Welcome to Metamora, Michigan, where our trees are not just beautiful - they’re also under constant attack from a variety of sinister insect pests. We’re talking about bugs that sneak up on your trees when you least expect it, turning your lovely green giants into stressed-out shriveled messes. It’s basically Game of Thrones, but with aphids instead of dragons and emerald ash borers instead of direwolves. Fortunately, there’s hope! You see, the mighty weapon we’ve chosen in this epic battle is none other than a Soil Injection.

Now, let’s be real: protecting Metamora trees is a priority, but we don’t want to go around with a clipboard and spray bottle looking like a mad scientist, right? Enter the ISA Certified Arborist, your personal tree bodyguard. Our professionals will come to your property, assess the scene, and determine which plants should get the VIP treatment of a soil injection.

What is Soil Injection, you ask? Well, it’s a fancy way of saying "we inject the soil around the base of the tree trunk with a product that helps them fight off nasty insects without causing major chaos in the process." The active ingredient, usually imidacloprid, is like the secret superhero serum for trees. It gets into the tree’s vascular system and spreads through the canopy of tree. Only insects that feed on the tree are affected.

Timing is key, of course. We recommend scheduling the treatment during spring or fall - because trees are totally particular about when they want to be protected, naturally. Allow about four weeks for the product to be distributed throughout the tree’s system. Just think of it as a tree wellness retreat - imagine it sipping on a green juice while relaxing in the shade.

Soil injections environmental impact is minimal, plus, this treatment lasts for a whole growing season. Yes, that’s right, one application, and you’re covered for an entire season. You can relax, knowing your tree is immune to any unwanted insect guests for months, and we’re not talking about those nice ladybugs who just want to hang out.

The dosage is carefully calculated based on your tree’s size, which - here’s the fun part - depends on the tree’s trunk diameter at breast height (DBH). Yes, you read that right. We’re all about precision here. No half-measures. You want your tree to get the right amount of protection, and we won’t settle for anything less. Once administered, this magic juice stays within your tree for up to an entire year, which is why it’s so important to make soil injections a part of your annual tree maintenance routine.

Make an appointment with one of our ISA Certified Arborists today and let’s get those trees the protection they deserve because when it comes to insect warfare, we’re here to win.
