Watering
If turf grass becomes too dry in its dormant stage, it can and will die. In fact, more Texas turf is lost during winter to desiccation (complete dryness) than to freeze damage. Be sure to water your lawn at least once every three or four weeks during winter if there hasn’t been enough rain or snow. A dry lawn is likely to be damaged more by low temperatures than a well-watered lawn.
As the lawn starts to break out of dormancy and green up in later winter and early spring, it’s critical to keep it well watered. Turf grass is composed of plants that generate new roots, stems, and leaves during this transitional time.
Fertilize
4 TIMES A YEAR
Apply a simple 15-5-10 for an early green-up. Most companies that make slow-release fertilizers also make a non slow-release 15-5-10 that provides for a quick two-week green up before we get to the heart of the fertilizer schedule.
Late February - Early March
Fungicide
2 TIMES A YEAR
Gray Leaf Spot is a blotchy spot on the grass blade leafs. (mostly on St. Augustine lawns) Use fungicides with active ingredients like Daconil, Consan or Banner.
To control the dreaded brown patch fungal disease (symmetrical brown circles in the grass), use a systemic lawn fungicide. Apply at the first sign of disease and reapply as needed, typically 2–3 times, following label instructions.
Herbicide
3 TIMES A YEAR
Use pre-emergent herbicides, to prevent the weeds that we experience in February and March.
Use pre-emergent controls for grassy weeds again, to prevent such weeds as Crabgrass, Goosegrass and Dallisgrass from popping up late in the spring and summer.
One more application of a grassy pre-emergent will keep fall weeds from invading from August on.

Insecticide
Insecticides should only be applied when a problem is present. Be prepared for chinch bugs from spring to early summer and grub worms from late summer to early fall. Damage may appear as irregular-shaped spots in the lawn along concrete areas. Spot-treat with a liquid insecticide and follow with a granular application if needed, per label instructions. Area needs constant monitoring.
LAWN CARE QUICK TIPS
Apply slow-release 3-1-2 ratio fertilizers.
Apply slow-release 3-1-2 ratio fertilizers. (recommended formulations 19-5-9, 19-4-10, 18-4-6, 15-5-10.)
If turf grass looks yellow (chlorosis) or necrotic, use an application of either granular or liquid iron. Once a year should be enough.
Apply winterizer formulas for winter hardiness. Ratios vary, but make sure they are “winter” or “fall” formulas designed for southern grasses. (examples: 18-6-12, 8-12-16, 10-5-14) Will make lawns winter-hardy.
