Does anyone have any experience of using superthrive on an established
tree? I have a large Oak tree that has been lacking TLC for a number
of years... I am going to try and bring it back around.. I hear that
this stuff does work wonders.. My hope is that a combination of
verticle mulching, an application of Mycorrhizae using a Root feeder
and some mulch will help this tree come back to life..

Thank you for any help you can provide
