Regrow roses!!! "My neighbor has a row of roses, which he took as cuttings. I asked how he took them. He simply plunges the cuttings into the ground. But his secret of success is the humble potato! Before planting cuttings, he pushes the bottom end into a small potato, which he believes keeps the cuttings moist as they develop roots. It sounds crazy, but his row of allotment roses is proof it works." (quote from link)
Having trouble cleaning grout in your home? Use this recipe: 7 cups water, 1/2 cup baking soda, 1/3 cup ammonia (or lemon juice) and 1/4 cup vinegar. The trick is letting it set as long as you can, and then brushing off!
