Lawns can be fertilized organically by using compost and mulching mowers. But for those who prefer chemical fertilizers, Scotts provides a lawn fertilizing schedule. Many experts, however, recommend a lighter feeding in spring and a heavier one in late fall for cool-season grasses. Too much fertilizer in spring can lead to disease and weed problems. And if you have, indeed, already fertilized in late fall, your lawn is still "digesting" that fertilizer in spring.
In addition to the above tasks of spring lawn care, don't forget weed control and making sure your mower is ready for the mowing season.
