Peat humus is one of the most overlooked inputs in lawn care—but it may be the key to consistent performance in Oklahoma lawns. While most programs focus on fertilizer, the real issue often lies in how well your soil functions. This article breaks down how peat humus improves soil structure, water retention, and nutrient efficiency, helping lawns handle summer stress and perform more reliably year after year.

Spring scalping Bermuda grass in Oklahoma isn’t about the calendar — it’s about soil temperature. Cutting too early can delay green-up and increase stress, while waiting for consistent warming protects recovery. Learn when to scalp, how low to mow, and why timing matters more than the first warm weekend.

Is your Bermuda grass still brown in March? In Oklahoma, that’s usually a good sign. Warm-season turf stays dormant until soil temperatures consistently rise — and forcing early green-up can create bigger problems later. Here’s what’s really happening beneath the surface and what you should (and shouldn’t) be doing this time of year.

When to apply pre-emergent in Oklahoma depends on soil temperature, not the calendar. Learn the correct spring and fall timing for Bermuda grass, why 55°F and 70°F soil thresholds matter, and how precise application prevents crabgrass and winter weeds before they establish. Proper timing creates predictable, long-term weed control across Tulsa and surrounding areas.
