It’s easy. Select the appropriate injection tip. Set up for injections. Inject. Check. And go. The Wedgle Direct Inject Tree Treatment system features two quick-connect couplers that allows you to easily attach chemical packs to the top of the injection unit and accepts a variety of injection tips on the front. Simply slide back and hold the outer ring, insert a chemical pack or injection tip, then release and the coupler snaps back and locks in place. And that’s why we say you can treat almost any tree in five minutes or less. Click here for our instruction guide or how-to videos.
