How Do You Save An Infected Tree?

Trees are silent sentinels that maintain the delicate balance of our ecosystem in the complex web of life that spans our world. These towering giants give us more than cool shade on hot days and firewood for our fireplaces. They filter the air we breathe, provide habitat for numerous animals, and moderate the weather that determines our everyday lives, making them the world's lungs.

In this blog, we'll travel to the forest's core to learn more about trees' role in our natural environment. Unravelling the complex web of life they support will force us to face an unpleasant truth: the ever-present danger of tree diseases. As we explore deeper into this issue, we'll see how trees play an essential part in maintaining ecological balance and how the destruction caused by infections can upset that balance.

Explore the world of these majestic trees with us as we learn about their importance as nature's architects and the need to safeguard them from the sneaky threat of tree illnesses. Let’s know how to figure out how to protect these unseen sentinels so that future generations might enjoy a cleaner, greener world.

Why Do Trees Get Stressed?

• Several external causes might put a tree under stress.  Drought, overpopulation, and stem/root damage are the most prevalent reasons. 
• Stem damage opens up entryways for bacteria, increasing the likelihood of infection. 
• Pathogens are more likely to infect a stressed tree, and roots that have been damaged open entrance points and limit the tree's ability to gather water. 
• Lack of moisture, crowding, or root damage contributes to a tree's diminished capacity to contain infections and keep them from spreading. 
• Good tree care lessens the effects of drought stress and mechanical damage, reducing the risk of tree diseases.

Signs of Pests and Diseases Commonly Affecting Trees

Leaf Spot

Fungal diseases such as leaf spots are expected in late spring and early summer when the weather is humid, warm, and wet. Leaf spot is host-specific and manifests as spots of varying sizes, shapes, and colours on the leaves of trees and gradual defoliation. Even though leaf spot might cause short-term damage to your tree by preventing photosynthesis from occurring, it usually isn't a significant cause for concern. Even so, you may aid in disease prevention and control by avoiding overhead watering, collecting and properly disposing of sick leaves in the fall, and thinning your tree canopy.

Its Effects

Leaves infected with a disease get spotted, become yellow or brown, and fall off the tree.

Control Strategies

Remove contaminated leaves by shaking the tree onto a tarp or other disposable surface, then dispose of it. Mulch heavily to keep the fungi from rising to the surface and prune the tree to improve airflow.

Powdery Mildew

Powdery mildew is one of the most widespread plant diseases. This illness manifests itself in the form of white spots or patches that resemble talcum powder. In warm, dry conditions, powdery mildews thrive because succulent tissue is easily broken down. Powdery mildew is disease-resistant to many plants but can still be effectively controlled with chemical treatments. Fungi from the genus Microsphaea are the most common cause of powdery mildew in trees. During the winter, the fungus survives on the leaves before being carried to the host plants by insects, wind, or rain in the spring.

Its Effects

A common symptom of this disease is the appearance of a powdery, greyish-white substance on the leaves. The leaves may warp. The colour of infected leaves can change from green to yellow or even crimson, and they may fall off. By late autumn, the white areas have tiny black specks dotting them like pepper.

Control Strategies

Select resistant species when planting trees and plants. Crape myrtles, crabapples, and lilacs are all susceptible plants, although there are cultivars that have been bred to be resistant to powdery mildew. Several fungicides can be used to get rid of this mildew.

Fire Blight

Fire blight is well called since it causes trees and shrubs to look as if they've been burned at the branch level. Some twigs' flowers and leaves wither and suddenly become brown or black. The bacteria that cause fire blight in trees thrive in humid, warm climates. The illness is spread by bees, rain, and contaminated pruning instruments.

Its Effects

The ends of diseased branches may droop. The bark at the twig's base first looks wet, then dark, depressed, and dry as the disease progresses. Fire blight kills off small groups of twigs at a time, creating a flag pattern over the plant.

Control Strategies

Cut off and dispose of branches that have discoloured more than 12 inches from the main trunk. After each cut, disinfect the pruners by soaking them in a one-part chlorine bleach solution with nine parts water. The spring and early summer are not the times to go wild with nitrogen fertiliser. It promotes the growth of succulents, which are more prone to infection by fire blight.

Leaf Rust

If you notice areas of orange, gold, or red bursting out on the surfaces of your leaves, you're dealing with leaf rust. Rust fungus seldom kills plants but can severely damage foliage and stunt growth by preventing photosynthesis. Each rust-vulnerable plant species has its rust species, which might seem very different from one another.

Its Effects

Leaves that are discoloured or mottled yellow to brown and powdery fungal colonies on the leaves are symptoms of leaf rust tree disease. It's possible to remove the powder by scraping it. Twigs and leaves may wilt and fall off, and the leaves themselves may twist and distort.

