Do not fertilize your lawn yet. Mow your lawn at least three times or wait until about April 15. After that time, consider applying a 19-5-9 synthetic fertilizer or a 4-2-3 organic analysis.

Tune up your lawnmower, and be sure the blade is properly sharpened. A properly sharpened lawn mower blade cuts the grass; a dull blade tears the grass blades.

It’s a good time to re-sod or plant grass. If you have any shady or semi-shaded areas, you must use a St. Augustinegrass or a ground cover. The best and only St. Augustine grass which should be planted in this area is the Flora-TAM St. Augustine.

If your St. Augustine is a little chlorotic (yellow), try six tablespoons of iron sulfate dissolved in one gallon of water used as a spray. It’s not a cure-all, just a quick picker-upper. For long term greening and prevention of yellowing, consider Texas Green Sand at a rate of 10-20 pounds per 1,000 square feet.

Start the automatic sprinkler system if we have not had rain for two weeks.
