You can thicken new grass by using fertilizer, watering it 1 to 1½ inches per week, mowing when it is at an optimal height, and preventing weeds. You should fertilize your grass while you plant the grass seed, or soon afterward. Use an herbicide to prevent weeds or spot spray with herbicide to kill existing weeds.

If you apply too much fertilizer to your grass, it can take about three weeks to recover. If you still have dead patches after three weeks, it might be time to remove the dead grass and overseed the affected area. Since overfertilizing can also cause problems with fungus, leading to further damage to the grass, monitor your grass color and growth for one month after over fertilizing.

The best time to apply fertilizer to your lawn is in early fall, though some climates necessitate a different schedule. In most cases, avoid fertilizing late into fall, as this opens up your yard to winter injuries and poor health (though this is a great time to kill weeds.) You should avoid early spring fertilization, as this helps the grass leaves grow, but at the expense of developing root systems. Remember to water your lawn after fertilizing to increase its effectiveness and reduce the likelihood of runoff during a rainstorm. 

Each season’s climate influences approaches needed for effective suppression.
