Lawn Care Guide: Maintenance, Cost & Seasonal Tips

DIY: $200-$500/year (fertilizer, seed, weed control, equipment maintenance). Professional mowing only: $120-$320/month. Professional treatments (fertilizer and weed control): $300-$800/year (4-6 applications). Full service (mowing + treatments): $1,500-$4,000/year. Aeration and overseeding: $150-$400 (once per year). The biggest factors: lawn size, frequency of mowing, and level of treatment. For most homeowners: a professional fertilizer and weed program ($300-$800/year) combined with DIY mowing is the best value.

Cool-season grasses (Kentucky bluegrass, fescue, ryegrass): Most important: early fall (September). Second most important: late fall (November). Optional: early spring (April). Optional: late spring (May). Warm-season grasses (Bermuda, zoysia, St. Augustine): First application: late spring (when grass greens up and is actively growing). Continue: every 6-8 weeks through summer. Last application: early fall (before grass goes dormant). Key rules: use slow-release fertilizer. Follow the bag directions (more is NOT better, too much fertilizer burns grass and pollutes waterways). Water after applying. Never fertilize dormant grass.

Step 1: Identify the cause. Compacted soil (aerate). Shade (switch to shade-tolerant grass or ground cover). Pest damage (grubs, chinch bugs — treat first). Disease (fungus — treat first). Dog spots (flush with water, reseed). Heavy traffic (reseed and redirect traffic). Step 2: Prepare the area. Rake to remove dead grass and debris. Loosen the top 1/4 inch of soil with a rake. Step 3: Seed. Choose the right seed for your region and sun conditions. Apply seed at the recommended rate. Cover lightly with a thin layer of compost or peat moss. Step 4: Water. Keep the seeded area consistently moist (light watering 2-3 times per day) until grass is established (2-3 weeks). Then gradually reduce to normal watering. Step 5: For large areas, combine with core aeration and overseeding in early fall (cool-season) or late spring (warm-season).

Cool-season grass: every 5-7 days during active growth (spring and fall). Every 7-14 days in summer (growth slows). Warm-season grass: every 5-7 days during active growth (summer). Less frequently in spring and fall. The rule: mow when the grass has grown 1/3 above the target height. Example: if you keep your lawn at 3 inches, mow when it reaches 4-4.5 inches. Never cut more than 1/3 of the blade at once. Mowing too short (scalping) stresses the grass and promotes weeds. Taller grass: deeper roots, more drought-tolerant, shades out weeds.
