#GardeningTips #GardenHacks #OrganicGardening

Before garden centers existed, people grew everything they ate using methods that cost nothing. Kitchen scraps became fertilizer. Weeds became plant food. Newspaper became mulch. During the Second World War, over twenty million American households grew forty percent of the nation's vegetables without a single commercial product. They used vinegar, coffee grounds, wood ash, old newspapers, and the accumulated knowledge of generations who never needed a store to grow a harvest. The United States Department of Agriculture, Oregon State University, Cornell University, and the University of Arizona Cooperative Extension have all published research confirming these techniques still work. The knowledge was never lost. It was simply made to look outdated. Until now. Here are twenty-five gardening tricks your grandparents used that still work today.
