Answer 2

Easy!  It's called Lasagne!  If you really want to do it right, here is what you do right overtop of that nasty grass -

"......add dolomite lime to the area to neutralize the pH

* Add a layer of animal manure, which can be fresh, for a heavy nitrogen kick

* Lay sections of newspaper or layers of plain cardboard (not coloured) over the entire area, so that the edges overlap

* Add a thick layer of coir (coconut peat), a good moisture retentive substitute for peat, or leaf mulch if available

* Add a layer of ready compost or garden soil

* Add a layer of grass clippings or spoiled hay if available

* Add another layer of coir/leaf mulch

* Finish with a good layer of compost or garden soil for planting in.

Optional - add a dusting of granular organic fertilizer as you build the layers

Answer 3

spray the whole thing with round up next spring, once everything is dead, spread a rich topsoil/ manure on the lawn, then call a landscaper about 'hydro seeding'  

Answer 4

use round up or the equivalent of it. they are great for broad leave weeds.
