A good lawn needs adequate nutrients for good growth. Lawns need regular fertilization to keep the grass growing and weeds out. The best way to determine a fertilization program for your lawn is to take a soil test. The report from your sample will be returned by mail and will tell you what mineral elements your lawn needs. Lawns need to be fertilized periodically (several times) throughout the growing season. Fertilizations (feeding) should be made at eight to ten week intervals throughout the growing season.
Fall Fertilization
Research has shown that fall (August or September) and late fall (October, November or December) fertilization is ideal for home lawns. Fertilization during these times will benefit lawns more than any other practice. Most homeowners place too much emphasis on spring and summer fertilization. Some fertilizer is needed during the spring and summer, however, over-application of fertilizer at these times can cause disease and other problems and result in “summer lawn nightmares.”
Advantages of Fall/Late Fall Fertilization
Disease and weed problems are usually less severe when fall and late fall fertilization are practiced. Heat and drought tolerance are usually better, thus enhancing summer lawn quality. Finally, the grass plant produces more root mass and a deeper root system, resulting in an overall healthier plant.
Clipping Removal
It is advisable to return grass clippings to the lawn because they are a valuable source of nutrients. Research has shown that when clippings are removed, a third more nitrogen fertilizer was necessary to maintain the same color and density as areas where clippings were returned. Furthermore, and contrary to popular belief, grass clippings do not contribute to thatch accumulation if the turf is maintained at its recommended cutting height and not more than a third of the leaf surface is removed at one mowing.
