If you finely chop citrus rinds and sprinkle them on the mulch in your garden, they keep neighborhood cats, dogs and other critters away from your veggies. I guess animals dont like the smell of the orange oil. Ive been using this method in the front garden and its working.
Natural weed killer: 2c white vinegar + 1T dish soap + 1T. salt. Blend and pour into a spray bottle. Will kill anything! (Easily gets rid of all those weeds growing in the cracks and seams of the driveway.)
