Central NJ cool-season lawns are best fertilized in early fall (the most important feeding) and again in spring, on a program timed to the weather. Results vary by lawn, weather, and timing, and we follow all product labels.
The NJ fertilizing calendar (simple version)
- Early spring: a light feeding to green up as growth starts.
- Late spring: optional, depending on the lawn.
- Early fall: the big one — roots store energy for winter and a strong spring.
- Late fall: a “winterizer” feeding where appropriate.
Why fall feeding matters most
Cool-season grass does its real growing in fall. Feeding then builds deep roots and a thicker lawn that resists weeds and summer stress next year.
DIY vs. a program
Store fertilizer works, but timing and rate are easy to get wrong (and over-applying can burn the lawn or run off). A fertilization & weed control program handles the calendar and rates for you.
