Benefits of Tree Inoculations or Trunk Injections


What are Inoculations Used For?

Just like humans, trees too require vaccines and immunizations to protect them from harmful diseases, insect infestations and fungal infections. The process of giving medicine to a tree for any reason, is called an inoculation or a trunk injection. There are really tons of problems that tree inoculations could be the solution for, however some of the most common reasons to inoculate or inject a tree include:

  • Dutch Elm Disease
  • Emerald Ash Borer
  • Pine Wilt
  • Oak Wilt
  • Pythium Diseases
  • Protection from Damaging Insects
  • Apple Scab

Why Trunk Injections Should Be Done By a Professional?

The first reason to have an arborist evaluate your tree and perform the trunk injection is because they are trained to diagnose tree problems and the identify the best possible treatment.  Some tree diseases and even insect infestations cannot be cured with an inoculation.  It’s important to have the proper diagnosis and treatment plan set fourth by a certified arborist.

Certain prescriptions can be harmful if mishandled.  Not only is the proper water to product ratio required, but gloves and protective goggles should be worn at all times.

The most effective area to inject the trunk is all the way at the bottom near the roots.  In some instances, an air spader should be used to uncover the portion of the flare found just below the dirt.  This is where the cambium layer can easily be reached, allowing quicker and more direct access to the vascular system of the tree.

An inoculation requires drilling holes about 1.25″ into the surface of a tree which leaves the tree exposed and vulnerable.  These holes should be done with great care, so that the tree can heal quickly once the medicine has been administered.  Creating holes that are too wide, too deep, or at the wrong angle could have harmful effects to a tree’s health.

Should I Have Tree Injections Done?

The answer is, have your tree evaluated by an arborist before committing to any treatment plan.  If and why you inject your tree depends greatly on your geographical location, the age and type of tree as well as what the known threats are at the time.  There are countless benefits to Inoculation Treatments, the biggest being that it is the quickest and most effective way of administering a prescription to a mature tree.  A mature and healthy tree has an immeasurable value to you and the environment.  The oxygen it transmits, the shade it provides and the beauty it lets off for years and years to come cannot be measured.  Our advice is to consider preventive treatments so you can enjoy your trees for years to come, and provide a safe and risk free environment for you and your family.

Summer Tree & Shrub Care Tips

The long hot days of summer may have you wanting to stay inside by the air conditioner, but these are the days when your trees need you the most. Increased hours of sun and summer rain team up for an immense time of growth for trees and shrubs in addition to a higher risk for insect infestation. Below are a few important preventative measures that will help ensure a successful summer season for your greens.

Pruning: Overgrown trees and shrubs are a big problem in summer heat because there is not enough fresh air circulating throughout the branches. A common misconception is that all pruning should happen during dormant periods, meaning the winter. This is false. Summer is a very beneficial time to prune trees, as it can be easier to identify weak branches when they slump from the weight of newly formed leaves. Also, summer is the ideal time to prune flowering trees and shrubs since they have not yet begun to form new buds. The general rule of thumb is to prune flowering trees and shrubs immediately after their blooms die. If you procrastinate, you run the risk of cutting off new buds which will mean fewer flowers for the following year.

Treat for Insects: Unfortunately, with warmer weather comes more pests, and we don’t just mean ticks and mosquitos, but the thousands of different bug varieties that can spread diseases to your beloved plants & trees. Most of the time, identifying an infestation requires a trained eye. Sometimes the bugs themselves are not visible so our Plant Health Care Technicians have to rely on symptoms such as leaf spotting, cracked bark or crown die-off. When it comes to insects, the best thing you can do is get in front of the risk with preventative care before a problem arises. At Emerald Tree and Shrub Care, we are extremely knowledgeable of all insect threats and can prescribe a treatment plan that will keep infestations at bay all summer long.

Provide Adequate Water: Just like humans, plants too require nourishment in the form of H2O during hot summer days. It’s important to make sure your plants and trees receive enough water, especially those that were planted in the last couple of years. An optimal amount of water for a tree or shrub is about 1-2 inches of water each week; just enough to reach all of the roots, both shallow and deep. Be careful not to overwater, as this could cause root rot, wilted leaves due to lack of oxygen or a condition called Edema when the plant cells fill with water and actually burst. Every plant and shrub is different, so it’s important to research the specific needs of your variety or consult with an arborist.

Storm damage prevention: Summer is the season for thunderstorms and heavy winds. To protect your property from falling tree limbs, consult with an arborist to assess the safety of your large trees. Cabling or bracing trees with weak limbs, or removing weak limbs completely, may be necessary.

Tick and Mosquito Control: What good is a backyard if you can’t enjoy it during the summer? To combat insect-borne diseases and viruses like Lyme, West Nile, Powassan and Zika in our own backyards, Emerald offers safe and effective mosquito and tick protection programs. Our treatments are organic and safe for your children and pets. In fact, you can go back to enjoying your outdoor space within 15 minutes of us spraying. For a free estimate complete this form.

Tree Health Diagnosis: Summer give us the best opportunity to identify tree health problems. Diagnosis of the actual cause of the tree malady is a tricky business best left to an expert. As with human illness, prompt detection and treatment can be critical. If you are unsure whether your tree is healthy or can withstand the next storm, consult our professional arborists who can identify and remove hazards as well as treat tree health problems.
