Has anyone used the Wedgel Direct tree injection system? How did you like it? Did you get good control out of the materials you injected?
Were doing something wrong? Was there adequate soil moisture? Were there leaves? Were you putting the pointy end in the tree?Tried oaks for several days and administered with high hopes and prepared to measure the effectiveness by upper-story tissue analysis (even prepared a phosphorous die to measure dose/translocation distances). It was a study.
Never released a drop, couldn't. Of the Reds, Black, and White oak group.
Now conifers? I can't tell ya.
What are you thinking of treating and with what?
