Seasonal Guides for Your Santee® Centipede Maintenance
SUMMER
Mowing
Santee Centipede should be kept at a mowing height of 1.5–2 inches. When mowing, never remove more than 1/3 of the leaf blade. If you remove more than that, you will stress the grass and it may go brown for a short time. 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. Again, don’t mow below 1.5 inches.
Watering
Do not overwater the grass. Santee 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’s Summer Fertilizer Box or apply Lawnifi Foundation once every three months.
Weed Control
It is not recommended that you apply an herbicide at this time because when temperatures exceed 85 degrees Fahrenheit, the herbicide will damage the grass. Common weeds to look out for include knotweed, spurge, lespedeza, crabgrass, goosegrass, dallisgrass, nutsedge and sandspur.
Insect Control
Check for and control any white grubs. Apply Merit to prevent grub worms and apply GrubEx or Dylox 6.2 to treat grub worms. If you use a granular variety, water the lawn immediately after application to help soil absorption. Calculate that watering into your weekly watering amount. August is the best time to control grubs because they are small and feeding near the soil surface. Other insects to look out for include mole crickets and spittlebugs.
Fungus Control
Disease outbreaks in Santeee are uncommon at this time. Treat with a broad-spectrum fungicide like Heritage if needed. If you use a granular variety, water the lawn immediately after application to help soil absorption. Calculate that watering into your weekly watering amount.

FALL
Mowing
During the fall, mowing will occur less often—keeping your Santee Centipede slightly higher than the regular 1.5–2 inch height 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
For optimal results, feed your lawn monthly during the fall season by applying the Lawnifi’s Fall Fertilizer Box or apply Lawnifi Foundation once every three months.
Weed Control
Apply pre-emergent herbicides to control winter annual and perennial weeds like chickweed, henbit, Poa annua, sedge, crabgrass or goosegrass. Apply post-emergent herbicides only when weeds are present. Since centipede 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.
Fungus Control
It is recommended you apply a fungicide at preventative rates as this will help the grass enter colder months in a healthier condition. If you have had a fungus before, you may need multiple applications in affected areas. Consider mapping those areas because fungicide treatment can be expensive. If you use a granular variety, water the lawn immediately after application to help soil absorption.

SPRING
Mowing
Don’t make the mistake of mowing your Santee centipede lawn too short. Keep your lawn between 1.5–2 inches in height with a rotary mower that has a sharpened blade. Mowing below 1.5 inches will stress your Santee, which may not recover. Never remove more than ⅓ of the leaf blade.
Watering
Don’t overwater. In the active growing season, Santee needs about 1 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 during the spring season by applying Lawnifi Foundation, a granular fertilizer, or 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. Centipede 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 spittlebugs 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 disease outbreaks as your Santee begins to green up. Apply a systemic fungicide for treatment. Do not apply fertilizer until you’ve applied a systemic fungicide at a curative rate and your grass has recovered.

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.
