Tending a lush carpet of grass can consume a gardener, between mowing, weeding and fertilizing the tender blades of grass. As you work to create a green expanse of grass in a landscape, you may notice your grass turning yellow. Yellowing grass is a symptom of a nitrogen deficiency. Make yellow grass green again by fertilizing the lawn with a fertilizer that contains nitrogen. You should notice your turf green up again in no time.
Select a fertilizer that contains approximately half slow-release fertilizer and half quick-release fertilizer. Slow-release fertilizer will promote extended and even growth of the grass and quick-release fertilizer will dump quickly into the grass for fast color improvements.
Fill the broadcast spreader with enough fertilizer to cover your lawn area. Apply 5 lbs. of fertilizer for every 1,000 square feet of lawn in early spring, between 5 and 10 lbs. in early summer, 10 lbs. in late summer and between 10 and 20 lbs. in the autumn. The reason for the increase in fertilization amounts is to prepare the lawn to survive the winter.
Push the broadcast spreader over the lawn in back and forth rows. Overlap the paths of the wheels to ensure even fertilizer application and continue applying the fertilizer to the entire lawn.
Set up the garden hose and the sprinkler to water the grass immediately after you finish applying the fertilizer. Water for approximately 30 minutes to saturate the lawn evenly. Watering will help the fertilizer to soak into the soil and will help prevent fertilizer burn.
Repeat the fertilizing process every eight to 10 weeks to keep your lawn lush and green.
