Soil Injections: Everything You Need to Know About Removing Tree Pests

There are many purposes for soil injections from fertilizing your garden to stabilizing your property’s foundation. One of the most effective and necessary purposes for your tree’s health is pest control. 

Common Tree Pests

An invasive insect known as emerald ash borer (EAB) is known to attack Ash trees. This destructive species will hatch underneath the bark and feed on it, creating tunnels that disrupt the flow of nutrients in the tree. Providing the tree with the correct insecticides can prevent these insects from harming its system and allow it to thrive.

One tree pest that affects trees such as birch, aspen, and oak is the forest tent caterpillar, eating all leaves in mass outbreak groups. They cause trees to weaken with consistent defoliation and commonly kill trees by eating everything on them. According to the Forest Health Annual Reports, the next peak population in Minnesota may occur between 2024 and 2029, making it a perfect time to consider soil injections.

What Are Soil Injections?

Soil injections are designed to provide trees with systemic insecticides that allow them to fight off and repel infestations that may occur. This method begins with injecting the surrounding soil and root area with liquid chemicals until moist. The tree’s height and trunk size are taken into consideration when measuring the dosage, as to not shock the tree and cause further damage, leading to an expensive repair. The root system will then absorb the insecticide and distribute it to major feeding points such as leaves and bark. Once the chemicals are in its system, the pests will die after feeding on them. If done incorrectly, the tree may experience unnatural decay causing its health to significantly decline. 

Benefits of Soil Injections

Soil injections will provide long-lasting strength for your tree, eliminating the risk of infestations that would otherwise harm it. Injecting insecticides into the soil not only protects your tree from infestations, but surrounding areas from aphids that may be taking over your garden. Aphids are sugar-hungry insects that will cause your leaves to discolor and dry from consuming the nutrients from the root systems in your garden. Repelling these insects can be crucial for the survival of the ecosystem in your garden.

One complimentary benefit to this approach is limiting the use of chemicals in the affected area. Regular pesticides from a spray bottle can get blown into healthy plants that may become damaged. Furthermore, the spray can negatively impact beneficial insects that inhabit nearby plants or even the affected tree. Soil Injections combat this with a more targeted exposure, removing unhealthy insects in a specific spot.

However, insects aren’t always the problem. Like us, trees have immune systems that can become compromised from diseases. A common and often fatal disease is oak wilt, affecting all species of oak trees in Minnesota. It is caused by the fungus Bretziella fagacearum that grows on the sapwood layer of the tree, restricting water and nutrient flow. Oak wilt kills different oak species at different rates, being as fast as 2 months. The 2 approaches to saving a tree from oak wilt are soil injections or tree injections.  

There are alternative methods such as tree trunk injections, where a small hole is drilled into the trunk and the insecticides are applied directly. Soil injections eliminate some of the risks that come with open tree wounds in the trunks and root system

Best Practices to Prevent Infestations

Common causes of tree infestations stem from poor sanitation, lack of irrigation, improper pruning, and overfertilization. These create environments that are inviting for pests that can stress your tree, compromising its healthy system. Professional tree trimming is an effective way to avoid potential pests and limit the use of chemicals. Keeping your trees and shrubs evenly cut will deter pests that will otherwise defoliate them.

When Should You Consider Tree Removal

Trees can significantly enhance the look and appeal of your property and landscape. While they offer numerous benefits, there comes a time when their presence can become more of a burden than a blessing. Knowing when to remove a tree is crucial for gardening, property maintenance, and overall safety.

Storm Damage

Minnesota is known to get windy, and monitoring your trees' health can save you a lot of money and even lives. Trees often suffer damage during storms, with leaves and branches catching the breeze. Poorly maintained trees are prone to harmful twisting, leading to splits in branches and critical structural points. Observing these signs may tell you that it’s time for your tree to be removed before there is any further damage to the surrounding property or even other trees.

