Spring
Mow your Palmetto St. Augustine between 1.5 and 2.5 inches tall.
Apply pre-emergent herbicide. This will cut down on summer weeds.
If you have had insect problems in the past, treat with broad-spectrum insecticide. If you use a granular variety, water the lawn immediately after application to help soil absorption. Make sure it has control for chinch bugs.
Don’t overwater. In the active growing season, Palmetto needs about one inch of water a week from natural rainfall or irrigation. Too much water can cause fungus.
Apply fungicide if needed. If you have had a fungus or disease in your Palmetto in the past or have quite a bit of shade in the yard, you should apply a systemic fungicide to prevent future outbreaks.

Summer
When mowing, never remove more than 1/3 of the leaf blade at a time. If you need to cut more than 1/3, consider multiple cuts over three to five days.
Do not overwater the grass. Palmetto only needs about one inch of water weekly. Water for longer periods of time, less frequently, and in the early morning hours. Take rainfall into consideration.

Fall
Apply fungicide. This will help the grass enter colder months in a healthier condition. If you have had fungus before, you may need multiple applications in affected areas.
Treat with broad-spectrum insecticide. If you use a granular variety, water the lawn immediately after application to help soil absorption. Make sure it offers control for chinch bugs.
Mow less in cooler fall months. Leave your Palmetto lawn slightly higher than normal to encourage deeper root growth for winter. Adjust mower settings up one notch.
Water less. As temperatures drop grasses don’t need as much irrigation. Too much watering can lead to lawn disease.
If you haven’t had past problems with winter weeds, you can forgo herbicide in the fall. If you do get winter weeds, apply a pre-emergent herbicide for prevention.
