During the fall, mowing will occur less often—keeping your St. Augustine slightly higher will encourage deeper root growth for winter.
WATERING
Water less as temperatures drop—too much water will lead to disease. Water to prevent drought stress while grass is actively growing and after the beginning stages of dormancy to prevent dehydration.
FERTILIZATION
Fertilize your lawn with the Lawnifi Fall Fertilizer Box for optimal results. The Fall Fertilizer Box was designed to help your grass recover from the heat of summer and prepare for winter dormancy.
WEED CONTROL
Apply pre-emergent herbicides to control winter annual and perennial weeds like chickweed, henbit, Poa annua, crabgrass or goosegrass. Apply post-emergent herbicides only when weeds are present. Since St. Augustinegrass is sensitive to certain herbicides (2,4-D and MSMA), follow label directions and use with caution.
INSECT CONTROL
Check for and control any white grubs. Treat with an insecticide if needed. If you use a granular variety, water the lawn immediately after application to help soil absorption. If drought symptoms or yellow spots occur in a sunny location, check for chinch bug activity. Push a coffee can (with both top and bottom removed) into the ground and fill it with water. Any chinch bugs present will float. Treat for chinch bugs if you have 20 or more chinch bugs per 1,000 sq. ft. If you use a granular variety, water the lawn immediately after application to help soil absorption.
FUNGUS CONTROL
Check for gray leaf spot and brown (large) patch. Treat with a fungicide if needed. If you use a granular variety, water the lawn immediately after application to help soil absorption. Consider mapping those areas because fungicide treatment can be expensive.
When mowing during the summer, never remove more than 1/3 of the leaf blade at a time. If you remove more than that, you will stress the grass and it may go brown for a short time. Taller blades provide more shade for your root system to stay cool and retain moisture during the hot summer days. If you are returning from vacation, you may have to mow multiple times to get the grass back to the desired height. Wait about three to five days between each mowing.
WATERING
Do not over water the grass. St. Augustine 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.
FERTILIZATION
For optimal results, feed your lawn monthly during the summer season by applying the Lawnifi Summer Box liquid fertilizer program.
WEED CONTROL
Apply post-emergent herbicides to control summer annual and perennial broadleaf weeds, such as knotweed, spurge and lespedeza. Since St. Augustinegrass is sensitive to certain herbicides (2,4-D and MSMA), follow label directions and use with caution. If crabgrass and goosegrass are present, make a note to apply a pre-emergent herbicide next spring. Do not apply herbicides during a drought, when grass and weeds are not actively growing or when temperatures exceed 90 degrees. Consider spot treating weeds to avoid burning the grass during hot summer months.
INSECT CONTROL
If drought symptoms or yellow spots occur in a sunny location, check for chinch bug activity. Push a coffee can (with both top and bottom removed) into the ground and fill it with water. Any chinch bugs present will float. Treat for chinch bugs if you have 20 or more chinch bugs per 1,000 sq. ft. If you use a granular variety, water the lawn immediately after application to help soil absorption.
FUNGUS CONTROL
Check for gray leaf spot and brown (large) patch. Treat with a fungicide if needed. If you use a granular variety, water the lawn immediately after application to help soil absorption.
For the first mow of the spring, remove dormant grass leaves to promote new growth by mowing at 2.5 inches in height with a rotary mower that has a sharpened blade. Keep your St. Augustine at 2–4 inches for the rest of spring. Leave clippings on the lawn.
WATERING
Don’t overwater. In the active growing season, St. Augustine needs about one inch of water a week from natural rainfall or irrigation. If you apply any granular fertilizer or control product, you will need to water it in. This is a sufficient amount of water for the week. Overwatering may promote disease outbreak. Conduct an irrigation audit to evaluate how much water is being delivered to different areas of your lawn.
FERTILIZATION
For optimal results, feed your lawn monthly during the fall season by applying the Lawnifi Spring Fertilizer Box.
WEED CONTROL
Apply a pre-emergent herbicide when soil temperatures reach 55 degrees Fahrenheit. This will prevent summer annual weeds like crabgrass and goosegrass from plaguing your lawn and garden. If you notice any current weeds, control them with a post-emergent herbicide. St. Augustine is sensitive to herbicides with 2,4-D, dicamba, MCPP and MSMA. Use a post-emergent herbicide with Atrazine as its active ingredient.
INSECT CONTROL
Apply a broad-spectrum insecticide to prevent spring insects from appearing or to control any current spring insects like chinch bugs or white grubs. White grubs may be active at this time. If you see any white grubs, apply a systemic insecticide.
FUNGUS CONTROL
Apply a systemic fungicide at a preventive rate to keep disease from taking hold of your lawn. You may begin to see circular patches of brown or dead grass as your St. Augustine begins to green up. St. Augustine is also prone to gray leaf spot at this time. Do not apply fertilizer until you’ve applied a systemic fungicide at a curative rate and your grass has recovered.

About 1 inch a week total irrigation spring & summer.
Water deeply, frequently, and in early AM.
WEED CONTROL
Pre-emergents prevent weeds from germinating.
Post-emergents kill weeds after they germinate.
A thick, luch lawn is the best deterrent to weeds.
DISEASE CONTROL
Overly wet grass + shade = fungus problems.
Apply systemic fungicide to prevent fungus outbreaks.
Use multiple fungicide applications to treat affected areas.
INSECT CONTROL
Use a broad spectrum insecticide that controls chinch bugs.
For a once-a-year treatment, July & August are good months.
If using a granular insecticide, water in after application.
Look for insect damage on grass blades and/or roots.
A WORD OF CAUTION FOR NEWLY SODDED LAWNS
A pre-emergent contains a chemical that prevents a weed from putting down roots. Because it is a root inhibitor, it can also negatively affect your new lawn, which is trying to establish itself by putting down roots.
If you successfully killed and removed your old lawn, including all the weeds in it, your newly sodded lawn should have relatively few weeds. It is suggested that you hand pick weeds out of your newly sodded lawn for the first season.
