Complete Lawn Fertilizer Schedule by Season
A complete lawn fertilizer schedule includes 3-4 applications: Early spring (April-May) with 20-5-10, late spring (May-June) with 20-0-5, early fall (September) with 20-5-10, and winterizer (October-November) with 22-0-14. Adjust timing by 2-4 weeks based on your USDA zone. Warm-season grasses shift the schedule forward and skip the winterizer. Always base your first application on soil temperature, not calendar dates.