Control Strategies

Rust fungi rarely cause damage to plants and rarely necessitate pesticide applications. Get rid of and dispose of leaves as soon as possible in the fall. Several fungicides are on the market that can prevent the spread of rust. For up-to-date advice, consult your neighbourhood pruning service.

Canker

Canker is a disease that affects trees and causes patches of death on their trunks and branches. Mechanical injury from a lawnmower, environmental stress from things like frost cracks and sunscald, and various fungi and bacteria are all potential causes of cankers.

Its Effects

Surface discoloration and enlargement of surrounding tissue are common symptoms of canker on young or smooth-barked trees. A canker can be as minor as a lesion on a branch or as significant as a dead section of the plant's trunk. Cankers are a severe threat to young trees. Although they seldom kill mature trees, they can cause significant growth abnormalities.

Control Strategies

When trees are under stress or harmed, fungi that cause cankers thrive. Prevention is the most potent weapon against canker. Protect trees against disease and illness. Protect young, thin-barked trees from sunscald and frost fractures by wrapping them in the winter. Trees need more watering during dry spells.

If a branch has an infectious canker, take it down six to twelve inches. The same goes for fading or dead branches. To slow the spread of disease, prune when conditions are least favourable. If the tree is beyond saving, call a tree service immediately to have it cut down to prevent any potential damage.

Ways for Dealing With An Infected Tree

When a tree has problems due to diseases, pests, or the aftereffects of a particularly harsh winter, its owners may question if the tree can be rescued. However, if the tree's trunk is severely damaged, it is best to have it removed. Age and the surrounding environment are just two of the numerous variables.

Tree owners typically aren't trained arborists. Thus, it can be challenging to determine whether or not a particular tree can be preserved. A tree's health is best assessed by a professional, just as you wouldn't try to diagnose a severe ailment alone. If a tree threatens people or property, it is usually cut down rather than saved. It's safer to remove a tree before a storm hits if there's any chance it won't make it.

Work With Qualified Arborists

If you are concerned that any of the trees on your property may be diseased, consulting with a Certified Arborist can help. It's also important to remember that trees don't live forever. They naturally decompose after a certain amount of time. As long as the dead tree is removed promptly, it poses no threat to your home or family.

Decay in trees can be hazardous, yet they can assess the situation for you. Certified arborists will provide you with a thorough and precise assessment and practical and manageable advice. They can advise where to grow replacement trees if you have to cut down the decaying tree. The best way to ensure your trees live a long and healthy life is to give them the attention they deserve.

For Uncovered Roots, Try a Hand Trim

Roots that are too visible are like open sores on the human body. This disease can start in the roots and eventually affect the entire plant. If you're not careful, this can have severe repercussions.

In any event, you might attempt to cut away protruding roots from your tree physically. Adding extra cuts with a lawnmower or other sharp blades can be problematic later.

Take your time, and don't rush through the cutting process; you could damage the tree even more. These reductions may require additional time and energy, but they are necessary to slow the progression of the disease.

Avoid Excessive Mulch Use

Mulch is an essential component of healthy, fertile soil because it helps to retain moisture, slows the spread of weeds, improves aesthetics, and boosts the soil's health and productivity. However, mulch can stunt tree development if misused.

If you want to apply mulch around your tree, allow the trunk to expand and contract. The tree's trunk won't rot away under the mulch if you do this, either.

Don’t Get Weed Fertiliser on the Trees!

Weeds are unsightly and threaten the health of trees and other desirable plants by competing for water and nutrients. That's why so many homeowners apply fertiliser and weed killer to their lawns: to keep the grass healthy and free of weeds.

These products help eradicate weeds and repair the harm they've caused. Atrazine is typically used as a weed fertiliser. Weeds can be eliminated efficiently with the use of this chemical.

It's not just trees that it can kill out, either. Therefore, avoid utilising them near trees. If you notice any weeds growing near your trees, take the time and effort to pull them out by hand.

Make Sure to Water Your Trees When Required

Trees don't always fare well when left to their own devices. How else would trees get the water they need to survive in a drought? Some might laugh at watering a tree, reasoning it would never reach the roots.

However, when water is scarce, the roots of trees move closer to the ground to drink up every drop. If you water your tree during a drought, it will survive.

Follow Good Pruning Techniques

Tree pruning is essential but can be challenging. To maintain their vitality, specific species may require individualised pruning strategies. This is because trees can be harmed by inappropriate or excessive trimming.

This is because trimming often results in scarring on trees, providing ideal conditions for disease development. Therefore, you must develop good pruning habits to avoid accidentally killing your trees.
