective measures if needed.
Higher prices for live trees, she said, are a result of long-term industry trends combined with short-term factors, including higher costs for fuel, trucking and labor and severe weather in some growing regions.
There are two primary types of professional arborists: Certified Arborists and Consulting Arborists. The tree care needs of most home owners are best met with a Certified Arborist, who either performs the work or directs a crew of technicians to do the work. Not every tree worker is a Certified Arborist.
Preventative Tree Care And Treatment
Experts in treating tree diseases and tree fungus, with a focus on speedy and thorough removal. We put a lot of resources on primary prevention, which has helped us avoid the occurrence of three diseases so far:
- In the spring and the fall, as part of our regular Tree Care Plan, we apply a deep root feeding of fertiliser to your trees. Because of this, trees are able to strengthen and better withstand any diseases that may threaten them.
- As the summer progresses, we spray your tree multiple times with an anti-fungal solution to eliminate any spores that may have landed there or any diseases that may have begun to emerge as a result. Therefore, fungi are unable to colonise your trees, greatly reducing their potential to disperse and wreak havoc in your garden.
- During the summer, we spray the trees with insecticides at regular intervals, and in the winter, we apply latent oil to keep insects from bay. We also make sure insects don't chew holes in the plants that could be used by fungi.
Our Arbor Care Program not only helps keep trees healthy, but also allows us to quickly and effectively treat any illnesses that have already taken hold. We have a wide variety of fungicides as well as other infection-killing chemicals on hand, and after a thorough inspection of your trees, we can tell you just what they need to get well.
Then, we use the products as often as necessary to eradicate the illness. We'll also let you know the best way to water & prune your trees, as well as how to get rid of any debris that could be smothering them or harbouring pests that could spread illness. Don't risk fungal and bacterial infections and other devastating plant diseases by not protecting your trees.
To Avoid Disease, Follow These Four Tree Care Tips
Agricultural activities in the Valley attract a wide variety of pests and illnesses, many of which can be fatal to trees. Protecting your trees from pests, animals, and disease is essential for their continued good health.
To protect your trees from illness, consider these four preventative measures:
The First Step Is To Repel Insects.
Insects were accustomed to life on and around plants long before humans built them a shelter. As a result, they won't mind hanging out in one of your trees.
Common household pests, such as ants on trees, are not a reason for alarm, however, as they do very little damage. It's preferable to focus on less common pests like whiteflies, aphids, and scales. Some of these insects (like the whitefly) can actually infect the tree while they feed on it.
If you see any of these pests in your trees, you can spray wash it with hydraulic fluid or use pesticides. There are some insects (like scales) that are large enough to see and pluck off by hand if you have gloves.
Always Be On The Lookout For Warning Indicators.
Some experts claim that it can take up to two years for trees to exhibit signs of drought damage; do you think it will take that long for them to become infected with disease? That's why it's crucial to keep an eye out for red flags. A sure sign of illness, for instance, is a reduction in the size of your tree's branches or leaves, or browning around the leaf veins.
Remove Dead Trees Right Away.
After realising that a tree on your property is dying, you must immediately get it removed. If one tree in your yard becomes diseased, it may transmit the disease to the others. The disease may have been present in the tree for some time, but you only noticed it now.
Every Tree In The Yard Should Be Treated.
As the old adage goes, "an ounce of prevention was better than cure," and in this case, treatment is the ounce of prevention. You can protect your tree from disease and insects with a variety of treatments. Using fungicide or other products to forestall the spread of fungi on the tree. This will prevent further fungal infections, which are among the most prevalent causes of tree disease (second only to pests, of course). Or, if pests are a concern, a pesticide can be applied to the tree to keep them at bay.
How Trees Defend Themselves Against Wounds, Illness, And Pests
It's strange that in the line of work tasked with helping to protect trees, yet in most cases actually saving trees from us. We do a lot of damage to plants by cutting them wit mowers and weed wackers, planting them too deep, and by mistreating them. If they could start fighting back like the mythical Fangorn Forest in Tolkein's The Hobbit, it would be scary. To give just one example, tree work would become significantly more hazardous.
However, trees have the ability to ward against pests and illnesses. They have both physical and behavioural safeguards that are analogous to our own immune systems. We know a lot more about how trees protect themselves than we did fifty years ago, and a lot of that is due to research conducted by the Forest Service.
It has been known for a long time that bark works as a barrier against tree diseases, much like human skin does to prevent harmful microorganisms from entering the body. Trees require stronger "skin" than we do since they cannot move away from potential dangers. Tree trunks, roots, and branches are shielded from damage, dehydration, and illness by many layers of both living and nonliving tissues.
What happens, though, when something breaks through this first layer of defence and tears through the bark is amazing. When a tree is hurt, it will use some of its sugar reserves to create protective compounds. The substance is subsequently deposited in a predetermined way inside the wound's perimeter.
Trees produce four distinct chemical walls in the formation of these CODIT compartments: two circular, one radial, and one relatively flat horizontal. This Forest Service paper is excellent if you're interested in the intricacies, although describing those walls is a bit obscure or boring.
It's important to note that the rate at which a wound heals (also known as "healing over") has little to do with how quickly it deteriorates.
How badly a tree rots relies on how well it can resist pathogens. If the tree is too feeble to protect itself chemically, then the closure is beneficial since the vascular system does not have to detour around the incision.
However, the effectiveness of this barrier varies greatly between different species. For example, the CODIT reaction to hard maple or white oak is quite high. When compared to species such red oak & soft maple, which generate chemical barriers adequately, poplar and willow rarely manage to produce any at all.
The health of the trees is also crucial. We all know that our susceptibility to illness increases dramatically if we are persistently stressed, hungry, dehydrated, or otherwise worn down. If a sugar maple's health is poor, it might not be capable of constructing sturdy chemical barriers.
Landscape trees are always more stressed than their forested relatives. A street tree has it even worse because of things like reflected heat, lack of room for its roots to spread out, road salt, air pollution, and more.
Moreover, the severity of the wound matters. A major wound can weaken the resistance even of a happy, healthy tree. Of course we all know that the tree eventually succumbs to deterioration.
Less is understood about how trees cope with insect pests. We know that trees fight themselves against insect pests by activating their internal colouring book to synthesise chemicals, which are commonly referred to by scientists as Bad Tasting Stuff (insects, that is – not scientists). It appears that trees may often adjust the concentration of their natural insecticide to target a certain pest. However, the damage that tent caterpillars & gypsy moths may cause shows that these customised chemicals aren't foolproof.
Conclusion
Pest management is important for the long-term health of your trees and plants. Recognize the most prevalent three diseases and take preventative or medical action. First, mould spreads swiftly through the plant's foliage and fruit. Apple scabs can't be treated with fungicides, but healthy trees may. Finally, a tree with fire blight has black, shrivelled leaves and burnt branches.
Dothistroma needle blight affects Austrian and Ponderosa pines. Mulching and watering tree bases are preventative practices. Tree injury sealers prevent insects from penetrating wounds after cutting oak trees during planting season. Root rot can be avoided but not removed by the Phytophthora fungus. We have fungicides and other infection-killing medications to keep your trees healthy.
Ants on trees are typical household pests but rarely cause major damage. Some tree-feeding insects, including whiteflies, can transfer disease. Infected trees in your yard might infect nearby trees. Fungi, one of the main causes of tree disease, can be treated. Trees have thicker "skin" than people since they are immobile. A wound's rate of "healing over" and deterioration are unrelated. A major wound might weaken a healthy tree.
