Treating Multi Stems as Individual Trees 🤔?
This Ash in West Chester is a MONSTER, the equivalent of 5 Ash most people have on their property. Here’s the mistake most wouldn’t catch :
When a tree splits into multiple stems at or below chest height, most applicators still inject around the root flare and call it a “success.” When injecting Multi Stem trees that low, the product moves up long before it moves sideways.
This means the outside of the canopy is protected, but the product never climbs into the crotch and up the back side of each trunk. So the outside of the canopy gets a full-strength dose, while the center remains unprotected and at risk of decline.
Each of these five trunks gets treated as if it’s an individual tree, with its own canopy to protect. Each one measured separately and dosed by its own DBH. This is the only way the entire canopy stays protected, not just the easy-to-reach edge.
Just like this Ash, you don’t have to lose your trees. You just have to find a company who can treat them correctly.
Tree Preservation starts one stem at a time.
