March Lawn Care Guide for Houston Homeowners

Houston's warm March weather kickstarts rapid lawn growth, making it prime time for maintenance to avoid summer struggles. This guide helps homeowners in Greater Houston, The Woodlands, Katy, and Sugar Land get lush results.

Key March Tasks

Start with pre-emergent herbicides in early March to block weeds like crabgrass, as soil hits 55-65°F. Apply slow-release fertilizers (3-1-2 ratio like 19-4-10) late March for St. Augustine or Bermuda grass common in Houston. Mow weekly at 3.5 inches for St. Augustine, removing no more than one-third blade length.

Fertilization Schedule

Grass Type	Best March Timing	Recommended Product Example
St. Augustine	Late March-Early April	Nitro-Phos Super Turf 19-4-10
Bermuda/Zoysia	End March	Fertilome Southwest Greenmaker 18-4-6

Add trace minerals March-April to boost nutrient uptake after winter stress. Water 1 inch weekly, early mornings to cut evaporation.

Weed and Pest Control

Houston lawns explode with weeds in March—hit broadleaf types with 2,4-D post-pre-emergent. Watch for chinch bugs as grass greens up; spot-treat early. Aerate mid-March if soil compacts to improve roots.

Pruning and Cleanup

Clear winter debris, edge beds, and prune trees/shrubs before full growth. Refresh mulch 2-4 inches deep around plants. These steps prevent pests and diseases as temps climb.
