Due to my neglect of it out of frustration i now have what can only be described as weed trees.
Id need a slasher to mow this, so every weekend i got get a pair of diaposable overalls and don a face mask and the poor whipper snipper is on max revs for about 2 hours and 2 full tanks.
2 weeks ago i bought 200kg of pool salt and put it on some weeds in the front yard and seems this has put the weeds in their place ie dead.
I want to cover my whole block with it and perhaps just blue metal on top but this will take a LOT of salt.
Ideas would be good if anyones done this, Ive never felt so defeated at something so stupid.

How many square metres are we talking about?
