Just wanting some opinions from any green fingers out there.

So we have an investment property. The tennants are moving out so it gives me about 6months to do as I please until we move in ourselves. Currently there is absolutely no garden or yard, no grass. There is an old BBQ area where years ago flowers must have grown. The area outside the house is full of weeds, those catheads burrs, other burrs etc. So where should I start? There is no safe plaxce for the kids to play, no nice grass, not even a decent place for their swing or tramp. The place is on our farm so we have lots of bore water but no fresh water available for the garden.

DH and I have decided to fence a section in and I will concentrate on that. Plus I also want a vegie garden and we are poor so things we can eat will be a great bonus like corn and pumpkin especially. So would others concentrate on getting some grass growing and the place fenced and leave any pretty flowers until they actually lived there? I can only devote about 1hr Saturday and 1hr Sunday for the time been plus I could water the stuff on a Wednesday. Turf is to expensive but I can get hold of some grass seeds (I can't spell the variety I'm thinking of) or should I turf a small section and hope it spreads? Also as its so full of weeds do I spray them all to kill them first before trying to grow some grass?

Gee its seems so much work I don't know where to start.
