The Four Seasons of Lawn Care
Lawn care follows a predictable annual cycle, but the specific timing shifts depending on whether you grow cool-season grass (bluegrass, fescue, rye) or warm-season grass (bermuda, zoysia, st. augustine). The biggest mistake homeowners make is applying the right treatment at the wrong time. Heavy spring nitrogen on cool-season lawns, for example, produces lush top growth that collapses in summer heat.
| Season | Cool-Season Priority | Warm-Season Priority | Key Tasks |
|---|---|---|---|
| Spring | Pre-emergent, light fertilizer | Green-up fertilizer, mowing start | Crabgrass prevention, soil testing, first mow |
| Summer | Water deeply, raise mowing height | Monthly fertilizer, pest control | Grub prevention, deep watering, weed spot-treatment |
| Fall | Aerate, overseed, winterizer | Last nitrogen, pre-emergent for winter weeds | Core aeration, overseeding, fall fertilization |
| Winter | Equipment maintenance, planning | Dormancy management, winter weed watch | Sprinkler winterization, tool sharpening, soil testing |
Timing Is Everything
Every lawn care task has an optimal window that’s driven by soil temperature, not the calendar date. Pre-emergent herbicide works when soil reaches 55 degrees for 3 consecutive days. Overseeding succeeds when soil is between 50 and 65 degrees. Fertilizer is most efficient when the grass is actively growing, not dormant.
