SEEDING YOUR LAWN

• It's best to seed your lawn in the fall, if possible. Of course, lawn seed can be sown at other times of the year. But fall is the ideal time for seeding to rejuvenate an existing lawn or to start a new one.
  
  
• In most parts of the United States, an existing lawn should be reseeded in late August or early September. This gives the new grass seed time to grow during the cool fall days.
  
  
• Before reseeding thin or bare spots, rake the lawn thoroughly with a broom rake. Use a heavy-duty broom rake with looped spring braces between the handle bar and spacer bar for this type of lawn raking. Broom rakes are available with either flat steel or wire teeth.
  
  
• A multi-purpose rake – sometimes called a double-duty rake – may be ideal for removing a heavy build-up of thatch on your lawn (Fig. 1). The rake's sharp teeth on one side will easily remove the thatch. The flanged teeth on the other side make it easy to pulverize the soil in preparation for reseeding.
  
  
• After the lawn has been thoroughly thatched and raked, the thin and bare spots will be more easily visible. Loosen the soil in any of the bare spots to a depth of about 1" or more with a speedy cultivator or some other type of handy soil-loosening tool (Fig. 2).
  
  
• After loosening and pulverizing the soil in the bare spots, sprinkle the newly prepared area with the proper amount and type of lawn fertilizer. Then, rake it level.
  
  
• If the bare spots have been compacted by heavy traffic, loosen the soil to a depth of about 6". Then, pulverize the soil and add a small amount of peat moss or gypsum to help keep it loose after the reseeding.
  
  
• When the soil is thoroughly loosened and leveled, reseed with a top-quality seed. Select a grass seed mixture that is specially prepared for the type of location you are reseeding. For example, some seed mixtures work well in shady areas, while other mixtures are made for reseeding sunny areas. Ask a salesman in your local retailer's lawn and garden department to help you select the correct seed.
  
  
• Reseed the bare spots by hand (Fig. 3). Reseed the area sparingly – only about six seeds per square inch will survive. Sowing the seed too thickly simply wastes seed and money. After the seeds are sown, spray the area with a light mist of water.
  
  
• Your new grass will get off to a much faster start if you cover the reseeded areas with clear sheets of polyethylene plastic. This covering keeps the moisture in the soil and eliminates the need for constant sprinkling. Secure the edges of the plastic sheet with small rocks, dirt or stakes (Fig. 4).
  
  
• Take care to remove the polyethylene cover when the first seedlings appear. The cover helps the seeds until they germinate, but it will kill all seeds quickly unless it is removed when you see seedlings. After removing the cover, keep the soil moist by spraying it with a light mist two or three times a day until the grass is about 1" high. Continue to water newly seeded areas about once a week until the new grass is about 3" tall
