Lawn Care Tips for New Homeowners in Hammond, LA

New homeowners in Hammond and Tangipahoa Parish should start with a soil test, identify their grass type, establish a weekly mowing schedule in season, and learn the seasonal fertilization and watering calendar for South Louisiana. The first year is about observation — understanding your specific property before making major changes.

Start With a Soil Test — Not Fertilizer

The most common mistake new homeowners in the Hammond area make is heading straight to the hardware store for fertilizer without knowing what their soil actually needs. Tangipahoa Parish soils vary significantly — from sandy, well-drained soils in elevated areas to clay-heavy, poorly drained spots closer to drainage corridors. Applying the wrong fertilizer at the wrong rate to soil that doesn't need it wastes money and can damage your lawn.

The LSU AgCenter provides soil testing for a nominal fee. The results will tell you your soil's pH, organic matter content, and which nutrients are deficient. Most South Louisiana soils are naturally acidic (pH 5.5–6.5), which suits St. Augustine well. But if your soil pH is off or you're deficient in potassium or iron, you need to know that before building a fertilization program. Professional fertilization services handle this assessment and program design for you.

Know Your Grass Before You Manage It

Most homes in Hammond come with St. Augustine — specifically Floratam — but some older neighborhoods and properties on the edges of town may have centipede, Bermuda, or even a mixed yard. Each grass type requires a different mowing height, fertilizer program, and watering schedule. Mowing St. Augustine at 2 inches (appropriate for centipede) will stress and thin it rapidly. Applying a centipede fertilizer product to St. Augustine won't provide adequate nitrogen.

Once you've identified your grass type, set your mower deck height appropriately: 3.5–4 inches for St. Augustine, 1.5–2 inches for centipede, 1.5–2.5 inches for Zoysia. A consistent lawn maintenance program built around your specific grass type will show results within a single season.

The First-Year Seasonal Calendar

South Louisiana's lawn care calendar differs significantly from what national publications describe. Here's what your first year looks like in Tangipahoa Parish:

• January–February: Minimal mowing. Plan your year — decide if you'll hire help or DIY, order your soil test, inspect irrigation.
• March–April: First fertilization when soil hits 65°F. Start mowing every 10 days, transitioning to weekly by late April.
• May–September: Mow every 7 days. Irrigate during dry spells. Monitor for chinch bugs in July–August. Second and third fertilizer applications.
• October–November: Reduce mowing frequency. Light potassium application. Watch for brown patch.
• December: Mow only as needed. No fertilizer. Consider overseeding with annual ryegrass for winter color.

Common First-Year Mistakes to Avoid

New homeowners consistently make the same set of mistakes their first year. Cutting the grass too short is the most damaging — scalping St. Augustine exposes the soil and stresses the plant badly. Watering every day with short cycles encourages shallow roots and disease. Fertilizing in fall with high-nitrogen products triggers brown patch. And ignoring small pest damage patches lets chinch bugs expand to destroy large turf areas before the problem is recognized.

If you're starting with a neglected property, get a landscaping assessment to understand what you're working with before investing in materials or services. Having a clear plan from the beginning prevents expensive corrections later.
