Growing grasses in 1 location for quite a very long time often results in weedy, worn-out soil that can no longer encourage development without frequent replacement of nitrogen. Adding legumes into such a depleted yard might help soften the dirt, avoiding the requirement for constant, expensive fluid treatments. Legumes, besides adding color to a landscape, create nitrogen naturally through a symbiotic relationship with root microbes. Popular legumes to interseed with yard grasses include alfalfa, red clover, white clover, birdsfoot trefoil and sainfoin.
Eliminate the existing grass in the yard by tilling the soil to 6 ins. Any remaining grass will have an established root system and may dominate new seeds.
Rake the tilled ground flat and roll over it with a lawn roller, as seeds should not be planted more than several inches under the ground.
Opt for a commercial seed mixture of beans and grass. The most common combination for lawns is grass and clover.
Fill the seed mixture into a broadcast seed spreader. Roll the spreader over the yard in perpendicular rows, then examine the lawn again in a diagonal direction to prevent a pattern that is visible.
Lightly rake over the ground and roll it over with the roller to blend the seeds to the ground.
Water that the new seed for 10 minutes twice daily for two weeks, providing mild humidity. After two weeks, once growth begins, cut back to five minutes at every watering. When the lawn is established, water just every couple of days.
