Injecting Hardwoods

Wedgle® Injection Tip for Hardwoods
The Wedgle Tip has a wedge-shaped end which deposits chemical where it can most easily be absorbed by the tree—in the cambial zone between the bark and outer ring of sapwood (the xylem). Treat most hardwoods with the standard .75″ tip; the longer 1.5″ tip is ideal for thick-barked trees.
