Lawn Care Essentials: Watering, Fertilizing, and Weed Control

A beautiful lawn requires consistent effort, especially if your soil is sandy or gravelly. Loamy soil with some clay retains moisture and nutrients better, reducing maintenance.

Soil Improvement for New Lawns

If installing a new lawn on poor soil, incorporate several inches of rich topsoil or compost before seeding. Organic matter improves water retention and nutrient availability, giving grass a strong start.

Fertilization and Weed Control

Use a four-step fertilizer program that includes weed control. In northern regions, two main weed types appear:

• Crabgrass: Apply a pre-emergent herbicide in early spring when soil temperature is below 45°F to prevent germination.
• Broadleaf weeds (dandelions, etc.): Use a selective broadleaf herbicide (often combined with fertilizer) when grass and weeds are damp so the product adheres to weed foliage.

Thick-bladed grasses like quack grass are not controlled by selective herbicides. For these, spot-treat with a non-selective herbicide like RoundUp, then reseed.

Herbicide Application Tips

Use a dedicated sprayer. Adjust the nozzle for large droplets and low pressure to prevent drift. Spray only target foliage. Wait 72 hours before disturbing treated plants—this allows full translocation. Never spray soil; herbicides don't affect seeds.

Seeding: Blends vs. Single Variety

Choose a regional seed blend (e.g., perennial rye, fescue, bluegrass). Blends germinate at different rates—fast growers protect slower ones—and provide disease resistance. Avoid 100% Kentucky bluegrass; its 28-day germination leaves bare soil vulnerable to weeds.

Hydroseeding vs. Hand Seeding

Hydroseeding is not magic—it's just a slurry of seed, fertilizer, mulch, and water. It offers no advantage over hand seeding for home lawns. Straw mulch outperforms hydromulch: it shades seeds, retains moisture, and stays in place during rain. Hand-seeded lawns are cheaper, more reliable, and easier to repair.

Watering New Seed

Whether hydroseeded or hand-seeded, keep the soil constantly moist until germination. Even a few hours of dry heat can kill tender seedlings. Once germinated, the seed is spent—it cannot regrow.