Leaning Trees

During these heavy winds, developing trees may be pushed, causing them to lean to one side and eventually onto another tree. This may also be caused by a lack of sunlight and long periods of heavy rain, which alters the direction your trees grow in. The weight of the trunk and branches will pull the tree to the side and slowly rip the roots out of the ground, compromising its structure. A visible root system is a probable sign to remove the tree. 

Dead Trees

A tree's structure can also be compromised if it's dead. This can sometimes go unnoticed without investigation. The easiest signs to spot are discolored, dry leaves or branches that fall off easily. Damage from decay or storms, such as cracked sections of branches or the trunk, poses a significant threat due to their unpredictability. 

Infestations

Diseases and insect infestations can accelerate a tree's decline, necessitating early removal. Emerald Ash Borer (EAB), a destructive species, significantly increases the need for professional tree removal. EAB damages the tissue beneath the bark, disrupting nutrient flow and slowly killing the tree. Visible cracks in the bark and feeding holes are clear signs of infestation. In late stages, when treatments won't save the tree, professional removal is essential.

5 Reasons to Regularly Trim Your Minnesota Trees

Tree trimming is often deprioritized, overlooked and seen as unimportant. Any local tree expert would know there are many benefits, hidden and seen, that can prove to be essential for your landscape health.

#1 Safety

Safety first! Trees will often decay in small amounts and as weather conditions change, so do the hazards. Untreated trees have an increasing risk of falling over due to uneven weight, rotten branches detaching easily, and diseases weakening the overall structure. 

According to The Department of Natural Resources, over 85% of all tornadoes in Minnesota occurred between May and August, making it a good time for tree trimming. Tree trimming removes the overgrown and unhealthy branches from your tree, which can pose a threat in windy conditions, resulting in damaged property as well as injury. This is the number one reason why it should not be overlooked and put off.

#2 Maintaining Tree Health

Dead branches are dead weight and can even cause other branches to deteriorate due to lack of nutrition. Smaller and younger trees will suffer from this more which may impede on their growth and decrease their chances of survival. Additionally, getting your tree professionally trimmed will detect all of the potential diseases, infestations, and rotted areas of your trees, limiting the damage they may cause in the future. 

A very common infestation that homeowners may not be aware of is Emerald Ash Borer (EAB) which may be weakening the stability of your environment. Within the 1st year of a tree's life, EABs land and lay up to 90 eggs on branches. By years 4-7, visible damage will appear including loss of branches. This is where our certified and experienced team of arborists come in and treat the tree so no further decay happens.

#3 Health of Landscape

Many plants need a consistent amount of sunlight that may be blocked because of shade cast by trees. Trees may also grow depending on where their sunlight comes from, causing them to lean more to one side if the other side is shady. Maintaining the shape and size of your trees will allow substantial sunlight and rainfall to pass through to other growths, allowing them to thrive in the ecosystem. 

If a tree is too thick and not well maintained, moisture will build up by its base and provide insufficient living conditions for plants below. It may also limit animal traffic through your garden, decreasing disturbances and other toxic elements that may stunt the growth of your plants.

#4 Visual Appeal

There’s no doubt that a nicely trimmed tree will provide your home or landscape with a better view and add a beautiful aesthetic. Showcasing the beauty of your Minnesota trees creates a peaceful and enjoyable environment you can only find locally. Regular tree trimming benefits include less maintenance for the next time around and keeping your garden looking more even and well-maintained. 

#5 Economical Benefits

Tree trimming might initially seem unnecessary, primarily for aesthetics. However, investing in regular maintenance can make a big difference in the future, saving you from easily avoidable expenses and increasing the value of your landscape. Reduce your landscaping costs by addressing problems such as common diseases in the early stages. In Minnesota, it is important to use professional tree trimming services to maintain the health of these beautiful native trees.

It may be intimidating to climb on a ladder and take on all your landscaping challenges by yourself. As if that wasn’t daunting enough, there are many ways you could go wrong in trying to prune your trees —such as cutting too much or exposing your tree to too much sunlight. That’s where we come in to help you achieve your tree care goals and enhance the value of your landscape.
