One tip for fertilizing a lawn is to make sure that the fertilizer is appropriate for the type of lawn, with the correct ratio of nutrients. Using a slow-release fertilizer and using granules also help fertilize a lawn.
Bags of fertilizer have numbers on them that let the buyer know the percentage of nitrogen, phosphorus and potassium, in that order. Most lawns need more nitrogen. Slow-release fertilizer stretches out the amount of time between feeding, and granules applied with a spreader give the homeowner more control. The spreader should be placed on a surface where granules that spill out can't burn the grass. The lawn should also be fertilized when the soil reaches about 55 degrees Fahrenheit or after the danger of frost is over.
