Cement is a fine, soft, powdery-type substance. It is made from a mixture of elements that are found in natural materials such as limestone, clay, sand and/or shale. When cement is mixed with water, it can bind sand and gravel into a hard, solid mass called concrete.
Overview. While onions may be welcome in your vegetable garden, they are considered weeds in your lawn. Onion grass, a type of wild onion, often flourishes in yards, particularly in the southeastern region of the U.S. Like most common lawn weeds, onion grass can be eliminated with commercial herbicides and weed killers.tep 2. Cut onion grass very short to prevent flowering. Onion grass reproduces by flowering and seeding. By cutting onion grass to the same height as your lawn grass, you can stop it from spreading.
Instructions. Remove any visible dirt from the green onions. Dirt commonly collects near the roots of the plants, but may appear on the leaves as well. Peel off any discoloration on the leaves of the green onions. If any leaves have become slimy, remove these as well. Green onions should be firm if not crisp. Place green onions in a strainer and rinse them with cool water. Turn onions to make sure all sides are thoroughly rinsed. Lay out a layer of paper towels on a counter or table surface. When you are done rinsing green onions, lay them gently on the paper towels to dry.
