Fertilizer Schedule Reality Check: How Much and How Often for a Decent Lawn

Question

Jim thinks fertilizer companies push too many seasonal treatments. Asks real needs for decent lawn.

Answer (Rick, Southern NJ)

Depends on goals (golf course vs. average), irrigation ability, location.

Basic Program (Cool-Season, NJ)

• 3 applications/year with weed control improves appearance 90%+.
• Mow 2–4" per grass type → reduces weeds.
• Lime 2x/year to raise pH.
• Organic option: no weed control, just fertilizer.

Schedule

1. Early Spring (March–April, daffodils blooming): Turf lime + Scotts +Halts (pre-emergent) or plain fertilizer.
2. Late Spring (June): Scotts +2 (post-emergent broadleaf) or plain fertilizer. Wet lawn first, no water 24–48 hrs, then 15 min if no rain.
3. Fall (Mid–Late Sept): Aerate, lime, fertilize (Scotts TB, Ringer, Milorganite—no weed control), overseed sun/shade mix. Keep moist until germination.

Watering Rule

Before 2 PM, not on rainy days.
