it's a Zenport tool that I got recently- trying to use it, but still difficult, the areas of contact is within that 1/2", and my fingers are fat, so I figure to use a paper clip to secure it and left undisturbed. Fat roots in the ground are very juicy, they carry a lot for the big tree, so, it may work... shall see with time here. the problem we have is the weather, already raining and cold again, so I will go put more mulch in there...hope it generates the heat it needs to bond.
