This really works - we did it for our raised beds and regular garden, no weeds for two years!! The newspaper will prevent any grass and weed seeds from germinating, but unlike fabric, it will decompose after about 18 months. By that time, any grass and weed seeds that were present in the soil on planting will be dead. It’s green, it’s cheaper than fabric, and when you decide to remove or redesign the bed later on, you will not have the headache you would with fabric. (another pinner said)
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.
Natural Weed Killer 1 gallon vinegar, 1/2 cup salt, dash of dish washing detergent (makes it stick to the weeds). Mix well, spray on weeds in the morning, rejoice in their death that evening. This works best on a sunny day.
