Tree Injection vs. Soil Drench: Which Plant Treatment Is Right for Idaho Homeowners?

Plant health care has its own language, and if you don’t speak it, don’t feel bad. It’s rarely a category on “Jeopardy.”

But if you’re in a conversation with a plant health care service professional because your emerald ash tree is under attack by borers, or aphids are eating your aspen, it helps to know the lingo.

Here’s an example: tree injection vs soil drench.

Both treatments are designed to control some of the most troublesome insect pests that damage Idaho landscape trees, including aphids, scale insects, and destructive borers.

Which is better: tree injection or soil drench? Here at Lawn Buddies, we prefer tree injections for Idaho Falls tree care.

Let’s learn more about tree pest treatment in Idaho, including:

First, What Is a Tree Injection Treatment?

Tree injections are like shots for your trees, delivering treatments such as nutrients or pesticides directly into the tree.

Injections are placed beneath the bark into your tree’s active vascular tissue, usually with small drilled holes.

Treatments are injected right into the tree trunk, then quickly taken up by the vascular system and distributed throughout the tree.

What Is a Soil Drench Treatment?

A soil drench involves mixing a liquid chemical or nutrient and pouring it directly onto the soil around the tree's base, where the roots naturally absorb it.

Which is Better: Tree Injection or Soil Drench?

Here at Lawn Buddies, we prefer tree injections for tree care in Idaho Falls.

Tree injection treatments work almost immediately because they go straight into the tree. There’s no chemical drift like there is with spray treatments, and no runoff as there can be with soil drench.

Soil drench treatments have a much slower absorption rate. It can take weeks or months to reach the leaves. It’s also heavily influenced by soil conditions and carries a slight risk of environmental runoff or affecting nearby plants.

Tree Injections for Tree and Shrub Insect Control

Tree injections work great for treating insect infestations in Idaho Falls, Rexburg and Pocatello, controlling borers, aphids, spider mites and scale.

Bugs love trees. They love your aspen and ash trees, your crabapple, pear and dogwood.

Some pesky pests head straight to the leaves and start munching. Others are even more destructive, tunneling in through your tree’s bark and cutting off your tree’s water flow.

If it’s healthy, your tree might be able to stand strong and recover from occasional insect attacks. But repeated infestations will weaken a tree and can even kill it.

Expert tree injection treatments are designed to stop a wide array of damaging insects, whether they feast on your tree’s leaves and branches or tunnel into their bark.

Here’s a look at the two main types of tree eaters that can damage your trees:

How Borers Attack Trees and How to Stop Them

Boring or tunneling insects like the emerald ash borer and bronze birch borer can cause extensive damage to trees, boring into the trunk, branches or roots.

If you don’t stop them, they can kill your trees.

Borers do double damage when they lay eggs. When the eggs hatch, the larvae burrow deeper into the wood, blocking the tree's water-conducting tissues.

This destruction could be happening without you even knowing it, but there are some tell-tale signs:

• Entry or exit holes in the bark

• Small mounds of sawdust at the base

• Wilted or dying sections of the tree’s crown

Pests that bore into trees are quickly neutralized by direct tree injection treatments. The chemicals zap them where they eat.

Next Up: How Suckers Damage Idaho Trees

Sucking insects like aphids and spider mites suck out the liquid from leaves and twigs. Often they excrete a sweet, sticky substance called honeydew, which can cause sooty mold to form on leaves.

Tree injection treatments target these insect pests, too, as the product moves to the leaves and twigs they attack.

How to know if suckers are on the prowl:

• Scaly formations on branches

• Dying leaves

• Sticky honeydew appearing near your tree

How Do Tree Injection Treatments in Idaho Falls Save Your Tree from Insects?

Tree injections control insect damage by injecting systemic insecticides directly into the tree's vascular system. As sap and water flow through your tree, the insecticide travels up to the branches, twigs and leaves.

As insects eat your tree, they ingest the poison. This type of treatment works especially well on borers, beetles, aphids, spider mites and scale.

Idaho Falls tree trunk injections work faster and are more effective than spray treatments or soil drenches, which can take weeks to take effect.

Frequently Asked Questions About Tree and Shrub Insect Control

Q: When should trees be injected instead of soil treated?

A: There are many situations where tree injections are the ideal treatment as part of your Idaho Falls tree care. Here are just a few:

• When you’re targeting boring insects that burrow into your tree. Fast-acting tree injections reach them quickly.

• When you’re treating near waterways. Injections eliminate the risk of chemical runoff or leaching into nearby lakes, ponds, and streams.

• When you’re dealing with difficult soil conditions. Injections work better than soil drench treatments when your tree’s roots can’t absorb chemicals because the soil is wet, sandy, compacted, or has a high pH level that binds up nutrients.

• When you’re in a hurry to help your pest-infested tree. Injected treatments provide immediate absorption compared to the waiting period a tree endures while roots slowly process soil drenches.

Q: Are tree injection treatments safe for people and pets?

A: They are. The chemicals used in this Idaho Falls tree care are contained inside the tree.

People and pets can walk or play in the yard immediately after the tree injection.

There’s reduced environmental impact, too. The treatment happens inside the tree, so it doesn’t affect beneficial insects, nearby plants or wildlife.

Rainy? Windy? No problem. Tree injection treatments in Rexburg and Pocatello can be performed on rainy or windy days.

Q: What pests are treated with tree injections?

A: A whole host of damaging Idaho bugs are effectively treated with tree injection treatments, including:

• Wood-boring insects like the emerald ash borer or the bronze birch borer

• Sap-sucking pests like aphids, mealybugs and scale

• Leaf-feeding bugs, including Japanese beetles, elm and viburnum leaf beetles and gypsy moths

• Other assorted insects, including leafhoppers, leafminers and mites

Q: How long do tree injections last?

A: Tree injections typically last between one and three years, depending on the chemical used, the target pest or disease, and the tree's health.

Because formulas are injected directly into the tree's vascular system, they offer longer-lasting protection than topical sprays or soil drenches.

Q: Are tree injection treatments helpful for plant health care other than treating pests?

A: Yes! Idaho maple trees often have “iron chlorosis,” a nutrient deficiency. They can’t absorb all the nutrients they need from the soil. It can affect aspens, too.

The soil here in Idaho Falls has a high pH level, and this alkaline soil locks up any iron, making it unavailable to your tree’s roots.

Trees with iron chlorosis have yellowing leaves that never quite get green. Tree injection treatments deliver micronutrients directly into the tree, quickly replenishing it.

Tree injection treatments can also be used to treat tree diseases. Here at Lawn Buddies, we often use tree injections to treat fire blight, a super-destructive bacterial disease that typically strikes apple and pear trees. It can kill a tree’s blossoms, fruit, shoots, twigs, branches and entire trees.
