Homemade Crabgrass Killer: Select an old sock or nylon; pour baking soda into it. The amount you need depends on the size of the patch. More is not necessarily better; you just want enough to coat the leaves. Prepare the weeds by misting with a garden hose. Lean over the crabgrass and tap the baking soda out of the sock. Strike it with your hand and let the dust settle on the leaves. Coat the entire patch and wait a day or two. The crabgrass should turn black and die.
PSA: Kills Dandelions ... Doesn't Kill your Kids or Pets! 1/2 gallon of Apple Cider Vinegar 1/4 c table salt 1/2 tsp Dawn liquid dish soap Mix above ingredients in a spray bottle. Spray weeds thoroughly. The Dawn dish soap strips the weed of its protective oils so the vinegar can work with deadly force. Actually better than insecticides you buy at hardware store.
Homemade Treatment for dried out grass ....no joke, my neighbor uses this and his lawn is a lush green carpet even after our 3 weeks of 100* and no rain.

"Spray your weeds with diluted vinegar...not only will it kill them, but the plants and soil love it. Read how here, and see the before and after pictures. I just learned about this in my winter gardening class the other day and the teacher has done it for years." Brilliant, and so much safer for my kids to be around!
Start putting in your plants; work the nutrients into your soil. Wet newspapers and put layers around the plants overlapping as you go; cover with mulch and forget about weeds. Weeds will get through some gardening plastic; they will not get through wet newspapers.
