What “lawn maintenance” means in Meridian (and what it doesn’t)
Seasonal lawn maintenance calendar for Meridian, Idaho
| Season | Primary goals | High-impact tasks | Common mistakes to avoid |
|---|---|---|---|
| Early Spring
(Mar–Apr)
|
Wake-up, weed prevention, steady growth | Pre-emergent timing for spring annual weeds, light feeding, mower tune-up, sprinkler inspection | Over-fertilizing too early; mowing too short “to reduce mowing” |
| Late Spring
(Apr–May)
|
Root development, density, irrigation readiness | Core aeration (great window), spot weed control, irrigation scheduling adjustments | Watering daily in short bursts; ignoring dry spots from poor sprinkler coverage |
| Summer
(Jun–Aug)
|
Stress management, efficient water use | Deep/infrequent irrigation, higher mowing height, targeted pest monitoring (including lawn insects) | Big nitrogen pushes in extreme heat; watering mid-day; scalping |
| Early Fall
(Late Aug–Oct)
|
Repair, thicken, build roots for next year | Core aeration + overseeding, major fertilization window, broadleaf weed cleanup | Missing the window (waiting until it’s cold); overwatering new seed |
| Late Fall & Winter
(Oct–Feb)
|
Protect investment, prevent freeze damage | Sprinkler blow-outs/winterization, leaf management, traffic reduction on frozen turf | Skipping blow-outs; letting leaves mat down and smother grass |
