Note: These tips are written for Bermuda grass lawns — the most common turf in Stillwater. Fescue lawns follow a different calendar. Contact us for a personalized lawn care schedule.
February–March
Apply pre-emergent herbicide before soil temps hit 55°F to stop crabgrass
Scalp Bermuda grass to 1" to remove dormant thatch and speed green-up
Test soil pH — spring is the best time to lime if needed
Trim back ornamental grasses and dead perennial stems before new growth
Clean up winter debris from beds before mulching
April–May
Begin mowing Bermuda once it fully greens up — keep blade at 1.5"–2"
Apply first fertilizer of the season once Bermuda is actively growing
Install fresh mulch in landscape beds — 2–3" depth is ideal
Spot treat broadleaf weeds emerging in lawn with selective herbicide
Seed or sod bare spots before the heat of summer arrives
June–August
Water Bermuda deeply and infrequently — 1" per week is usually sufficient
Mow more frequently during peak growth (every 5–7 days for Bermuda)
Never remove more than 1/3 of the blade height in a single mowing
Apply slow-release summer fertilizer to sustain color through heat
Watch for chinch bugs and brown patch fungus during humid stretches
September–October
Aerate and overseed Fescue lawns in September for best germination
Apply fall pre-emergent to suppress winter annual weeds like henbit
Apply winterizer fertilizer to Bermuda before dormancy to strengthen roots
Complete fall cleanup before first frost — don't leave leaf mats on lawn
Clean gutters after major leaf drop to prevent winter blockages
November–January
Bermuda will go dormant — brown color is normal and healthy, not dead
Avoid heavy foot traffic on dormant Bermuda to prevent compaction damage
Overseeding with ryegrass now provides green color through winter if desired
Plan spring services — book aeration, fertilization, and cleanup early
Inspect fencing, irrigation heads, and landscape features for winter damage
