I have the same problem. It is possible to get a selective weedkiller for clover and other small weeds, and also a different spray to kill paspalum. I used the one for paspalum and it killed other grasses too but with water and fertiliser the main grass in my lawn, couch, quickly took over. Spraying is best done in summer when the main grass you want to encourage is growing strongly. The small oxalis is probably creeping oxalis and it is very difficult to eliminate. Many selective weedkillers say they "control" it - I have had some success with repeated applications but always a patch of it pops up somewhere. Good luck!

Thanks for your reply. Yes I have decided that spraying is the best solution for the worst areas. Just mark off a large area, spray it and resow it. It is the paspalum that I dislike the most.
