Spring Lawn Care: The Complete Checklist
Quick Answer
Spring lawn care follows a strict order: soil test first, apply pre-emergent before weeds germinate, mow for the first time once grass hits 3+ inches, and fertilize only after active green-up begins. Doing these out of order wastes effort or money.
Why the Order of Tasks Matters
Most spring lawn care mistakes aren't about doing the wrong task — they're about doing the right task at the wrong time. Fertilizing before a soil test wastes money on nutrients your soil might not need. Mowing before a pre-emergent has set can break the herbicide barrier. Following a fixed sequence avoids most of this.
The Spring Checklist, In Order
- Soil test (if it's been 2+ years) — confirms pH and nutrient levels before you buy anything
- Rake and clear debris left over from winter — fallen leaves, matted patches, and dead debris block sunlight and airflow
- Apply pre-emergent herbicide before soil holds at 55°F for several consecutive days — see our pre-emergent timing guide
- First mow once grass reaches 3-4 inches and is actively growing, cut back to the correct height for your grass type
- Spot-treat any early broadleaf weeds (dandelion, clover) with a selective post-emergent
- Fertilize once active green-up is confirmed — see our spring fertilizer timing guide
- Check irrigation — inspect sprinkler heads and timers after winter before summer heat arrives
Warm-Season vs. Cool-Season Timing
- Warm-season grasses (Bermuda, Zoysia, St. Augustine): green-up begins in mid-to-late spring — wait for active growth before fertilizing
- Cool-season grasses (Kentucky Bluegrass, Fescue): already growing through spring, so pre-emergent and light fertilizing can start earlier in the season
Not sure which grass type you have?
Check our grass type identification guide before planning your spring schedule — warm- and cool-season timing genuinely conflicts.
Common Spring Mistakes
- Fertilizing warm-season grass before it's actively growing
- Applying pre-emergent after crabgrass has already germinated
- Mowing too short too early, before roots have re-established
- Skipping the soil test and guessing at fertilizer needs
Frequently Asked Questions
A soil test, if you haven't done one in the past 2-3 years — it tells you whether you actually need lime, sulfur, or specific fertilizer before you spend money guessing.
