Re: Weed and rock removal
Don't bother trying to use herbicides on the weeds, all you'll succeed in doing is killing the green parts, it does nothing to the seed in the soil, and ultimately, herbicides pollute the soil and water run-off.
Mow the weeds, if you can't use a mower with a catcher, then use a weedeater, then rake up and discard as much as you can. If you want to kill the weeds, then water the area well, then cover with a dark tarp, the lack of light and heat build up will kill the green stuff.
The rocks, are they native to the soil or were they brought in and used as landscape material that have just gotten out of hand? If the rock is too large and dense to till the soil for leveling and planting, then you're going to have to get most of them out of there. The easiest means will be with a rock screen, you can make one yourself with a few 2x4 and hardware cloth or expanded metal. You build a 2' or 3' wide by 4' or 6' long box with the 2x, then attach the hardware cloth with small fence staples. If you want to get really fancy and make it durable, you wrap the hardware cloth up the outsides of the box and overlay with a 1x, attaching the 1x with screws. This will pinch the cloth and hold it tighter as well as cover any sharp edges that can catch your hands. Once you have the screen, you prop one end up so that the screen sits at an angle. You want just enough angle that as you toss dirt onto it, that it rolls down the screen on it's own. The rock and debris will be shed to the end of the screen, the clean dirt will fall through the screen.
You could also build or buy a trammel screen which is by far easier to use, but that's a whole lot more complicated and expensive.
