Those of you pining
for a registered organic
weed control spray for the home market are in luck with this latest offering from the people at Amgrow.
Amgrow Organix Weed Blitz 1L ready to use - $14.95.
The active ingredient of this herbicide is pine oil, extracted from both Australian and New Zealand pine. It works by stripping the coating from leaves, stems and even seeds to which it is applied, causing the collapse of the cells and thus the plant itself. It is wholly plant-derived and certified organic. If you understand it's action you can now understand why it would not be the best solution to bulbous or woody perennial weeds which would burn-off then most-likely recover. It does, however, work an absolute treat in killing juvenile perennial as well as most annual weeds.
